ABSTRACT
In recent years, the prevalence of infertility has increased, and appears to affect approximately one in six couples. Some of them must perform assisted reproductive techniques (ART) in order to achieve pregnancy. As a result, growing interest has arisen about predictive factors of pregnancy and live birth with and without ART. Anti-Mullerian hormone (AMH) is a glycoprotein discovered in the 1950s in male embryonic sexual differentiation. Later, in 1984, its role in folliculogenesis was reported: secreted by granulosa cells, this hormone is involved in the regulation of the recruitment of primordial follicles and in follicular growth. AMH assays were developed for women in 1990s, and the serum AMH level has rapidly become a crucial element in managing women's fertility. Based mainly on its ability to be a quantitative but indirect marker of ovarian reserve, the serum AMH assay is widely used in reproductive medicine and ART. This review summarizes current knowledge of the AMH assessment in the field of reproductive medicine. We focus on the role of AMH level to predict spontaneous pregnancy occurrence, ART outcomes, and fertility preservation outcomes.

OBJECTIVE: To study the fertility outcomes of women who tried to conceive after breast cancer (BC) treatment and fertility preservation. DESIGN: Retrospective observational, bicentric cohort study. SETTING: University hospital. PATIENTS: Patients with BC. INTERVENTION: All patients who had undergone fertility preservation before BC treatment between January 2013 and July 2019 were included (n = 844). The endpoint date was March 1, 2022. Patients with missing data on pregnancy attempts after a cancer diagnosis (n = 195) were excluded from the pregnancy analysis. MAIN OUTCOME MEASURES: Cumulative incidences of pregnancy and live birth (LB) were calculated. For women who became pregnant, the time to conception was calculated between the first fertility preservation consultation and the estimated day of conception. For those who did not conceive, we considered the time between the first fertility preservation consultation and the endpoint date, or the date of patient death. A Cox regression model was used to study the predictive factors for pregnancy and LB. RESULTS: Among the 649 patients with available data on pregnancy attempts after BC diagnosis, 255 (39.3% [35.5-43.2]) tried to conceive (median follow-up of 6.5 years). Overall, 135 (52.9% [46.6-59.2]) of these patients achieved a pregnancy, mainly through unassisted conception (79.3% [72.8-84.8]), and 99 reported an LB (representing 38.8% of patients who attempted conception). In our cohort, 48 months after the first fertility preservation consultation, the cumulative incidence of pregnancy was 33.1% ([27.6-37.9]). After adjustment for age, parity, type of chemotherapy administration, and endocrine therapy, only multiparity at diagnosis and absence of chemotherapy were positive predictive factors of pregnancy after cancer. Of the 793 patients who had vitrified oocytes and embryos, 68 used them (27% [21.3-32.5] of the patients who tried to conceive), resulting in 8 LBs (11.8% [5.2-21.9]). Women who used their cryopreserved oocytes and embryos were older at the first consultation of fertility preservation (hazard ratio 1.71 [1.42-2.21]), and chose more often to vitrify embryos (hazard ratio 1.76 [1.28-2.23]). CONCLUSION: Although pregnancy rates after fertility preservation for patients with BC are low, most conceptions are achieved without medical assistance. Our findings provide useful information to advise women on the different techniques of fertility preservation, their efficacy, and safety, as well as the relatively high chances of unassisted conception.
ABSTRACT
OBJECTIVE: To update the 2010 CNGOF clinical practice guidelines for the first-line management of infertile couples. MATERIALS AND METHODS: Five major themes (first-line assessment of the infertile woman, first-line assessment of the infertile man, prevention of exposure to environmental factors, initial management using ovulation induction regimens, first-line reproductive surgery) were identified, enabling 28 questions to be formulated using the Patients, Intervention, Comparison, Outcome (PICO) format. Each question was addressed by a working group that had carried out a systematic review of the literature since 2010, and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) methodology to assess the quality of the scientific data on which the recommendations were based. These recommendations were then validated during a national review by 40 national experts. RESULTS: The fertility work-up is recommended to be prescribed according to the woman's age: after one year of infertility before the age of 35 and after 6months after the age of 35. A couple's initial infertility work-up includes a single 3D ultrasound scan with antral follicle count, assessment of tubal permeability by hysterography or HyFOSy, anti-Mullerian hormone assay prior to assisted reproduction, and vaginal swabbing for vaginosis. If the 3D ultrasound is normal, hysterosonography and diagnostic hysteroscopy are not recommended as first-line procedures. Chlamydia trachomatis serology does not have the necessary performance to predict tubal patency. Post-coital testing is no longer recommended. In men, spermogram, spermocytogram and spermoculture are recommended as first-line tests. If the spermogram is normal, it is not recommended to check the spermogram. If the spermogram is abnormal, an examination by an andrologist, an ultrasound scan of the testicles and hormonal test are recommended. Based on the data in the literature, we are unable to recommend a BMI threshold for women that would contraindicate medical management of infertility. A well-balanced Mediterranean-style diet, physical activity and the cessation of smoking and cannabis are recommended for infertile couples. For fertility concern, it is recommended to limit alcohol consumption to less than 5 glasses a week. If the infertility work-up reveals no abnormalities, ovulation induction is not recommended for normo-ovulatory women. If intrauterine insemination is indicated based on an abnormal infertility work-up, gonadotropin stimulation and ovulation monitoring are recommended to avoid multiple pregnancies. If the infertility work-up reveals no abnormality, laparoscopy is probably recommended before the age of 30 to increase natural pregnancy rates. In the case of hydrosalpinx, surgical management is recommended prior to ART, with either salpingotomy or salpingectomy depending on the tubal score. It is recommended to operate on polyps>10mm, myomas 0, 1, 2 and synechiae prior to ART. The data in the literature do not allow us to systematically recommend asymptomatic uterine septa and isthmoceles as first-line surgery. CONCLUSION: Based on strong agreement between experts, we have been able to formulate updated recommendations in 28 areas concerning the initial management of infertile couples.

