Abstract
Many factors influence the final oocyte maturation, fertilisation, and early embryo development, and there are both similarities and differences between species. When comparing the advancement of assisted reproductive technologies (ARTs), the development in the bovine species is not far behind the medical front, with around one million in vitro-produced bovine embryos each year. This rate of progress is not seen in the other domestic species. This review aims to give an overview of the development and specific difficulties of in vitro embryo production in various domestic animal species, with the main focus on cows, pigs, and cats. In production animals, the aim of ARTs is commonly to increase the genetic progress, not to treat reproductive failure. The ARTs are also used for preservation of genetic diversity for the future. However, specifically for oocyte maturation, fertilisation, and early embryonic development, domestic mammals such as the cow and pig can be used as models for humans. This is particularly attractive from an animal welfare point of view since bovine and porcine oocytes are available in large numbers from discarded slaughterhouse material, thereby decreasing the need for research animals. Both for researchers on the animal and human medical fronts, we aim for the development of in vitro production systems that will produce embryos and offspring that are no different from those conceived and developed in vivo. Species-comparative research and development can provide us with crucial knowledge to achieve this aim and hopefully help us avoid unnecessary problems in the future.

[PMID: 32215822 DOI: 10.1007/s10815-020-01746-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Accepted: 03/12/2020] [Indexed: 11/26/2022] Open
Abstract
PURPOSE To determine if pre-implantation genetic testing (PGT) shifts the sex ratio (SER), the ratio of male to female births in a population normalized to 100 and typically stable at 105, following in vitro fertilization (IVF). METHODS Data from 2014 to 2016 was requested from the Society for Assisted Reproductive Technologies (SART) database including fresh and frozen transfer cycles. Women with a singleton live birth following a fresh or frozen autologous embryo transfer of a PGT blastocyst, non-PGT blastocyst, or non-PGT cleavage stage embryo were included. The SER between groups was compared using chi-square tests. Modified Poisson regression modeled the relative risk (RR) of having a male compared to a female among PGT blastocyst transfers versus non-PGT cleavage and blastocyst transfers adjusting for age, BMI, smoking status, race, parity, number of oocytes retrieved, and clinic region. RESULTS The SER was 110 among PGT blastocyst offspring, 107 among non-PGT blastocyst offspring (p = 0.005), and 99 among non-PGT cleavage offspring (p < 0.001). The risk of having a male infant was 2% higher among PGT blastocyst transfers compared to non-PGT blastocyst transfers (RR 1.02; 95% CI: 1.01, 1.04). The risk was 5% higher among PGT blastocyst transfers compared to non-PGT cleavage transfers (RR 1.05; 95% CI: 1.02, 1.07). The association between PGT and infant gender did not significantly differ by region (p = 0.57) or parity (p = 0.59). CONCLUSION Utilizing PGT shifts the SER in the IVF population from the standard of 105 to 110, increasing the probability of a male offspring.

