Abstract
Artificial insemination (AI) plays a critical role in facilitating rapid genetic and production gains within the sheep industry. However, variable rates of AI success remain a concern for the industry and a barrier to adoption. Furthermore, the degree to which female factors influence the success of intrauterine laparoscopic AI rather than natural mating remains unknown. As such, this study investigates the effect of several factors collected during the time of AI, on the success of intrauterine laparoscopic AI. Data was generously donated by artificial breeding companies and stud breeders during routine commercial AI operations. AI data was collected over 3 breeding seasons during commercial AI programs (N = 24 programs) using Merino ewes (N = 24,700). Sire ID (N = 253), time of AI following progesterone removal (approx. 43-59 h post removal), uterine tone and intra-abdominal fat (both scored 1-5) as well as age of the ewe were all recorded at the time of AI. Transcutaneous ultrasound subsequently determined pregnancy rate approximately 55 days post-AI. A multivariate regression analysis was performed and revealed pregnancy success to increase when semen was inseminated into a ewe with a uterine tone score of 4 or 5 (P < 0.001). The remaining factors fell short of significance within the multivariate model. An interclass coefficient variation matrix was also used to determine the proportion of variation contributed to AI success by random factors allocated in the model; site, sire, AI date and breeding season (45.99 %, 29.94 %, 15.15 % and 8.92 %, respectively). These results highlight the influence of uterine tone on ewe fertility following laparoscopic AI, but also that program location and the sire used can further modify this influence on pregnancy rate. These factors must now be considered in combination with semen factors per individual sire used during AI to ascertain the contribution of several factors to the success of laparoscopic AI in Australia.

Abstract
This study aimed to determine the influence of heat stress during the dry period on milk yield and reproductive performance of Holstein cows in a hot environment. Breeding and milk production records of cows, as well as meteorological data between 2017 and 2020 from a commercial dairy herd (n = 12,102 lactations), were used to determine the relationship between climatic conditions during the dry period (average of the temperature-humidity index (THI) at the beginning, middle, and end of the dry period) and reproductive efficiency and milk yield traits. THI was divided into < 70 (no heat stress), 70-80 (moderate heat stress), and > 80 (severe heat stress). First-service pregnancy rate of cows decreased (P < 0.01) with increasing hyperthermia during the dry period (9.5, 7.3, and 3.4% for THI < 70, 70-80, and > 80, respectively). All-service pregnancy rate was highest (P < 0.01) for cows not undergoing heat stress during the dry period (60.2%) and lowest (42.6%) for cows with severe heat stress during the dry period. Cows not experiencing heat stress during the dry period required a mean ± SD of 5.6 ± 3.8 services per pregnancy compared with 6.5 ± 3.6 (P < 0.01) for cows subjected to THI > 80 during the dry period. Cows not suffering heat stress during the dry period produced more (P < 0.01) 305-day milk (10,926 ± 1206 kg) than cows subjected to moderate (10,799 ± 1254 kg) or severe (10,691 ± 1297 kg) heat stress during the dry period. Total milk yield did not differ (P > 0.10) between cows not undergoing heat stress (13,337 ± 3346 kg) and cows subjected to severe heat stress during the dry period (13,911 ± 4018 kg). It was concluded that environmental management of dry cows during hot months is warranted to maximize reproductive performance and milk yield in the following lactation.

Abstract
Objective This study aimed to assess the effect of increased omega-3 consumption on fertilization rates and the probability of women getting pregnant. This study is needed because different perspectives exist regarding the use of omega-3 fatty acids in enhancing fertility among women with reproductive issues, and information for those planning a spontaneous pregnancy is limited. Methods PubMed, Clinical Trials, CINAHL/EBSCO, Medline Complete, Cochrane Library, and Google Scholar were searched for articles published until April 2021, and the search was limited to articles in English language. The search strategy included the following key words: "in-vitro fertilization (IVF)," "intracytoplasmic sperm injection techniques (ICSI)," "pregnancy," "omega-3 fatty acid," "alpha-linolenic acid," "eicosapentaenoic acid," "docosahexaenoic acid," "n-3 polyunsaturated fatty acid," and "fish oil and seafood." Studies reporting female fertility occurring naturally or IVF/ICSI concurrent with omega-3 intake were included. Retrospective studies, studies including postmenopausal women, and unevenly matched control and study groups were excluded. To assess bias, we used the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.0. To synthesize the findings from the studies included in this review, a meta-analysis was conducted using calculated or extracted odds ratios (OR) of clinical pregnancies and fertilization rates for each group in each study. Results We included six trials involving 1789 women who received fertility treatment, four trials involving 2607 women who conceived naturally, and three trials involving 1725 oocytes for fertility rates. Aggregated ORs for the effects of omega-3 on pregnancies were 1.74, 1.36, and 2.14 for women who received fertility treatment, those who conceived naturally, and fertilization rate, respectively. All these results were significant (p ≤ 0.01), although they had high heterogeneity I2>68 %. Conclusion This systematic review and meta-analysis suggest that omega-3 intake significantly improves women's pregnancy and fertilization rates; however, the high heterogeneity in this review somewhat limits its interpretation. Therefore, further prospective randomized studies are necessary to better understand this relationship.

Abstract
PURPOSE Nifedipine is a calcium channel blocker with smooth muscle relaxing properties. This study set out to investigate the efficacy of nifedipine administered orally before embryo transfer (ET) on the improvement of the intracytoplasmic sperm injection (ICSI) outcome. This randomized, double-blind, comparator-controlled, was carried out between 2019 and 2020 in the infertility center of Babol, Iran. 200 women candidates for ICSI and recipients of frozen-thawed ET aged 18-40 years were randomly assigned in the ratio 1:1 to an intervention group that received nifedipine 20 mg tablets orally 30 min before ET (n = 100) or to a group of placebo (n = 100). A randomization center in Babol University of Medical Science used computer-generated numbers to allocate treatments. The allocation treatment was blind to the participants, the sonographer of endometer monitoring, the staff of the ICSI laboratory, and the outcome assessor. The primary analysis was based on the intention-to-treat principle done on 200 participants, (n = 100), comparing chemical pregnancy rates in the two comparing groups at 14 days' follow-up after ET. Implantation rate and clinical pregnancy were considered secondary outcomes. RESULT 200 participants were analyzed. There is no significant difference in the number of oocytes and the quality of embryos in the nifedipine and placebo groups. Despite a numerical increase in the rate of chemical pregnancy, there were no statistical differences in the study group versus the comparison group (24% vs 14%, P = 0.1, rate ratio 0.88, 95% CI 0.77 to 1.01), respectively. Also, no significant increase in clinical pregnancy was found compared with the placebo (17% vs 8%, P = 0.26, rate ratio 0.90, 0.81 to 1.00). CONCLUSION Nifedipine administered orally 30 min before embryo transfer did not improve the chemical pregnancy rate, and clinical pregnancy rate in infertile women undergoing ICSI. This trial has been registered on the Iranian Clinical Trials Registration Site (IRCT) with the number IRCT20180417039338N3.

Abstract
Two studies were conducted to evaluate the effects of the follicular wave on ovarian function and fertility in dairy heifers and lactating cows. In study 1, the estrous cycle of the selected Holstein heifers was initially synchronized using two intra-muscular prostaglandin F2α (PGF2α) administrations 11 days apart. Heifers in group FFW (n = 14) received an intra-muscular 500 μg PGF2α administration on day 7 after detecting standing estrus, while Heifers in group SFW (n = 14) were administered PGF2α 13 days after detecting standing estrus. The pregnancy rates of FFW (n = 98) and SFW (n = 100) heifers were also determined 35-37 days after artificial insemination (AI). In Study 2, healthy Holstein lactating cows (n = 28) were randomly assigned to either the FFW (n = 14) or SFW (n = 14) groups. The estrous cycles of the cows were presynchronized using two intra-muscular administrations of PGF2α given 14 days apart. Then, the emergences of the follicular waves were induced using an Ovsynch protocol. The pregnancy rate of FFW (n = 99) versus SFW (n = 98) cows was also determined 35-37 days after AI. The ovulatory follicle and corpus luteum (CL) resulting from the ovulatory follicle of FFW were larger than those of the dominant follicle and the CL of SFW in dairy heifers and lactating cows. However, the pregnancy rate did not differ between the FFW and SFW groups in heifers and lactating cows 35-37 days after AI. In conclusion, although the characteristics of the ovulatory follicles in FFW versus SFW animals differed, the follicular wave in dairy heifers or lactating cows did not affect fertility.

Abstract
BACKGROUND Endometriosis frequently results in pain and infertility. While conservative surgery offers some relief, it often falls short of ensuring satisfactory pregnancy outcomes. Adjuvant GnRH-a is administered post-surgery to mitigate recurrence; however, its impact on pregnancy outcomes remains debated. This study endeavors to assess the efficacy of adjuvant GnRH-a in enhancing pregnancy outcomes post-conservative surgery in endometriosis patients. METHODS Databases including PubMed, Embase, the Cochrane Library, Medline (Ovid), Web of Science, and Scopus were rigorously searched up to 02 August 2023, without linguistic constraints. Identified articles were screened using strict inclusion and exclusion criteria. Evaluated outcomes encompassed pregnancy rate, live birth rate, miscarriage rate, ectopic pregnancy rate, multiple pregnancy rate, mean postoperative pregnancy interval, recurrence rate, and adverse reaction rate. The Cochrane risk of bias tool and the Jadad score evaluated the included studies' quality. Subgroup and sensitivity analysis were implemented to analyze the pooled results. A meta-analysis model expressed results as standardized mean difference (SMD) and Risk ratio (RR). RESULTS A total of 17 studies about 2485 patients were assimilated. Meta-analysis revealed that post-surgery, the GnRH-a cohort experienced a marginally elevated pregnancy rate (RR = 1.20, 95% CI = 1.02-1.41; P = 0.03) and a reduced mean time to conceive (RR = -1.17, 95% CI = -1.70- -0.64; P < 0.0001). Contrarily, other evaluated outcomes did not exhibit notable statistical differences. CONCLUSIONS Incorporating adjuvant GnRH-a following conservative surgery may be deemed beneficial for women with endometriosis, especially before Assisted Reproductive Technology (ART). Nonetheless, owing to pronounced heterogeneity, subsequent research is warranted to substantiate these potential advantages conclusively. REGISTRATION NUMBER CRD42023448280.