OBJECTIVE: To determine whether oxygen (O2) tension (20% vs. 5%) has an impact on oocyte maturation rates and morphology during in vitro maturation (IVM). DESIGN: A prospective, observational, monocentric, sibling-oocyte study. SETTING: University Hospital. PATIENTS: A total of 143 patients who underwent IVM for fertility preservation purposes from November 2016 to April 2021 were analyzed. Patients were included when ≥2 cumulus-oocyte complexes (COCs) were retrieved. The cohort of COCs obtained for each patient was randomly split into two groups: group 20% O2 and group 5% O2. INTERVENTION: Cumulus-oocyte complexes were incubated for 48 hours either under 5% O2 or 20% O2. After 24 and 48 hours of culture, every oocyte was assessed for maturity and morphology, to estimate oocyte quality. Morphology was evaluated considering six parameters (shape, size, ooplasm, perivitelline space, zona pellucida, and polar body characteristics), giving a total oocyte score ranging from -6 to +6. MAIN OUTCOME MEASURES: Maturation rates and total oocyte scores were compared using paired-sample analysis between group 20% O2 and group 5% O2. RESULTS: Patient median age was 31.4 [28.1-35.2] years-old. The mean serum antimüllerian hormone levels and antral follicle count were 3.2 ± 2.3 ng/mL and 27.2 ± 16.0 follicles, respectively. A mean of 10.7 COCs per cycle were retrieved, leading to 6.1 ± 2.4 metaphase II oocytes vitrified (total maturation rate = 57.3%; 991 metaphase II oocytes/1,728 COCs). A total of 864 COCs were included in each group. Oocyte maturation rates were not different between the two groups (group 20% O2: 56.82% vs. group 5% O2: 57.87%, respectively). Regarding oocyte morphology, the mean total oocyte score was significantly higher in group 5% O2 compared with group 20% O2 (3.44 ± 1.26 vs. 3.16 ± 1.32, P=.014). CONCLUSION: As culture under low O2 tension (5% O2) improves oocyte morphology IVM, our results suggest that culture under hypoxia should be standardized. Additional studies are warranted to assess the impact of O2 tension on oocyte maturation and the benefit of IVM under low O2 tension for embryo culture after utilization of frozen material.

