Shen L, Zeng H, Fu Y, Ma W, Guo X, Luo G, Hua R, Wang X, Shi X, Wu B, Luo C, Quan S. Specific plasma microRNA profiles could be potential non-invasive biomarkers for biochemical pregnancy loss following embryo transfer. BMC Pregnancy Childbirth 2024; 24:351. [PMID: 38720272 PMCID: PMC11080217 DOI: 10.1186/s12884-024-06488-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Accepted: 04/07/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND Plasma microRNAs act as biomarkers for predicting and diagnosing diseases. Reliable non-invasive biomarkers for biochemical pregnancy loss have not been established. We aim to analyze the dynamic microRNA profiles during the peri-implantation period and investigate if plasma microRNAs could be non-invasive biomarkers predicting BPL. METHODS In this study, we collected plasma samples from patients undergoing embryo transfer (ET) on ET day (ET0), 11 days after ET (ET11), and 14 days after ET (ET14). Patients were divided into the NP (negative pregnancy), BPL (biochemical pregnancy loss), and CP (clinical pregnancy) groups according to serum hCG levels at day11~14 and ultrasound at day28~35 following ET. MicroRNA profiles at different time-points were detected by miRNA-sequencing. We analyzed plasma microRNA signatures for BPL at the peri-implantation stage, we characterized the dynamic microRNA changes during the implantation period, constructed a microRNA co-expression network, and established predictive models for BPL. Finally, the sequencing results were confirmed by Taqman RT-qPCR. RESULTS BPL patients have distinct plasma microRNA profiles compared to CP patients at multiple time-points during the peri-implantation period. Machine learning models revealed that plasma microRNAs could predict BPL. RT-qPCR confirmed that miR-181a-2-3p, miR-9-5p, miR-150-3p, miR-150-5p, and miR-98-5p, miR-363-3p were significantly differentially expressed between patients with different reproductive outcomes. CONCLUSION Our study highlights the non-invasive value of plasma microRNAs in predicting BPL.

Abstract
OBJECTIVE An increasing number of research have emerged to compare the pregnancy outcomes between the natural cycle and the hormone replacement therapy (HRT) cycle in preparing the endometrium for frozen-thawed embryo transfer (FET), but the results are controversial. This prospective randomized controlled study was hence designed to obtain more solid evidence. MATERIALS AND METHODS In this study, patients with regular menstrual cycle length (21-35 days) who underwent FET between January 2010 to December 2017 were recruited for this study. Upon further filtering with the selection criteria of patients being, a total of 405 patients were recruited and randomized. Finally, analysis was performed on 384 patients: 178 belonged to the natural cycle group whereas the remaining 206 were in the HRT group. The primary outcome was live birth rate, while the secondary outcomes were implantation rate, clinical pregnancy rate, early miscarriage rate, late miscarriage rate, multiple birth rate and low birth weight rate. RESULTS The live birth rate (37.6% vs 30.1%, p = 0.119) of natural cycle group were higher than those of the hormone replacement therapy group, although the difference was not significant. The secondary outcomes were not found to differ significantly between the two groups. Nonetheless, the endometrium was found to be thicker in the natural cycle group (10.75 mm) than the HRT group (9.00 mm) (p < 0.001). CONCLUSION No significant differences were observed between the pregnancy outcomes of the natural cycle group and the HRT group which comprised of patients with regular menstrual cycle length.

Abstract
The purpose of this study was to analyze acupuncture treatment methods and acupoint used to treat infertility in the last decade. The data were retrieved from 2010.1 to 2021.8. using national and international electronic databases (PubMed, EMBASE, OASIS, NDSL, and KISS). “Infertility,” “sterility,” “acupuncture,” “electroacupuncture,” “bloodletting,” “pharmacopuncture,” were used as search terms. All studies were mainly concerned with acupuncture treatment of infertility, but the studies which were not related included; (1) infertility or acupuncture treatment; (2) animal studies; (3) review/meta/protocol or clinical study; comparative studies and case reports which were excluded from this review. Only clinical trials for acupuncture treatment of infertility were included in this review (n = 18). For infertility treatment studies using acupuncture, polycystic ovarian syndrome was the main cause of infertility, the most common acupoint used was CV4, CV3, CV6, SP6, BL23, and the treatment effect significantly improved in the group receiving acupuncture treatment compared with the control group, or the group taking Western medicine alone. In some studies, the group using acupuncture treatment did not show side effects. Acupuncture is an effective treatment for infertility.