Abstract
PURPOSE Selecting the optimal blastocyst to implant during cryopreservation and warming is critial for in vitro fertilization success. Therefore, the aim of this study was to explore which blastocyst should be prioritized to be thawed when facing a single vitrified blastocyst on day 5 transfer. METHODS A retrospective study including 1,976 single vitrified-warmed blastocyst transfer cycles was conducted from January 2016 to December 2020. RESULTS We found that grade 4 vitrified blastocyst had a higher clinical pregnancy (60.64% vs. 49.48%, P < 0.001) and live birth rates (50.12% vs 39.59%, P < 0.001) than the grade 3 vitrified blastocyst. However, no statistical difference was found between groups in miscarriage rate, birth weight, or gestational age. Besides, the grade 4 vitrified-thawed blastocyst had significant potential to develop into grade 6 blastocyst after further culturing for 16 h (73.68% vs. 48.60%, P < 0.001). The grade 6 transferred blastocyst was markedly higher in both clinical pregnancy rate (61.88% vs. 51.53%, P < 0.001) and live birth rate (50.91% vs. 40.46%, P < 0.001) compared to grade 5 transferred blastocyst. CONCLUSIONS Grade 4 vitrified blastocyst is recommended when facing single vitrified blastocyst on day 5 transfer. More importantly, the "embryonic escape hypothesis" was firstly proposed to reveal the findings.

Abstract
Semen sexing is among one of the most remarkable inventions of the past few decades in the field of reproductive biotechnology. The urge to produce offspring of a desired sex has remained since traditional times. Researchers have tried many methods for accurate semen sexing, but only the flow cytometry method has proved to be effective for commercial utilization. However, there were always concerns about the effects of sexed semen, especially on fertility and the rate of genetic gain. Some concerns were genuine because of factors such as low semen dosage in sexed semen straws and damage to sperm during the sorting process. Various researchers have conducted numerous studies to find out the effect of sexed semen on fertility and, in this article, we reflect on their findings. Initially, there were comparatively much lower conception rates (∼70% of conventional semen) but, with refinement in technology, this gap is bridging and the use of sexed semen will increase over time. Concerning genetic gain with use of sexed semen, a positive effect on rate of genetic progress with the use of sexed semen has been observed based on various simulation studies, although there has been a mild increase in inbreeding.

Abstract
RESEARCH QUESTION Do embryos warmed using a one-step rehydration protocol with a more efficient workflow result in comparable pregnancy rates to the standard multi-step rehydration protocol? DESIGN A retrospective cohort study of 3439 frozen embryo transfers (FET). Clinical outcomes of 833 FETs using a one-step rehydration protocol were reviewed and compared with results from the control group (2606 FETs using standard multi-step rehydration protocol). Primary outcome was ongoing pregnancy rate. Secondary outcomes were survival, positive pregnancy, clinical pregnancy, implantation and miscarriage rates. RESULTS Survival rates were identical between the two groups (99.5%). Clinical pregnancy rate was 63.0% in the one-step warming protocol, comparable to 59.9% in the multi-step rehydration protocol. A significant increase was observed in the ongoing pregnancy rate with 60.4% in the one-step rehydration versus 55.4% in the multi-step rehydration group (P = 0.011); implantation rate was 63.6% versus 57.0% (P = 0.0005). The miscarriage rate of 4.0% in the one-step rehydration protocol was significantly lower compared with 7.6% in the multi-step rehydration protocol (P = 0.0001). Comparable outcomes persisted even when the analysis was extended to embryos that had and had not undergone preimplantation genetic testing (PGT), as well as day of development of the blastocysts. When controlling for variables of age, PGT, blastocyst development day and embryo expansion, rapid warming significantly increased chances of an ongoing pregnancy (adjusted OR 1.264, 95% CI 1.076 to 1.484). CONCLUSION A one-step rehydration protocol resulted in identical survival rates and improved ongoing pregnancy rates compared with the multi-step rehydration technique.

Abstract
Objective Recently, oral antioxidants in combined forms have been used to treat men with idiopathic infertility. This study aimed to evaluate the effects of treatment with vitamin C, vitamin E, selenium, zinc, arginine, L-carnitine, and coenzyme Q10 on sperm quality parameters, DNA integrity, reproductive hormones, and pregnancy rates in men with infertility and idiopathic oligoasthenoteratozoospermia (OAT). Methods A prospective study was conducted on 420 men with infertility and idiopathic OAT who took an oral supplement of antioxidant SP-Power tablets twice daily for 6 months. Semen quality, reproductive hormones, and the DNA fragmentation index (DFI) were evaluated at baseline and at 3 and 6 months after supplementation, using the World Health Organization 2021 guidelines. Results No significant difference was observed in volume or the percentage of typical morphology during treatment. A significant improvement in sperm concentration was observed after supplementation (8.67±1.41, 12.17±1.91, and 19.01±0.86 at baseline, 3, and 6 months respectively, p<0.01). The total motility, progressive motility, and total motile sperm count also increased significantly (p<0.01), whereas the DFI decreased after 6 months. There was an increase in normal FSH levels and testosterone levels after 6 months of supplementation of antioxidant SP-Power but these differences were not statistically significant (p=not significant and p=0.06, respectively). Conclusion Supplementation with SP-Power tablets improved sperm quality parameters, sperm DFI, some reproductive hormones, and pregnancy rates in men with infertility and idiopathic OAT, which could be attributed to the supplement's synergistic antioxidant action. Further studies are needed to determine the effects of supplementation on oxidative stress markers.

Abstract
BACKGROUND Letrozole has been proven to be an effective method for inducing ovulation. However, little attention has been paid to whether the lead follicle size will affect the success rate of intrauterine insemination (IUI) with ovulation induction with alone letrozole. Therefore, we hope to investigate the effect of dominant follicle size on pregnancy outcomes on human chorionic gonadotropin (hCG) day of the first letrozole-IUI. METHODS A retrospective cohort study design was employed. We included patients with anovulation or unexplained infertility undergoing first IUI treatment with letrozole for ovarian stimulation. According to the dominant follicle size measured on the day of hCG trigger, patients were divided into six groups (≤ 18 mm, 18.1-19.0 mm, 19.1-20.0 mm, 20.1-21.0 mm, 21.1-22.0 mm, > 22 mm). Logistic models were used for estimating the odds ratios (ORs) with their 95% confidence interval (CIs) for achieving a clinical pregnancy or a live birth. A restricted cubic spline was drawn to explore the nonlinear relationship between follicle size and IUI outcomes. RESULTS A total of 763 patients underwent first letrozole-IUI cycles in our study. Fisher exact test showed significant differences among the six follicle-size groups in the rates of pregnancy, clinical pregnancy and live birth (P < 0.05 in each group). After adjusting the potential confounding factors, compared with the follicles ≤ 18 mm in diameter group, 19.1-20.0 mm, 20.1-21.0 mm groups were 2.3 or 2.56 times more likely to get live birth [adjusted OR = 2.34, 95%CI (1.25-4.39); adjusted OR = 2.56, 95% CI (1.30-5.06)]. A restricted cubic spline showed an inverted U-shaped relationship between the size of dominant follicles and pregnancy rate, clinical pregnancy rate, and live birth rate, and the optimal follicle size range on the day of hCG trigger was 19.1-21.0 mm. When the E2 level on the day of hCG trigger was low than 200 pg/mL, the clinical pregnancy rates of 19.1-20.0 mm, 20.1-21.0 mm groups were still the highest. CONCLUSIONS The optimal dominant follicle size was between 19.1 and 21.0 mm in hCG-triggered letrozole-IUI cycles. Either too large or too small follicles may lead to a decrease in pregnancy rate. Using follicle size as a predicator of pregnancy outcomes is more meaningful when estrogen on the day of hCG trigger is less than 200 pg/ml.

Abstract
RESEARCH QUESTION What is the success rate of intrauterine insemination (IUI) after failing IVF? DESIGN This retrospective cohort study evaluated the pregnancy outcomes of 551 patients who underwent a total of 992 IUI cycles at an academic fertility centre between October 2008 and April 2018. RESULTS The study participants (n = 551) had previously failed one to three fresh IVF cycles and any resultant embryo transfers, and subsequently underwent a total of 992 IUI cycles. When comparing demographics, women with ongoing pregnancies, clinical pregnancies and positive pregnancies were significantly younger (P = 0.037, P = 0.025 and P = 0.049, respectively) compared with women who did not conceive. The cumulative ongoing pregnancy rate for all IUI cycles was 7.44% per patient (41 pregnancies in 551 patients), and the ongoing pregnancy rate after the first IUI cycle was 4.72%. In single women who had previously failed six IUI cycles before undergoing IVF cycles with donor sperm, the cumulative ongoing pregnancy rate was 15.8% in donor sperm IUI cycles compared with 5.1% in women who used their partner's sperm for both IVF and IUI cycles, with an adjusted odds ratio of 6.1. Patient age, number of previous pregnancies, daily gonadotrophin dose for IVF, number of mature follicles at trigger, and number of failed IVF cycles failed to predict pregnancy outcomes. CONCLUSION Ongoing pregnancy following IUI after failed IVF occurs at a rate of approximately 5% per cycle, and this rate is higher if donor sperm is used for both IVF and IUI cycles. This can be considered with proper counselling in women aged <40 years, and may be discouraged in women aged ≥43 years.