STUDY QUESTION: Is serum anti-Müllerian hormone (AMH) level predictive of cumulative live birth (CLB) rate after ART or in women trying to conceive naturally? SUMMARY ANSWER: Serum AMH level is linked to CLB after IVF/ICSI but data are lacking after IUI or in women trying to conceive without ART. WHAT IS KNOWN ALREADY: Serum AMH level is a marker of ovarian reserve and a good predictor of ovarian response after controlled ovarian stimulation. It is unclear whether AMH measurement can predict CLB in spontaneous or assisted conception. STUDY DESIGN, SIZE, DURATION: A systematic review and meta-analysis was undertaken to assess whether serum AMH level may predict chances of CLB in infertile women undergoing IVF/ICSI or IUI and/or chances of live birth in women having conceived naturally. PARTICIPANTS/MATERIALS, SETTING, METHODS: A systematic review and meta-analysis was performed using the following keywords: 'AMH', 'anti-mullerian hormone', 'live-birth', 'cumulative live birth'. Searches were conducted from January 2004 to April 2021 on PubMed and Embase. Two independent reviewers carried out study selection, quality, and risk of bias assessment as well as data extraction. Odds ratios were estimated using a random-effect model. Pre-specified sensitivity analyses and subgroup analyses were performed. The primary outcome was CLB. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 32 studies were included in the meta-analysis. Overall, 27 articles were included in the meta-analysis of the relation between AMH and CLB or AMH and LB after IVF/ICSI. A non-linear positive relation was found in both cases. A polynomial fraction was the best model to describe it but no discriminant AMH threshold was shown, especially no serum AMH level threshold below which live birth could not be achieved after IVF/ICSI. After IVF-ICSI, only four studies reported CLB rate according to AMH level. No statistically significant differences in mean serum AMH levels were shown between patients with and without CLB, but with a high heterogeneity. After exclusion of two studies with high risks of bias, there was no more heterogeneity [I2 = 0%] and the mean AMH level was statistically significantly higher in women with CLB. There were not enough articles/data to assess the ability of AMH to predict CLB rate or find an AMH threshold after IUI or in women without history of infertility trying to conceive without ART. LIMITATIONS, REASONS FOR CAUTION: The systematic review and meta-analysis had some limitations owing to the limits and bias of the studies included. In the present meta-analysis, heterogeneity may have been caused by different baseline characteristics in study participants, different stimulating protocols for ART, different serum AMH level thresholds used and the use of various assays for serum AMH. This could explain, in part, the absence of a discriminating AMH threshold found in this analysis. WIDER IMPLICATIONS OF THE FINDINGS: Serum AMH level is linked to CLB rate after IVF/ICSI but no discriminating threshold can be established, therefore low serum AMH level should not be used as the sole criterion for rejecting IVF treatment, especially in young patients. Data are lacking concerning its predictive value after IUI or in women trying to conceive without ART. Our findings may be helpful to counsel candidate couples to IVF-ICSI. STUDY FUNDING/COMPETING INTERESTS: No external funding was obtained for this study. There are no conflicts of interest. REGISTRATION NUMBER: PROSPERO CRD42021269332.

