Poor Ovarian Responders

The paper analyzes the literature data on the use of the growth hormone (GH) in ovarian stimulation in assisted reproductive technologies (ART). Routine use of GH in ovarian stimulation in patients with a normal GH level does not increase pregnancy and childbirth rates in ART. Also, no benefits of using GH have been identified for patients with polycystic ovary syndrome, despite the increase in insulin and IGF-1 blood levels. The main research focus is to study the use of GH in patients with poor ovarian response. According to the meta-analysis conducted by X.-L. Li et al. (2017), GH in ovarian stimulation of poor ovarian responders increases the number of received oocytes, mature oocytes number, reduces the embryo transfer cancellation rate and does not affect the fertilization rate. The pregnancy and live birth rates are significantly higher in the group of GH use - by 1.65 (95% CI 1.23-2.22) and 1.73 (95% CI 1.25-2.40) times, respectively. Thus, it is advisable to use GH in ovarian stimulation in poor ovarian responders, since it allows to increases live birth rate in ART. However, further studies should determine the optimal GH dose and assesse it`s safety in ART programs.

Abstract BackgroundAbnormal reproductive tract flora may cause infertility, and it may play a key role in the success of assisted reproductive technologies (ART). The obvious short-term changes in estrogen caused by clinical protocols with IVF-ET provide a unique perspective for us to assess the vaginal flora, shifting hormonal condition and investigate the potential associations of the vaginal micro-ecology with cycle outcome of pregnancy. The Vaginal Micro-ecology Evaluation System (VMES) as a tool to analyze the vaginal microbiomes in most areas of China. This study aims to apply the VMES to evaluate the dynamics of vaginal micro-ecology during IVF-ET, and investigate the correlations between vaginal micro-ecology with pregnancy outcome.Methods　150 patients were enrolled who underwent early follicular phase prolonged protocol IVF-ET due to tubal factors. The VMES is used to evaluate vaginal microbiology indicators of vaginal swabs obtained in different hormonal milieu during the IVF-ET cycle. The pregnancy outcomes were observed, if pregnant.Results　In our data, the prevalence of bacterial vaginitis (BV) accounts for 3.3%. During IVF procedure, the vaginal microbiome varied across hormonal milieu in some but not all patients. The proportion of BV, and unidentified dysbiosis were increased significantly on the day of human chorionic gonadotropin (HCG) administration. The vaginal micro-ecology on the day of HCG administration correlated with outcome (live birth / no live birth). The multivariable logistic regression model showed that the average age, the duration of infertility, and the vaginal micro-ecology after controlled ovarian hyperstimulation (COH) were associated with the live birth rate.ConclusionOur retrospective cohort study suggests that the VEMS has enabled discovery of unidentified dysbiosis shift in the vaginal micro-ecology during IVF-ET therapy. More importantly, the vaginal micro-ecology on the day of HCG administration was significantly associated with the live birth rate.

Abstract Context Supraphysiological estradiol exposure after ovarian stimulation may disrupt embryo implantation after fresh embryo transfer. Women with polycystic ovary syndrome (PCOS), who usually overrespond to ovarian stimulation, have a better live birth rate after frozen embryo transfer (FET) than after fresh embryo transfer; however, ovulatory women do not. Objective To evaluate whether the discrepancy in live birth rate after fresh embryo transfer vs FET between these two populations is due to the variation in ovarian response (i.e., peak estradiol level or oocyte number). Design, Setting, Patients, Intervention(s), and Main Outcome Measure(s) This was a secondary analysis of data from two multicenter randomized trials with similar study designs. A total of 1508 women with PCOS and 2157 ovulatory women were randomly assigned to undergo fresh or FET. The primary outcome was live birth. Results Compared with fresh embryo transfer, FET resulted in a higher live birth rate (51.9% vs 40.7%; OR, 1.57; 95% CI, 1.22 to 2.03) in PCOS women with peak estradiol level >3000pg/mL but not in those with estradiol level ≤3000 pg/mL. In women with PCOS who have ≥16 oocytes, FET yielded a higher live birth rate (54.8% vs 42.1%; OR, 1.67; 95% CI, 1.20 to 2.31), but this was not seen in those with <16 oocytes. In ovulatory women, pregnancy outcomes were similar after fresh embryo transfer and FET in all subgroups. Conclusions Supraphysiological estradiol after ovarian stimulation may adversely affect pregnancy outcomes in women with PCOS but not in ovulatory women.