Abstract
PURPOSE To evaluate the effects of acupuncture on IVF-ET outcomes. METHODS Digital databases, including Pubmed, Embase, the Cochrane Library, the Web of Science and ScienceDirect, were searched from their inception to July 2022. The MeSH terms we used included: acupuncture, in vitro fertilization, assisted reproductive technology and randomized controlled trial. The reference lists of relevant documents were also searched. The biases of included studies were assessed by the Cochrane Handbook 5.3. The major outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR). The pregnancy outcomes reported in these trials were pooled and expressed as risk ratios (RR) with 95% confidence interval (CI) in the Review Manager 5.4 meta-analysis software. Heterogeneity of the therapeutic effect was evaluated with a forest plot analysis. Publication bias was assessed by a funnel plot analysis. RESULTS Twenty-five trials (a total of 4757 participants) were included in this review. There were no significant publication biases for most of the comparisons among these studies. The pooled CPR (25 trials) of all the acupuncture groups (43.6%) was significantly higher than that of all the control groups (33.2%, P < 0.00001), and the pooled LBR (11 trials) of all the acupuncture groups (38.0%) was significantly higher than that of all the control groups (28.7%, P < 0.00001). Different acupuncture methods (manual acupuncture, electrical acupuncture and transcutaneous acupoint electrical stimulation), acupuncture time (before or during the time of controlled ovarian hyperstimulation and around the time of embryo transfer), and acupuncture courses (at least 4 sessions and less than 4 sessions) have respectively positive effects on IVF outcomes. CONCLUSION Acupuncture can significantly improve CPR and LBR among women undergoing IVF. Placebo acupuncture can be a relatively ideal control measure.

Abstract
The quality of the recipient cytoplasm was reported as a crucial factor in maintaining the vitality of SCNT embryos and SCNT efficiency for dairy cows. Compared with oocytes matured in vivo, oocytes matured in vitro showed abnormal accumulation and metabolism of cytoplasmic lipids. L-carnitine treatment was found to control fatty acid transport into the mitochondrial β-oxidation pathway, which improved the process of lipid metabolism. The results of this study show that 0.5 mg/ml L-carnitine significantly reduced the cytoplasmic lipid content relative to control. No significant difference was observed in the rate of oocyte nuclear maturation, but the in vitro developmental competence of SCNT embryos was improved in terms of increased blastocyst production and lower apoptotic index in the L-carnitine treatment group. In addition, the pregnancy rate with SCNT embryos in the treatment group was significantly higher than in the control group. In conclusion, the present study demonstrated that adding L-carnitine to the maturation culture medium could improve the developmental competence of SCNT embryos both in vitro and in vivo by reducing the lipid content of the recipient cytoplasm.

Abstract
High-intensity focused ultrasound (HIFU) has emerged as a promising uterus-sparing and possibly fertility-sparing treatment modality for women with adenomyosis, especially those who desire to conceive. We conducted this systematic review and performed a meta-analysis on clinical studies aimed to improve reproduction in women with adenomyosis. After extensive search of PubMed and CNKI, we identified 10 studies published in English and Chinese involving a total of 557 patients with adenomyosis who desired to conceive after HIFU treatment. We found a pooled estimate of pregnancy rate of 53.4% and of the live birth rate of 35.2%, and there was a substantial heterogeneity among these studies. While there is a potential for HIFU treatment to improve fertility for patients with adenomyosis who desired to conceive, such evidence is very weak as of now. Comparative studies with much higher methodological rigor, preferably randomized clinical trials, are badly needed to further illuminate this issue.

Abstract
PURPOSE The proportion of patients with poor ovarian response (POR) is increasing, but effective treatment remains a challenge. To control the hidden peaks of luteinizing hormone (LH) and premature ovulation for poor responders, this study investigated the efficacy of flexible short protocol (FSP) with gonadotropin-releasing hormone antagonist (GnRH-ant) on trigger day. METHODS The 662 cycles of POR patients were retrospectively analyzed. The cohort was divided into control and intervention groups. The intervention group (group A) with 169 cycles received a GnRH-ant given on trigger day. The control (group B) with 493 cycles received only FSP. The clinical outcomes of the two groups were compared. RESULTS Compared with group B, with gonadotropin-releasing hormone antagonist (GnRH-ant) on trigger day in group A the incidences of spontaneous premature ovulation decreased significantly (2.37% vs. 8.72%, P < 0.05). The number of fresh embryo-transfer cycles was 45 in group A and 117 in group B. There were no significant differences in clinical outcomes, including implantation rate, clinical pregnancy rate, live birth rate and the cumulative live birth rate (12.0% vs. 9.34%; 22.22% vs. 21.93%; 17.78% vs. 14.91%; 20.51% vs. 20%, respectively; P > 0.05) between the two group. CONCLUSION FSP with GnRH-ant addition on trigger day had no effect on clinical outcomes, but could effectively inhibit the hidden peaks of luteinizing hormone (LH) and spontaneous premature ovulation in POR. Therefore, it is an advantageous option for POR women.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Infertility is a global public health issue related to gynecological diseases and psychological disorders such as stress, depression, and fatigue. Prescriptions of various herbs in traditional East Asian medicine (TEAM) have recently gained attention among patients as a complementary alternative therapy for female infertility. However, studies on systemic analysis of the use of herbal medicines according to TEAM patterns or the therapeutic effects of herbal medicines on female infertility are limited. AIM OF THE STUDY We aimed to systematically investigate the single herb and TEAM patterns that are commonly used for treating female infertility using network analysis. Additionally, we performed a meta-analysis to assess the effect of herbal medicine on the pregnancy rate in women with infertility. MATERIALS AND METHODS PubMed, EMBASE, Korean Studies Information Service System, Science ON, Research Information Sharing Service, and Oriental Medicine Advanced Searching Integrated System were searched for randomized controlled trials (RCTs) reporting the pregnancy rate of herbal medicine for infertility until July 2021. Following identifying the top three herbs used in treating female infertility, a network analysis was performed to reveal the TEAM pattern relationships between each herb. A meta-analysis was performed to evaluate the therapeutic effect of herbal medicine on pregnancy rate. Moreover, the methodological quality of RCTs was analyzed using Consolidated Standards of Reporting Trials (CONSORT) extension guidelines and the Risk of bias (RoB) tool. RESULTS Eighteen RCTs with 2,662 participants were included. Cuscuta chinensis Lam. (Tusizi) is the most commonly used herb for treating female infertility, followed by Angelica gigas Nakai (Danggui) and Cyperus rotundus L. (Xiangfuzi). These herbs were mainly used to treat patients with kidney deficiency or kidney deficiency combined with blood stasis or Phlegm-dampness on the TEAM pattern. The meta-analysis revealed that the effect of herbal medicine led to a significant increase in pregnancy rates compared to the placebo treatment. Adverse events in the included studies were generally mild and infrequent. The methodological quality of RCTs using CONSORT extension was poor, while the RoB of the included RCTs was generally low. CONCLUSIONS The findings of this review suggest that herbal medicine will be beneficial for treating female infertility by improving pregnancy rates. However, more carefully designed studies on herbal medicines are encouraged to improve the quality of herbal medicine research in the future.

Abstract
BACKGROUND Endometriosis is commonly observed in infertile women and can be staged with regard to severity [e.g. according to the American Fertility Society (AFS) classification]. This condition can cause infertility through impaired oocyte quality, fertilization disorders, tubal lesions, adhesions, deep infiltration, and adenomyosis. Although women with endometriosis often turn to in vitro fertilization (IVF) programs, the literature data on IVF outcomes are sometimes contradictory (i.e. the same as in other etiologies of infertility, or worse). The objective of the present study was to assess and compare pregnancy rates in women with and without endometriosis and according to the endometriosis stage. METHODS We retrospectively studied clinical and ongoing pregnancy rates in IVF and the cumulative pregnancy rates after frozen/thawed embryo transfers, in women without endometriosis (group A) or with endometriosis (group B). We further compared groups in which endometriosis was staged according to the revised AFS classification: stage 1/2 (group C), stage 3/4 (group D, without endometrioma), and endometrioma alone (group E). RESULTS We documented 430 cycles in group A and 460 in group B (including 56 in group C, 88 in group D and 316 in group E). After fresh or frozen/thawed embryo transfers, the differences in ongoing pregnancy rates between groups A and B were not significant. However the cumulative rates per couple were significantly lower (p < 0.05) in group D. CONCLUSIONS We recommend IVF for women with endometriosis because the pregnancy rates are similar to those observed for women with other types of infertility. This approach is in line with the international guidelines issued by assisted reproductive technology societies. These results again raise the question of whether surgical resection of deep infiltrating endometriosis (stage 3/4) should be recommended before admission to an IVF program. Trial registration This study was approved by an institutional review board (CPP Ouest VI, Brest, France): reference: B2020CE.43.

Abstract
Laser-assisted hatching (LAH) is a widely used and unavoidable technique in assisted reproductive technology after frozen embryo transfer (FET). We aimed to investigate the safety and efficacy of completely ZP (zona pellucida) removed by an assisted laser group compared to an intact group after FET. This retrospective study involved 320 SVBT single vitrified-warmed blastocyst transfers of 213 patients who underwent clomiphene citrate (CC) based minimal stimulation protocol. This study compared 160 SVBT with ZP that were completely removed using laser-assisted (laser beams of 10-15, a wavelength of 1.48 μm, and duration of 1.8-2.2 ms) to 160 cases of intact SVBT. Fisher's exact test, chi-squared test, and logistic regression are used for statistical analysis. The women's age, cause of infertility, BMI, transferred embryo day, insemination methods, and blastocyst grade were not significantly different between two groups. The implantation rate (66.2% vs. 51.2%, P < 0.01), the clinical pregnancy rate (CPR, 52.5% vs. 39.3%, P = 0.01), and the live birth rate (LBR, 43.7% vs. 29.3%, P < 0.01) were significantly higher in the completely ZP removed than the intact group. In logistic regression analysis, the laser-assisted hatching group showed about 2 times higher implantation rate and CPR and LBR than the control group. But miscarriage, gestational weeks, gender, birth weight, and twin births were insignificant between two groups. Our study suggests ZP free embryo transfer by assisted laser is more effective and safer than intact embryo transfer.