BRCA 1/2 pathogenic variants increase the risk of developing early and aggressive breast cancers (BC). For these patients, fertility potential can be directly affected by oncologic treatments. In addition, evidence indicates that BRCA-mutated women had a significant reduction in their ovarian reserve. In order to improve their chances of conception after the completion of cancer treatments, fertility preservation should be proposed before the administration of gonadotoxic drugs, ideally by oocyte vitrification after controlled ovarian hyperstimulation (COH). The present investigation aims to assess the ovarian response to COH in BRCA 1/2-pathogenic-variant carriers diagnosed with BC. Patient characteristics and COH outcomes were compared between BRCA-positive (n = 54) and BRCA-negative (n = 254) patients. The number of oocytes recovered did not differ between the two groups. However, the oocyte maturation rate and the number of mature oocytes obtained (7 (4.5-11.5) vs. 9 (5-14) oocytes, p = 0.05) were significantly lower in the BRCA-mutated patients. Although individualized COH protocols should be discussed, BRCA-mutated patients would benefit from FP before BC occurs, in order to cope with the potential accelerated decline of their ovarian reserve, optimize the success rate of FP by repeating COH cycles, and to preserve the feasibility of PGT-M by collecting a large amount of eggs.
ABSTRACT
PURPOSE: The objective of the present study was to evaluate whether oocyte vitrification following controlled ovarian stimulation (COS) for fertility preservation (FP) delays the initiation of neoadjuvant chemotherapy (NAC) for breast cancer (BC) as compared to in vitro maturation (IVM). METHODS: We performed a retrospective cohort study including all BC patients eligible for oocyte vitrification following COS or in vitro maturation (IVM) before initiation of NAC between January 2016 and December 2020. The inclusion criteria were female patients aged between 18 and 40, with confirmed non metastatic BC, with indication of NAC, who have had oocyte retrieval for FP after COS, or IVM + / - cryopreservation of ovarian tissue (OTC). Various time points related to cancer diagnosis, FP, or chemotherapy were obtained from a medical record review. RESULTS: A total of 197 patients with confirmed BC who had oocyte retrieval following COS (n = 57) or IVM + / - OTC (n = 140) for FP prior to NAC were included. Overall, the average time from cancer diagnosis to chemotherapy start was similar between patients having undergone COS or IVM before oocyte vitrification (37.3 ± 13.8 vs. 36. 8 ± 13.5 days; p = 0.89). CONCLUSIONS: The indication of NAC for BC should not be considered as an impediment to urgent COS for oocyte vitrification for FP.

OBJECTIVE: To study whether fertility preservation strategies using ovarian stimulation or without using it impact long-term disease-free survival of patients with breast cancer. DESIGN: Retrospective bicentric cohort study. SETTING: Two university hospitals. PATIENT(S): In this study, 740 women with breast cancer, aged 18-43 years, who received primary fertility preservation between 2013 and 2019 after a diagnosis of localized breast cancer were included. INTERVENTION(S): Overall, 328 patients underwent at least 1 ovarian stimulation cycle (STIM group) and 412 had a technique without hormonal administration (no STIM group). MAIN OUTCOME MEASURE(S): Disease-free survival and overall survival up to May 2021 were compared between the 2 groups by log-rank test. Cox proportional-hazard regression model was used for multivariable analyses. RESULT(S): Out of the 740 women who underwent fertility preservation, follow-up data were available for 269 women in the STIM group (82%) and 330 (80%) in the no STIM group. Kaplan-Meier estimates of disease-free survival at 4 years were 87.9% (82.8%-92.2%) and 83.1% (78.4%-87.3%) in the STIM and no STIM groups, respectively. After adjustment on prognostic parameters, no significant difference in breast cancer recurrence rate was observed between the STIM and no STIM groups (hazard ratios, 0.83 [0.64-1.08]). Kaplan-Meier estimate of overall survival at 4 years was 97.6% (95.3%-99.2%) and 93.6% (90.9%-95.9%) in the STIM and no STIM groups, respectively. Overall survival was higher in the STIM group than no STIM group (log-rank test). After adjustment on prognostic parameters, the risk of death remained significantly lower in the STIM group (Hazard Ratio, 0.55 [0.35-0.85]). CONCLUSION(S): In our cohort, STIM for fertility preservation in breast cancer did not significantly impact disease-free survival but was associated with higher overall survival. The disease-free survival and overall survival of young patients with breast cancer were not impacted by fertility preservation techniques irrespective of the timing of chemotherapy (neoadjuvant or adjuvant) and the use of ovarian stimulation. Nevertheless, because death and recurrence were rare events, these results should be taken with caution.

