[First-line management of infertile couple. Guidelines for clinical practice of the French College of Obstetricians and Gynecologists 2022]. / Prise en charge de première intention du couple infertile : mise à jour des RPC 2010 du CNGOF.

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.

Is it useful to measure DHEAS levels in PCOS?

INTRODUCTION: A high prevalence of increased DHEAS (dehydroepiandrosterone sulfate) levels (about a third of cases) has been reported in women with polycystic ovary syndrome (PCOS). This excess of adrenal androgens remains a mystery in this ovarian pathology. It is well known that DHEAS production correlates negatively with age, and study populations of women with PCOS are generally young. To avoid this bias, a study was carried out on a large population of women with PCOS and control women, using normal DHEAS values for each age group, to better assess prevalence and better understand the link between PCOS and DHEAS. METHODS: A retrospective cross-sectional study was conducted at the Lille University Hospital. A total of 1223 patients with PCOS according to the Rotterdam criteria and 517 control women were included. DHEAS elevation was diagnosed according to the standards of the Lille University Hospital Institute of Biochemistry and Molecular Biology, based on patient age. The prevalence of increased serum DHEAS levels was calculated in each population and according to PCOS phenotype. Correlations were assessed between serum DHEAS levels and clinical, hormonal, and metabolic markers, with adjustment for age. RESULTS: Prevalence of increased DHEAS was significantly higher in the PCOS group than in the control group (8.1 vs. 4.3%; OR=1.98 (95%CI: 1.23-3.19), P=0.005, and OR=1.07 (95%CI: 1.05-1.09), P=0.014 without and with adjustment for BMI respectively), and in phenotypes A and C than in controls (OR=2.88 (95%CI: 1.76 to 4.72), P<0.001 and OR=2.81 (95%CI: 1.39 to 5.67), P=0.004 respectively), but not in phenotype D. A correlation was found between DHEAS level and total testosteronemia (r=0.34, P<0.001), androstenedione (r=0.24, P<0.001), 17 hydroxyprogesteronemia (r=0.22, P<0.001) and age (r=0.25, P<0.001). No correlations were found with AMH, LH or FSH, and a very weak positive correlation was found with BMI (r=0.15; P<0.001). CONCLUSION: Using age-dependent norms, DHEAS elevation was found in only 8.1% of women with PCOS (11% in the case of phenotypes A and C) versus 4.3% in controls and women with phenotype D. DHEAS levels correlated only with other androgens, and not (or only minimally) with other ovarian, pituitary or metabolic markers. DHEAS assay therefore appears to be of no interest for positive diagnosis or understanding of the pathophysiology of PCOS, except in case of very high testosterone levels.

Does surgery for colorectal endometriosis prior to IVF±ICSI have an impact on cumulative live birth rates?

RESEARCH QUESTION: Does colorectal endometriosis surgery prior to IVF ± intracytoplasmic sperm injection (ICSI) impact cumulative live birth rates? DESIGN: This retrospective, monocentric study (Lille University Hospital) was conducted between 1 January 2007 and 31 December 2018. Two groups of patients from the JFIV database were included: a group undergoing IVF±ICSI alone (120 patients, 215 oocyte retrievals), and a group undergoing surgery and then IVF±ICSI (69 patients, 109 oocyte retrievals). The mode of management was decided after a multidisciplinary team meeting. Different criteria such as age (cut-off 35 years), anti-Müllerian hormone concentration (cut off 2 ng/ml), imaging results and the patient's symptomatology were considered: the most symptomatic patients underwent surgery prior to IVF±ICSI. The cumulative clinical pregnancy and live birth rates obtained after four IVF attempts were estimated and compared between the two groups using competing risk survival methods. RESULTS: The cumulative live birth rates after four IVF attempts in the two groups were not statistically significantly different (50.8% in the IVF±ICSI group versus 52.2% in the surgery followed by IVF±ICSI group, P = 0.43). The results for the cumulative clinical pregnancy rates were the same (56.7% in the IVF±ICSI group versus 58% in the surgery followed by IVF±ICSI group, P = 0.47). CONCLUSION: The study shows that cumulative live birth and pregnancy rates were similar in infertile patients with colorectal endometriosis who underwent IVF±ICSI either with or without prior colorectal endometriosis surgery.

Results and perinatal outcomes from 189 ICSI cycles of couples with asthenozoospermic men and flagellar defects assessed by transmission electron microscopy.