Abstract
OBJECTIVE To compare letrozole in combination with gonadotropins versus letrozole monotherapy in ovulation induction and clinical pregnancy among infertile women with polycystic ovarian syndrome (PCOS). METHODS Several databases were searched for available clinical trials from inception until March 2023. We selected randomized controlled trials (RCTs) that compared sequential letrozole/gonadotropin versus letrozole alone among infertile women who met the Rotterdam criteria for PCOS. RevMan software was used to perform our meta-analysis. Our primary outcomes were ovulation and clinical pregnancy rates. Our secondary outcomes were endometrial thickness, number of mature follicles (diameter ≥ 18 mm), and incidence of miscarriage and ovarian hyperstimulation syndrome (OHSS). RESULTS Six RCTs were retrieved with a total number of 723 patients. The ovulation and clinical pregnancy rates were significantly higher among the letrozole/gonadotropin group versus the letrozole monotherapy group (p < 0.001). In addition, there were significant improvements in endometrial thickness and number of mature follicles in the letrozole/gonadotropin group. There were no significant differences between the two groups regarding incidence of miscarriage and ovarian hyperstimulation syndrome. CONCLUSION Letrozole in combination with gonadotropin is superior to letrozole alone in improving ovulation induction and clinical pregnancy among PCOS patients. More trials are required to confirm our findings.

Abstract
Objective This retrospective study aimed to investigate the prevalence of chronic endometritis, diagnosed using CD138 immunohistochemistry, among infertile women and to assess the association between chronic endometritis and recurrent implantation failure (RIF). Methods In total, 266 patients who underwent hysteroscopy due to infertility between 2019 and 2020 were included in the analysis. Of these, 136 patients with RIF and 130 non-RIF patients were included in the study. CD138 immunohistochemistry test results, blood biomarkers (including natural killer cells, white blood cells, and the lymphocyte-to-neutrophil ratio), and data on pregnancy outcomes were obtained. If the CD138 test yielded a positive result, the patients received antibiotic treatment. Results The overall proportion of CD138-positive patients was 32.7% (87/266). The CD138 positivity rate was not related to the number of cycles with implantation failure. In the RIF patient group, no significant associations were found between CD138 positivity and peripheral blood markers. The clinical pregnancy rates were similar between infertile women treated with antibiotics for chronic endometritis and those without chronic endometritis. Conclusion To improve the pregnancy rate in infertile patients, it may be helpful to combine CD138 testing with other laboratory tests and administer antibiotic treatment if the result is positive.

Abstract
BACKGROUND Information on reproduction of harvested species such as mule deer (Odocoileus hemionus) is vital for conservation and management. Furthermore, parturition in ungulates may be detected using patterns of movement logged by GPS transmitters. Several movement-based methods have been developed to detect parturition in ungulates including the Peterson method, behavioral change point analysis (BCPA), rolling minimum convex polygons (rMCP), individual-based method (IBM), and population-based method (PBM). Our objectives were to (1) test the accuracy and the precision of each previously described method and (2) develop an improved method optimized for mule deer that incorporated aspects of the other methods. METHODS We determined parturition timing and status for female mule deer fitted with GPS collars and implanted with vaginal implant transmitters (VITs). We used movement patterns before and after parturition to set movement thresholds for each movement-based method. Following model training, we used location and birth date data from an external dataset to test the effectiveness of each movement-based method. Additionally, we developed a novel method for detecting parturition called the analysis of parturition indicators (API). We used two regression analyses to determine the accuracy and precision of estimates generated by each method. RESULTS The six methods we employed varied in accuracy, with the API, rMCP, and BCPA being most accurate. Precision also varied among methods, with the API, rMCP, and PBM generating the most precise estimates of parturition dates. The API and the rMCP performed similarly and better overall than any of the other existing methods. CONCLUSIONS We found that movement-based methods could be used to accurately and precisely detect parturition in mule deer. Further, we determined that the API and rMCP methods had the greatest overall success at detecting parturition in mule deer. The relative success of the API and rMCP may be attributed to the fact that both methods use home range size to detect parturition and are validated using known parturition dates of collared deer. We present the API as an efficient method of estimating birth status and timing of parturition of mule deer fitted with GPS transmitters, as well as affirm the effectiveness of a previously developed method, rMCP.

Abstract
BACKGROUND The Republic of Georgia implemented COVID-19-related restrictions starting on 31 March 2020, when it imposed a 1-month strict lockdown, after which the country continued with some form of restrictions for 1 year. These restrictions created barriers to healthcare access, affected healthcare services, caused severe economic degradation, and changed reproductive behavior. The aim of this study was to explore the impact of COVID-19-related restrictions on pregnancy and abortion rates in Georgia. METHODS Information on pregnancy, abortion, and related variables was extracted from the Georgian Birth Registry from January 2018 through April 2022. The final study sample included 232,594 pregnancies and 86,729 abortions. We used interrupted time series analysis to study the impact of COVID-19-related restrictions. RESULTS There were slightly decreasing trends in pregnancy and abortion rates in the pre-pandemic period (1 January 2018-31 March 2020). During the 1-month strict lockdown (1 April-30 April 2020), pregnancy and abortion rates decreased in all investigated age groups. There were no substantial differences in pregnancy or abortion rates in the pandemic period (for pregnancies: 1 April 2020-30 June 2021; for abortions: 1 April 2020-30 April 2022) compared to the pre-pandemic period. The precision of all estimates suggested that both small increases and decreases in pregnancy and abortion rates are reasonably compatible with our data. CONCLUSIONS Despite the 1-year-long COVID-19-related restrictions, our results did not indicate substantial long-term changes in pregnancy or abortion rates during the study period for any age group. This may indicate that the restrictions did not substantially influence access to contraception, abortion services, or reproductive behavior.

Abstract
PURPOSE This study aimed to analyze the efficacy of psychosocial interventions for improving pregnancy rates in infertile women undergoing in vitro fertilization (IVF) treatment through a systematic review and meta-analysis. METHODS Twelve studies were included in the meta-analysis. To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3. The possibility of publication bias was evaluated using funnel plots and Egger's method. RESULTS A statistically significant effect size (standardized mean difference [SMD] = 1.39; 95% confidence interval [CI] = 1.11-1.71; p = 0.004; I2 = 19%) was found for the 12 studies that investigated the effects of psychosocial interventions on clinical pregnancy rates. The psychosocial interventions that had a significant effect on pregnancy rates were mind-body interventions (SMD = 1.37; 95% CI = 1.01-1.85; p = 0.040; I2 = 0%) and cognitive behavioral therapy (SMD = 2.19; 95% CI = 1.17-4.13; p = 0.010). CONCLUSIONS The results suggest that psychosocial interventions affect pregnancy rates. Moreover, they indicate that mind-body interventions and cognitive behavioral therapy are beneficial for improving the pregnancy outcome in infertile women undergoing IVF.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in women of childbearing age. Randomized controlled trials (RCTs) have reported that exenatide and metformin are effective in the treatment of PCOS. In this meta-analysis, we aimed to compare the effectiveness and safety of exenatide alone or in combination with metformin versus metformin in patients suffering from PCOS. METHODS RCTs of exenatide therapy were identified through a search of electronic databases in November 2022 and updated in October 2023. Eligible studies were identified independently by the reviewers. Outcomes were analysed with Revman 5.4. RESULTS Nine RCTs among 214 studies on 1059 women with PCOS were included in the analysis, and among the nine RCTs, eight studies compared exenatide with metformin. Our meta-analysis demonstrated that exenatide was more effective than metformin in terms of pregnancy rate (RR 1.85 [95% CI 1.19,2.86] P = 0.006), sex hormone-binding globulin (SHBG) (MD 5 [95% CI 3.82,6.18] P < 0.001), and follicle-stimulating hormone (FSH) (MD 0.82 [95% 0.41,1.24] P < 0.001). The reductions in total testosterone (TT) (SMD -0.43 [95% CI -0.84, -0.03] P = 0.04) was more significant after treatment with exenatide than after treatment with metformin. In terms of safety, exenatide had a lower diarrhea rate (RR 0.11 [95% CI 0.01, 0.84]) than metformin. In the other three studies, exenatide plus metformin was compared with metformin. Exenatide combined with metformin was more effective in improving SHBG (MD 10.38[95%CI 6.7,14.06] P < 0.001), Matsuda index (MD 0.21[95%CI 0.05,0.37]) and reducing free androgen index (FAI) (MD -3.34 [-4.84, -1.83] P < 0.001), Weight (MD -2.32 [95%CI -3.89, -0.66]) and WC (MD-5.61[95%CI -8.4, -2.82] P < 0.001). The incidence of side effects between exenatide plus metformin and metformin was not statistically significant. CONCLUSIONS Exenatide alone or in combination with metformin is more effective than metformin for women with PCOS. Considering the evidence on effectiveness and safety, exenatide alone or in combination with metformin may be a better treatment approach than metformin for women with PCOS.

Abstract
PURPOSE This study was aimed to assess the effectiveness of Glucagon-like peptide 1 receptor agonists on pregnancy rate, menses, anthropometric and hormonal parameters in PCOS patients. METHODS We conducted searches of the published literature in PubMed, EMBASE, Cochrane Library, Web of Science up to September 2022. Data from randomized controlled trials were obtained to assess the effects of GLP1RAs in PCOS women. Weighted mean difference, standardized mean difference, and risks ratio were employed for effect size estimation using a random-effects model. RESULTS A total of 840 patients with 469 individuals in GLP1RAs group and 371 individuals in control group from 11 RCTs were included. GLP1RAs usage was associated with an improvement in natural pregnancy rate (RR: 1.72, 95% CI 1.22 to 2.43, P = 0.002, I2 = 0%) and menstrual regularity (SMD: 1.72, 95% CI 0.60 to 2.85, P < 0.001, I2 = 95.6%). There were no statistically significant differences in total pregnancy rate, IVF pregnancy rate between two groups, but total PR elevated in a short time after GLP1RAs as shown in subgroup analysis. Randomization to GLP1RAs treatment was associated with great improvement in HOMA-IR, BMI, WC, SHBG and a slight reduction in TT compared to control group. A decrease in TBF was seen in European population. GLP1RAs monotherapy was not superior to metformin when it came to fT, DHEAS, FAI. CONCLUSIONS Prescription of GLP1RAs improves natural pregnancy rate, menstrual cyclicity and insulin sensitivity, anthropometrics, hormonal indexes in PCOS women.