Front Endocrinol (Lausanne) 2020; 11:615957. [PMID: 33542709 PMCID: PMC7851086 DOI: 10.3389/fendo.2020.615957] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 11/19/2020] [Indexed: 11/13/2022] Open
Abstract
INTRODUCTION Age, polycystic ovary syndrome (PCOS), low body mass index (BMI), high antral follicle count (AFC), increased anti-Muller hormone (AMH) levels, and elevated serum estradiol (E2) concentrations are risk factors for ovarian hyperstimulation syndrome (OHSS). However, data on the relationship between risk factors and OHSS severity in patients with PCOS are rare. OBJECTIVE This retrospective study examined the risk factors for OHSS and their effect on OHSS severity in patients with PCOS undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). METHOD The records of 2,699 women were reviewed and included in this study. These women were diagnosed with PCOS during their first IVF/ICSI cycle between January 2010 and December 2017. We analyzed the association between each of the interrogated risk factors (including female age, BMI, AFC, basal serum E2, and the number of oocytes retrieved) and OHSS. The effects of each risk factor on OHSS severity were further explored. Logistic regression was performed as part of the above analysis. RESULTS Of the 2,699 women with PCOS who underwent assisted reproductive technology (ART), 75.2% had a normal response to controlled ovarian hyperstimulation (COH), while 24.8% developed OHSS. All OHSS patients were younger and had lower BMIs and basal serum follicle-stimulating hormone (FSH) and E2 levels but higher AFCs than those in the normal group. AFC demonstrated a strong correlation with OHSS, with a cutoff value of 24 in patients with PCOS. A total of 19.5% of the patients had mild OHSS, while 80.5% had moderate OHSS. Compared with those in the moderate OHSS group, those in the mild OHSS group were older and had higher basal serum FSH levels and lower serum E2 and T levels. However, BMI and AFC were not different between the mild and moderate OHSS groups. Basal serum E2 showed a strong correlation with OHSS severity, with a cutoff value of 37.94 pg/ml. CONCLUSIONS AFC is a strong marker of OHSS, and basal serum E2 is the best predictor of OHSS severity in women with PCOS undergoing IVF treatment.

Abstract
OBJECTIVE Find trends in assisted reproduction (AR) in Czech Republic (CR) in years 2007-2017. DESIGN Retrospective national epidemiologic study. SETTINGS Department of Obstetric and Gynaecology, 1st Faculty of Medicine, Charles University and Genereal University Hospital, Prague. METHODS Data analysis of Czech Republic National Assisted Reproduction Register (NRAR) in years 2007-2017. RESULTS Analyses of NRAR show mild, but permanent growth of AR cycles in CR (42 773 in 2017), as well as the nubmer of AR centers (43 in 2017). Important part of AR in CR are Egg Donation cycles (5003 in 2017) and Oocyte Receipt cycles (6057 in 2017). Fertilisation by ICSI is permanently growing (96% cycles in 2017). CR succeeded in decreasing in the number of transferred embryos (average1, 18 embryo in 2017 for women up to 35 years) with the aim to prevent multiple pregnancies. AR efficacy can be evaluated by several indicators, and the age is the main parameter - since 32 years the fertility of women is diminishing. CONCLUSION Czech national assisted reproduction register provides detailed information about AR treatment and enables qualified decisions for Ministry of Health, health insurances, treatment doctors and patients.

Abstract
PURPOSE To provide a global scale report on a representative sample of the clinical embryology community depicting the practice of discarding supernumerary IVF embryos. METHODS A web-based questionnaire titled "Anonymous questionnaire on embryo disposal practices" was designed in order to ensure anonymous participation of practicing clinical embryologists around the world. RESULTS During a data collection period of 8 months, 703 filled-in questionnaires from 65 countries were acquired. According to the data acquired, the majority of practitioners, dispose of embryos by placing them directly in a trash can strictly dedicated for embryo disposal for both fresh and frozen cycles (39% and 36.7% respectively). Moreover, 66.4% of practitioners discard the embryos separately-case by case-at different time points during the day. Over half of embryologists (54%) wait until day 6 to discard the surplus embryos, while 65.5% do not implement a specially allocated incubator space as a designated waiting area prior to disposal. The majority of 63.1% reported that this is a witnessed procedure. The vast majority of embryologists (93%) do not employ different protocols for different groups of patients. Nonetheless, 17.8% reported the request to perform a ceremony for these embryos. Assessing the embryologists' perspective, 59.5% of participants stated that the embryology practice would benefit from a universally accepted and practiced protocol. CONCLUSION(S) This study uniquely provides insight into global embryo disposal practices and trends. Results highlight the divergence between reported practices, while indicating the significance on standardization of practice, with embryologists acknowledging the need for a universally accepted protocol implementation.

