Abstract
PURPOSE To evaluate the influence of the endometrial receptivity array (ERA) test on the implantation rate (IR) and pregnancy rate (PR) in patients with previous failed euploid embryo transfers (Euploid-ET) or oocyte donation embryo transfers (Donor-ET). METHODS Single-center retrospective study of patients with ≥ 1 previous failed Euploi-ET (n = 24) or ≥ 2 failed Donor-ET (n = 32) who underwent an ERA test and a post-ERA Euploid-ET/Donor-ET between 2012 and 2018. Controls were patients with ≥ 1 previously failed Euploid-ET (n = 119) or ≥ 2 failed Donor-ET (n = 158) who underwent Euploid-ET/Donor-ET during the same period without performing an ERA test. Only blastocyst stage embryos were included. IR/PR was compared between the post-ERA ET and the last ET in the control group. RESULTS There was no statistically significant difference regarding IR [55.6% (34.6-76.5%) vs. 65.0% (56.9-73.1%)] nor PR (58.3% vs.70.6%, p = 0.238) in the Euploid-ET ERA vs. Euploid-ET control groups. In the Donor-ET arm, both IR [26.8% (12.3-41.4%) vs. 57.2% (50.1-64.3%)] and PR (34.4% vs. 65.2%, p = 0.001) were significantly lower in the ERA group. Multivariate analysis confirmed that performing an ERA test did not influence the PR in the Euploid-ET arm and was associated with a diminished PR in the Donor-ET arm. In the ERA group, 41.1% patients were non-receptive (NR). No significant difference was found regarding IR/PR in NR vs. receptive patients in both Euploid-ET/Donor-ET arms. CONCLUSIONS In our sample, the performance of an ERA test did not improve pregnancy outcomes. Future prospective studies in larger samples are needed to confirm the role of the ERA test in Euploid-ET/Donor-ET.

Abstract
STUDY QUESTION Is there any relationship between the number of oocytes retrieved and cumulative live birth rates (CLBRs) in women of advanced age? SUMMARY ANSWER CLBRs increase with the number of oocytes retrieved in women of advanced reproductive age up to 41 years old, the added value is minimal in women more than 41 years and futile in women 44 years or older. WHAT IS KNOWN ALREADY CLBR is actually the most relevant outcome of IVF from patients' perspective. There are several studies that have analysed CLBR's but some of them have included several stimulation cycles, others have not included the frozen embryo transfers (FETs) in their analysis and none has focused on women of advanced reproductive age. We aimed to assess CLBR in women ≥38 years after a single stimulation cycle plus the subsequent frozen embryo transfers. STUDY DESIGN, SIZE, DURATION This is a retrospective analysis carried out in a University-affiliated tertiary centre between January 2000 and December 2013. Overall, 4570 infertile women aged ≥38 years who underwent their first cycle in our centre were included. PARTICIPANT/MATERIALS, SETTING, METHODS Patients were categorized in four age-groups: 38-39 years (G1 = 1875 cycles), 40-41 years (G2 = 1380 cycles), 42-43 years (G3 = 833 cycles) and ≥44 years (G4 = 482 cycles). CLBR's were evaluated by adding the pregnancies and live births achieved in the FET's to the ones obtained in the fresh cycle. In order to find out the actual effect of the number of oocytes retrieved in these patients, a predictive model of CLBR according to age and oocyte yield was built. MAIN RESULTS AND THE ROLE OF CHANCE CLBRs significantly decrease with increasing age among women ≥38 years of age, with the most prominent and clinically relevant decline observed at 42-43 years old, and clear evidence for futility in women aged ≥44 years (25.9% at 38-39 years, 16.4% at 40-41 years, 7% at 42-43 years and 1.2% from 44 years onwards). The higher the number of oocytes retrieved, the higher the CLBR; however, this is more evident up to 41 years old and no clear benefit is observed from 44 years and beyond. LIMITATIONS, REASONS FOR CAUTION Limitations are related to the retrospective nature of the study; however, no significant differences were observed in the treatment protocols used. Other potential limitations could be the fact that embryo cryopreservation was carried out with slow freezing in 80% of cases and that a small proportion of patients still have frozen embryos; nevertheless, we do not expect a relevant impact of these issues as slow freezing showed excellent results that did not differ significantly compared to vitrification and, on the other hand, the extra benefit coming from the FETs was very limited. WIDER IMPLICATIONS OF THE FINDINGS The number of oocytes retrieved is significantly associated with CLBR also in women of advanced reproductive age. However, the added benefit appears to be restricted mainly in women up to 41 years old. Women over 43 do not experience any benefit in CLBR irrespective of the number of oocytes retrieved, and thus should be discouraged from doing an IVF cycle with their own oocytes; for the other age-groups, recommendations should be given considering the age and the expected ovarian response. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER NA.