Abstract
Establishing methods for evaluating genomic estimated breeding values of bovine embryos can potentially increase the efficiency of breeding programs by transferring only embryos with a high genomic estimated breeding value. This may be achieved by analyzing DNA from trophectoderm biopsies. However, manipulation of bovine embryos is associated with a risk of impaired conceptus health. More knowledge on the health implications of embryonic handling procedures is required. In this study, we followed pregnancies after transfer of in vitro-produced (IVP) embryos and assessed the health of the offspring during the first 2 weeks of life. Three groups of calves were studied: i) freshly transferred non-biopsied embryos (39 transfers, 17 calves; Group B-/C-); ii) biopsied and freshly transferred IVP embryos (42 transfers, 21 calves; Group B+/C-); iii) biopsied and cryopreserved IVP embryos (17 transfers, 6 calves; Group B+/C+). Blood biochemical and hematologic values were compared between groups and to a control group of 13 calves produced by conventional artificial insemination. The pregnancy rate on day 50 and the calving rate did not differ among the groups, but the average gestation length of the B+/C+ group was significantly shorter and with wider variation than the two other groups. There was a tendency toward a higher average body weight at birth in group B+/C+ (45.1 kg) and the standard deviation in body weight was larger (11.7 kg) compared to the B-/C- (39.5 kg; 3.2 kg) and B+/C- (41.8 kg; 6 kg) groups. Body weight on day 14 was higher in the B+/C+ calves compared to the other groups. There was no difference in the biochemical and hematological values at birth between the groups and these were within the normal range. However, when compared to a group of calves produced by standard artificial insemination, significantly higher concentrations were found for the hepatic-related enzymes ALAT, ASAT, ALP, and GGT in group B-/C-and B+/C-, while only higher ALP concentrations were found in B+/C+ calves. The biochemical findings indicate higher heterogeneity in IVP calves compared to calves produced by artificial insemination. The more manipulated IVP embryos also showed increased heterogeneity in body weight at birth, with a shift toward heavier calves, which calls for closer attendance at parturition to handle dystocia in a timely manner and minimize fetal losses.

Abstract
This experiment was designed to evaluate the effects of increasing doses of estradiol cypionate (ECP) and different body condition score (BCS) on reproductive performance of Bos indicus beef females assigned to a timed-artificial insemination (TAI) management. In this experiment, 1683 Bos indicus Nellore cows were blocked by parity and assigned to receive 1) an intravaginal P4 device (1.9 g of P4) and 2.0 mg of estradiol benzoate on day -11, 12.5 mg (i.m.) of dinoprost tromethamine, 300 IU (i.m.) of equine chorionic gonadotrophin, 0.6 mg (i.m.) of estradiol cypionate and CIDR withdrawal on day -2, followed by TAI on day 0 (n = 849; 0.6ECP) or 2) the same synchronization protocol with 1.0 mg of ECP on day -2 (n = 834; 1.0ECP). In both treatments, estrus expression was measured between days -2 and 0. Body condition score (BCS) was evaluated on days -11, 31, and 71 of the experiment and the BCS variation (Δ) was also determined between these timepoints. Transrectal ultrasonography was performed on days 31, 71, and 111 for pregnancy rate determination. All binary data were analyzed using cow as the experimental unit with GLIMMIX, whereas continuous variables were analyzed with the MIXED procedure of SAS. No treatment effects were observed on estrus expression rate. Treatment × BCS interactions were observed for pregnancy rates in all time points (days 31, 71, and 111), as 1.0ECP cows with a LOW BCS also had a greater P/AI than cows assigned to 0.6ECP. In summary, increasing the dose of ECP benefited the reproductive performance of Nellore beef cows with a reduced BCS (≤2.75), whereas no benefits were seen when the BCS was considered adequate (>2.75).

Abstract
Background The purpose of the study was to assess whether the coadministration of 150 IU of recombinant LH instead of 75 IU in women aged 35-39 improves the results in agonist ICSI cycles stimulated with 300 IU of recombinant FSH. Methods In this study, two ovarian stimulation protocols coexisted which were identical except in the administered dose of recombinant LH, for which some patients received 150 IU (n=231) and some received 75 IU (n=216). Both groups received 300 IU of recombinant FSH. Gonadotropins were reimbursed by the National Health System. Statistical analysis was performed by Student's t test, χ2, and ANCOVA. Significance level was established at p=0.05. Results The number of retrieved oocytes was slightly higher in the 300/150 group (9.06±5.53 vs. 8.61±5.11), but the differences were not significant. Results were similar with the number of metaphase II oocytes (7.18±4.86 vs. 6.72±4.72) and the number of fertilized oocytes (4.64±3.2 vs. 4.23±2.72). The per-transfer clinical pregnancy rates exhibited close similarity between both groups (32.84% vs. 32.46%), as did the per-transfer live birth rates (29.90% vs. 30.37%) and the implantation rate. The rate of hyperstimulation syndrome (OHSS) as well as the rate of cancellation due to OHHS risk was similar in both groups. There was also no difference in the miscarriage rate. When results were expressed by per started cycle or by oocyte pick-up, the results remained very similar in both groups. Conclusion In women aged 35-39 undergoing ovarian stimulation with recombinant FSH in agonist cycles, the coadministration of 75 or 150 UI of recombinant LH did not influence pregnancy rates. However, a slight increase in the number of retrieved oocytes should not be disregarded.

Abstract
OBJECTIVE To observe the effect of acupuncture combined with medication on the pregnancy outcome of kidney deficiency and blood stasis type recurrent implantation failure (RIF) in prethrombotic infertility patients. METHODS A total of 70 RIF patients of kidney deficiency and blood stasis type who were to undergo freeze-thaw embryo transplantation were randomly divided into control and treatment groups, with 35 cases in each group. Patients in the control group were given the basic treatment of artificial periodic freeze-thaw embryo transfer and oral aspirin enteric-coated tablet, 25 mg each time, twice a day, for 3 consecutive menstrual cycles. Patients in the treatment group were treated with acupuncture on the basis of the control group, 30 min each time, 3 times a week, for 3 consecutive menstrual cycles. The clinical pregnancy rate, embryo implantation rate and live birth rate of the two groups were compared. Before treatment and 1 day before transplantation, the scores of kidney deficiency and blood stasis symptom were compared. The blood flow pulse index (PI) and resistance index (RI) of the uterus spiral artery were detected by Doppler ultrasound before treatment and 1 day before transplantation. The endometrial thickness was detected 1 day before transplantation. The contents of plasma D-dimer, serum homocysteine (Hcy) and serum thromboxane B2 (TXB2) were detected. RESULTS The clinical pregnancy rate, embryo implantation rate and live birth rate in the treatment group were higher than those in the control group (P<0.05). After treatment, the scores of kidney deficiency and blood stasis symptom, the levels of plasma D-dimer, serum Hcy and TXB2, the PI and RI value in both groups were decreased (P<0.05) compared with those before treatment, and the indexes in the treatment group were decreased (P<0.05) more than those in the control group. There was no significant difference in endometrial thickness between the two groups. In the course of treatments, 7 patients in the control group underwent gastric distension pain, poor appetite, constipation, nausea and other gastrointestinal reactions, while only 2 patients in the treatment group had the above discomfort reactions. CONCLUSION On the basis of medication, acupuncture can reduce the serum TXB2 content in RIF patients in prethrombotic state, improve vascular endothelial function, enhance endometrial tolerance, alleviate the symptoms of kidney deficiency and blood stasis, reduce drug adverse reactions, and ultimately improve the pregnancy outcome and increase the rate of embryo implantation.

Abstract
BACKGROUND Fertility-sparing treatments (FSTs) have played a crucial role in the management of early-stage cervical cancer (ECC); however, there is currently no standard of care for women with ECC ≥ 2 cm who wish to preserve their fertility. The current orientation of the scientific community comprises upfront surgical techniques and neoadjuvant chemotherapy (NACT) followed by minor surgery such us conization. However these approaches are not standardized. This systematic review aimed to collect the evidence in the literature regarding the obstetric outcomes of the different techniques for applying FSTs in ECC ≥ 2 cm. METHODS A systematic review was performed in September 2022 using the Pubmed and Scopus databases, from the date of the first publication. We included all studies containing data regarding pregnancy, birth, and preterm rates. RESULTS Fifteen studies fulfilled the inclusion criteria, and 352 patients were analyzed regarding fertility outcomes. Surgery-based FST showed the pregnancy rate (22%), birth rate (11%), and preterm rate (10%). Papers regarding FST using the NACT approach showed a pregnancy rate of 44%, with a birth rate of 45% in patients who managed to get pregnant. The preterm rate amounted to 44%, and pregnancy rates and birth rates were significantly different between the two groups (p < 0.001). CONCLUSION Fertility preservation in patients with ECC > 2 cm is challenging. The endpoint for evaluating the best treatment should include oncological and fertility outcomes together. From this prospective, NACT followed by less radical surgery could be a reasonable compromise.

Abstract
PURPOSE Hyaluronan-enriched transfer medium (HETM) could improve the clinical pregnancy rate (CPR) for patients with repeated implantation failures (RIF). In contrast, there have been seldom reports addressing the potentially beneficial effects of HETM for morphologically poor blastocysts (MPBLs). Our study aimed to evaluate whether the use of HETM would improve the CPR for the patients who were transferred with euploid MPBLs. METHODS Patients who underwent single euploid blastocyst transfer between July 2020 and June 2022 were enrolled. We included only those blastocysts confirmed as euploid by PGT-A, and those blastocysts were transferred after thawing. The natural ovulatory cycle or hormone replacement cycle (HRC) protocol were used for endometrial preparation for frozen embryo transfer (FET). A total of 1,168 FET cycles were performed in the study period, including 954 cycles of morphologically good blastocysts (≥ 4BB in Gardner's classification), and 85 cycles of MPBLs, of which 47 were transferred using HETM in FET (the HETM group), and the remaining 38 were transferred with the medium without hyaluronan (the control group). We compared the CPR between these two groups. RESULTS The characteristics of patients were similar between the HETM and control groups. The CPR in the HETM group was significantly higher than the control group (47.4% and 21.5%, respectively, p = 0.019). The multiple logistic regression analysis found that the use of HETM was a predictive factor of positive pregnancy outcomes (OR = 5.08, 95% CI = 1.62-16.0, p = 0.019). CONCLUSION Our data suggests that HETM used in the euploid blastocyst transfer can improve the clinical pregnancy rates of morphologically poor blastocysts.