OBJECTIVE: To determine whether pregnancies with donated embryos are at a higher risk of complications than the pregnancies from autologous frozen-thawed embryo transfer (FET). DESIGN: Anonymous, multicenter, comparative, observational, retrospective, matched-cohort study. SETTING: Six French assisted reproductive technique centers from 2003 to 2018. PATIENT(S): Seventy-three singleton pregnancies with donated embryos (exposed) and 136 singleton pregnancies after autologous FET (nonexposed) were matched at 7-8 weeks of gestation (pregnancy date, parity, and women's age) (2:1 ratio, respectively). In accordance with French practices, all women were <44 years old and donated embryos were discarded frozen embryos from other couples. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Percentages of hypertensive disorders of pregnancy (HDPs) with donated embryos versus autologous FET. RESULT(S): Groups were comparable (mean age: 34.5 years) and HDPs (24.6% vs. 11.9%) were significantly more frequent among the donated-embryo pregnancies, mostly in its severe forms (17.5% vs. 4.6%). In contrast, their respective isolated hypertension frequencies were comparable (7.0% vs. 7.3%). Multivariate analysis retained increased severe HDP risk with donated embryos (odds ratio 2.08 [95% confidence interval: 1.08-4.02]). No significant effect of endometrial preparation was observed. C-sections were more frequent for donated-embryo pregnancies (47.3% vs. 29.2%). Newborns from embryo donation or autologous FET were comparable for prematurity, birth weight and length, Apgar score, small for gestational age, large for gestational age, neonatal malformations, and sex ratio. CONCLUSION(S): Even for young women, the risk of severe HDP was 4 times higher for donated-embryo pregnancies than for autologous-FET pregnancies. The HDP risk must be acknowledged to inform donated-embryo recipients and provide careful pregnancy monitoring.

BACKGROUND: Primary Ovarian Insufficiency (POI), a public health problem, affects 1-3.7% of women under 40 yielding infertility and a shorter lifespan. Most causes are unknown. Recently, genetic causes were identified, mostly in single families. We studied an unprecedented large cohort of POI to unravel its molecular pathophysiology. METHODS: 375 patients with 70 families were studied using targeted (88 genes) or whole exome sequencing with pathogenic/likely-pathogenic variant selection. Mitomycin-induced chromosome breakages were studied in patients' lymphocytes if necessary. FINDINGS: A high-yield of 29.3% supports a clinical genetic diagnosis of POI. In addition, we found strong evidence of pathogenicity for nine genes not previously related to a Mendelian phenotype or POI: ELAVL2, NLRP11, CENPE, SPATA33, CCDC150, CCDC185, including DNA repair genes: C17orf53(HROB), HELQ, SWI5 yielding high chromosomal fragility. We confirmed the causal role of BRCA2, FANCM, BNC1, ERCC6, MSH4, BMPR1A, BMPR1B, BMPR2, ESR2, CAV1, SPIDR, RCBTB1 and ATG7 previously reported in isolated patients/families. In 8.5% of cases, POI is the only symptom of a multi-organ genetic disease. New pathways were identified: NF-kB, post-translational regulation, and mitophagy (mitochondrial autophagy), providing future therapeutic targets. Three new genes have been shown to affect the age of natural menopause supporting a genetic link. INTERPRETATION: We have developed high-performance genetic diagnostic of POI, dissecting the molecular pathogenesis of POI and enabling personalized medicine to i) prevent/cure comorbidities for tumour/cancer susceptibility genes that could affect life-expectancy (37.4% of cases), or for genetically-revealed syndromic POI (8.5% of cases), ii) predict residual ovarian reserve (60.5% of cases). Genetic diagnosis could help to identify patients who may benefit from the promising in vitro activation-IVA technique in the near future, greatly improving its success in treating infertility.

