Abstract Study question How do live birth rates differ in anovulatory women with polycystic ovary syndrome and hypothalamic hypogonadism compared to normo-ovulatory women undergoing fresh or frozen embryo transfer? Summary answer Live birth rates are similar among all groups undergoing fresh embryo transfer but are significantly lower in women with hypothalamic hypogonadism undergoing frozen embryo transfer. What is known already Conflicting data exist regarding pregnancy outcomes in patients with tubal factor infertility versus polycystic ovary syndrome (PCOS). Some studies demonstrate higher pregnancy and live birth rates for women with PCOS undergoing fresh embryo transfer, but other studies demonstrate no difference. Women with PCOS have higher live birth rates than those with tubal factor infertility when undergoing frozen embryo transfer. Fewer data are available regarding IVF outcomes in women with hypothalamic hypogonadism (HH) and tubal factor infertility. Several studies report comparable live birth rates with fresh embryo transfer, but there are no data on frozen embryo transfer outcomes. Study design, size, duration Retrospective cohort study of all fresh and frozen autologous embryo transfers performed for patients with oligo-anovulation (PCOS, n = 380 and HH, n = 39) and normo-ovulation (tubal factor infertility, n = 315) from 1/1/2012 to 6/30/2019. A total of 734 transfers from 653 patients were analyzed. Participants/materials, setting, methods Transfer outcomes, including implantation, miscarriage, clinical pregnancy and live birth rates, were assessed in fresh and frozen embryo transfer cycles. Adjusted relative risks (RR) and 95% confidence intervals (CI) were calculated adjusting for age, BMI, stimulation protocol, number of embryos transferred, embryo quality, endometrial stripe thickness and day of transfer. Poisson regression was used for counts and with an offset for ratios. Generalized estimating equations were used to account for patients contributing multiple cycles. Main results and the role of chance For fresh embryo transfer cycles, live birth rates are similar among patients with tubal factor infertility, PCOS and HH (29.5% vs. 37.9% vs. 35.9%, respectively, aRR 1.15 95% CI: 0.91–1.44 and aRR 1.23 95% CI: 0.81–2.00, respectively). When evaluating frozen embryo transfer cycles, patients with HH have lower live birth rates than patients with tubal factor infertility (26.5% vs. 42.6%, aRR 0.54 95% CI: 0.33–0.88) and patients with PCOS (26.5% vs. 46.7%, aRR 0.55 95% CI: 0.34–0.88). Additionally, patients with HH have higher chemical pregnancy rates and miscarriage rates than patients with tubal factor infertility (26.5% vs. 13.0% and 17.7% vs. 6.5%, respectively, RR 2.71 95% CI: 1.27–5.77 and RR 2.03 95% CI: 1.05–3.80, respectively). Point biserial correlation showed no significant correlation between live birth and endometrial stripe thickness in HH patients undergoing frozen embryo transfer (r = 0.028, p-value 0.876). Limitations, reasons for caution This study is limited by its retrospective nature and the small sample size of women with hypothalamic hypogonadism. Additionally, these data represent outcomes from a single academic center, so generalizability of our findings may be limited. Wider implications of the findings: Lower live birth rates for HH patients undergoing frozen embryo transfer cycles are not correlated with endometrial stripe thickness. This may be due to absent gonadotropin signaling on endometrial receptors. A prospective randomized trial of HH patients to modified natural versus programmed frozen embryo transfer would best support this hypothesis. Trial registration number Not applicable

Background Conflicting evidence still prevails concerning the effect of preovulatory elevated progesterone (EP4) on reproductive outcomes in fresh embryo transfer (ET). However, few studies have analyzed the effect of EP4 on the likelihood of pregnancy using multivariate regression approach. The potential confounding factors tested in these studies were limited to either patient’s characteristics or to stimulation related parameters. Yet, several studies have shown that postovulatory parameters such as midluteal progesterone (P4) level may be considered as a proxy variable of endometrial receptivity as well. Objective The aim of the present study was to estimate the independent effect of preovulatory P4 effect, if any, on the probability of live birth (LB) by considering the midluteal endocrine profile when controlling for the potential confounding factors. Methods This is a secondary data analysis of a cohort of fresh IVF/ICSI cycles triggered with GnRH agonist (n = 328) performed in a single IVF center during the period 2014–2016. Patients contributed only one cycle and were stratified into four groups according to preovulatory P4 quartiles. We assessed the association between preovulatory P4 and the odds of LB calculated by logistic regression analysis after controlling for the most clinically relevant confounders. The primary outcome measure: Live birth rates (LBR). Results Both preovulatory and midluteal P4 were significantly correlated with the ovarian response. Logistic regression analysis showed that preovulatory serum P4 did not have a significant impact on LBR. In contrast, midluteal serum P4 level was an important independent factor associated with LBR. The optimal chance of LBR was achieved with midluteal serum P4 levels of 41–60 ng/ml, [OR: 2.73 (1.29–5.78); p< 0.008]. Conclusion The multivariate analysis suggests that the midluteal P4 level seems to impact LBR more than the preovulatory P4 level in women undergoing IVF treatment followed by fresh ET.