RESEARCH QUESTION: Do patients presenting with flagella ultrastructural defects as assessed by electron microscopy, and defined within three phenotypes (dysplasia of the fibrous sheath [DFS], primary flagellar dyskinesia [PFD] and non-specific flagellar abnormalities [NSFA]), have decreased chances of success in intracytoplasmic sperm injection (ICSI) or adverse obstetric and neonatal outcomes? DESIGN: Retrospective analysis of 189 ICSI cycles from 80 men with spermatozoa flagellum ultrastructural defects (DFS [n = 16]; PFD [n = 14]; NSFA [n = 50] compared with a control group (n = 97). Cycles were cumulatively analysed. All fresh and frozen embryo transfers resulting from each ICSI attempt were included. The effect of transmission electron microscopy (TEM) phenotype on the main ICSI outcomes was assessed by a multivariate logistic regression combined with a generalized linear mixed model to account for the non-independence of the observations. RESULTS: No predictive value of TEM phenotype was found on the main outcomes of ICSI, namely fertilization rates, pregnancy and delivery rates, and cumulative pregnancy and delivery rates. Cumulative pregnancy rates ranged from 29.0-43.3% in the different TEM phenotype subgroups compared with 36.8% in the control group. Cumulative live birth rates ranged from 24.6-36.7% compared with 31.4% in the control group. No increase was found in miscarriages, preterm births, low birth weights or birth abnormalities. CONCLUSIONS: Data on the cumulative chances of success in ICSI of patients with ultrastructural flagellar defects, a rare cause of male infertility often associated with an underlying genetic cause, are reassuring, as are obstetrical and neonatal outcomes in this population.

Association between endometriosis, infertility and autoimmune antiplatelet glycoprotein VI antibodies in two patients.

The association between endometriosis and autoimmune diseases is well known, however no acquired platelet function defect has been described so far. We describe the case of two patients with endometriosis associated with an antiplatelet glycoprotein VI (anti-GPVI) antibody. The two women with deep pelvic endometriosis associated with secondary infertility presented a mild bleeding tendency, a deficient platelet aggregation response to collagen, convulxin or CRP and a severe GPVI deficiency. Immunoblot revealed a combined FcRγ deficiency but no indication of GPVI cleavage. In the first case, platelet count was normal and an anti-GPVI IgG was detected in plasma. A first corticosteroids administration normalized in vitro platelet functions but further administrations were unsuccessful. Three IVF attempts failed. Conservative laparoscopic surgery was carried out after antifibrinolytic treatment without bleeding. The second case presented with a history of moderate thrombocytopenia and a weak anti-GPVI in the context of infertility and autoimmune disease, the Sjögren syndrome resolved after corticosteroids and hydroxychloroquine treatment. Acquired GPVI deficiencies are rare. It would be useful to determine whether the association with endometriosis is coincidental or not by more systematic investigations. It does not seem that in these patients, GPVI deficiency is associated with an increased risk of bleeding.

What is the context? • Evidence for an immune system dysfunction is reported in endometriosis and the association between endometriosis and autoimmune diseases is well known.• No autoimmune platelet function defect has been described so far.What is new?• We report two unrelated patients with endometriosis-associated infertility presenting a platelet glycoprotein VI deficiency due to an autoantibody.• In both cases, a deficient platelet aggregation response to collagen, convulxin or CRP and a severe GPVI deficiency were observed.• Immunoblot revealed no indication of GPVI cleavage.What is the impact? • Our observation raises the question whether GPVI could be a preferential target for the development of anti-GPVI autoantibodies associated with endometriosis.• It does not seem that in these patients, GPVI deficiency is associated with an increased risk of severe bleeding disorder.

Serum LH levels are associated to serum insulin and Anti-Müllerian hormone levels in women with both functional hypothalamic amenorrhoea and polycystic ovarian morphology.

OBJECTIVE: The aim of the study was to investigate whether serum Luteinizing Hormone (LH) levels in women with Functional Hypothalamic Amenorrhoea (FHA) and Polycystic Ovarian Morphology (PCOM) are still associated to Body Mass Index (BMI) and/or serum insulin and/or Anti-Müllerian Hormone (AMH) levels using a larger population of FHA. DESIGN: Retrospective observational study (2006-2020). PARTICIPANTS: Data from 62 FHA patients were used for this study using strict criteria to define them. MEASUREMENTS: Serum LH, FSH, 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulphate (DHEA-S), androstenedione, total testosterone, prolactin, Sex Hormone Binding Globulin (SHBG) and AMH levels were measured by immunoassay. To homogenize the AMH values, we converted those obtained after 2015. We defined PCOM with strict criteria: a follicle number per ovary (FNPO) ≥12 or ≥20 per ovary, depending on the date on which the assessment was carried out and the ultrasound device. RESULTS: Forty-two percentage of our FHA population had PCOM. The PCOM+ group had significantly higher ranks of BMI (p = .024) and serum AMH levels (p = .0001) and significantly lower ranks of serum FSH levels (p = .002). LH was positively correlated with fasting insulin (p = .011) and with AMH (p = .035) in the PCOM+ group only but not with BMI. There was a positive correlation between LH and FSH in both groups. CONCLUSION: Our study suggests that GnRH insufficiency in women with PCOM unravels some mechanisms of LH regulation that are poorly documented in the literature and may involve a direct pituitary effect, as suggested by our results with serum insulin and AMH levels.