BACKGROUND: In absence of contraindication, breast cancer patients of reproductive age can undergo fertility preservation with controlled ovarian stimulation for oocyte/embryo cryopreservation before the administration of potentially gonadotoxic treatments. High hormonal levels induced by ovarian stimulation might have an adverse impact on hormone-positive breast cancer. Whether letrozole supplementation during ovarian stimulation (COSTLES) reduces serum progesterone levels after GnRHa trigger remains unknown. We aimed to determine whether COSTLES might be useful for breast cancer patients undergoing fertility preservation to reduce early luteal progesterone levels following GnRH-agonist (GnRHa)trigger. METHODS: All women who underwent COS with GnRH antagonist protocol with GnRHa trigger were included. Serum progesterone level measured 12 h after GnRHa trigger was compared between patients undergoing COS with letrozole supplementation (COSTLES group) and patients undergoing COS without letrozole (Control group) for fertility preservation purposes. RESULTS: A total of 246 patients were included, of which 84 patients (34.1%) in the COSTLES group and 162 patients (65.6%) in the Control group. All patients in the COSTLES group were BC patients (n = 84, 100%), while the Control group included 77 BC patients (47.5%). Patients in the two groups were comparable. The mean number of oocytes recovered and vitrified at metaphase 2 stage did not significantly differ between the two groups. Serum progesterone levels on the day after GnRHa trigger were significantly lower in the COSTLES group (8.6 ± 0.7 vs. 10.5 ± 0.5 ng/mL, respectively, p < 0.03), as well as serum E2 levels (650.3 ± 57.7 vs. 2451.4.0 ± 144.0 pg/mL, respectively, p < 0.01). However, the GnRHa-induced LH surge was significantly higher in in the COSTLES group (71.9 ± 4.6 vs. 51.2 ± 2.6 UI/L, respectively, p < 0.01). CONCLUSIONS: Our results show that COSTLES for fertility preservation in breast cancer patients using GnRHa trigger reduces serum progesterone levels compared to ovarian stimulation without letrozole. These findings encourage the use of COSTLES in this context to decrease the potential deleterious effect of elevated hormonal levels on hormone-positive breast cancer.

International guidelines are published to provide standardized information and fertility preservation (FP) care for adults and children. The purpose of the study was to conduct a modified Delphi process for generating FP guidelines for BGD. A steering committee identified 42 potential FP practices for BGD. Then 114 key stakeholders were asked to participate in a modified Delphi process via two online survey rounds and a final meeting. Consensus was reached for 28 items. Among them, stakeholders rated age-specific information concerning the risk of diminished ovarian reserve after surgery as important but rejected proposals setting various upper and lower age limits for FP. All women should be informed about the benefit/risk balance of oocyte vitrification-in particular about the likelihood of live birth according to age. FP should not be offered in rASRM stages I and II endometriosis without endometriomas. These guidelines could be useful for gynecologists to identify situations at risk of infertility and to better inform women with BGDs who might need personalized counseling for FP.
ABSTRACT
RESEARCH QUESTION: Do IVF treatments after conservative management of endometrial atypical hyperplasia or grade 1 endometrial adenocarcinoma (AH/EC) increase the risk of disease recurrence? DESIGN: This is a prospective cohort study from a national registry from January 2008 to July 2019. Sixty patients had an AH/EC and received progestin treatment using chlormadinone acetate for at least 3 months. After remission, 31 patients underwent IVF and 29 did not. The primary outcome was the recurrence rate at 24 months according to the use of IVF. The secondary outcome was the identification of risk factors for recurrence. RESULTS: The probability of 2-year recurrence was 37.7% (SD 10.41%) in the IVF group and 55.7% (SD 14.02%) in the no IVF group (Pâ¯=â¯0.13). Obesity, nulliparity, polycystic ovary syndrome, age and tumoural characteristics were not associated with recurrence. Pregnancy was a protective factor for recurrence, with 2-year recurrence probabilities of 20.5% and 62.0% in the pregnancy and no pregnancy groups, respectively (Pâ¯=â¯0.002, 95% CI 0.06-0.61). In contrast, the number of cycles, maximum serum oestradiol concentration during ovarian stimulation, ovarian stimulation protocol, total dose of gonadotrophin administered and thickness of the endometrium showed no significant differences in terms of the risk of recurrence in the IVF subgroup. CONCLUSION: IVF treatment after fertility-sparing management of AH/EC does not increase the risk of recurrence. Therefore, it is an acceptable strategy to decrease the time to pregnancy. Overall, the recurrence rate is high enough to justify close monitoring once remission occurs.

