Can a machine learning model better predict the cumulative live birth rate for a couple after intrauterine insemination or embryo transfer than Cox regression based on their personal characteristics?Retrospective cohort study conducted in two French infertility centres (Créteil and Tenon Hospitals) between 2012 and 2019, including 1819 and 1226 couples at Créteil and Tenon, respectively. Two models were applied: a Cox regression, which is almost exclusively used in assisted reproductive technology (ART) predictive modelling, and a tree ensemble-based model using XGBoost implementation. Internal validations were performed on each hospital dataset separately; an external validation was then carried out on the Tenon Hospital's population.The two populations were significantly different, with Tenon having more severe cases than Créteil, although internal validations show comparable results (C-index of 60% for both populations). As for the external validation, the XGBoost model stands out as being more stable than Cox regression, with the latter having a higher performance loss (C-index of 60% and 58%, respectively). The explicability method indicates that the XGBoost model relies strongly on features such as the ages of a couple, causes of infertility, and the woman's body mass index or infertility duration, which is consistent with the ART literature about risk factors.Overall performances are still relatively modest, which is coherent with all reported ART predictive models. Explicability-based methods would allow access to new knowledge, to gain a greater comprehension of which characteristics and interactions really influence a couple's journey. These models can be used by practitioners and patients to make better informed decisions about performing ART.

Introduction : Up to 30% of couples may face secondary infertility. The impact of ectopic pregnancy, spontaneous abortion, pregnancy termination or live birth with caesarean section may impair further fertility in different ways. However, secondary infertility after physiological vaginal life childbirth has been little studied. The aim of this study was to describe the population and the fertility issues and analyze the predictive factors of success in in vitro fertilization in women presenting secondary infertility after a physiological vaginal childbirth. Material and methods : This single-centre retrospective study included women aged 18-43 years consulting between 2013 and 2020 for secondary infertility in a couple having already had previous vaginal life childbirth. Couples’ characteristics, management decision after the first consultation and IVF outcomes were analyzed. Results : Secondary infertility was found in 286 couples, out of whom 138 had a history of vaginal life childbirth. Population was characterized by an advanced female age and overweight. After the first consultation, IVF was performed in only 40% of couples. No predictive factor of live birth was found. Conclusion : Our study shows that in couples with secondary infertility after prior physiological delivery cigarette smoking is frequent in male partners, and ovarian reserve markers are altered. However, no statistically significant predictive factor of live birth after IVF treatment has been identified. Further large prospective studies are necessary.

International audience; 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 personalizedcounseling for FP.

International guidelines are published in oncology to provide standardized information and fertility preservation (FP) care for adults and children with cancer. For benign gynecologic diseases (BGD), many recommendations are based on data coming from oncofertility studies rather than studies with a stronger and broader evidence base. 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.

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.

Research question Does mild COVID-19 infection affect the ovarian reserve of women undergoing an assisted reproductive technology (ART) protocol? Design A prospective observational study was conducted between June and December 2020 at the ART unit of Tenon Hospital, Paris. Women managed at the unit for fertility issues by in-vitro fecundation, intracytoplasmic sperm injection (IVF/ICSI), fertility preservation, frozen embryo transfer or artificial insemination, and with an anti-Mullerian hormone (AMH) test carried out within 12 months preceding ART treatment, were included. All the women underwent a COVID rapid detection test (RDT) and AMH concentrations between those who tested positive (RDT positive) and those who tested negative (RDT negative). Results The study population consisted of 118 women, 11.9% (14/118) of whom were COVID RDT positive. None of the tested women presented with a history of severe COVID-19 infection. The difference between the initial AMH concentration and AMH concentration tested during ART treatment was not significantly different between the COVID RDT positive group and COVID RDT negative group (–1.33 ng/ml [–0.35 to –1.61) versus –0.59 ng/ml [–0.15 to –1.11], P = 0.22). Conclusion A history of mild COVID-19 infection does not seem to alter the ovarian reserve as evaluated by AMH concentrations. Although these results are reassuring, further studies are necessary to assess the effect of COVID-19 on pregnancy outcomes in women undergoing ART.

Introduction Recurrent miscarriages are defined as three or more early miscarriages before 12 weeks of gestation. The aim of this study was to describe a cohort of women with unexplained recurrent miscarriages, evaluate several potential biomarkers of immune origin and describe the outcome of pregnancies under immunomodulatory therapies METHODS: Women having a history of at least 3 early miscarriages without any etiology were recruited from 3 university hospitals. Results Among 101 women with recurrent miscarriages, overall, 652 pregnancies have been included in the analysis. Women which experienced miscarriages were older (33.3 ± 5.4 versus 31.9 ± 6.7; p = 0.03), with history of more pregnancies (4 (2-6) versus 3.5 (1-5.75); p 0.0008), and less frequently the same partner (406 (74%) versus 79 (86%); p=0.01). There was no difference in the level and frequencies of biomarkers of immune origin (NK, lymphocyte, gammaglobulins and blood cytokine levels and endometrial uNK activation status), except the higher rates of positive antinuclear antibodies in women with live birth (12 (13%) versus 36 (7%); p=0.03). Among the 652 pregnancies, 215 (33%) have been treated and received either aspirin/low weighted molecular heparin (LMWH) and/or combined to different lines of immunomodulatory treatment. Patients with pregnancy under treatment had a significantly higher rate of cumulative live birth rate that those with untreated ones (43.0% vs 34.8%; p = 0.04). When compared to patients with untreated pregnancies, patients with steroids during the pregnancy had twice more chances to obtain live birth (OR 2.0, CI95% 1.1 - 3.7, p = 0.02). Conclusions Unexplained recurrent miscarriages could have improved obstetrical outcome under immunomodulatory therapies and in particular steroids.