Abstract
The aim of this study was to investigate which factors contribute to the incidence of biochemical pregnancy (BP) in intracytoplasmic sperm injection (ICSI) cycles. This cohort study included cycles performed from June 2010 to September 2016 in a private, university-affiliated IVF centre. Cycles were split into four groups, depending on the pregnancy outcomes: Clinical Pregnancy (CP, n = 903), Biochemical Pregnancy (BP, n = 55), Miscarriage (MI, n = 142) and Negative Pregnancy (NP, n = 2034). The effects of ovarian stimulation, laboratory data and seminal parameters on pregnancy outcomes were evaluated using adjusted general linear models. Discriminant analyses were conducted to construct a model for pregnancy prediction and to establish cut-offs for BP. The total sperm count (p = 0.035), total and progressive sperm motility (p = 0.001 and p = 0.023, respectively), total motile sperm count (TMSC, p = 0.029) and the endometrial thickness (p < 0.001) were lower among BP group cycles. Lower rates of high-quality cleavage-stage embryos were observed in the BP group compared to CP and MI groups (p < 0.001). In discriminant analyses, cut-offs for BP prediction were established for the following factors: endometrial thickness < 11 mm, sperm motility < 55.5% and total dose of follicle-stimulating hormone (FSH)> 2400 IU. The incidence of biochemical pregnancy was four times higher when the aforementioned factors did not meet the defined cut-offs. The combination of suboptimal endometrial development and poor seminal and embryo quality contribute to an increased incidence of biochemical pregnancy in ICSI cycles.

Abstract
Luteinized unruptured follicle (LUF) syndrome is one of the intractable ovulation disorders that are commonly observed during cycles of treatment with ovulation inducers, for which no effective therapy other than assisted reproductive technology is available. Here, we investigated whether granulocyte colony-stimulating factor (G-CSF) could prevent the onset of LUF syndrome. We analyzed the effects of G-CSF in 68 infertile women with LUF syndrome who received ovulation induction (clomiphene + human chorionic gonadotropin [hCG] therapy or follicle-stimulating hormone + hCG therapy). G-CSF (lenograstim, 100 μg) was administered subcutaneously. Onsets of LUF syndrome were compared between the cycle during which G-CSF was given in combination with the ovulation inducer (ie, the G-CSF treatment cycle) and the subsequent cycle during which only the ovulation inducer was given (ie, the G-CSF nontreatment control cycle). The results showed that LUF syndrome recurred in only 3 cycles during the G-CSF treatment cycle (4.4% [3/68 cycles]), whereas LUF syndrome recurred in 13 cycles during the subsequent G-CSF nontreatment control cycle (19.1% [13/68 cycles]). The additional use of G-CSF significantly prevented the onset of LUF syndrome during ovulation induction (P = 0.013, McNemar test). No serious adverse reactions because of the administration of G-CSF were observed. In conclusion, our findings indicate that G-CSF may become a useful therapy for LUF syndrome.