Infertile Women

IntroductionPolycystic ovary syndrome (PCOS) is the first common cause of anovulatory infertility. Currently, in vitro fertilisation (IVF) is recommended when conventional attempts have failed. In vitro maturation (IVM) of human oocytes is an emerging treatment option in infertile women with PCOS. It is a patient-friendly intervention, avoiding the risk of ovarian hyperstimulation syndrome, which is a serious complication of controlled ovarian stimulation in the standard IVF procedure. We plan a randomised controlled trial (RCT) to evaluate whether IVM is non-inferior to the standard IVF for live birth in women with PCOS.Methods and analysisThis is a single-centre, open-label, non-inferiority RCT performed in a large reproductive medicine centre in China. Infertile women with PCOS will be randomised to receive either IVM or standard IVF in a 1:1 treatment ratio after informed consent. IVF procedures used in our study are all standard treatments and other standard-assisted reproductive technologies will be similar between the two groups. The primary outcome is ongoing pregnancy leading to live birth within 6 months of the first oocyte retrieval cycle after randomisation. Pregnancy outcome, maternal safety and obstetric and perinatal complications will be secondary outcomes. The planned sample size is 350 (175 per group).Ethics and disseminationEthical permission was acquired from the Ethics Committee of Peking University Third Hospital. The results will be issued to publications through scientific journals and conference reports.Trial registration numberNCT03463772.

Abstract Background: Cumulative live birth rate (CLBR) becomes a comprehensive and meaningful indictor of the success of IVF nowadays. Frozen-embryo transfer (FET) was associated with a higher rate of live birth and a lower risk of the ovarian hyperstimulation syndrome (OHSS) in polycystic ovary syndrome (PCOS) patients. Progestin-primed ovarian stimulation (PPOS) is a new ovarian stimulation protocol in which oral progestin been used to prevent premature luteinizing hormone (LH) surges during ovarian stimulation. The purpose of the current study is to investigate the CLBR of an in vitro fertilization (IVF) cycle in women with PCOS following PPOS protocol compared with gonadotropin releasing hormone (GnRH) antagonist protocol.Methods: It is a retrospective study. The first IVF cycle of 666 PCOS women were included. Ovarian stimulations were performed with PPOS or GnRH antagonist protocol. All patients included in the analysis had either delivered a baby or had used all their embryos of their first stimulated cycle. The patients were followed for 2–7 years until February 2020.Result(s): The CLBR were similar in the PPOS and GnRH antagonist group (64% vs 60.1%, P = 0.748). Logistic regression analyses showed treatment protocol (PPOS vs GnRH antagonist) did not show any significant correlation with the CLBR (adjusted OR: 0.898; 95% CI: 0.583-1.384, P=0.627). No statistically significant differences were found in the live birth rates per embryo transfer (41.3% vs. 38.4%) in the study group and controls.Conclusion(s): The results of this study showed that both the live birth rate per embryo transfer and the cumulative live birth rate were similar between PPOS and GnRH antagonist group. PPOS protocol is efficient in the controlled ovarian stimulation of patients with PCOS.

Abstract Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in women of childbearing, which is defined by the accumulation of multiple, small fluid-filled ovarian cysts without the selection of a single dominant follicle. Most PCOS phenotypes are characterized by the absence of spontaneous ovulation, resistance toward ovulation inductors, the production of a large immature oocytes number, and the high prevalence of ovarian hyperstimulation syndrome, resulting in reduced assisted reproductive technologies (ART) programs effectiveness. The review analyses current data about the relationship between polymorphism genotypes of KISS genes, follicle stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH) and their receptors genes, gonadotropin-releasing hormone (GnRH), estrogen, and progesterone receptors genes, the PCOS risk and the features of ovarian response to stimulation during ART cycles. The use of single nucleotide polymorphisms (SNPs) as prognostic markers of ART programs outcomes would provide a personalized approach to the drugs and doses choice for ovarian stimulation and significantly increase the chance of pregnancy.