Results from studies reporting the optimal stimulation duration of IVF-ICSI cycles are inconsistent. The aim of this study was to determine whether, in the presence of early ovulation-triggering criteria, prolonged ovarian stimulation modified the chances of a live birth. This cross-sectional study included 312 women presenting triggering criteria beginning from D8 of ovarian stimulation. Among the 312 women included in the study, 135 were triggered for ovulation before D9 (D ≤ nine group) and 177 after D9 (D > nine group). The issues of fresh +/− frozen embryo transfers were taken into consideration. Cumulative clinical pregnancy and live-birth rates after fresh +/− frozen embryo transfers were similar in both groups (37% versus 46.9%, p = 0.10 and 19.3% versus 28.2%, p = 0.09, respectively). No patient characteristics were found to be predictive of a live birth depending on the day of ovulation trigger. Postponing of ovulation trigger did not impact pregnancy or live-birth rates in early responders. A patient’s clinical characteristics should not influence the decision process of ovulation trigger day in early responders. Further prospective studies should be conducted to support these findings.

Background The management of endometriosis-related infertility is still under debate. The Endometriosis Fertility Index (EFI) score is performant to predict the occurrence of a spontaneous pregnancy following surgery, but was not evaluated in a cost-effectiveness perspective. Our objective was to quantify fertility outcomes, and costs of different care pathways for endometriosis-associated infertility after primary surgery, with a stratification on the EFI score. Study design We conducted a cost-effectiveness analysis based on a decision-tree model in a Tertiary-care university hospital. Extracted form a prospectively maintained database, 608 patients with endometriosis-associated infertility, who underwent laparoscopic treatment with an evaluation of the EFI score, were discriminated between different strategies: natural conception, immediate IVF-ICSI, delayed IVF-ICSI. The pregnancy rate and the live birth rate were the effectiveness outcomes. We considered direct and indirect costs in each strategies. The analysis was stratified according to the EFI score. Results After surgery, 163 women with immediate IVF-ICSI (strategy I) were compared with 445 women who had natural conception attempts during a year (strategy II). After a year failure of natural conception attempts, 133 women continuing natural conception attempts (strategy III) were compared with 168 women who had delayed IVF-ICSI (strategy IV). The respective PR and LBR were 62.6 % and 52.1 % for strategy I, and 32.4 % and 23.8 % for strategy II. Compared to strategy II, strategy I was more costly and more effective (Incremental Cost Effectiveness Ratio (ICER): 31,469 €/pregnancy and 33,568 €/live birth)). No added benefit was observed for patients in strategy I with an EFI score [0−3] after two IVF-ICSI cycles. Strategy III was strongly dominant versus strategy IV for patients with an EFI score [9–10]. Compared to strategy III, strategy VI was more costly and more effective (ICER: 79,674 €/pregnancy, 53,188 €/pregnancy and 27,748 €/pregnancy respectively for patients with an EFI score [7–8], [4–6] and [0−3]). Conclusion Immediate IVF-ICSI after surgery is effective but associated with substantial costs for the healthcare system. Taking into account healthcare costs, the EFI is a useful score for helping a couple decide between different care pathways –natural conception, immediate or delayed IVF-ICSI– after surgery for endometriosis-associated infertility.

Recurrent implantation failure is defined as the absence of pregnancy after at least three transfers of good-quality embryos after in vitro fecundation/intracytoplasic sperm injection.The aim of this study was to describe a multicentre cohort of women with unexplained RIF, to analyse the factors associated with clinical pregnancy and to evaluate the immunomodulatory therapies efficacy.Women were consecutively recruited from university departments with unexplained RIF.Sixty-four women were enrolled with mean age 36 ± 3 years. The rates of clinical pregnancy in 64 women were compared in untreated and treated cycles and according to therapies used during the last prospectively followed embryo transfer. A clinical pregnancy after the transfer was noted in 56 % pregnancies on intralipids and in 50 % on prednisone, versus 5 % in untreated ones (p0.001). The 340 embryo transfers of these 64 women resulted in 68 clinical pregnancies and 18 live births. Clinical pregnancies were significantly more frequent in treated versus untreated embryo transfers (44 % vs 9 %; p0.001) with odds ratio at 8.13 (95 % CI 4.49-14.72, p0.0001). Cumulative pregnancy rates were higher for steroid-treated transfers than for untreated transfers when considering overall transfers before and after using steroids and also only those under steroids. Cumulative pregnancy rates were not different from steroid- and intralipid-treated embryo transfers CONCLUSIONS: In this multicentre study of women with unexplained RIF, use of immunomodulatory treatments before embryo transfer resulted in higher clinical pregnancy. Randomised, well-designed studies in well-defined population of RIF women are necessary to confirm our preliminary data.

International audience; Background: Endometriosis is a multifactorial pathology dependent on intrinsic and extrinsic factors, but the immune deregulation seems to play a pivotal role. In endometriosis-associated infertility this could raise the benefit of immunomodulatory strategies to improve the results of ART. In this review, we will describe (1) sera and peritoneal fluid cytokines and immune markers; (2) autoantibodies; (3) immunomodulatory treatments in endometriosis with infertility.Methods: The literature research was conducted in Medline, Embase and Cochrane Library with keywords: "endometriosis", "unexplained miscarriage", "implantation failure", "recurrent implantation failure » and « IVF-ICSI », « biomarkers of autoimmunity", "TNF-α", "TNF-α antagonists", "infliximab", "adalimumab", "etanercept", "immunomodulatory treatment", "steroids", "intralipids", "intravenous immunoglobulins", "G-CSF", "pentoxyfylline".Results: Several studies analyzed the levels of pro-inflammatory cytokines in sera and peritoneal fluid of endometriosis-associated infertility, in particular TNF-α. Various autoantibodies have been found in peritoneal fluid and sera of infertile endometriosis women even in the absence of clinically defined autoimmune disease, as antinuclear, anti-SSA and antiphospholipid autoantibodies. In few uncontrolled studies, steroids and TNF-α antagonists could increase the pregnancy rates in endometriosis-associated infertility, but well-designed trials are lacking.Conclusion: Endometriosis is characterized by increased levels of cytokines and autoantibodies. This suggests the role of inflammation and immune cell deregulation in infertility associated to endometriosis. The strategies of immunomodulation to regulate these immune deregulations are poorly studied and well-designed studies are necessary.