Abstract
OBJECTIVE To examine associations between environmental exposure to perfluoroalkyl substances (PFASs) and ovarian hormone concentrations in naturally cycling women. DESIGN E2 and P were measured in saliva samples collected daily for a single menstrual cycle and concentrations of PFASs (including perfluoroctane sulfonate [PFOS] and perfluoroctanoic acid) were measured in serum samples collected during the same cycle. SETTING Not applicable. PATIENT(S) A total of 178 healthy, naturally cycling women, aged 25-35 years. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Mean follicular E2 (cycle days -7 to -1, where 0 is the day of ovulation); mean luteal P (cycle days +2 to 10). RESULT(S) Among nulliparous, but not parous women, PFOS concentrations were inversely associated with E2 (β = -0.025, 95% CI -0.043, -0.007) and P (β = -0.027, 95% CI -0.048, -0.007). Similar, but weaker results were observed for perfluorooctanesulfonic acid. No associations were observed between other PFASs (including perfluoroctanoic acid) and ovarian steroid concentrations, nor were any associations noted in parous women. CONCLUSION(S) Our results demonstrate that PFOS and perfluorooctanesulfonic acid may be associated with decreased production of E2 and P in reproductive age women. These results suggest a possible mechanism by which PFASs affect women's health, and underscore the importance of parity in research on PFASs and women's reproductive health.

Abstract
PURPOSE To identify whether biochemical pregnancy (BP) and spontaneous abortion (SA) cases have the same clinical characteristics in assisted reproductive therapy (ART), and to assess its predictive value for the subsequent cycles. METHODS Retrospectively reviewed 12,174 cycles in the first in vitro fertilization and embryo transfer (IVF-ET) cycle from January 2009 to December 2012 of Peking University Third Hospital Reproductive Medical Center. Besides those patients who reached ongoing pregnancy stage, 7,598 cases were divided into three groups: group 1, lack of pregnancy (n = 6,651); group 2, BP (n = 520); and group 3, SA (n = 427). We compared the basic status of patients of the three groups, including ages, body mass index, basic hormone levels, controlled ovarian hyperstimulation protocols, amount of gonadotropin use, and endometrium thickness. The reproductive outcome of the next embryo transfer cycles of the three groups was analyzed. RESULTS 520 patients ended as BP, and 427 patients ended as SA. The age, primary infertility proportion, body mass index, basic FSH level and basic E2 level were similar among groups. Endometrial thickness, controlled ovarian hyperstimulation protocol, Gn dosage, average oocyte retrieval and ET numbers were also similar. Multivariate analysis showed that only the age (P = 0.037, OR 1.060, 95 % CI 1.001-1.120) and endometrium thickness on hCG administration day (P = 0.029, OR 1.136, 95 % CI 1.013-1.275) may result in the differences between BP and SA groups. In the subsequent ET cycles, the total BP rate was 4.37 %, clinical pregnancy rate was 37.28 %, and miscarriage rate was 8.18 %. The clinical pregnancy rates were similar among groups. However, BP group still had the highest BP rate (P < 0.05, 7.97 vs. 4.01 % and 5.28 %), BP and SA group had higher miscarriage rate (P < 0.05, 11.76 % and 14.75 vs. 7.41 %). CONCLUSION BP and SA in first IVF cycles had negative predictive value for subsequent ART outcomes.

Abstract
Assisted reproductive technology (ART) has revolutionized the management of subfertility as many couples who previously had no hope of achieving a pregnancy are able to do so. Several factors contribute to the successful outcome of assisted conception. The period of waiting for the pregnancy test after assisted conception could be very crucial to the patient. One outcome of assisted conception could be a positive pregnancy test which could lead to a clinical pregnancy resulting in a live birth, clinical pregnancy resulting in a miscarriage or a biochemical pregnancy. A negative pregnancy test, failure to fertilise and failure to respond to stimulation usually lead to a big blow to the couple. As far as biochemical pregnancy is concerned, its exact aetiology remains unknown. There are no definite predictive factors for its occurrence that can be remedied in subsequent cycles. Several associated aetiologies have been suggested in the literature. This review aims at addressing the issue of biochemical pregnancy after assisted conception as a prelude to conducting further studies to assess if there are any predictive factors for its occurrence.