Abstract
PURPOSE Hydroxypropyl cellulose (HPC), a polysaccharide that forms a viscous gel under low temperatures, is a promising substitute of the blood-derived macromolecules traditionally used in cryopreservation solutions. The performance of a protein-free, fully synthetic set of vitrification and warming solutions was assessed in a matched pair analysis with donor oocytes. METHODS A prospective study including 219 donor MII oocytes was carried out, comparing the laboratory outcomes of oocytes vitrified with HPC-based solutions and their fresh counterparts. The primary performance endpoint was the fertilization rate. Secondary parameters assessed were embryo quality on days 2 and 3. RESULTS 70/73 (95.9%) vitrified MII oocytes exhibited morphologic survival 2 h post-warming, with 49 (70.0%) presented normal fertilization, compared to 105 of 146 (71.9%) MII fresh oocytes. Similar embryo quality was observed in both groups. A total of 18 embryos implanted, out of 38 embryos transferred (47.3%), resulting in 13 newborns.

Abstract
OBJECTIVES In France, egg donation is covered by Social insurance among women<43 years old. Because of shortage of egg donor, women aged 43 years or more cannot resort to egg donation in French infertility centers, leading them to turn to the foreign centers having practices different and less regulated than in France. We are thus brought to take care of the pregnancy and of the delivery of these women. Our objective was to estimate if the perinatal risks are more important after egg donation abroad than in case of egg donation in a French center. MATERIAL AND METHODS Retrospective study between January, 2010 and April, 2013, comparing women having had an egg donation to Cochin then having delivered in the maternity hospital of their choice (n=88) and the women having had an egg donation abroad then having delivered in the Port-Royal maternity (n=121). First, the modalities of egg donation were compared between the Cochin hospital and the foreign centers. Second, the obstetric and perinatal outcomes were compared between both groups, then by stratifying according to the type of pregnancy (singleton or multiple). RESULTS Among women having had an egg donation abroad, the age of the donor was lower (25.7 vs. 31.7, P=0.001), the average number of embryos transferred higher (2.1±0.6 vs. 1.7±0.5, P=0.001) and the rate of multiple pregnancies higher (47.9% vs. 9.1%, P=0.001) than among women having had an egg donation at Cochin. We observed after egg donation abroad compared to egg donation at Cochin, a birth weight significantly lower (2678±745g vs. 3045±682g, P=0.001) and a prevalence of intrauterine growth retardation higher (11.1% vs. 4.2%, P=0.04). Among singletons, abnormal placentation was more frequent in case of egg donation abroad (17.5% vs. 5.1%, P=0.02). In case of twin pregnancy, we highlighted very high rates of complications, without significant difference according to the place where egg donation was practiced. CONCLUSION We observed an increased risk of intrauterine growth retardation after egg donation abroad, which could essentially be explained by the association between advanced maternal age and multiple gestation. For other obstetric and perinatal complications, the differences between both groups were less important than expected, but very high in both groups, whether the egg donation was realized in France or abroad. The complications seem mainly due to the multiple gestations, justifying the transfer of a single embryo whenever possible.

