Abstract STUDY QUESTION Does late follicular-phase elevated serum progesterone (LFEP) during ovarian stimulation for oocyte donation have an impact on embryo quality (EQ) and cumulative live birth rate (CLBR)? SUMMARY ANSWER LFEP does not have an influence on EQ nor CLBR in oocyte donation cycles. WHAT IS KNOWN ALREADY Ovarian stimulation promotes the production of progesterone (P) which, when elevated during the follicular phase, has been demonstrated to have a deleterious effect in autologous fresh IVF outcomes. While there is robust evidence that this elevation results in impaired endometrial receptivity, the impact on EQ remains a matter of debate. The oocyte donation model is an excellent tool to assess the effects of LFEP on EQ from those on endometrium receptivity separately. Previous studies in oocyte donation cycles investigating the influence of elevated P on pregnancy outcomes in oocyte recipients showed conflicting results. STUDY DESIGN, SIZE, DURATION This is a retrospective analysis including all GnRH antagonist down-regulated cycles for fresh oocyte donation taking place in a tertiary referral university hospital between 2010 and 2017. A total of 397 fresh donor-recipient cycles were included. Each donor was included only once in the analysis and could be associated to a single recipient. PARTICIPANTS/MATERIALS, SETTING, METHODS The sample was stratified according to serum P levels of ≤1.5 and >1.5 ng/mL on the day of ovulation triggering. The primary endpoint of the study was the top-quality embryo rate on Day 3, and the secondary outcome measure was CLBR defined as a live-born delivery beyond 24 weeks. MAIN RESULTS AND THE ROLE OF CHANCE Three hundred ninety-seven fresh oocyte donation cycles were included in the analysis, of which 314 (79%) had a serum P ≤ 1.5 ng/mL and 83 (20.9%) had a serum P > 1.5 ng/mL. The average age of the oocyte donors was 31.4 ± 4.7 and 29.9 ± 4.5 years, respectively, for normal and elevated P (P = 0.017). The mean number of oocytes retrieved was significantly higher in the elevated P group with 16.6 ± 10.6 vs 11.5 ± 6.9 in the P ≤ 1.5 group (P < 0.001). In parallel, the total number of embryos on Day 3, as well as the number of good-quality embryos at this stage, was significantly higher in the elevated P group (6.6 ± 5.6 vs 4.15 ± 3.5 and 8.7 ± 6.3 vs 6.1 ± 4.4; respectively, P < 0.001). However, maturation and fertilization rates did not vary significantly between the two study groups and neither did the top- and good-quality embryo rate and the embryo utilization rate, all evaluated on Day 3 (P = 0.384, P = 0.405 and P = 0.645, respectively). A multivariable regression analysis accounting for P groups, age of the donor, number of retrieved oocytes and top-quality embryo rate as potential confounders showed that LFEP negatively influenced neither the top-quality embryo rate nor the CLBR. LIMITATIONS, REASONS FOR CAUTION This is an observational study based on a retrospective data analysis. Better extrapolation of the results could be validated by performing a prospective trial. Furthermore, this study was focused on oocyte donation cycles and hence the results cannot be generalized to the entire infertile population. WIDER IMPLICATIONS OF THE FINDINGS This is the first study providing evidence that LFEP does not influence CLBR and is adding strong evidence to the existing literature that LFEP does not harm EQ in oocyte donation programs.

Autologous Oocytes

The application of MACS non-apoptotic sperm selection in infertility clinics is controversial since the published literature does not agree on its effect on reproductive outcomes. Therefore, it is not part of the routine clinical practice. Classical measures of reproductive success (pregnancy or live birth rates per ovarian stimulation) introduce a bias in the evaluation of a technique’s effect, since only the best embryo is transferred. This retrospective, multicenter, observational study evaluated the impact of MACS on reproductive outcomes, measuring results in classical parameters and cumulative live birth rates (CLBR). Data from ICSI cycles using autologous oocyte in Spanish IVIRMA fertility clinics from January 2008 to February 2020 were divided into two groups according to their semen processing: standard practice (reference: 46,807 patients) versus an added MACS sperm selection (1779 patients). Only when measured as CLBR per embryo transferred and per MII oocyte used was the difference between groups statistically significant. There were no significant differences between MACS and reference groups on pregnancy and live birth rates. In conclusion, results suggest that non-apoptotic sperm selection by MACS on unselected males prior to ICSI with autologous oocytes has limited clinical impact, showing a subtle increase in CLBR per embryo transferred.

Abstract text The challenge of cryopreserve, store for prolonged period, and successfully implant the female gamete is nowadays feasible thanks to vitrification. The technology that was initially validated in oocyte recipients is currently applied to a vast population, including women at risk of losing their ovarian function due either to iatrogenic causes as occurs in cancer patients, or due to the natural depletion of the ovarian reserve as a result of age related fertility decline. That is the case of a growing population of women who wish to postpone childbearing and decide on oocyte vitrification as a means of fertility preservation (FP). At present, there is a growing body of evidence regarding the use of vitrified oocytes by many women under different indications, which makes it possible to evaluate the approach from different scenarios. So that vitrification can be evaluated in terms on survival rates, embryo development and the rate at which vitrified oocytes develop into live-born children in IVF cycles using vitrified oocytes which were initially stored due to different reasons. The effects of vitrification at the subcellular level and its impact on oocyte competence is of interest in the evaluation of the efficacy of the technology. Some studies have indicated that vitrification may affect ultrastructure, reactive oxygen species (ROS) generation, gene expression, and epigenetic status. However, it is still controversial whether oocyte vitrification could induce DNA damage in the oocytes and the resulting early embryos. Recent studies show that oocytes survival and clinical outcome after vitrification can be impaired by patients’ age and the clinical indication or the reason for vitrification. These studies show that age at oocyte retrieval strongly affects the survival and reproductive prognosis. In our experience, oocyte survival, pregnancy and cumulative live birth rates are significantly higher when patients are aged 35 years or younger versus patients older than 35 years at oocyte retrieval. Therefore, elective-FP patients should be encouraged to decide at young ages to significantly increase their chances of success. There is also evidence that the reason for vitrification is associated to the success rates. Poorer reproductive outcome was reported in cancer patients, low responders and endometriosis patients when compared to healthy women in age matching groups. Moreover, there are certain individualities linked to specific populations, as occurs when endometriosis patients had cystectomy earlier than the oocyte retrieval for FP. These women achieved lower success rates as compared to non-operated age matching counterparts. In this case, the lower cumulative live birth rates observed in operated women are, most probably, due to the smaller number of oocytes available, as a consequence of the detrimental effect of the surgery on the ovarian reserve. In this regard, several reports show that the number of oocytes available per patient is another variable closely related to the outcome in all populations using vitrified oocytes after FP. Thus, a significant improvement in the cumulative live birth rates can be achieved by adding a few oocytes, especially in healthy young patients. Different populations using vitrified oocytes under several indications achieve differential results in terms of pregnancy rates, when calculated in overall. Nonetheless, when the calculations for the cumulative probability of achieving a baby are made according the number of oocytes used per patient belonging to the same group of age, the results become comparable between different populations, as shown by the comparison between elective freezers versus endometriosis patients. Undoubtedly, vitrification can be recognized as one of the latest brakethrough in the ART field, but certainly the next step forward would be the successfull automatization of the vitrification and warming processes to achieve fully consistency among different laboratories.

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 >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.