Purpose A protective effect of anti-Müllerian hormone (AMH) on follicle atresia was recently demonstrated using long-term treatments, but this effect has never been supported by mechanistic studies. This work aimed to gain an insight into the mechanism of action of AMH on follicle atresia and on how this could account for the increased follicle pool observed in women with polycystic ovary syndrome (PCOS). Methods In vivo and in vitro experiments were performed to study the effects of AMH on follicle atresia and on the proliferation and apoptosis of granulosa cells (GCs). RNA-sequencing was carried out to identify new AMH target genes in GCs. The expression of some of these genes in GCs from control and PCOS women was compared using microfluidic real time quantitative RT-PCR. Results A short-term AMH treatment prevented follicle atresia in prepubertal mice. Consistent with this result, AMH inhibited apoptosis and promoted proliferation of different models of GCs. Moreover, integrative biology analyses of 965 AMH target genes identified in 1 of these GC models, confirmed that AMH had initiated a gene expression program favoring cell survival and proliferation. Finally, on 43 genes selected among the most up- and down-regulated AMH targets, 8 were up-regulated in GCs isolated from PCOS women, of which 5 are involved in cell survival. Main conclusions Our results provide for the first time cellular and molecular evidence that AMH protects follicles from atresia by controlling GC survival and suggest that AMH could participate in the increased follicle pool of PCOS patients.

Background PPOS protocols, initially described for FP in women with cancer, have many advantages compared to antagonist protocols. PPOS protocols were not evaluated for women with endometriosis. The objective of the study was to describe fertility preservation outcomes in women with endometriosis and to compare an antagonist protocol with a Progestin-Primed Ovarian Stimulation (PPOS) protocol. Method We conducted a prospective cohort study associated with a cost-effectiveness analysis in a tertiary-care university hospital. The measured outcomes included the numbers of retrieved and vitrified oocytes, and direct medical costs. In the whole population, unique and multiple linear regressions analysis were performed to search for a correlation between individual characteristics and the number of retrieved oocyte. Results We included 108 women with endometriosis who had a single stimulation cycle performed with either an antagonist or a PPOS protocol. Overall, 8.1 ± 6.6 oocytes were retrieved and 6.4 ± 5.6 oocytes vitrified per patient. In the multiple regression model, age (p = 0.001), prior ovarian surgery (p = 0.035), and anti-Mullerian hormone level (p = 0.001) were associated with the number of retrieved oocytes. Fifty-four women were stimulated with an antagonist protocol, and 54 with a PPOS protocol. A mean of 7.9 ± 7.4 oocytes were retrieved in the antagonist group and 8.2 ± 5.6 in the PPOS group (p = 0.78). A mean of 6.4 ± 6.4 oocytes were vitrified in the antagonist group and 6.4 ± 4.7 in the PPOS group (p = 1). In the cost-effectiveness analysis, the PPOS protocol was strongly dominant over the antagonist protocol. Conclusion Fertility preservation procedures are feasible and effective for patients affected by endometriosis. Antagonist and PPOS protocols were associated with similar results but the medico-economic analysis was in favor of PPOS protocols.

Objective Adipokines could be a link between metabolic syndrome (MS) and infertility. While the association between circulating adipokines and fertility has been extensively studied in females, this relationship in males was less investigated, although some adipokines are detectable in seminal plasma (SP). The aim of this study was to determine adipokine levels in blood and SP and to assess the relationships between adipokines, MS and semen parameters in men from infertile couples. Design Male partners of infertile couples referred to four medical French centers were enrolled in years 2013–2016. Methods Subjects (n = 160) aged 18–45 years were assessed for anthropometric, biochemical, sperm, and circulating hormonal parameters. Leptin, adiponectin, resistin, chemerin, visfatin, and IL-6 were measured in serum and SP. Results Infertility duration was higher in men with than without MS. Adipokine concentrations were higher in blood than in SP, except for IL-6 and visfatin. The most striking result was the significant correlation observed between seminal IL-6 and spermatozoid concentration, progressive motility, and sperm vitality. Moreover, while men with MS exhibited an expected lower adiponectinemia, they displayed 2.1-fold higher adiponectin levels in SP than men without MS. Finally, logistic regression analysis showed that BMI, infertility duration, and adiponectin serum/SP ratio were independently associated with MS. Conclusions These results suggest an involvement of seminal adipokines to modulate fertility in men with MS and that seminal IL-6 could play a beneficial role on sperm functionality. Further mechanistic studies are necessary to investigate the precise roles of these adipokines in male reproduction.