Abstract
This study aimed to assess the effects of embryonic developmental stage, quality grade, and fresh or frozen/thawed conditions on the pregnancy rate and sex ratio of live offspring in Hanwoo (Bos taurus coreanae) cows. The quality and developmental stage of in vivo-derived (IVD) transferred embryos were evaluated using the standard criteria of the International Embryo Technology Society. The recipient cows were synchronized using conventional (estradiol benzoate and progesterone) protocols before embryo transfer. Embryos were transferred to 297 cows, and pregnancy was monitored for 60-70 days after embryo transfer. The pregnancy rates of fresh and frozen/thawed embryos were 56.90% and 52.49%, respectively. Pregnancy rates varied according to embryo quality (56.18% for grade 1 vs. 36.67% for grade 2). Pregnancy rates also varied by developmental stage and cryopreservation (67.86% vs. 63.49% for stage 4-1, 64.00% vs. 54.72% for 5-1, and 50.00% vs. 47.83% for 6-1, in fresh embryos vs. frozen/thawed embryos, respectively). For stage 7-1, the pregnancy rates were 72.73% for fresh embryos and 20.00% for frozen/thawed embryos. In 66 fresh embryos, the sex ratio of live offspring was 5:5, whereas it was 4(female):6(male) for frozen/thawed embryos among the 95 frozen/thawed embryos. The miscarriage rate was approximately 3% higher for frozen/thawed embryos than for fresh embryos (18.1% for fresh vs. 21.1% for frozen). Seasonal fertility rates were 33.3% in spring, 55.67% in summer, 52.8% in autumn, 60.0% in winter. The following male-to-female ratios were observed in different seasons: 6.7:3.3 in spring, 4.0:6.0 in summer, 5.5:4.5 in autumn, and 3.3:6.7 in winter. The current data revealed no significant differences in pregnancy rates between fresh and frozen/thawed IVD embryos. However, there was a lower pregnancy rate with advanced-stage frozen/thawed embryos (stage 7-1). The current study provides comprehensive results for the better optimization of embryo transfer in Hanwoo cattle to obtain the desired fertility rate, pregnancy rate, and sex ratio of calves. These results provide important insights into the factors that influence the viability and success of IVD embryo transfer in Hanwoo cows and may have practical applications for improving breeding programs and reducing production costs.

Abstract
Few researches have examined the impact of air pollution exposure during various time windows on clinical outcomes in women receiving in vitro fertilization (IVF) therapy, and the findings of studies have been conflicting. We investigated the effects of six air pollutants exposure during different time windows (period 1, 85 days before egg retrieval to the beginning of gonadotropin; period 2, the beginning of gonadotropin to egg collection; period 3, egg collection to embryo transfer; period 4, embryo transfer to serum hCG measurement; period 5, serum hCG measurement to transvaginal ultrasonography; period 6, 85 days before egg retrieval to hCG measurement; period 7, 85 days before egg retrieval to transvaginal ultrasonography) on clinical outcomes of IVF therapy. A total of seven databases were searched. NO2 (period 6), SO2 (period 2, 3, and 7), CO (period 1, 2 and 7) exposure were linked to lower likelihoods of clinical pregnancy. PM2.5 (period 1), PM10 (period 1), SO2 (period 1, 2, 3, 4, and 6), NO2 (period 1) were linked to lower likelihoods of biochemical pregnancy. PM2.5 (period 1), SO2 (period 2 and 4) and CO (period 2) were linked to reduced probabilities of live birth. Our results implied that period 1 might be the most sensitive exposure window. Air pollution exposure is linked to reduced probabilities of clinical pregnancy, biochemical pregnancy, and live birth. Therefore, preventive measures to limit air pollution exposure should be started at least three months in advance of IVF therapy to improve pregnancy outcomes.

Abstract
A longitudinal observational study was carried out from January 2020 to July 2021 to assess the impact of subclinical mastitis (SCM) on reproductive performance and its association with uterine health of crossbred dairy cows. The California Mastitis Test (CMT) and cytobrush technique were used to screen subclinical mastitis and subclinical endometritis, respectively. Milk samples positive for subclinical mastitis were subjected to bacteriological analysis. Data from 84 clinically healthy cows collected and analyzed. The present study revealed a prevalence of subclinical mastitis of 51.2% (43 of 84). The mean days from calving to first service interval were significantly longer in subclinical mastitis positive cows than negative (control) cows (120.51 ± 24.5 and 85.15 ± 28.3, respectively) (P < 0.05). The mean number of services per conception was significantly higher in positive cows (2.51 ± 0.83) than in negative cows (1.59 ± 0.81) (P < 0.05). Lower conception and pregnancy rates at first services were observed in subclinical mastitis cows. Risk factors analysis revealed that prevalence of subclinical mastitis significantly differed with the parity and body condition score (P < 0.05). The current study revealed that subclinical mastitis was significantly and directly associated with subclinical endometritis (P < 0.05). Subclinical mastitis significantly decreased (P = 0.000) progesterone concentrations and increased (P = 0.001) the cortisol concentrations. Staphylococcus aureus were the most predominant bacterial isolates from subclinical mastitic milk, followed by coagulase negative staphylococci (CNS) and streptococci. This study concludes a high prevalence of subclinical mastitis caused by Staphylococcus aureus could inflict harmful effects on reproductive performance of dairy cows, emphasizing the relevance of mastitis control programs in dairy farms.

Abstract
Estrus synchronization is necessary for intensive donkey farming. Studies on estrus synchronization in jennies are, however, scarce. We aimed to investigate the susceptibility of the donkey corpus luteum to cloprostenol and design a successful estrus synchronization protocol. Firstly, the effects of different cloprostenol doses and the timing effect of cloprostenol treatment on estrous cycle was investigated. The time from treatment to luteolysis, the ovulation interval, pre-ovulatory diameter, and ovulation rates were compared between groups. Secondly, to identify the best protocol, eight estrus synchronization protocols from three categories were examined. In the first category, jennies in groups A (n = 55) and B (n = 30) received a progesterone releasing intra-vaginal device (JVID®) and cloprostenol treatment. In the second category (group C to F), jennies were pretreated with deslorelin, and then treated with JVID and cloprostenol, including groups C (n = 50), D (n = 50), E (n = 70), and F (n = 65). In the third category, jennies were treated with deslorelin and cloprostenol, including groups G (n = 40) and H (n = 40). Comparisons were made among groups regarding the degree of synchronization, ovulation, and pregnancy rates. Treatment with 0.4 mg cloprostenol on the third day following ovulation minimized the length of the luteal phase and estrous cycle. Synchronization rate varied from 60.0% to 88.6% among groups and was highest in group E. Pregnancy rates did not differ among the eight protocols. In conclusion, cloprostenol effectively induced luteolysis in jennies and a treatment protocol combining deslorelin, cloprostenol, and JVID is efficient for estrus synchronization in donkeys.

Abstract
This study looked at the effectiveness and financial benefits of treating repeat breeder (RB) dairy cows with the GnRH agonist gonadorelin 7 to 14 days after artificial insemination (AI). One hundred and eighty-eight healthy dairy cows (2.4 ± 1.3 lactations) with average milk yield of 42.1 ± 6.8 kg milk/day, at 179 ± 38.4 days in milk with 3.8 ± 1 artificial inseminations were divided into two groups, experimental (E group, n = 98) and control (C group, n = 90). The GnRH agonist gonadorelin was given 7 - 14 days after AI to the E group to evaluate the embryo survival in RB cows. The control group did not receive any treatment. Recorded pregnancy rates and cumulative pregnancy rates were superior in the E group (49% and 64.3%) compared with the C group (37.8% and 55.5%). The interaction between therapy and repeat breeder had a significant impact on the pregnancy rate and accessory corpus luteum (CL), according to a binary logistic regression study. The UW-DairyRepro$ decision support tool utilized in this experiment demonstrated that by implementing this approach, the net present value can be increased by US dolars (US$)30.2/RB cow/year. Thus, the single therapy with GnRH agonist gonadorelin between 7 - 14 days after artificial insemination enhanced the potential for a second CL in repeat-breeder pregnant cows, presumably favoring embryo survival.

Abstract
PURPOSE To compare pregnancy rates in GnRH-antagonist cycles triggered with hCG after luteal phase support with intranasal GnRH-agonist as sole luteal phase support versus standard vaginal progesterone preparation. METHODS Prospective randomized controlled study of patients who underwent antagonist-based IVF cycles triggered with hCG at university-affiliated tertiary medical center between 2020 and 2022. Patients meeting the inclusion criteria were randomly assigned to either intranasal GnRH-agonist or vaginal progesterone for luteal phase support. Pregnancy rates were the main outcome compared between the two study groups. RESULTS A total of 150 patients underwent 164 cycles, 127 cycles of which were included in the study cohort. Of them, 64 (50.4%) and 63 (49.6%) cycles were treated with GnRH-agonist or progesterone, respectively, as sole luteal phase support. A significantly higher pregnancy rate was demonstrated in the GnRH-agonist group compared with the progesterone group. After adjustment of several potential confounders such as age, body mass index, past obstetric history, number of IVF cycles, oocyte retrieved and embryos transferred, GnRH-agonist was still associated with a higher pregnancy rate (odds ratio 3.4, 95% confidence interval 1.4-8.3). Ovarian hyperstimulation syndrome rates were similar between the groups. CONCLUSIONS This prospective study suggests that nasal GnRH-agonist for luteal phase support is associated with higher pregnancy rates compared with standard progesterone support in an antagonist-based protocol triggered with hCG, while maintaining a similar safety profile.