Use of fertility preservation services in female reproductive-aged cancer patients. Am J Obstet Gynecol 2019; 221:328.e1-328.e16. [PMID: 31108063 DOI: 10.1016/j.ajog.2019.05.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Revised: 05/09/2019] [Accepted: 05/13/2019] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The objective of the study was to determine the rates and predictors of fertility preservation services among reproductive-aged women with common cancers in the United States. STUDY DESIGN We used the MarketScan database to identify women 18-45 years of age with lung, breast, colorectal, or cervical cancer who underwent surgery and chemotherapy from 2009 through 2016. Services from 3 months before to 3 months after chemotherapy for evaluation for fertility preservation, laboratory testing for fertility evaluation, and fertility-preserving procedures were captured. Multivariable models were used to assess the factors associated with the use of fertility-preservation services. RESULTS A total of 18,781 women, including 386 cervical, 1372 colorectal, 246 lung, and 16,777 with breast cancer, were identified. In women 18-35 years old, 11.7% underwent evaluation for fertility preservation, 13.7% underwent laboratory testing, and 6.3% pursued fertility-preserving procedures. The rates of office evaluation, laboratory testing, and performance of procedure were 3.3%, 7.5%, and 1.9 % in women aged 36-40 years and 0.5%, 7.2%, and 0.3% in those aged 41-45 years, respectively. The rate of fertility preservation evaluation rose from 1.0% in 2009 to 5.5% in 2016 (risk ratio, 4.66, 95% confidence interval, 2.38-9.11) while use of fertility-preserving procedures increased from 1.0% to 4.6% (risk ratio, 3.84, 95% confidence interval, 1.94-7.59) during the same time period. In a multivariable model, use of any fertility-preserving interventions were more common in patients with breast cancer (adjusted risk ratio, 2.30, 95% confidence interval, 1.30-4.06), those in the Northeast (adjusted risk ratio, 1.24, 95% confidence interval, 1.10-1.40), and in younger women (18-35 years) (adjusted risk ratio, 2.59, 95% confidence interval, 2.32-2.89). CONCLUSION Although limited by lack of information regarding cancer stage and desire for future fertility, only a small fraction of reproductive-aged female cancer patients receiving chemotherapy are evaluated in a nationwide sample for fertility preservation or undergo fertility-preserving procedures.

Abstract
Many infertility specialists support the existence of a relationship between the levels of mitochondrial DNA and the quality of the blastocysts. Despite the extensive use of pre-implantation genetic testing for aneuploidy, a significant percentage of euploid embryos do not implant even though the endometrium is normal. Mitochondrial DNA may be used as a new test in evaluating embryonic vitality.Ovarian aging leads to a decrease in the quantity and quality of oocytes and aged oocytes have a reduced number of mitochondria. Mitochondria are the energy factories of the cells and their lacked could leads to lower fertilization rates and poor embryonic development. Various strategies have been tested to increase the mitochondria quantity and thus improve the quality of oocytes used in in vitro fertilization. Results of ovarian rejuvenation techniques such as autologous mitochondrial transplantation have been controversial. In this review, we describe the state of the art concerning the use of mitochondrial DNA and autologous mitochondrial transplantation as new possibilities to increase success in vitro fertilization.