Improvements in human IVF have led to increased pregnancy rates but at the expense of increasing twinning rates. Twins are a bad outcome for the offspring, parents and the healthcare system. An obvious solution to this is to transfer only one embryo and freeze the rest for potential further treatment. This study looked at the effect of doing this on the cumulative live birth rate (when the cryopreserved embryos were thawed and transferred). Patients less than 38 years of age presenting for IVF treatment and with more than two embryos suitable for transfer were offered the chance of transferring only one embryo (elective single embryo transfer, eSET) and freezing the rest. Those patients declining a single embryo transfer had two transferred and served as the controls. Patients not achieving a pregnancy returned for a frozen embryo transfer but were not restricted on the number transferred (to a maximum of two). Cumulative live birth rates were recorded over the ensuing two years. Statistical comparisons were made using paired chi-square tests. The live birth rates from the initial fresh transfer was 41% for eSET (41/111) and significantly higher (53%, P&lt;0.05) for the two-embryo transfer group. These differences were eliminated when the frozen embryos were factored in, both groups rising to 61% of patients treated (68 and 172 live births, respectively). The twinning rate was significantly reduced (P&lt;0.01) from 33% in the two-embryo transfer group to 6% (arising from 4 sets of twins in the frozen embryo transfers) in the eSET group. eSET in the fresh embryo transfer cycle does not affect the chances of a live birth and reduces the twinning rate at least fivefold. Currently, 70% of patients under the age of 38 are electing to have eSET.

Summary This study analyzed the effects of the day of trophectoderm (TE) biopsy and blastocyst grade on clinical and neonatal outcomes. The results showed that the implantation and live birth rates of day 5 (D5) TE biopsy were significantly higher compared with those of D6 TE biopsy. The miscarriage rate of the former was lower than that of the latter, but there was no statistically significant difference. Higher quality blastocysts can achieve better implantation and live birth rates. Among good quality blastocysts, the implantation and live birth rates of D5 and D6 TE biopsy were not significantly different. Among fair quality and poor quality blastocysts, the implantation and live birth rates of D5 TE biopsy were significantly higher compared with those of D6 TE biopsy. Neither blastocyst grade nor the day of TE biopsy significantly affected the miscarriage rate. Neonatal outcomes, including newborn sex, gestational age, preterm birth, birth weight and low birth weight in the D5 and D6 TE biopsies were not significantly different. Both blastocyst grade and the day of TE biopsy must be considered at the same time when performing preimplantation genetic testing–frozen embryo transfer.

Abstract Study question The purpose of this systematic review is to calculate dropout-rates of IVF/ICSI treatment by analysing the published cumulative live birth rates of IVF/ICSI treatment. Summary answer One out of three patients stop their treatment after their first IVF/ICSI cycle and dropout-rates tend to increase per consecutive cycle. What is known already Cumulative live birth rates (CLBRs) have created the possibility to present realistic probabilities of having a live birth after IVF/ICSI treatment. However, it is noted that a significant percentage of the patients stop their treatment before having a child (“dropout”). Possible reasons and predicting factors for dropout of treatment are already extensively investigated. However, only a few studies try to report about the incidence of dropout. Publications on CLBRs of large numbers of patients allow the extraction of dropout-rates. These rates will provide insight in the extent of the problem and could be used as a reference for interventional studies. Study design, size, duration Four databases (PubMed, The Cochrane Library, EMBASE, DoKS) were systematically searched from 1992 to December 2020. Search terms referred to “cumulative live birth” AND “ART/IVF/ICSI”. No restrictions were made on the type or language of publication. Studies were included if they reported absolute numbers of patients and live births per consecutive complete IVF/ICSI cycle or per consecutive embryo transfer cycle, starting from the first IVF/ICSI cycle for each patient. Participants/materials, setting, methods Dropout-rates per cycle were calculated in two manners: “intrinsic dropout-rate” with all patients that started the particular IVF/ICSI cycle in the denominator, and “potential dropout-rate” with all patients who did not achieve a live birth after IVF/ICSI (and potentially could have started a consecutive cycle) in the denominator. Dropout-rates were analysed for consecutive complete cycles and consecutive embryo transfer cycles, because these two manners are used in reporting CLBRs, often related to the reimbursement policy. Main results and the role of chance This review included 29 studies and almost 800,000 patients from different countries and registries. Regarding the patients who started their first IVF/ICSI cycle, trying to conceive their first child by IVF/ICSI, intrinsic dropout-rate was 33% (weighted average) after the first complete cycle, meaning they did not return for their second oocyte retrieval cycle. After the first embryo transfer cycle, intrinsic dropout-rate was 27% (weighted average), meaning those patients did not return for their next frozen-thawed embryo transfer cycle or for the next oocyte retrieval cycle. Regarding the patients who did not achieve a live birth after the first complete cycle, potential dropout-rate was 48% (weighted average), and 37% (weighted average) after the first embryo transfer cycle. Both potential and intrinsic dropout-rates for both consecutive complete and embryo transfer cycles tended to increase with cycle number. One study on second IVF/ICSI conceived children showed a potential dropout-rate after the first complete cycle of 29%. From studies on women &gt;40 years of age, the potential dropout-rate after the first complete cycle was 45% (weighted average) and from studies with the uses of testicular sperm extraction, the potential dropout-rate after the first complete cycle was 34% (weighted average). Limitations, reasons for caution Our analysis was hampered by the different ways of reporting on CLBRs (complete cycles versus embryo transfer cycles), informative censoring, patients changing clinics and spontaneous pregnancies. Dropout-rates were potentially overestimated given that spontaneous pregnancies were not taken into account. Wider implications of the findings: The extent of dropout in IVF/ICSI treatment is substantial and has an important impact on its effectiveness. Therefore, it is a challenge for fertility centers to try to keep patients longer on board, by taking into account the patients’ preferences and managing their expectations.