Abstract
RESEARCH QUESTION Does antioestrogen effect of clomiphene citrate (CC) on the endometrium reduce implantation and thereby decrease pregnancy and live birth rate per transferred embryo? METHODS In this cohort, unstimulated IVF cycles modified with clomiphene citrate (CC-NC-IVF) and unstimulated, natural IVF cycles (NC-IVF) conducted between 2011 and 2016 were included. CC was applied in a dosage of 25mcg per day, starting on cycle day 7 until ovulation trigger day. Primary outcomes were clinical pregnancy rate, defined as amniotic sac visible in ultrasound, and live birth rate per transferred embryo. Miscarriage rate calculated as amniotic sac not ending in a live birth was secondary outcome. A modified mixed-effect Poisson regression model was applied, and adjustments were made for female age, parity, type and cause of infertility. Additionally, stratification by parity and age was performed. RESULTS Four hundred and ninety-nine couples underwent a total of 1042 IVF cycles, 453 being NC-IVF and 589 being CC-NC-IVF cycles. Baseline characteristics of both groups did not differ. Addition of CC did neither decrease clinical pregnancy rate (aRR 0.86; 95% CI 0.67-1.12) nor live birth rate per transferred embryo (aRR 0.84; 95% CI 0.62-1.13) in comparison with NC-IVF. Miscarriage rate did not differ between CC-NC-IVF and NC-IVF (aRR 0.95; 95% CI 0.57-1.57). CONCLUSION Low-dose CC does not reduce pregnancy or live birth rate per transferred embryo. It can be used in infertility treatment without negatively affecting the endometrium and implantation.

Abstract
BACKGROUND Granulocyte colony-stimulating factor (G-CSF) administration increased ovarian preantral follicles and anti-Müllerian hormone (AMH) in animal models with diminished ovarian reserve. We investigated whether G-CSF priming before treatment with assisted reproductive technology (ART) improved embryo development and pregnancy rate while increasing serum AMH in patients with poor ovarian reserve. METHODS In this prospective randomized open-label controlled trial, 100 patients 20 to 42 years old with AMH below 2 ng/mL were randomized to priming or control groups (50 patients each). None had over 1 ART failure, day-3 follicle-stimulating hormone (FSH) above 30 IU/L, uterine anomalies, or a partner with azoospermia. All patients initially underwent conventional infertility treatment for 2 consecutive cycles in which the priming group but not controls received a subcutaneous G-CSF priming injection during the early luteal phase. Each group then underwent 1 cycle of in vitro fertilization/intracytoplasmic sperm injection and fresh embryo transfer (IVF/ICSI-fresh ET), followed by cryopreserved ET if needed until live birth or embryo depletion. AMH was measured before and after priming. RESULTS Fertilization rate, embryonic development, and implantation rate by fresh ET were significantly improved by priming. Clinical and ongoing pregnancy rates by IVF/ICSI-fresh ET were significantly higher with priming (30% and 26% in 47 ART patients; 3 delivered with conventional treatment) than in controls (12% and 10% in 49 ART patients; 1 dropped out). With priming, significantly more patients achieved cryopreservation of redundant blastocysts. The cumulative live birth rate was 32% in 50 patients with priming, significantly higher than 14% in 49 controls (relative risk, 2.8; 95% confidence interval, 1.04-7.7). Infants derived from priming had no congenital anomalies, while infant weights, birth weeks, and Apgar scores were similar between groups. Among 4 variables (age, day-3 FSH, AMH, and priming), logistic regression significantly associated age and priming with cumulative live birth. Priming significantly increased serum AMH. No adverse effects of priming were observed. CONCLUSION G-CSF priming improved embryonic development and pregnancy rate during ART treatment and increased AMH in patients with poor ovarian reserve. Enhanced preantral follicle growth likely was responsible. TRIAL REGISTRATION UMIN registration in Japan (UMIN000013956) on May 14, 2014. https://www.umin.ac.jp/ctr/index.htm .

Abstract
PURPOSE To analyze the influence of Caucasian mitochondrial haplogroups on controlled ovarian stimulation outcome (COS), embryo (E), and pregnancy success. METHODS In a Caucasian population (n = 517) undergoing COS, mitochondrial haplogroups and physiological parameters were determined. Patients were classified, according to Bologna criteria, as good (>3)/poor ≤3) responder, on dependence of recruited oocytes (RO), and in pregnancy/non-pregnancy groups. Haplogroups were determined by sequencing mitochondrial hypervariable sequence I and confirmed by polymerase chain reaction (PCR), followed by restriction fragment length polymorphisms (RFLP). RESULTS The rank of total dose of FSH (TD FSH) was similar in all clusters/haplogroups, except in JT, which is narrower (950-3,650 IU), particularly in T (1,350-3,650 IU). The statistical analysis showed higher RO and E in JT when compared to U, although it was only Uk which accumulated significantly in pregnancy respect to JT. Pearson's correlations between TD FSH and RO showed negative statistical significance in all population (P = 0.001), H (P = 0.03), JT (P = 0.01), and T (P = 0.03). The percentage of contribution of TD FSH on RO was almost nine times in the JT cluster as compared to all population one. CONCLUSIONS JT cluster shows a different influence of TD FSH on RO. JT cluster shows higher RO and E than U, but it is Uk which exhibits a significant higher pregnancy rate than JT. The negative influence of the JT cluster on pregnancy success strongly suggests that the m.4216 T > C polymorphism could be responsible.

Abstract
Although previous studies have examined the relationship between the sperm DNA fragmentation index and fertility in stallions, other aspects of chromatin structure or packaging and fertility have not been explored. In the present study, relationships between fertility and DNA fragmentation index, protamine deficiency, total thiols, free thiols and disulfide bonds in stallion spermatozoa were investigated. Ejaculates (n = 36) were collected from 12 stallions and extended to prepare semen doses for insemination. One dose from each ejaculate was sent to the Swedish University of Agricultural Sciences. Aliquots of semen were stained for flow cytometry with acridine orange for the Sperm Chromatin Structure Assay (DNA fragmentation Index, %DFI), with chromomycin A3 (CMA) for protamine deficiency, and with monobromobimane (mBBr) for detection of total and free thiols and disulfide bonds. Per season pregnancy rates after insemination were obtained. Mixed linear models were used to analyze data. Negative correlations were found between pregnancy rate and %DFI (r = -0.35, P < 0.03) and pregnancy rate and free thiols (r = -0.60, P < 0.0001). Furthermore, there were positive correlations between total thiols and disulfide bonds (r = 0.95, P < 0.0001), and protamine and disulfide bonds (r = 0.4100, P < 0.01986). Since chromatin integrity, protamine deficiency and packaging were all associated with fertility, a combination of these factors could be used as a biomarker of fertility when assessing ejaculates.

Abstract
The objectives of this study were to investigate whether estrous activity and its impact on pregnancy outcomes would differ in heifers subjected to a 5 d CO-Synch plus progesterone releasing intravaginal device (PRID) protocol with or without an initial GnRH treatment. Holstein Heifers (n = 308) were fitted with a collar-mounted automated activity monitoring system approximately 1 week prior to the initiation of the synchronization protocol (Day -7). Heifers were assigned randomly to a 5 d CO-Synch plus PRID protocol either with (GnRH; n = 154) or without (NGnRH; n = 154) an initial administration of 100 μg of GnRH at the time of PRID insertion (Day 0). Heifers received a single administration of 500 μg of cloprostenol (PGF) at the time of PRID removal (Day 5) and again 24 h later (Day 6). Approximately 72 h after PRID removal (Day 8), heifers were timed-inseminated (TAI) and concurrently 100 μg of GnRH was administered to those not exhibiting estrus. All inseminations were done by one of two technicians using either sex-sorted (n = 252) or conventional (n = 56) frozen-thawed semen. Transrectal ultrasonography was done on Day 0 to determine ovarian cyclicity and normalcy of the reproductive tract and 30 and 45 d post-TAI to determine and confirm pregnancy, respectively. The percentage of heifers determined to be in estrus following PRID removal was greater in the GnRH than in the NGnRH group (94 vs. 82%, respectively; P < 0.01). The mean interval from PRID removal to the onset of estrus was shorter for GnRH- than NGnRH-treated heifers (50.8 vs. 59.2 h, respectively; P < 0.01). Pregnancy per AI (P/AI) at 30 d post-TAI tended to be greater for GnRH than NGnRH heifers (68 vs. 59%, respectively; P = 0.1). However, P/AI at 45 d post-TAI (65 vs. 57%, respectively) and pregnancy loss between 30 and 45 d post-TAI (6 vs. 4.5%, respectively) did not differ. The association between the interval from PRID removal to the onset of estrus and P/AI at 30 d post-TAI was linearly negative for GnRH heifers; for every 1 h increase in the interval from PRID removal to the onset of estrus, the predicted probability of P/AI at 30 d post-TAI tended (P = 0.08) to be reduced by 2.7%. The association between the interval from PRID removal to the onset of estrus and P/AI at 30 d post-TAI was not significant for NGnRH heifers. In addition, the interval from TAI to subsequent estrus, in non-pregnant heifers, was approximately 3 d longer for the GnRH than the NGnRH group (20.7 vs. 17.5 d, respectively). In summary, the initial GnRH treatment in a 5 d CO-Synch plus PRID protocol increased estrus expression and reduced the interval from PRID removal to the onset of estrus in Holstein heifers and tended to increase P/AI at 30 d, but did not affect P/AI at 45 d post-TAI.