PURPOSE: The aim is to report the first live-birth following ICSI using spermatozoa previously vitrified in a Stripper Tip. PRINCIPAL RESULTS: A 34-year-old cryptozoospermic man was enrolled in a sperm vitrification program. After failure of conventional freezing technique, spermatozoa were vitrified using two carriers: a commercially-available, Cell Sleeper, and a "home-made" one, Stripper Tip. This man and his 30-year-old wife underwent an ICSI attempt using vitrified-warmed spermatozoa from these devices. All frozen-warmed spermatozoa were quickly recovered. Among the oocytes retrieved, six were injected with sperm from the Cell Sleeper, and seven with sperm from the Stripper tip, leading to 4 embryos in each case. Two embryos, arising from sperm frozen in the Stripper tip, were transferred, resulting in a healthy live-birth. CONCLUSIONS: This is the first successful delivery following the use of spermatozoa frozen in an original device, the Stripper Tip, giving a promising prospect for managing severe male infertilities.

PURPOSE: Is serum progesterone(P) level on day 2 of vaginal P administration in a hormonally substituted mock cycle predictive of live birth in oocyte donation(OD)? METHODS: Retrospective analysis of 110 mock cycles from 2008 to 2016 of OD recipients having at least one subsequent embryo transfer (ET). Endometrial preparation consisted of sequential administration of vaginal estradiol, followed by transdermal estradiol and 600 mg/day vaginal micronized P. In mock cycles, serum P was measured 2 days after vaginal P introduction. OD was performed 1 to 3 years later, without P measurement. RESULTS: In mock cycles, mean serum P level on day 2 was 12.8 ± 4.5 ng/mL (range: 4-28 ng/mL). A total of 32% patients had P < 10 ng/mL. At the time of first OD, age of recipients and donors, number of retrieved and attributed oocytes, and number of transferred embryos were comparable between patients with P < 10 ng/mL in their mock cycles compared with P ≥ 10 ng/mL. Pregnancy and live birth rate after first ET were significantly lower for patients with P < 10ng/mL (9% vs. 35 %; P = 0.002 and 9% vs. 32%; P = 0.008, respectively). Considering both fresh and subsequent frozen-thawed ET, cumulative live birth rate per-patient and per-transfer were significantly lower in patients with P < 10 ng/mL in their mock cycle (14% vs. 35%; P = 0.02 and 11% vs. 27%; P = 0.03). CONCLUSION: A low P level in hormonally substituted cycles several years before ET performed with the same endometrial preparation is associated with a significantly lower chance of live birth. This suggests that altered vaginal P absorption is a permanent phenomenon. Monitoring serum P in hormonally substituted cycles appears mandatory to adjust luteal P substitution.

RESEARCH QUESTION: Does the relative distribution of anti-Müllerian hormone (AMH) isoforms differ between patients depending on their body mass index (BMI) and polycystic ovary syndrome (PCOS) status in serum and follicular fluid? DESIGN: Obese and normal weight patients (PCOS [nâ¯=â¯70]; non-PCOS [nâ¯=â¯37]) were selected for this case-control study in the serum. Between 2018 and 2019, obese (nâ¯=â¯19) and normal weight (nâ¯=â¯20) women with or without PCOS who were receiving IVF treatment were included in the follicular fluid study. The bio-banked serums and follicular fluid were tested for total AMH (proAMH and AMHN,C combined) and proAMH using an automatic analyzer. The AMH prohormone index (APIâ¯=â¯[proAMH]/[total AMH]x 100) was calculated as an inverse marker of conversion of proAMH to AMHN,C, with only the latter isoform that could bind to the AMH receptor complex. RESULTS: The API was not significantly different between controls and women with PCOS, whereas obese women had a lower API compared with their normal weight counterparts. Grouping PCOS and controls, a lower API was found in obese versus normal weight women, suggesting a greater conversion of proAMH to AMHN,C. The API in the serum was significantly correlated with metabolic parameters. In the follicular fluid, API is not different between obese and normal weight women independently of PCOS and is higher than in the concomitant serum. CONCLUSIONS: The proportion of inactive form of AMH in the serum is higher in normal weight versus obese women but not in the follicular fluid, independently of PCOS. The conversion of proAMH into the cleaved isoform is likely to occur in extra-ovarian tissues and to exacerbate in obese individuals.