Comparison of two endometrial preparation methods for frozen-thawed embryo transfer in anovulatory PCOS patients: Impact on miscarriage rate.

OBJECTIVE: Some studies have suggested that patients with polycystic ovary syndrome (PCOS) are at high risk of miscarriage. However, this still remains controversial. Several potential factors might explain this association: obesity, hyperinsulinemia and hyperandrogenism. Artificial and stimulated cycles appear to be comparable for endometrial preparation in frozen-thawed embryo transfer (FET) in PCOS patients. Only a few studies have assessed miscarriage rates specifically in PCOS. We have evaluated the impact of endometrial preparation on FET outcomes in anovulatory PCOS patients. METHODS: A retrospective cohort study was conducted at the Lille University Hospital, including 255 FET cycles in 134 PCOS patients between January 2011 and December 2017. PCOS was defined by the presence of at least two of the three Rotterdam's criteria. Patients were under 35 years old. Two endometrial preparation protocol were studied: stimulated cycle (gonadotropins on the second day of the cycle and luteal phase support including natural progesterone 600 mg/day) and artificial cycle (6 mg oral estradiol valerate and 800 mg micronized vaginal progesterone daily). RESULTS: 137 FET were performed under stimulated cycle and 118 FET under artificial cycle. Early pregnancy rates (30% versus 37.3%, p = NS), miscarriage rates (22% versus 25%, p = NS) and live birth rates (23.4% versus 26.3%, p = NS) were similar. CONCLUSIONS: In anovulatory PCOS women, the type of endometrial preparation does not influence FET outcomes, specifically regarding the miscarriage rate.

Polycystic ovary syndrome phenotype does not have impact on oocyte morphology.

PURPOSE: The primary objective of the present study of women participating in an ICSI program was to determine whether the morphologic quality of oocytes was related to the polycystic ovary syndrome (PCOS) phenotype. METHODS: We performed a retrospective cohort study in the IVF unit at the Lille University Medical Center (Lille, France) between 2006 and 2015. Oocyte morphology (fragmented first polar body, abnormal zona pellucida, large perivitelline space, material in perivitelline space, abnormal shape of oocyte, granular cytoplasm and intracytoplasmic vacuoles) was evaluated in PCOS women and according to different subgroup (depending on the presence or absence of the cardinal features polycystic ovarian morphology (PCOM), hyperandrogenism (HA), and oligo-anovulation (OA)). RESULTS: A total of 1496 metaphase II oocytes (n = 602 for phenotype A combining PCOM + HA + OA, n = 462 oocytes for phenotype C: PCOM + HA, and n = 432 for phenotype D: PCOM + OA) were assessed. The phenotypes A, C and D did not differ significantly with regard to the proportion of normal oocytes (adjusted percentages (95%CI): 35.2% (31.5 to 39.1%), 25.8% (21.9 to 29.9%) and 34.0% (29.7 to 38.6%), respectively: adjusted p = 0.13). Likewise, there were no significant intergroup differences in oocyte morphology. The ICSI outcome was not significantly associated with the PCOS phenotype. CONCLUSION: The present study is the first to show that the PCOS phenotype (notably the presence vs. absence of OA and/or HA) is not significantly associated with the morphological quality of oocytes.

Systematic use of long-acting intramuscular progesterone in addition to oral dydrogesterone as luteal phase support for single fresh blastocyst transfer: A pilot study.