Abstract
BACKGROUND Uterine artery embolisation is well established as a treatment for symptomatic fibroids, however, there remain some uncertainties. We have carried out a focused literature review on three particularly challenging aspects - post-procedure fertility, symptomatic adenomyosis and large volume fibroids and uteri, to enable operators to utilise evidence-based guidance in patient selection, consent, and management. REVIEW Literature searches were performed of the PubMed/Medline, Google scholar, EMBASE and Cochrane databases. The outcomes of our analysis of studies which recorded fertility rates in women desiring pregnancy following UAE for symptomatic fibroids found an overall mean pregnancy rate of 39.4%, live birth rate of 69.2% and miscarriage rate of 22%. The major confounding factor was patient age with many studies including women over 40 years who already have lower fertility compared to younger cohorts. Miscarriage rates and pregnancy rates in the studies analysed were comparable to the age matched population. Treatment of pure adenomyosis and adenomyosis with co-existing uterine fibroids with UAE has been shown to produce symptomatic improvement with better outcomes in those with combined disease. Although the effectiveness is not as high as it is in pure fibroid disease, UAE provides a viable and safe alternative for patients seeking symptom relief and uterine preservation. Our analysis of studies assessing the outcomes of UAE in patients with large volume uteri and giant fibroids (> 10 cm) demonstrate no significant difference in major complication rates demonstrating that fibroid size should not be a contraindication to UAE. CONCLUSION Our findings suggest uterine artery embolisation can be offered to women desiring pregnancy with fertility and miscarriage rates comparable to that of the age-matched general population. It is also an effective therapeutic option for symptomatic adenomyosis as well as for the treatment of large fibroids > 10 cm in diameter. Caution is advised in those with uterine volumes greater than 1000cm3. It is however clear that the quality of evidence needs to be improved on with an emphasis on well-designed randomised controlled trials addressing all three areas and the consistent use of validated quality of life questionnaires for outcome assessment to enable effective comparison of outcomes in different studies.

Abstract
OBJECTIVE The aim of the study was to investigate pregnancy and live birth rate after surgical resection of rectosigmoid deep infiltrating endometriosis (DIE), and study if complications affect these rates. STUDY DESIGN Historical case series. 193 patients with rectosigmoid DIE and pregnancy intention undergoing a rectosigmoid resection for DIE from January 2009 to May 2019. All operations were performed at the Department of Obstetrics and Gynecology, Aarhus University Hospital, Denmark. Surgical and fertility outcome data were obtained through patient files. Anonymized data was analyzed statistically. Normally distributed continuous variables are stated as means, categorical data as percentages and time to pregnancy as Kaplan-Meier failure function. Live birth rates stratified on complications were tested with chi2 test. RESULTS 117 patients became pregnant postoperatively with a pregnancy and live birth rate of 60.6% and 53.9%, respectively. 39 patients (20.2%) became pregnant spontaneously and 78 patients (40.4%) by intrauterine insemination or assisted reproductive technologies. Median time to pregnancy after surgery was 12.4 months (range: 0.4-58). Clavien-Dindo complication grade III (none grade IV) was registered among 16.6%. These patients had pregnancy and live birth rates of 50%, not statistically significantly different from those without complications. CONCLUSIONS Postoperative pregnancy and live birth rates after resection of rectosigmoid endometriosis in this study are in line with conservative treatment, when comparing with the literature. Interestingly, complications (Clavien-Dindo grade III) did not affect live birth rate or time to pregnancy.

Abstract
To better understand reproductive physiology of humpback whales Megaptera novaeangliae that reside in Hawai'i and Alaska, enzyme immunoassays were validated for both progesterone and testosterone in free-ranging and stranded animals (n = 185 biopsies). Concentrations were analyzed between different depths of large segments of blubber taken from skin to muscle layers of stranded female (n = 2, 1 pregnant, 1 non-pregnant) and male (n = 1) whales. Additionally, progesterone metabolites were identified between pregnant (n = 1) and non-pregnant (n = 3) females using high pressure liquid chromatography (HPLC). Progesterone concentrations were compared between juvenile (i.e., sexually immature), lactating, and pregnant females, and male whales, and pregnancy rates of sexually mature females were calculated. Based on replicate samples from ship struck animals collected at 7 depth locations, blubber containing the highest concentration of progesterone was located 1 cm below the skin for females, and the highest concentration of testosterone was in the skin layer of one male whale. HPLC of blubber samples of pregnant and non-pregnant females contain different immunoreactive progesterone metabolites, with the non-pregnant female eluate comprised of a more polar, and possibly conjugated, form of progesterone than the pregnant female. In females, concentrations of progesterone were highest in the blubber of pregnant (n = 28, 28.6 ± 6.9 ng/g), followed by lactating (n = 16, 0.9 ± 0.1 ng/g), and female juvenile (n = 5, 1.0 ± 0.2 ng/g) whales. Progesterone concentrations in male (n = 24, 0.6 ng/g ± 0.1 ng/g) tissues were the lowest all groups, and not different from lactating or juvenile females. Estimated summer season pregnancy rate among sexually mature females from the Hawai'i stock of humpback whales was 0.562 (95 % confidence interval 0.528-0.605). For lactating females, the year-round pregnancy rate was 0.243 (0.09-0.59), and varies depending on the threshold of progesterone assumed for pregnancy in the range between 3.1 and 28.5 ng/g. Our results demonstrate the synergistic value added when combining immunoreactive assays, HPLC, and long-term sighting histories to further knowledge of humpback whale reproductive physiology.

Abstract
PURPOSE This study aimed at evaluating the value of uterine biophysical profile (UBP) scoring to predict the pregnancy rate after IUI. METHODS This prospective study was carried out on 85 women who were referred to our tertiary teaching center with infertility of male factor or unknown etiology infertility in 2018. To measure the uterine biophysical criteria, transvaginal ultrasonography (TVS) was performed on the day of beta-human chorionic gonadotropin (B-hCG) injection, and the results were evaluated based on positive B-hCG. RESULTS 85 patients were included with a mean age of 30 years; of those 12 (14.1%) were able to conceive. UBP (p = 0.151) and it's parameters (including endometrial thickness, number of endometrial layers, myometrial echogenicity, uterine artery pulsatility index, myometrial blood flow internal to arcuate vessels, endometrial blood flow in the third zone of endometrium, myometrial contraction frequency, and ovarian follicle (OF) size [p = 0.05, 0.89, 0.59, 0.79, 1, 1, 0.59, and 0.77, respectively]) were not significantly associated with pregnancy rate. 91.7% of the cases with positive pregnancy test results, had a UBP score of > 13; however, UBP score was not meaningfully associated with IUI treatment success rate (p = 0.15). CONCLUSIONS UBP scoring system seems to need more data for external validation, or it might require modifications before implementation, as it may cause false reassurance.

Abstract
BACKGROUND Malignant ovarian germ cell tumors (MOGCT) are rare and frequently occur in women of young and reproductive age and the oncologic and reproductive outcomes after fertility-sparing surgery (FSS) for this disease are still limited.
AIM To evaluate the oncology and reproductive outcomes of MOGCT patients who underwent FSS.
METHODS All MOGCT patients who underwent FSS defined as the operation with a preserved uterus and at least one side of the ovary at our institute between January 2005 and December 2020 were retrospectively reviewed.
RESULTS Sixty-two patients were recruited for this study. The median age was 22 years old and over 77% were nulliparous. The three most common histology findings were immature teratoma (32.2%), dysgerminoma (24.2%), and yolk sac tumor (24.2%). The distribution of stage was as follows; Stage I, 74.8%; stage II, 9.7%; stage III, 11.3%; and stage IV, 4.8%. Forty-three (67.7%) patients received adjuvant chemotherapy. With a median follow-up time of 96.3 mo, the 10-year progression-free survival and overall survival were 82.4% and 91%, respectively. For reproductive outcomes, of 43 patients who received adjuvant chemotherapy, 18 (41.9%) had normal menstruation, and 17 (39.5%) resumed menstruation with a median time of 4 mo. Of about 14 patients who desired to conceive, four were pregnant and delivered good outcomes. Only one case was aborted. Therefore, the successful pregnancy rate was 28.6%
CONCLUSION The oncology and reproductive outcomes of MOGCT treated by FSS are excellent. Many patients show a long survival time with normal menstruation. However, the obstetric outcome is not quite satisfactory.

Abstract
The objective of this study was to evaluate the impact of endometrial scratch on the pregnancy rate among women with previous failed intrauterine insemination (IUI). A systematic search was done in PubMed, Cochrane Library, Scopus, and ISI web of science from inception to November 2021. We selected randomized clinical trials (RCTs) that compared endometrial scratch in the intervention group versus placebo or no intervention in the control group among infertile women with previous failure of IUI regarding different pregnancy outcomes. Revman software was utilized for performing our meta-analysis. Our main outcomes were biochemical pregnancy, clinical pregnancy, and live birth rates. Five RCTs met our inclusion criteria with a total number of 989 patients. We found endometrial scratch significantly improved the biochemical and clinical pregnancy rates in comparison with the control group among women with previous IUI failure (p < 0.001). Moreover, the live birth rate was significantly increased among the endometrial scratch group (RR = 2.00, 95% CI [1.20, 3.34], p = 0.008). In conclusion, endometrial scratch is effective in improving pregnancy outcomes among women with previous IUI failure. More trials are required to confirm our findings.

Abstract
Purpose To develop a predictive score for the success of intrauterine insemination (IUI) based on clinical parameters. Methods We performed a retrospective cohort study evaluating the homologous IUI cycles performed at a single university-based reproductive medical center between 2009 and 2017. The primary outcome measure was pregnancy, defined as positive serum human chorionic gonadotropin (hCG) 12–14 days after IUI. Predictive factors for pregnancy after IUI were identified, and a predictive score was developed using a multivariable continuation ratio model. Results Overall, 1437 IUI cycles in 758 couples were evaluated. We found a per cycle pregnancy rate of 10.9% and a cumulative pregnancy rate of 19.4%. In a multivariable analysis, the probability of pregnancy was negatively associated with female age ≥ 35 years (OR 0.63, 95% CI 0.41–0.97, p = 0.034), endometriosis, unilateral tubal factor, or anatomical alteration (OR 0.54, 95% CI 0.33–0.89, p = 0.016), anti-Mullerian hormone (AMH) < 1 ng/ml (OR 0.50, 95% CI 0.29–0.87, p = 0.014), and total progressive motile sperm count (TPMSC) < 5 mil (OR 0.47, 95% CI 0.19–0.72, p = 0.004). We developed a predictive clinical score ranging from 0 to 5. Following 3 cycles, couples in our cohort with a score of 5 had a cumulative probability of achieving pregnancy of nearly 45%. In contrast, couples with a score of 0 had a cumulative probability of only 5%. Conclusion IUI success rates vary widely depending on couples’ characteristics. A simple to use score could be used to estimate a couple’s chance of achieving pregnancy via IUI, facilitating individualized counseling and decision-making.