This study aimed to assess the application of the French guidelines for pregnancies in Turner syndrome (TS) and their impact on perinatal prognosis.We performed a French multi-center retrospective study (14 centers), including TS pregnant patients (spontaneously or by Assisted Reproductive Technology (ART)) between January 2006 and July 2017. Only clinical pregnancies were analyzed. The adjustment of medical follow-up modalities to French guidelines was evaluated for all pregnancies after 2009. Pregnancies from oocyte donation (OD) after 2009 were compared to those of a cohort of TS pregnancies obtained by OD before 2009, which were reported by the French Study Group for Oocyte Donation.One hundred seventy pregnancies in 103 patients were included: 35 spontaneous, 5 by means of intra-conjugal ART, and 130 with OD. No serious maternal complications were observed. We reported two stillbirths and one intra uterine fetal death. The French guidelines were partially respected. The preconceptional assessment was carried out in 74% of cases. Cardiology follow-up during pregnancy was performed in accordance with guidelines in 74% of patients. Postpartum cardiac ultrasonography was performed in 45% of pregnancies but only in 11% within 8 days post-partum. When compared to the 2009 historical cohort, the rates of high blood pressure (19% vs. 38%; p 0.005) pre-eclampsia (8% vs. 21%; p 0.005) and prematurity35 weeks (15% vs 38%; p 0.0001) were lower.The implementation of guidelines has allowed the standardization of TS pregnancy care and improved perinatal indicators for both mothers and children. However, an effort must be done, in a postpartum survey.

Points essentiels L’endometriose est une pathologie frequente, source de douleurs et d’infertilite. Chez une femme infertile avec endometriose peritoneale superficielle et permeabilite tubaire conservee, une cœlioscopie operatoire est recommandee, suivie d’une stimulation ovarienne seule ou associee a des inseminations intra-uterines. En cas d’endometriose ovarienne ou profonde, les places respectives de la chirurgie et de l’assistance medicale a la procreation restent a definir precisement. La fecondation in vitro est generalement proposee apres echec d’un maximum de trois inseminations, d’emblee en cas d’endometriose ovarienne ou profonde, ou s’il existe un facteur associe d’infertilite, en particulier masculin. Avant l’hyperstimulation ovarienne en vue de fecondation in vitro, un pretraitement de 2 a 6 mois par agoniste de la GnRH ou de 6 a 8 semaines par estroprogestatifs ameliorerait les chances de grossesse. Le don d’ovocytes est efficace en cas d’insuffisance ovarienne avancee ou d’absence de reponse a la stimulation ovarienne. La preservation de la fertilite, surtout par vitrification d’ovocytes, peut etre proposee preventivement aux femmes presentant un risque d’insuffisance ovarienne, sans desir proche de grossesse.

Background or objective Endometriosis is common in women referred for infertility. In vitro fertilization provides good results but the choice of the best-controlled ovarian hyperstimulation protocol remains a subject of debate. The objective of this retrospective study was to compare pregnancy outcomes in women with endometriosis-associated infertility after COH with a long agonist protocol or a six-week oral contraception-antagonist protocol. Material and methods Retrospective analysis of a prospective database identified 284 COH cycles – 165 with GnRH-agonist protocol (GnRH-agonist group) and 119 with GnRH-antagonist protocol (GnRH-antagonist group) – in 218 women, with endometriosis from January 2013 to October 2015. Results No difference in the epidemiological characteristics was found between the groups. Per started cycle, pregnancy and live-birth rates after fresh embryo transfer were higher with the GnRH-agonist protocol (25% vs. 13%, P = 0.02 and 18% vs. 8%, P = 0.04, respectively). Considering analysis per cycle with embryo transfer, the pregnancy rate was similar in both groups while the live-birth rate was higher in the GnRH-agonist group (29% vs. 17%, P = 0.053 and 22% vs. 10%, P = 0.02, respectively). No difference was observed between the groups with freeze-thaw embryo transfer. Subgroup analysis (endometrioma alone, deep infiltrating endometriosis with and without endometrioma, endometriosis with and without adenomyosis) revealed no difference between the groups for either pregnancy or live-birth rates. Conclusion A GnRH-agonist protocol appears to result in higher pregnancy and live-birth rates after fresh embryo transfer in women with endometriosis-associated infertility, suggesting that a GnRH-antagonist protocol might negatively impact endometrial receptivity.

Objective Endometriosis affects 10% of women in reproductive age and alters fertility. Its management is still debated notably the timing of surgery and ART in infertility. Several tools have been created to guide the practitioner and the couple yet many limitations persist. The objective is to create a nomogram to predict the likelihood of a live birth after surgery followed by assisted reproductive technology (ART) for patients with endometriosis-related infertility. Study design All women in a public university hospital who attempted to conceive by ART after surgery for endometriosis-related infertility from 2004 to 2016 were included. We created a model using multivariable linear regression based on a retrospective database. Result Of the 297 women included, 171 (57.6%) obtained a live birth. Age, duration of infertility, number of ICSI-IVF cycles, ovarian reserve and the revised American Fertility Society (rAFS) score were included in the nomogram. The predictive model had an area under the curve (AUC) of 0.77 (95% CI, 0.75–0.79) and was well calibrated. The external validation of the model was achieved with an AUC of 0.71 (95% CI, 0.69–0.73) and calibration was good. The staging accuracy according to AUC criteria for the nomogram compared to the currently used Endometriosis Infertility Index to predict live births were 0.77 (95% CI, 0.75–0.79) and 0.60 (95% CI: 0.57–0.63), respectively. Conclusion This simple tool appears to accurately predict the likelihood of a live birth for a patient undergoing ART after surgery for endometriosis-related infertility. It could be used to counsel patients in their choice between spontaneous versus ART conception, or oocyte donation.