Abstract
OBJECTIVE To assess patient experience and convenience of using progesterone vaginal ring (VR) versus vaginal gel for women requiring luteal phase support during in vitro fertilization (IVF). DESIGN Post hoc analysis of a prospective, randomized, single-blind, multicenter, phase 3 clinical trial. SETTING Twenty-two U.S. IVF centers. PATIENT(S) Women undergoing IVF (N = 1,297). INTERVENTION(S) Randomization to weekly VR or daily gel the day after egg retrieval for up to 10 weeks, with fresh embryo transfer IVF per site-specific procedures. MAIN OUTCOME MEASURE(S) Patient satisfaction questionnaire completed at final study visit. RESULT(S) In the women who were taking ≥1 dose of either VR (n = 647) or gel (n = 650), >97% reported that learning to use the formulation, remembering to take it at the correct time, and using it as prescribed was "easy" or "somewhat easy." More VR than gel users reported noninterference with daily activity (93.3% vs. 74.7%, P<.001), sexual comfort (80.3% vs. 67.8%, P<.001), and sexual desire (73.8% vs. 61.8%, P<.001), as well as not being bothered during sexual intercourse (66.9% vs. 39.2%, P<.001). More gel than VR users reported no difficulty with application (97.4% vs. 80.9%, P<.001). Among women who had previously used progesterone during IVF, more VR users than gel users preferred their currently assigned treatment to their previous treatment (91.4% vs. 83.0%, P=.03). CONCLUSION(S) Weekly progesterone VR and daily progesterone gel were easy to use, with limited impact on quality of life. Overall, the VR appeared to interfere less with daily life, social activities, and sexual activity although the gel was less difficult or stressful to apply. CLINICAL TRIAL REGISTRATION NUMBER NCT00615251.

Abstract
Sixteen artificial intelligence (AI) and machine learning (ML) approaches were reported at the 2018 annual congresses of the American Society for Reproductive Biology (9) and European Society for Human Reproduction and Embryology (7). Nearly every aspect of patient care was investigated, including sperm morphology, sperm identification, identification of empty or oocyte containing follicles, predicting embryo cell stages, predicting blastocyst formation from oocytes, assessing human blastocyst quality, predicting live birth from blastocysts, improving embryo selection, and for developing optimal IVF stimulation protocols. This represents a substantial increase in reports over 2017, where just one abstract each was reported at ASRM (AI) and ESHRE (ML). Our analysis reveals wide variability in how AI and ML methods are described (from not at all or very generic to fully describing the architectural framework) and large variability on accepted dataset sizes (from just 3 patients with 16 follicles in the smallest dataset to 661,060 images of 11,898 human embryos in one of the largest). AI and ML are clearly burgeoning methodologies in human reproduction and embryology and would benefit from early application of reporting standards.

Abstract
Oral dydrogesterone has been used for luteal phase support on an empirical basis since the early days of in vitro fertilization (IVF) treatment. Systematic comparisons of oral dydrogesterone with vaginal progesterone, so far considered to be the standard of care, started to appear in the middle 2000s. Recently, a large, randomized, double-blind, double-dummy phase III trial on the use of daily 30 mg oral dydrogesterone versus daily 600 mg micronized vaginal progesterone for LPS in IVF was published. This company-sponsored trial confirmed the efficacy findings from previous independent researchers and firmly established the noninferiority of daily 30 mg oral dydrogesterone for luteal phase support. Despite oral administration and first pass through the liver, dydrogesterone was as well tolerated as vaginal progesterone in safety analyses. Moreover, no new fetal safety concerns have arisen from that trial. Given the widespread preference of women for an oral compound, dydrogesterone may well become the new standard for luteal phase support in fresh embryo transfer IVF cycles.

Abstract
PURPOSE Advancing maternal and paternal age leads to a decrease in fertility, and hence, many infertile couples opt for assisted reproductive technologies [ART] to achieve biological parenthood. One of the key determinants of achieving a live outcome of ART, embryo quality, depends on both the quality of the oocyte and sperm that have created the embryo. Several studies have explored the effect of oocyte parameters on embryo quality, but the effects of sperm quality on the embryo have not been comprehensively evaluated. METHOD In this review, we assess the effect of various genetic factors of paternal origin on the quality and development of the embryo. RESULTS The effects of sperm aneuploidy, sperm chromatin structure, deoxyribonucleic acid [DNA] fragmentation, role of protamines and histones, sperm epigenetic profile, and Y chromosome microdeletions were explored and found to negatively affect embryo quality. CONCLUSION We propose that careful assessment of spermatozoal parameters is essential to achieve embryo development and a healthy live birth. However, the heterogeneity in test results and the different approaches of assessing a single sperm parameter highlight the need for more research and the development of standardized protocols to assess the role of sperm factors affecting embryo quality.