Objective: The need of luteal support after FET is no longer to be proven. Different routes of progesterone administration are available with interindividual differences in metabolization and serum progesterone levels, the latter being highly correlated with pregnancy and delivery rates. The administration of 2 different routes of progestogen significantly improves success rates in FET. The aim of the current study was to investigate the added value to combine intramuscular administration of progesterone to dydrogesterone in fresh embryo transfer. Methods: This is a retrospective study from prospectively collected data. Patient, aged between 18 and 43 years old, had received a fresh blastocyst transfer between January 2021 and June 2021. In the first group, all patients received only oral dydrogesterone 10mg, three times a day, beginning the evening of oocyte retrieval. In the second group, patients received, in addition to dydrogesterone, a weekly intramuscular injection of progesterone started the day of embryo transfer. Primary endpoint was ongoing pregnancy rate. Results: 171 fresh single blastocyst transfers have been performed during this period. 82 patients were included in "dydrogesterone only" and 89 patients in "dydrogesterone + IM". Our two groups were comparable except for body mass index. After adjustment on BMI, our two groups were comparable regarding implantation rate, early pregnancy rate (46.1 versus 54.9, OR 1.44 [0.78; 2.67], p=0.25) miscarriage rate, ongoing pregnancy rate (30.3 versus 43.9, OR 1.85 [0.97; 3.53] p= 0.06). Conclusion: Using systematically long acting intramuscular progesterone injection in addition to oral dydrogesterone as luteal phase support seems to have no significant impact on IVF outcomes when a single fresh blastocyst transfer is performed.

Impact of endometriosis on oocyte morphology in IVF-ICSI: retrospective study of a cohort of more than 6000 mature oocytes.

BACKGROUND: Infertility associated with endometriosis can be explained by several non-exclusive mechanisms. The oocyte plays a crucial role in determining embryonic competence and this is particularly relevant for in vitro fertilization (IVF) outcomes. According to some authors, the morphology of oocytes could also be a non-invasive marker of oocyte quality. The aim of this study was to evaluate the relationship between endometriosis and oocyte morphology after controlled ovarian stimulation for intracytoplasmic sperm injection (ICSI) on a large oocyte cohort. METHODS: Single-center comparative retrospective study in the academic In Vitro Fertilization (IVF) unit of the Lille University Hospital. A total of 596 women treated for IVF-ICSI with ejaculated spermatozoa for sperm alterations were included. They were classified as endometriosis (n = 175) or control groups (n = 401). The morphological evaluation of 2,016 mature oocytes from 348 cycles of patients with endometriosis was compared with that of 4,073 mature oocytes from 576 control cycles. The main outcome measures were Average Oocyte Quality Index (AOQI) and metaphase II oocyte morphological scoring system (MOMS). Comparison of groups was carried out by a mixed linear model and by a generalized estimation equation model with a "patient" random effect to consider that a patient might have several attempts. RESULTS: No difference in AOQI and MOMS scores was found between endometriosis and control women (adjusted p = 0.084 and 0.053, respectively). In case of endometriosis, there were significantly fewer metaphase II oocytes retrieved, embryos obtained, grade 1 embryos and number of cumulative clinical pregnancies compared to controls. In the endometriosis group, endometriosis surgery was associated with a reduced number of mature oocytes retrieved, and the presence of endometrioma(s) was associated with some abnormal oocyte shapes. Nevertheless, no difference concerning the AOQI and MOMS scores was found in these subgroups. CONCLUSION: Endometriosis does not have a negative impact on oocytes' morphology in IVF-ICSI. TRIAL REGISTRATION: On December 16, 2019, the Institutional Review Board of the Lille University Hospital gave unrestricted approval for the anonymous use of all patients' clinical, hormonal and ultrasound records (reference DEC20150715-0002).

Could Cytochrome P450 2D6, 3A4 and 3A5 Polymorphisms Explain the Variability in Clinical Response to Clomiphene Citrate of Anovulatory PCOS Women?

Introduction: Cytochrome P450 2D6, 3A4 and 3A5 are involved in the metabolism of many drugs. These enzymes have a genetic polymorphism responsible for different metabolic phenotypes. They play a role in the metabolism of clomiphene citrate (CC), which is used to induce ovulation. Response to CC treatment is variable, and no predictive factors have thus far been identified. Objective: To study a possible link between the cytochrome P450 2D6, 3A4 and 3A5 polymorphisms and clinical response to CC. Study Design: Seventy-seven women with anovulatory Polycystic Ovarian Syndrome (PCOS) treated with CC were included which determined their cytochrome P450 2D6, 3A4 and 3A5 genotypes and used the results to predict ovarian response to this drug. Predicted responses based on the cytochrome genotypes were compared with the observed clinical responses using the calculation of a weighted Kappa coefficient. Main Outcome Measures: Number of dominant follicles assessed by ultrasound at the end of the follicular phase and confirmation of ovulation by blood progesterone assay in the luteal phase. Results: Concordance between the predicted and observed responses for the combination of the three cytochromes was 36.71%, with a negative Kappa coefficient (K = -0.0240), which corresponds to a major disagreement. Similarly, for predictions based on the cytochrome P450 2D6 genotype alone, only 39.24% of predictions were verified (coefficient K = -0.0609). Conclusion: The genetic polymorphism of cytochromes P450 2D6, 3A4 and 3A5 does not appear to influence clinical response to CC used to induce ovulation in anovulatory PCOS women.