OBJECTIVE: To describe knowledge and attitudes toward fertility preservation (FP) in patients with endometrial atypical hyperplasia or adenocarcinoma (EC/AH) among French gynecologists MATERIALS AND METHODS: A national survey among French gynaecologists: one questionnaire with one common part and two specific parts for gynecological surgeon (GS) or for specialists in reproductive medicine (SRM) was sent from April 2017 to April 2018. Knowledge and attitudes toward FP in EC/AH were evaluated with a "knowledge score" and an "attitudes score" using a four- or five-point Likert scale. RESULTS: One hundred forty physicians completed the survey (87 GS, 53 SRM). The knowledge score was low (59.3% medium/low), but it was significantly higher for GS compared to SRM. The better-known treatments were oral progestins and hysteroscopic resection. Among the participants treating EC/AH, 52.6% found it "difficult" to manage patients and 61.8% regretted the lack of official recommendations. Most physicians seemed to be uncomfortable/unsupportive with FP in EC/AH (57.2% "attitude score' below 11/20). There was a positive correlation between knowledge and attitude scores. GS "usually/always" give advice to patients about FP before EC/AH treatment. After maximum 3-6 months, 56.6% of SRM chose In Vitro Fecundation (IVF) to reduce time-to-pregnancy, with GnRH antagonist protocols (28%) or mild-stimulation (15.1%) to avoid hyperoestrogenism. CONCLUSIONS: Despite reassuring results in the literature, French gynecologists are uncomfortable with FP using EC/AH conservative management, which may be because of a lack of confidence in their knowledge. Specific guidelines are needed to help physicians manage these young patients and their fertility.

OBJECTIVE: To study which endometrial preparation allows a better ongoing pregnancy rates (OPR) and live birth rate (LBR) after frozen-thawed embryo transfer (FET) between mild gonadotropin ovarian stimulation (OS) and artificial cycles (AC). STUDY DESIGN: Retrospective follow-up study including all FET performed in one fertility center from 2013 to 2016. In the OS group, gonadotropins were followed by r-hCG triggering. Vaginal micronized progesterone (200â¯mg/day) was given systematically. In the AC group, estradiol (E2) was started on Day 1. Vaginal micronized progesterone (600â¯mg/d) was added to E2 for 12 weeks. Data were analyzed using a multiple regression model. RESULTS: Among 1021 FETs, 35% underwent OS preparation, 65% had an AC. As expected, patients in the AC group suffered more from endometriosis (18.5% vs. 12.9%; pâ¯=â¯.021) and polycystic ovarian syndrome (21.7% vs. 10.9%; pâ¯<â¯.0001) than patients in the OS group. There was no difference between groups with respect to endometrial thickness, number of embryos transferred, development stage at FET, cryopreservation technique. Despite a similar clinical pregnancy rate (CPR) (24.4% vs. 20.8%; pâ¯=â¯.189), the OPR was significantly higher in the OS than in the AC group (17.9% vs. 11%; pâ¯=â¯.002), leading to an increased LBR (17.1% vs. 9.8%; pâ¯<â¯.001). After adjusting for parameters usually linked to early pregnancy losses or potential bias (patient age at freezing, smoking status, PCOS, endometriosis, rank of transfer and previous miscarriages), the results remained significant. CONCLUSION: Despite a similar CPR, LBR was significantly higher with mild OS than with the AC preparation, even after adjusting for potential confounders. In light of these results, the first-line endometrial preparation could be OS instead of an AC. In an AC, a potential defect of the luteal phase may exist, treatment could be optimized to avoid pregnancy losses. A randomized controlled trial should be undertaken to assess the role of OS and ACs in FET.

Since its initial discovery in the 1940s, research into the physiological actions of anti-Müllerian hormone (AMH), from its eponymous role in male developmental biology to its routine clinical use in female reproductive health, has undergone a paradigm shifting change. With several exciting studies recently reporting hitherto unforeseen AMH actions at all levels in the hypogonadal-pituitary-gonadal axis, the importance of this hormone for both hypothalamic and pituitary reproductive control is finding increasing support and significance. In this review, we will briefly summarize what is known about the traditional roles and biology of AMH and how this could be integrated with new findings of AMH actions at the level of the hypothalamic-pituitary axis. We also synthesize the important findings from these new studies and discuss their potential impact and significance to our understanding of one of the most common reproductive disorders currently affecting women, polycystic ovary syndrome.