Abstract
Objective To evaluate the influence of seasonal variation on in vitro fertilization (IVF) outcome in a large cohort population. Methods & materials A total of 5,765 IVF cycles conducted in Sheba medical center between 2013 and 2016 were retrospectively analyzed. The treatment cycles included 4214 ovarian stimulation and ovum pick up (OPU) cycles of which 3020 resulted in fresh embryo transfer and 1551 vitrified- warmed cycles of which1400 resulted in warmed embryo transfer. Cycles were assigned to seasons according to the date of OPU for fresh embryo transfer cycles or according to the date of embryo warming for vitrified warmed embryo transfer cycles. Results There were no statistically significant differences between the calendar months or seasons concerning the number of oocytes retrieved or fertilization rate in the fresh cycles. Throughout the 4 years of the study, the monthly clinical pregnancy rate fluctuated between 18.2% and 27.9% per fresh embryo transfer (mean 23.3%) and between 17.7% and 29.4% per vitrified warmed embryo transfer (mean 23%). These fluctuations did not follow any specific seasonal pattern. Conclusions Our study did not demonstrate any significant influence of the calendar months or seasons on the clinical pregnancy rates of fresh or vitrified warmed embryo transfers. It might be speculated that the complete pharmaceutical control of the ovarian and endometrial function, as well as the homogeneous treatments, procedures and laboratory equipment used during the study period have lowered the influence of seasonal effect on IVF treatment outcome.

Abstract
INTRODUCTION AND OBJECTIVE Due to the reported efficacy of in vitro fertilization (IVF) this method of dealing with infertility is increasing being used. Experiencing IVF can be a source of psychological and emotional difficulties for couples trying to have a child. A systematic review was performed to discuss IVF as a psychological issue that impacts on the functioning of individuals, couples and families. Ebsco, Science Direct and PsycARTICLES databases were searched using the keywords: IVF fertilization, IVF psychology, infertility, and IVF consequences, using published peer reviewed articles from 2006 onwards. Studies in the English and Polish languages, peer reviewed and investigating general IVF and infertility psychological issues were included. Data was collected by the authors between June 2015-January 2016. BRIEF DESCRIPTION OF THE STATE OF KNOWLEDGE Studies indicate that partners going through IVF may not have enough support from their closest social environments. It is argued that these unsupportive social interactions affect the well-being of couples, can hinder conception, and therefore are one of the reasons for attrition from IVF, the most effective assisted reproduction method. CONCLUSIONS There is a need to conduct studies on the effect of supportive social interactions for the functioning of couples undergoing IVF.

Abstract
In January 2016, Melissa Cook, a California gestational surrogate experiencing a multiple-birth pregnancy following the in vitro fertilization (IVF) transfer of three embryos comprised of donor eggs and sperm provided by the intended father, went to the media when the intended father requested that she undergo a fetal reduction because twins were less expensive to raise than triplets. Much of the legal interest in this case to date has centered on the enforceability of surrogacy contracts. However, the Cook case also raises troubling issues about fertility treatment practices involving gestational surrogates, twin preference, and third-party reproduction medical decision-making. This paper focuses on multiple-embryo transfers in the context of US surrogacy arrangements. Offering an original analysis of data obtained from the US national-assisted reproduction registry, it examines single- and multiple-embryo transfer trends over a 12-year period (2003 to 2014). Findings reveal that recommended guidelines were followed in fewer than 42% of the cases in 2014. The paper argues that ensuring equitable medical treatment for all recipients of IVF requires the adoption of treatment guidelines tailored to, and offering protections for, specific patient groups, and that, once in place, guidelines must be robustly implemented.