OBJECTIVE To study the fertility and live birth (LB) rate in women after surgery for deep infiltrating endometriosis (DIE) without bowel involvement and to evaluate the predictive factors of LB after DIE surgery without bowel involvement. STUDY DESIGN Retrospective cohort study. A total of 118 women who wished to conceive and who underwent surgery for DIE without bowel involvement were analyzed between January 2006 and December 2014. A multivariate logistic regression analysis of selected factors and a nomogram to predict the subsequent LB rate was constructed. RESULTS Thirty-six woman had a LB (30.5%). In multivariate analysis, factors associated with a LB were: age ≤30 years (p = 0.0024), BMI ≤ 25 kg/m2 (p = 0.029) and Enzian grade 1 (p

The incidence (rate per 100 000) of borderline ovarian tumors (BOTs) increases progressively with age, starting at 15-19 years and peaking at around 4.5 cases per 100 000 at an age of 55-59 years (LE3) with a median age of 46 years. The five year survival for FIGO stages I, II, III and IV is 99.7 % (95 % CI: 96.2-100 %), 99.6 % (95 % CI: 92.6-100 %), 95.3 % (95 % CI: 91.8-97.4 %) and 77.1 % (95 % CI: 58.0-88.3 %), respectively (LE3). An epidemiological association exists between the individual risk of BOT and family history of BOT and certain other cancers (pancreatic, lung, bone, leukemia) (LE3), a personal history of benign ovarian cyst (LE2), a personal history of tubo-ovarian infection (LE3), the use of a levonorgestrel intrauterine device (LE3), oral contraceptive use (LE3), multiparity (LE3), Hormonal replacement therapy (LE3), high consumption of Coumestrol (LE4), medical treatment for infertility with progesterone (LE3) and non-steroidal anti-inflammatory drug use (LE3). Screening for BOTs is not recommended for patients (Grade C). The overall risk of recurrence of BOTs varies between 2% and 24 %, with an overall survival greater than 94 % at 10 years, and the risk of an invasive recurrence of a BOT ranges from 0.5 % to 3.8 %. The use of scores and nomograms can be useful in assessing the risk of recurrence, and providing patients with information (Grade C). The WHO classification is recommended for classifying BOTs. It is recommended that the presence of a microinvasive focus (5 mm) and microinvasive carcinoma (5 mm with an atypical nuclei and a desmoplastic stroma reaction) within a BOT be reported. In cases of serous BOT, it is recommended to specify the classic histological subtype or micropapillary / cribriform type (Grade C). When confronted with a BOT, it is recommended that the invasive or non-invasive nature of peritoneal implants can be investigated based solely on the invasion and destruction of underlying adipose or peritoneal tissue which has a desmoplastic stromal reaction where in contact with the invasive clusters (Grade B). For bilateral mucinous BOTs and / or in cases with peritoneal implants or peritoneal pseudomyxoma, it is recommended to also look for a primitive digestive or pancreato-biliary cancer (Grade C). It is recommended to sample ovarian tumors suspected of being BOTs by focusing samples on vegetations and solid components, with at least 1 sample per cm in tumors with a size less than 10 cm and 2 samples per cm in tumors with a size greater than 10 cm (Grade C). In cases of BOTs and in the absence of macroscopic omental involvement after careful macroscopic examination, it is recommended to perform at least 4-6 systematic sampling blocks and to include all peritoneal implants (Grade C). It is recommended to consult an expert pathologist in gynecology when a BOT suspicion requires intraoperative extemporaneous histology (grade C). Endo-vaginal and suprapubic ultrasonography are recommended for the analysis of an ovarian mass (Grade A). In case of an undetermined ovarian lesion on ultrasonography, it is recommended that a pelvic MRI be performed (Grade A). To analyze an adnexal mass with MRI, it is recommended to use an MRI protocol with T2, T1, T1 Fat Sat, dynamic and diffusion sequences as well as gadolinium injection (Grade B). To characterize an adnexal mass with MRI, it is recommended to include a score system for malignancy (ADNEX MR/O-RADS) (Grade C) in the report and to formulate a histological hypothesis (Grade C). Pelvic MRI is recommended to characterize a tumor suspected of being a BOT (Grade C). Macroscopic MRI features should be analyzed to differentiate BOT subtypes (Grade C). Pelvic ultrasound is the first-line examination for the detection and characterization of adnexal masses during pregnancy (Grade C). Pelvic MRI is recommended from 12 weeks of gestation in case of an indeterminate adnexal mass and should provide a diagnostic score (Grade C). Gadolinium injection must be minimized as fetal impairment has been proven (Grade C). It is recommended that serum levels of HE4 and CA125 be evaluated and that the ROMA score for the diagnosis of an indeterminate ovarian mass on imaging be used (grade A). In case of suspicion of a mucinous BOT on imaging, dosage of serum levels of CA 19-9 can be considered (Grade C). If the determination of tumor markers is normal preoperatively, routine dosage of tumor markers in BOT follow-up is not recommended (Grade C). In case of preoperative elevation in tumor markers, the determination of serum CA 125 levels is recommended in the follow-up of BOT (Grade B). When conservative treatment of a BOT has been adopted, the use of endovaginal and transabdominal ultrasonography is recommended during follow-up (Grade B).

We aimed to compare the proportion of peripheral blood natural killer (NK) cells (CD3–CD56+) and T-cell large granular lymphocytes (CD8+CD57+) during preconception in a homogenous group of women with unexplained well-defined recurrent miscarriage (RM) and repeated implantation failure (RIF) vs healthy controls in relation to pregnancy outcomes. This case–control study followed by a literature review and meta-analysis was conducted in three university hospitals. Patients and controls were consecutively recruited from December 2015 to October 2017. In total, 115 women were included in the study: 54 with RM, 41 with RIF and 20 healthy controls with ≥ 2 term births. Percentages of CD3–CD56+ and CD8+CD57+ cells and sub-populations of CD3–CD56+ cells did not differ between cases and controls. The results for women with subsequent miscarriage did not differ from those with live births. The meta-analysis of the literature showed higher NK-cell proportions in RM [mean difference 3.47 (95% CI 2.94–4.00); p

The management of endometriosis related infertility requires a global approach. In this context, the prescription of an anti-gonadotropic hormonal treatment does not increase the rate of non-ART (assisted reproductive technologies) pregnancies and it is not recommended. In case of endometriosis related infertility, the results of IVF management in terms of pregnancy and birth rates are not negatively affected by the existence of endometriosis. Controlled ovarian stimulation during IVF does not increase the risk of endometriosis associated symptoms worsening, nor accelerate the intrinsic progression of endometriosis and does not increase the rate of recurrence. However, in the context of IVF management for women with endometriosis, pre-treatment with GnRH agonist or with oestrogen/progestin contraception improve IVF outcomes. There is currently no evidence of a positive or negative effect of endometriosis surgery on IVF outcomes. Information on the possibilities of preserving fertility should be considered, especially before surgery.