Abstract
Objective To compare the IVF outcomes of mild ovarian stimulation with conventional ovarian stimulation in poor responders. Methods From 2004 to 2009, 389 IVF cycles in 285 women showed poor responses (defined as either a basal FSH level ≥12 mIU/mL, or the number of retrieved oocytes ≤3, or serum E2 level on hCG day <500 pg/mL) were analyzed, retrospectively. In total, 119 cycles with mild ovarian stimulation (m-IVF) and 270 cycles with conventional ovarian stimulation (c-IVF) were included. Both groups were divided based on their age, into groups over and under 37 years old. Results The m-IVF group was lower than the c-IVF group in the duration of stimulation, total doses of gonadotropins used, serum E2 level on hCG day, the number of retrieved oocytes, and the number of mature oocytes. However, there was no significant difference in the number of good embryos, the number of transferred embryos, the cancellation rate, or the clinical pregnancy rate. In the m-IVF group over 37 years old, the clinical pregnancy rate and live birth rate were higher when compared with the c-IVF group, but this result was not statistically significant. Conclusion In poor responder groups, mild ovarian stimulation is more cost effective and patient friendly than conventional IVF. Therefore, we suggest that mild ovarian stimulation could be considered for poor responders over 37 years old.

Abstract
PURPOSE To determine factors instrumental in achieving a clinical pregnancy in assisted reproductive technology (ART) patients. METHODS This study included 205 women undergoing their first ART cycle. Univariate and multivariate analyses were performed for patient demographics, in vitro production data, and factors associated with embryo transfer. Odds ratios (OR) were performed where appropriate. RESULTS Our analyses indicated that age (OR: 0.879), specific year in which the cycle was performed (OR: 2.959), and use of intracytoplasmic sperm injection (OR: 2.867) altered potential pregnancy rate. In addition, percent fertilization (OR: 1.028), number of embryos transferred (OR: 1.842), type of catheter used to transfer the embryos (OR: 0.377), presence of blood on the catheter (OR .414), and embryologist (OR: 2.338) also altered pregnancy rate. CONCLUSIONS Our data indicate patients' age, use of the Cook catheter, and presence of blood on the catheter reduce pregnancy rates. Performing ART in 1999, using ICSI, increasing fertilization rate, increasing number of embryos transferred (albeit less desirable when the chance of multiple gestation may occur), and transferring embryos via a particular embryologist, improve pregnancy rates.

Abstract
OBJECTIVE A trial was conducted to examine the effects of a timed sequence of hormone supplementation (HS) with oral estradiol (E(2)) and vaginal progesterone (P) following clomiphene citrate (CC) therapy to determine if this regimen can increase pregnancy rates in CC cycles. METHODS This study was a randomized, open-label study. Seventy-one oligo-ovulatory women were randomized into one of two groups; those who received CC plus HS (n = 34) and those who received no HS (n = 37). All subjects received 100 mg CC orally from cycle days 3 to 7. Subjects randomized to HS started oral E(2) at a dose of 1.5 mg BID on cycle day 8. All subjects monitored urine luteinizing hormone (LH) levels starting on cycle day 10; additionally, intercourse was encouraged starting on cycle day 10. Subjects receiving HS discontinued E(2) with LH surge and started using vaginal progesterone gel (Prochieve 8%) daily for 2 weeks starting 3 days after LH surge. All subjects had a pregnancy test (Assure) 2 weeks after LH surge. If pregnancy occurred, the subject continued using vaginal progesterone gel daily for an additional 10 weeks. RESULTS Sixty-five (65) subjects (31 CC plus HS and 34 no HS) completed the study. Fifty of the 65 subjects (77%) (23 [74%] CC plus HS, 27 [79%] no HS) who completed the study ovulated. The mean (range) progesterone (P) concentration for these 50 subjects was 1662.6 (340 to 5690) ng/dL, and mean and median P levels were slightly higher, but not statistically significant, in the HS group compared with the no HS group. Pregnancy rates were clinically, but not statistically, different between the treatment groups. Of the 50 responders, 12% became pregnant (17% CC plus HS, 7% no HS). CONCLUSION These findings show a potential supportive effect on pregnancy rates in the CC plus oral estradiol and vaginal progesterone gel group compared to CC alone that needs to be confirmed in a larger study.