Abstract
BACKGROUND The study was designed to investigate the roles of endometrial thickness (EMT) at the day of human chorionic gonadotropin (hCG) administration on pregnancy outcomes in a large patient population. METHODS This retrospective cohort study included 9,952 patients undergoing their first IVF/ICSI with autologous oocytes from January 2011 to January 2015. Patients were divided into three groups based on the EMT (group A:≤8 mm; group B: 9-14 mm and group C:≥15 mm). Live birth rate (LBR), clinical pregnancy rate (CPR), early miscarriage rate (EMR), and ectopic pregnancy rate (EPR) were analyzed. Additionally, the live birth rate was analyzed for patients with single or double gestational sacs. RESULTS Significant differences (p < 0.05) were detected in the LBRs (30.38%, 45.73% and 54.55% for groups A, B, and C, respectively), CPRs (38.57%, 55.04% and 64.32%, respectively), and EPRs (5.58%, 3.48% and 2.19%, respectively), with thicker endometrial thickness favoring all three parameters. However, no differences were found in the EMRs among the three groups (15.64%, 13.44% and 13.05%, respectively, p > 0.05). After adjusting for female age, body mass index (BMI) and endometrial pattern, the multivariate logistic regression analysis demonstrated that the associations between EMT and LBR (adjusted OR: 2.645; 95% CI 2.020-3.464; p < 0.01), CPR (adjusted OR 2.693 95% CI 2.012-3.605 p < 0.01), and EPR (adjusted OR: 0.298 95% CI 0.101-0.713; p < 0.05) were significant. Additionally, live birth rates in the double gestational sac group were different (p < 0.05) among patients with different EMT (72.73%, 87.28%, and 87.36%, respectively), whereas no difference was found in the single gestational sac group. In the double gestational sac group, LBR was positively correlated with increasing endometrial thickness only in patients with twin pregnancies but not in patients with singletons. CONCLUSIONS Our study shows that endometrial thickness at the day of hCG administration has an effect on LBR, CPR and EPR, with all three parameters increasing with the EMT. Furthermore, successful twin pregnancies are associated with a thicker endometrium.

Zhao J, Xu B, Zhang Q, Li YP. Which one has a better obstetric and perinatal outcome in singleton pregnancy, IVF/ICSI or FET?: a systematic review and meta-analysis. Reprod Biol Endocrinol 2016; 14:51. [PMID: 27577996 PMCID: PMC5006501 DOI: 10.1186/s12958-016-0188-3] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2016] [Accepted: 08/23/2016] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND The present study aims to compare which one has a better obstetric and perinatal outcome in singleton pregnancy, frozen embryo transfer (FET) or. in vitro fertilization treatment/intracytoplasmic sperm injection (IVF/ICSI)? METHODS MEDLINE, Google Scholar and the Cochrane Library were searched for the obstetric and perinatal outcomes in singleton pregnancy after assisted reproductive technology (ART) from inception until July 2016. Clinical trials, which compared obstetric/perinatal outcomes in singleton pregnancy after FET and IVF/ICSI-ET, were included. The primary outcome was low birth weight, preterm birth, perinatal mortality, still birth, and cesarean section. RESULTS Thirteen cohort studies with 126,911 women were included, of which 12, 11, 6, 6, 5 studies were used to analyze low birth weight, preterm birth, perinatal mortality, still birth, and cesarean section, respectively. IVF/ICSI is associated with a high risk of preterm birth (OR = 1.14, 95 % CI: 1.02, 1.28) and low birth rate (OR = 1.48, 95 % CI: 1.37, 1.60). There was no significant difference in the risk of the still birth (OR = 1.01, 95 % CI: 0.76, 1.35) and perinatal mortality (OR = 1.11, 95 % CI: 0.85, 1.46) between FET and IVF/ICSI. Singleton pregnancy after FET was associated with higher cesarean section rate compared with IVF/ICSI (OR = 0.85, 95 % CI: 0.80, 0.91). CONCLUSIONS Singleton pregnancy after FET seems to have a better perinatal outcome compared with that after IVF/ICSI. Further randomized controlled trials which adjust for a variety of meaningful confounders are needed in order to draw sound conclusions.