Endometriosis is a common condition, causing pain and infertility. In infertile woman with superficial peritoneal endometriosis and patent tubes, laparoscopy is recommended, followed by ovarian stimulation alone or in combination with intrauterine inseminations. In case of ovarian or deep endometriosis, the indications of surgery and assisted reproductive technologies remain to be defined precisely. In vitro fertilization is generally proposed after the failure of up to three inseminations, directly for ovarian or deep endometriosis, or in case of an associated factor of infertility, mainly male. Before ovarian stimulation in view to in vitro fertilization, a pretreatment by GnRH agonist for 2 to 6 months or combined contraceptive for 6 to 8 weeks would improve the pregnancy rate. Egg donation is effective in patients with advanced ovarian failure or lack of ovarian response to stimulation. Fertility preservation, especially by oocytes vitrified, must be proposed preventively to women with endometriosis at risk of ovarian failure, without close wish to be pregnant.

Deep infiltrating endometriosis is the most severe form of the disease, defined by infiltration beneath the peritoneum greater than 5mm. It affects several anatomical locations including the bladder, the vesico-uterine cul-de-sac, the torus uterinum, the uterosacral ligament, rectovaginal septum and the colon-rectum. Deep infiltrating endometriosis is associated with infertility. Surgery performed for deep infiltrating endometriosis in the context of pain offers good pregnancy rates either spontaneously or after assisted reproductive technologies. The results are less favorable when digestive tract is involved. IVF performed in the context of deep infiltrating endometriosis allows very satisfactory results and does not entail risks of aggravation of the pathology. There is currently no clear evidence to support either IVF or surgery to manage infertility associated with deep infiltrating endometriosis, but patients should be informed, although a risk of severe complication exists, that surgery is the only way to increase the chances of spontaneous fertility.

Background: To evaluate the impact of the association of endometrioma with or withoutdeep infiltrating endometriosis (DIE) after a first intra cytoplasmic sperm injection- invitro fertilization (ICSI-IVF) cycle on pregnancy rate.Materials and Methods: In this retrospective study, women with endometrioma whounderwent a first ICSI-IVF cycle from January 2007 to June 2010 were reviewed forpregnancy rate. The main outcome measure was the clinical pregnancy rate. A multiplelogistic regression (MLR) was performed; including all variables that were correlatedto the conception rate. Only independent factors of pregnancy rate were included in aRecursive Partitioning (RP) model.Results: The study population consisted of 104 patients (37 without DIE and 67 patientswith associated DIE). Using multivariable analysis, a lower pregnancy rate was associatedwith the presence of DIE (OR=0.24 (95% CI: 0.085-0.7); p=0.009) and the use ofICSI (OR=0.23 (95% CI: 0.07-0.8); p=0.02). A higher pregnancy rate was associatedwith an anti-mullerian hormone (AMH) serum level over 1 ng/ml (OR=4.3 (95% CI:1.1-19); p=0.049). A RP was built to predict pregnancy rate with good calibration [ROCAUC (95% CI) of 0.70 (0.65-0.75)].Conclusion: Our data support that DIE associated with endometrioma in infertilepatients has a negative impact on pregnancy rate after first ICSI-IVF cycle. Furthermore,our predictive model gives couples better information about the likelihood ofconceiving.

Background Blood coagulation plays a crucial role in the blastocyst implantation process and its alteration may be related to in vitro fertilization (IVF) failure. We conducted a prospective observational longitudinal study in women eligible for IVF to explore the association between alterations of coagulation with the IVF outcome and to identify the biomarkers of hypercoagulability which are related with this outcome. Methods Thirty-eight women eligible for IVF (IVF-group) and 30 healthy, age-matched women (control group) were included. In the IVF-group, blood was collected at baseline, 5–8 days after administration of gonadotropin-releasing hormone agonist (GnRH), before and two weeks after administration of human follicular stimulating hormone (FSH). Pregnancy was monitored by measurement of βHCG performed 15 days after embryo transfer. Thrombin generation (TG), minimal tissue factor-triggered whole blood thromboelastometry (ROTEM®), procoagulant phospholipid clotting time (Procoag-PPL®), thrombomodulin (TMa), tissue factor activity (TFa), factor VIII (FVIII), factor von Willebrand (FvW), D-Dimers and fibrinogen were assessed at each time point. Results Positive IVF occurred in 15 women (40%). At baseline, the IVF-group showed significantly increased TG, TFa and TMa and significantly shorter Procoag-PPL versus the control group. After initiation of hormone treatment TG was significantly higher in the IVF-positive as compared to the IVF-negative group. At all studied points, the Procoag-PPL was significantly shorter and the levels of TFa were significantly higher in the IVF-negative group compared to the IVF-positive one. The D-Dimers were higher in the IVF negative as compared to IVF positive group. Multivariate analysis retained the Procoag-PPL and TG as predictors for the IVF outcome. Conclusions Diagnosis of women with hypercoagulability and their stratification to risk of IVF failure using a model based on the Procoag-PPL and TG is a feasible strategy for the optimization of IVF efficiency that needs to be validated in prospective trials.