Abstract
Along the menstrual cycle and during pregnancy, small blood vessels proliferate within the uterus and the ovulating ovary. Angiogenic factors such as VEGF are involved in this phenomenon. In the ovulating ovary, neo-angiogenesis spreads progressively inside the dominant follicle wall and plays a role in the maintenance of the corpus luteum, under the influence of LH (or HCG during pregnancy). In ART, the measure of the blood flow is interesting since it correlates to the number and quality of harvested oocytes. Follicle hypoxia may impair chromosomal organization and separation within the oocyte. This neo-angiogenesis is also important in endometrium, in particular for embryo implantation. Ultrasounds with Doppler allow to estimate the endometrial receptivity, especially in IVF cycles. It is assumed that chance for ongoing pregnancy is almost zero if: endometrial thickness is < 8 mm; uterine pulsatility index (PI) is > 3. Doppler ultrasounds are a useful and even mandatory complement to standard vaginal ultrasonoghraphy in ART. It can be viewed as an indicator of the endometrial and follicular "well-being".

Abstract
OBJECTIVE To evaluate the ovarian follicular dynamics of cycle modification with the aromatase inhibitor letrozole compared with clomiphene citrate in normal ovulatory women. DESIGN Randomized double-blind controlled trial. SETTING Tertiary care hospital. PATIENT(S) Nineteen ovulatory female volunteers, ages 18-35 years. INTERVENTION(S) Subjects were monitored in one control cycle. Subjects then received either letrozole 2.5 mg daily or clomiphene citrate 50 mg daily on days 5-9 after menses. MAIN OUTCOME MEASURE(S) Number of mature follicles, endometrial thickness and endometrial pattern at ovulation, and follicular profiles of LH, FSH, and E(2). RESULT(S) The number of mature follicles at the LH surge in natural cycles was 1.0 with an exaggerated response seen for treatment both with clomiphene and letrozole. There was no difference in the endometrial thickness at midcycle during either the natural cycles or the medicated cycles. LH surges and spontaneous ovulation were documented in all natural and medicated cycles. When measured daily, follicular profiles of LH and FSH are similar between the groups in both the natural and medicated cycles. In the medicated cycles, clomiphene results in a significant increase in E(2) levels, while E(2) levels in letrozole-stimulated cycles appeared lower than in natural cycles. CONCLUSION(S) Transient inhibition of aromatase activity in the early follicular phase with the aromatase inhibitor letrozole results in stimulation of ovarian folliculogenesis similar to that seen with clomiphene citrate with no apparent adverse effect on endometrial thickness or pattern at midcycle.

Abstract
The understanding and control of embryo implantation represents the major challenge for assisted reproductive technologies. Along with developments in basic research and efforts to optimize embryo quality, the improvement of noninvasive and reliable methods to assess uterine receptivity constitutes an important step toward meeting such a challenge. Today, ultrasound-based approaches to evaluate endometrial echogenicity and uterine perfusion and contractility are available for practical use. Increasing evidence indicates that echogenic patterns of the endometrium reflect histologic processes that are involved in the establishment of receptivity. This constitutes a possible explanation for the reported association between premature hyperechogenic patterns of the endometrium and poor implantation rates. Nevertheless, additional studies aiming at correlating further morpho-biochemical events in the endometrium with its echogenicity patterns are needed. Further, developments in vascular assessment by Doppler, Doppler-related, and vascular detection technologies will also be instrumental in monitoring and improving vascular changes that lead to uterine receptivity. Finally, data supporting the hypothesis that uterine contractility, as visualized by ultrasound, influences in vitro fertilization-embryo transfer (IVF-ET) pregnancy rates encourage further investigation on both the regulation and control of uterine contractions. This article discusses some of the advantages and limitations of ultrasonographic assessments of uterine receptivity in the perspective of the new millennium.