Factors associated with the use of elective single-embryo transfer and pregnancy outcomes in the United States, 2004-2012. Fertil Steril 2016; 106:80-89. [PMID: 26997248 DOI: 10.1016/j.fertnstert.2016.02.034] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2015] [Revised: 02/09/2016] [Accepted: 02/25/2016] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To evaluate factors associated with elective single-embryo transfer (eSET) utilization and its effect on assisted reproductive technology outcomes in the United States. DESIGN Historical cohort. SETTING Not applicable. PATIENT(S) Fresh IVF cycles of women aged 18-37 years using autologous oocytes with either one (SET) or two (double-embryo transfer [DET]) embryos transferred and reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System between 2004 and 2012. Cycles were categorized into four groups with ([+]) or without ([-]) supernumerary embryos cryopreserved. The SET group with embryos cryopreserved was designated as eSET. INTERVENTION(S) None. MAIN OUTCOMES MEASURE(S) The likelihood of eSET utilization, live birth, and singleton non-low birth weight term live birth, modeled using logistic regression. Presented as adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULT(S) The study included 263,375 cycles (21,917 SET[-]cryopreservation, 20,996 SET[+]cryopreservation, 103,371 DET[-]cryopreservation, and 117,091 DET[+]cryopreservation). The utilization of eSET (SET[+]cryopreservation) increased from 1.8% in 2004 to 14.9% in 2012 (aOR 7.66, 95% CI 6.87-8.53) and was more likely with assisted reproductive technology insurance coverage (aOR 1.60, 95% CI 1.54-1.66), Asian race (aOR 1.26, 95% CI 1.20-1.33), uterine factor diagnosis (aOR 1.48, 95% CI 1.37-1.59), retrieval of ≥16 oocytes (aOR 2.85, 95% CI 2.55-3.19), and the transfer of day 5-6 embryos (aOR 4.23, 95% CI 4.06-4.40); eSET was less likely in women aged 35-37 years (aOR 0.76, 95% CI 0.73-0.80). Compared with DET cycles, the likelihood of the ideal outcome, term non-low birth weight singleton live birth, was increased 45%-52% with eSET. CONCLUSION(S) Expanding insurance coverage for IVF would facilitate the broader use of eSET and may reduce the morbidity and healthcare costs associated with multiple pregnancies.

Abstract
OBJECTIVE To evaluate risks for adverse pregnancy outcomes by number of embryos transferred (ET) and fetal heartbeats (FHB) in assisted reproductive technology-conceived singleton live births. DESIGN Longitudinal cohort using cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System between 2004 and 2008 among women who were treated and gave birth in Massachusetts. SETTING Not applicable. PATIENT(S) Assisted reproductive technology data on 6,073 births between 2004 and 2008 were linked to vital records and hospital data. Likelihood of ET ≥3 vs. 1-2, FHB >1 vs. 1, and risks of preterm birth (PTB, <37 weeks' gestation), low birth weight (LBW, <2,500 g), and small-for-gestational-age birth weight (SGA, <10th percentile) with FHB >1 were modeled with binary logistic regression using a backward-stepping algorithm, and presented as adjusted odds ratios (95% confidence intervals). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) ET ≥3, FHB >1, PTB, LBW, and SGA. RESULT(S) Higher ET was significantly more likely with older maternal age, intracytoplasmic sperm injection, assisted hatching, cleavage-stage embryos, and thawed embryos. The likelihood of FHB >1 with ≥3 ET vs. 1-2 ET was 2.04 (1.68-2.48). Risks of PTB and LBW with FHB >1 were 1.63 (1.27-2.09) and 1.81 (1.36-2.39), respectively; the risk of SGA was not significant. Nulliparity was associated with higher risks of PTB (1.34 [1.12-1.59]), LBW (1.48 [1.20-1.83]), and SGA (2.17 [1.69-2.78]). CONCLUSION(S) Number of embryos transferred was strongly associated with FHBs, with twice the risk of FHB >1 with ≥3 ET vs. 1-2 ET. Increasing FHBs were associated with significantly greater risks for PTB and LBW outcomes.