Abstract
The aim of this study is to describe obstetric and perinatal complications in pregnancies from oocyte donation (OD) cycles, delivering in our centre and to determine the impact of maternal age. Retrospective observational study of a 225 singleton pregnancies, 113 multiple pregnancies and 447 live birth. Pearson's χ(2) test or Fisher's exact test were used for the statistical analysis. A higher incidence of obstetric complications was observed in multiple compared to singleton pregnancies with regard to preeclampsia (24.8% versus 8%), premature rupture of membranes (9.7% versus 1.8%), preterm delivery at <37 weeks (54.9% versus 10.2%) and caesarean section (81.4% versus 64%) (p < 0.05). If the age factor is added, the caesarean sections are higher in the single pregnancy group aged ≥40 years than in the group of <40 years (73.5% versus 49.4%) (p < 0.05). A higher incidence is found in multiple versus singleton pregnancies for low birth weight (<2500 g) (61.1% versus 8.2%), admissions to the intensive care unit (15.2% versus 4.7%) and perinatal mortality (13.5‰ versus 0‰) (p < 0.05). It is necessary to consider preconception counselling prior to an OD cycle to inform patients about the incidence complications observed and recommend to transfer only a single embryo.

Abstract
Multiple pregnancies involve high obstetric and perinatal risks. The aim of this study is to evaluate, in a pilot randomized control study, if the cumulative pregnancy and live birth rates of elective single embryo transfer (eSET) are comparable to the ones obtained with elective double embryo transfer (eDET). A total of 65 patients with at least two good quality embryos was randomized, 34 (52.3%) assigned to the eSET group and 31 (47.7%) to the eDET group. The cumulative pregnancy rates (eSET: 73.5% and eDET: 77.4%. RR: 0.95 95% CI: 0.72-1.25) and live birth rates (eSET: 58.8% and eDET: 61.3%. RR: 0.96 95% CI: 0.64-1.42) were similar in the two groups. The twin pregnancy rate in the fresh transfers of eDET group was 47.7% and 0% in the eSET group. The medical team decided to interrupt the study for reasons related to risks associated with elevated twin pregnancy rate, leaving low numbers of patients within the study as a result. When considering cumulative success rates, eSET and eDET are similar in terms of efficacy. However, eDET involves an increased and unacceptable twin pregnancy rate. The only prevention strategy is single embryo transfer.

Abstract
In recent decades, the Western world has been experiencing a societal trend to prioritize the professional careers of women who postpone motherhood to about 40 years of age, when, unfortunately, natural reproductive potential declines. This is the reason why these women increasingly find it necessary to resort to oocyte donation to have a child. Thanks to the young age of the donors, the efficacy of oocyte donation is the highest of all assisted reproduction treatments and pregnancy rates achieved with this technique exceed 50%. Moreover, the large registries from ESHRE and ASRM show live birth rates close to this figure. However, there are patients who experience repeated failures in several oocyte-donation cycles, and so far oocyte-donation repeated implantation failure has not been clearly defined. This study analysed the results obtained from 2531 oocyte-donation cycles carried out in 1990 patients and defines oocyte-donation repeated implantation failure as failure to implant with more than two embryo transfers and more than four high-grade embryos transferred. This study observed this condition in 140 oocyte recipients (7%). Also, oocyte cohort size, uterine factors and systemic thrombophilias as important aetiological factors were identified were to offer new therapeutic strategies to patients.

Abstract
To compare cumulative pregnancy and live birth rates of single embryo transfer (SET) vs. double embryo transfer (DET) in women <35 years old with good-quality embryos, we designed an observational prospective study carried out between October 2002 and December 2006. Patients who accepted SET were compared with those who decided DET. A total of 628 couples who underwent embryo transfers met the criteria for SET: 52% accepted it, while 47.8% asked for DET. Implantation rate was higher in SET, 46.6% (p < 0.05), whereas pregnancy rate (PR) per transfer was higher in DET, 38.3% (p < 0.05). Twin PR in DET was 26.4% compared with 0.7% in SET (p < 0.05). SET group performed 278 frozen embryo transfer and DET 128. The mean of embryos transferred was the same, resulting in similar pregnancy and twin PR (SET: 24.8% and 21.7% vs. DET: 25.0% and 28.1%). Cumulative PR was 66.2% in SET and 69.7% in DET, not showing significant differences (NS). Likewise, cumulative live birth rates did not show differences. Cumulative twin PR in SET was 7.2% and in DET 26.6%, (p < 0.05). Cumulative PR over time leveled at 15-18 months follow-up in both groups. In Conclusion, in order to reduce twins we support the promotion of SET.