Abstract
OBJECTIVES The aim of the study was to investigate whether endometrial thickness, endometrial pattern, endometrial movement and serum estradiol and progesterone affect the outcome of in vitro fertilization. METHODS Prospectively collected data of endometrial thickness, endometrial pattern and subendometrial activity were analyzed in 122 consecutive in vitro fertilization cycles. All measurements were made on the day of hCG administration (day -2), day of embryo transfer (day +2), day +6 and day +12. RESULTS It would appear that pregnant women tend to have a thicker endometrium on day +12 than non-pregnant women. There appears to be no appreciable difference between pregnant and non-pregnant women in endometrial movement and thickness, nor in serum estradiol and progesterone on day +2 and day +6. In combining three echographic variables (thickness, pattern and movement) and hormone level (estradiol and progesterone), only progesterone on day +12 could be used to predict the outcome. CONCLUSIONS Subendometrial contractility plays no important role in implantation on the day of embryo transfer or 4 days later.

Abstract
OBJECTIVE To determine whether endometrial echogenicity, assessed objectively by a computer-assisted system on the day of hCG administration, predicts endometrial receptivity in controlled ovarian hyperstimulation (COH) cycles for IVF-ET. DESIGN Prospective analysis. SETTING Assisted reproduction unit, Clamart, France. PATIENT(S) Two hundred twenty-one women (aged <38 years with a normal uterus and >/=2 grade A or B embryos transferred) undergoing 228 GnRH agonist and FSH/hCG cycles for IVF-ET. INTERVENTION(S) On the day of hCG administration, uterine ultrasound scans were digitized with an image analysis system. Endometrial echogenicity was assessed as the ratio of the extent of the hyperechogenic transformation over the whole endometrial thickness. According to this, cycles were sorted arbitrarily into six groups: <30% (n = 34), 31%-40% (n = 37), 41%-50% (n = 37), 51%-60% (n = 55), 61%-70% (n = 37), and >70% (n = 28). MAIN OUTCOME MEASURE(S) Pregnancy and implantation rates. RESULT(S) The groups were similar in regard to population characteristics, ovarian response to COH, and embryology data. Pregnancy rates (59%, 57%, 35%, 20%, 16%, and 11%, respectively) and implantation rates (35%, 23%, 17%, 6%, 7%, and 3%, respectively) fell progressively and significantly from the low-echogenicity group to the high-echogenicity group. CONCLUSION(S) The present results confirm and extend previous observations that advanced hyperechogenic transformation of the endometrium is associated with poor IVF-ET outcome.

Abstract
The rationale of ovulation induction is to achieve the development of a single follicle and ultimately a singleton healthy baby. Problems faced by women with anovulatory polycystic ovary syndrome are the sensitivity of the ovary to stimulation and health issues such as obesity. This chapter will discuss medical management including strategies to lose weight, address hyperinsulinaemia with insulin-sensitizing agents, such as metformin, and outline methods of ovulation induction from the usual first-line therapy of clomiphene citrate and the subsequent use of gonadotrophin therapy in clomiphene-resistant patients. Appropriately directed surgical ovulation induction with laparoscopic ovarian diathermy appears to be as efficacious as gonadotrophin therapy but will not be discussed in the context of this chapter.

Abstract
OBJECTIVE To determine whether endometrial activity is related to the occurrence of pregnancy in spontaneous menstrual cycles. DESIGN Prospective observational ultrasound evaluation of endometrial activity during fertility screening cycles. SETTING University hospital-based infertility clinic. PATIENT(S) Fifty-nine fertility screening cycles (ultrasound monitoring of follicle growth and ovulation, postcoital test, semen analysis, midluteal P, Chlamydia antibody determination, and tubal patency testing) were performed in 47 couples complaining of infertility. In 33 couples (37 cycles), no fertility impairing factors were found. Endometrial activity was analyzed in these cycles. INTERVENTION(S) Ultrasound examination was performed transvaginally throughout the cycle. MAIN OUTCOME MEASURE(S) Endometrial activity, wave pattern, pregnancy. RESULTS(S) Nine women conceived within the cycle studied. Conception cycles showed less-activity compared with nonconception cycles. Endometrial wavelike activity increased throughout the follicular phase and decreased after ovulation in conception and nonconception cycles. CONCLUSION(S) Endometrial activity is related to fecundability in a spontaneous cycle.