Abstract
INTRODUCTION Assisted reproduction techniques are the frequent treatment of infertility. Despite the advances in science and technology, the management of poor responder patients is still considered as one of the most urgent problems. The lack of unified definition makes the management of the poor responder patients very difficult. The aim of this review is to examine and compare the different studies done about the problem of poor responder patients. METHODS On an online research of MEDLINE/PUBMED, we found several studies on pharmacological treatment for poor responders' patients. RESULTS Our review shows that in the years numerous therapies for the management of these patients who do not respond to ovarian stimulation have been evaluated and studied, but the main problem is the large and still not well-defined meaning of poor responder women. CONCLUSION The management of the poor responder patients is very difficult. Currently, there is no any standard treatment for poor responder patients. Considering the importance of the problem, it is important to identify a diagnostic and therapeutic target. Our review shows that there are many studies with different therapeutic approaches which deserve further in-depth study to standardize diagnostic and therapeutic target.

Abstract
In vitro maturation (IVM) and in vitro fertilization (IVF) technologies are facing with growing demands of older women to conceive. Although ovarian stem cells (OSCs) of older women are capable of producing in vitro fresh oocyte-like cells (OLCs), such cells cannot respond to IVM and IVF due to the lack of granulosa cells required for their maturation. Follicular renewal is also dependent on support of circulating blood mononuclear cells. They induce intermediary stages of meiosis (metaphase I chromosomal duplication and crossover, anaphase, telophase, and cytokinesis) in newly emerging ovarian germ cells, as for the first time demonstrated here, induce formation of granulosa cells, and stimulate follicular growth and development. A pretreatment of OSC culture with mononuclear cells collected from blood of a young healthy fertile woman may cause differentiation of bipotential OSCs into both developing germ and granulosa cells. A small blood volume replacement may enable treatment of ovarian infertility in vivo. The transferred mononuclear cells may temporarily rejuvenate virtually all tissues, including improvement of the function of endocrine tissues. Formation of new follicles and their development may be sufficient for IVM and IVF. The novel proposed in vitro approaches may be used as a second possibility. Infertility of human males affects almost a half of the infertility cases worldwide. Small blood volume replacement from young healthy fertile men may also be easy approach for the improvement of sperm quality in older or other affected men. In addition, body rejuvenation by small blood volume replacement from young healthy individuals of the same sex could represent a decline of in vitro methodology in favor of in vivo treatment for human functional diseases. Here we propose for the first time that blood mononuclear cells are essential for rejuvenation of those tissues, where immune system components participate in an appropriate division and differentiation of tissue stem cells. If needed, small blood volume replacement from distinct young healthy individuals could be utilized in six month intervals for repair of young altered or aged reproductive and other tissue functions. Systemic and local use of honey bee propolis tincture is an alternative option for functional rejuvenation of some tissues.

Abstract
Genome editing technology, including zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeat (CRISPR)/Cas, has enabled far more efficient genetic engineering even in non-human primates. This biotechnology is more likely to develop into medicine for preventing a genetic disease if corrective genome editing is integrated into assisted reproductive technology, represented by in vitro fertilization. Although rapid advances in genome editing are expected to make germline gene correction feasible in a clinical setting, there are many issues that still need to be addressed before this could occur. We herein examine current status of genome editing in mammalian embryonic stem cells and zygotes and discuss potential issues in the international regulatory landscape regarding human germline gene modification. Moreover, we address some ethical and social issues that would be raised when each country considers whether genome editing-mediated germline gene correction for preventive medicine should be permitted.