Deep infiltrating endometriosis (DIE) affects several anatomical locations including the bladder, torus uterinum, uterosacral ligament, rectovaginal septum and bowel. It is the most debilitating form of endometriosis and causes severe pain, digestive and urinary symptoms as well as infertility. Faced with an infertile woman suffering from DIE, the dilemma is whether to opt for first-line IVF treatment or for surgery. In the absence of high-level of evidence from randomized studies, several factors should be taken into account in the decision-making process. The main criterion is whether the patient wants in-vitro fertilization (IVF) treatment or not. Secondly, while previous reports have demonstrated the positive impact of surgery on pregnancy, they also underline the risk of severe complications requiring management in expert centers. Despite the availability of predictive models or scoring systems, the decision mainly boils down to the couple's characteristics. It seems logical to propose first-line IVF when spontaneous fertility is not possible due to associated male infertility or tubal obstruction; for women aged ≥35 years; or in women with diminished ovarian reserve. Conversely, first-line surgery could be the best option for women without these characteristics. However, this strategy is mainly based on low-level of evidence underlining the requiring of randomized trials.

background:Although several scoring systems have been published to evaluate the pregnancy rate after ICSI‐IVF in infertile patients, none of them are applicable for patients with deep infiltrating endometriosis (DIE) nor can they evaluate the chances of pregnancy for individual patients. The aim of this study was to develop a nomogram based on an association of patients’ characteristics to predict the clinical pregnancy rate in patients with endometriosis. methods:This prospective longitudinal study was conducted from January 2007 to June 2010. The nomogram was built from a training cohort of 94 consecutive patients (141 ICSI‐IVF cycles) and tested on an independent validation cohort of 48 patients (83 ICSI‐IVF cycles). DIE was confirmed in all participants. results:The pregnancy rate (per patient) in women with and without DIE was 58 and 83%, respectively (P!0.03). Increased patient age (P!0.04), serum anti-Mullerian hormone (AMH) level!1 ng/ml (P!0.03) and increased number of ICSI‐IVF cycles (P!0.03) were associated with a decreased clinical pregnancy rate. The presence of DIE was the strongest determinant factor of the clinical pregnancy rate in our model [odds ratio!0.26, 95% confidence interval (CI): 0.07‐0.9 (P!0.006)], which also included patient age, serum AMH level and number of attempts at ICSI‐IVF. The nomogram showed an area under the curve (AUC) of 0.76 for the training cohort (95% CI: 0.7‐0.8) and was well calibrated. The AUC for the validation cohort was 0.68 (95% CI: 0.6‐0.75) and calibration was good. conclusions:Our nomogram provides realistic and precise information about ICSI‐IVF success and can be used to guide couples and

Objective To compare the impact of first-line assisted reproductive technology (ART; intracytoplasmic sperm injection [ICSI]-IVF) and first-line colorectal surgery followed by ART on fertility outcomes in women with colorectal endometriosis-associated infertility. Design Retrospective matched cohort study using propensity score (PS) matching (PSM) analysis. Setting University referral centers. Patient(s) A total of 110 women were analyzed from January 2005 to June 2014. A PSM was generated using a logistic regression model based on the age, antimullerian hormone (AMH) serum level, and presence of adenomyosis to compare the treatment strategy. Intervention(s) First-line surgery group followed by ART versus exclusive ART with in situ colorectal endometriosis. Main Outcome Measure(s) After PSM, pregnancy rates (PRs), live-birth rates (LBRs), and cumulative rates (CRs) were estimated. Result(s) After PSM, in the whole population, the total LBR and PR were 35.4% (39/110) and 49% (54/110), respectively. The specific cumulative LBR at the first ICSI-IVF cycle in the first-line surgery group compared with the first-line ART was, respectively, 32.7% versus 13.0%; at the second cycle, 58.9% versus 24.8%; and at the third cycle, 70.6% versus 54.9%. The cumulative LBRs were significantly higher for women who underwent first-line surgery followed by ART compared with first-line ART in the subset of women with good prognosis (age ≤ 35 years and AMH ≥ 2 ng/mL and no adenomyosis) and women with AMH serum level Conclusion(s) First-line surgery may be a good option for women with colorectal endometriosis-associated infertility.

International audience; BACKGROUNDThere is currently no consensus about indications for surgery for infertility associated with colorectal endometriosis. The aim of this study was to evaluate cumulative pregnancy rates (CPRs) after ICSI-IVF cycles in patients with colorectal endometriosis and to identify determinant factors of fertility outcome.METHODSProspective longitudinal multicentre study from January 2005 to June 2011. We included 75 patients with colorectal endometriosis and proved infertility without prior surgery for deep infiltrating endometriosis. Univariable analysis was used to identify determinant factors of pregnancy rate. CPR was calculated using cumulative-incidence methods from log-rank test and Kaplan-Meier curves. For multivariable analysis, Cox proportional hazards model was used.RESULTSFor CPR per patient analysis, the total number of cycles was 113 and the median number of cycles per patient was 1 (range: 1-3). In the whole population the CPR per patient after three ICSI-IVF cycles was 68.6%. The CPR for patients with or without associated adenomyosis was 19 and 82.4%, respectively (P= 0.01). In addition, a patient age over 35 years (P= 0.02) and anti-Mullerian hormone serum level under 2 ng/ml (P= 0.02) were associated with a decreased CPR per patient. At multivariable analysis, adenomyosis [HR = 0.34, 95% CI (0.12-0.99), P= 0.49] was associated with a decreased CPR.CONCLUSIONSOur data confirm that ICSI-IVF offers a high CPR per patient. However, determinant factors of CPR should be taken into account when informing couples of their options.

L’endometriose est une pathologie gynecologique definie par la presence de glandes endometriales et de stroma en dehors de l’uterus (1). Selon les estimations, elle affecterait de 10 a 15 % des femmes en periode de reproduction et atteindrait 40 a 50 % chez les femmes infertiles (2). Des donnees epidemiologiques suggerent une augmentation de l’incidence de l’endometriose du fait de l’impact de facteurs environnementaux (3–5).

This retrospective study of women undergoing IVF (29 with colorectal endometriosis, 157 with tubal factor infertility, and 340 with male factor infertility) found similar fertility outcomes between the groups.

Objective To raise the possibility that pregnancy can be obtained by assisted reproductive techniques in patients with human seminal plasma allergy. Design Case report. Setting University hospital. Patient(s) A woman consulted for a 3-year primary infertility. She reported lack of intercourse because of a seminal plasma allergy. Intervention(s) One intrauterine insemination associated with antihistamine treatment was performed with carefully washed spermatozoa. Result(s) Immediately after the insemination, the patient had an allergic reaction treated by steroids. Fortunately, this single attempt led to a successful pregnancy, and the patient gave birth to a healthy girl. Conclusion(s) Pregnancies can be obtained in patients with seminal plasma hypersensitivity by means of intrauterine insemination. However, serious complications may occur after performing intrauterine insemination, which is not a totally reliable method to prevent an allergic reaction. Thus a multidisciplinary team should follow such patients carefully and watch for the potential risks and side effects. In vitro fertilization may represent the more cautious option.

Introduction Women undergoing assisted reproductive techniques (ART) are given gonadotrophins to promote the development of multiple follicles within their ovaries. This treatment may be associated with a risk of ovarian hyperstimulation syndrome and venous or arterial thrombosis. The association of clinical and biological criteria of hypercoagulability might contribute to the identification of patients at risk and probably could predict success of ART. The aim of this study was to evaluate thrombin generation, thrombomodulin activity, tissue factor (TF) activity, and procoagulant phospholipids in selected women undergoing ART. We also assessed the potential correlation between the levels of the studied biomarkers and the outcome of the ART. Material and Method A cohort of 27 infertile women eligible for ART and 30 healthy age matched women was studied. All patients were Caucasian aged 33.75 ± 3.52 years and weight 61.08 ± 8.10 kg. Women included in the study did not present any personal or family history of VTE or known thrombophilia. They did not present any signs of hemorrhagic syndrome and did not suffer from any known autoimmune disease. Blood samples were taken under fasting conditions at the following time-points: at the inclusion (T0), between the 5th and 8th day of ovarian stimulation with gonadotrophines (T1) and at the day of HCG administration (T2). Thrombin generation (TG) in plasma was assessed using the Calibrated Automated Thrombogram assay (using, PPP-Reagent-5pM TF from Diagnostica Stago, France), Plasma levels of thrombomodulin activity (TMa), and TF activity (TFa) were measured by home-made tests, Procoagulant phospholipids (PPL) dependent clotting time was measured using a factor Xa-based assay (STA-R Procoag-PPL, Diagnostica Stago, France). Results The endogenous thrombin potential (ETP), PPL, TMa and TFa were significantly higher in the ART-T0 group as compared to the control group. At ART-T2 a significant increase of TG was observed as compared to ART-T0. At ART-T0 44.5%, 44.4 % and 33.3 % of women had ETP, TFa and TMa higher than the Upper Normal Limit respectively (UNL = mean+2 S.D.). Among with negative ART 89% and 91.7% showed TMa and TFa levels > UNL at ART-T0. At T1 50% of women had a least one parameter of TG higher than the UNL. At ART T2 65.2 % of women had TG > UNL. At the same time, 87.5% and 83.4% of women with negative ART had levels of TMa and TFa > UNL. Conclusion This study analyzed the profile of thrombin generation in infertile women eligible for ART and investigated the influence of hormone treatment with gonadotropins and HCG on TG and levels of TMa and TFa. Hypercoagulability, in terms of increased ETP is present in 46% of infertile women eligible for ART. These women remain in a hypercoagulable state throughout the entire period of hormone treatment. The most significant finding of this study was that 33% of patients show a value superior to the UNL for thrombomodulin and 45% for tissue factor. Interestingly 89%of women with negative ART had TMa higher than the UNL. Respectively 91% of women with negative ART had TFa levels higher than the UNL Disclosures: No relevant conflicts of interest to declare.

Oocyte donation is a medically assisted reproduction technique defined by the law on bioethics, which will be updated in 2018. The use of this technic is currently growing in France. The aim of our study was to identify the factors related to oocyte donation which significantly impact the establishment of the mother-child bond during postpartum.We organized five semi-structured interviews with primiparous mothers after a pregnancy following an oocyte donation at the hospital of Tenon, in Paris.Our results allowed us to advance that the factors related to oocyte donation would not significantly influence the establishment of the mother-child bond during post-partum : it is above all the singular history of every patient that matters. An analysis on a larger population would be necessary to confirm our results.; Le don d’ovocyte est une technique d’assistance médicale à la procréation encadrée par la loi de bioéthique, qui sera mise à jour courant 2018. Cette technique se développe actuellement en France. L’objectif de notre étude était d’identifier les facteurs relatifs au don d’ovocyte qui influenceraient de manière décisive la mise en place du lien mère-enfant durant le post-partum.Nous avons réalisé cinq entretiens semi-directifs avec des mères primipares après une grossesse issue d’un don d’ovocyte réalisé à l’hôpital Tenon à Paris.Nos résultats ont permis d'avancer que les facteurs relatifs au don d’ovocyte n’influenceraient pas de manière décisive la mise en place du lien mère-enfant dans le postpartum : c’est avant tout l’histoire singulière de chaque patiente qui semblait déterminante.Une analyse sur une population plus large serait nécessaire pour confirmer ces résultats issus d’un échantillon restreint.