Anti-Müllerian hormone as a driving force of polycystic ovary syndrome, independently from insulin resistance.

RESEARCH QUESTION: Which clinical features, along with biological features, ultrasound features, or both, are the most strongly associated with either high or low anti-Müllerian hormone (AMH) levels in patients with polycystic ovary syndrome (PCOS)? DESIGN: A retrospective cross-sectional study conducted within a university-affiliated reproductive endocrinology unit in Lille, France. A total of 639 patients with PCOS according to the Rotterdam Criteria and 137 control women were included. A comparison of clinical, hormonal, metabolic and ultrasound data in patients with PCOS and controls belonging to the first (Q1) and fourth (Q4) quartiles of their respective AMH ranges (discriminant analysis) was conducted. RESULTS: In the PCOS group, patients in Q4 had higher LH levels and a more severe phenotype, but they were thinner and had lower levels of hyperinsulinaemia than patients in Q1. In the PCOS group, discriminant analysis yielded a highly significant model in which follicle number per ovary (FNPO) and serum LH were strongly and equally discriminating between Q4 and Q1 (R2 at 0.371 and 0.304, respectively, both P < 0.0001), whereas body mass index had less, although significant, effect (R2 = 0.075, P < 0.0001). In control women, discriminant analysis yielded a significant discriminant model, including only FNPO and age (R2 at 0.62 and 0.27, both P < 0.0001). CONCLUSION: High serum AMH levels are associated with high serum LH levels and more severe features of PCOS. Conversely, the effect of hyperinsulinism may be greater in patients with lower serum AMH levels, suggesting independent effects of AMH and insulin on the phenotypic expression of PCOS.

Revisiting the serum level of anti-Müllerian hormone in patients with functional hypothalamic anovulation.

STUDY QUESTION: Are serum levels of anti-Müllerian hormone (AMH) normal in patients with functional hypothalamic anovulation (FHA)? SUMMARY ANSWER: Our study confirms that in the general FHA population, serum AMH levels are not decreased, but if patients with polycystic ovarian morphology (PCOM) are excluded, levels become significantly lower, as in other situations of gonadotropic insufficiency. WHAT IS KNOWN ALREADY: In most situations of low LH (physiological, pharmacological or pathological), serum AMH levels are low. However, paradoxically, many publications have reported normal or even increased serum AMH levels in FHA patients. STUDY DESIGN, SIZE, DURATION: Retrospective observational study conducted in an academic centre. The data concerning the study population was collected between 2006 and 2015 from a database including clinical, biological and ultrasound information. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 45 FHA patients were compared to 37 controls matched based on age and body mass index (BMI). Serum LH, FSH, androstenedione, total testosterone, prolactin and AMH levels were measured by immunoassay. We defined PCOM with strict criteria: a follicle number per ovary (FNPO) ≥ 12 or ≥ 19 per ovary, depending on the date on which the assessment was carried out and the ultrasound device. An AMH level ≥ 35 pmol/l could be a substitute for an excess FNPO. Controls meeting these criteria were not included in this study. MAIN RESULTS AND THE ROLE OF CHANCE: There was no significant difference in the ranges of AMH levels between FHA and controls. Using strict criteria to define PCOM status, 46.7% of FHA patients had PCOM. After excluding these patients, the levels of AMH were significantly lower (P < 0.002) in FHA patients compared to controls. Within the FHA group, patients with PCOM had significantly higher ranks of AMH levels and BMI than those without PCOM. However, within the PCOM+ subgroup, the ranks of LH, FSH and A levels were still lower than in controls (P < 0.0001, <0.002 and <0.05, respectively). The positive correlation between AMH and LH was significant in the controls but not in the FHA group. However, in the FHA PCOM+, there was a strong positive correlation between BMI and LH. LIMITATIONS, REASONS FOR CAUTION: This is a retrospective study; our controls did not represent the general population as they were recruited in an ART centre; we used a modified classification for PCOM using follicle count and/or AMH level with in-house thresholds to define the follicle excess; the AMH assay used is no longer commercially available. WIDER IMPLICATIONS OF THE FINDINGS: Besides biasing the results of AMH assay in FHA patients, the presence of PCOM in FHA patients despite low gonadotropin and androgen levels raises the issue of epigenetically acquired amplification of androgen and/or FSH sensitivity within granulosa cells from polycystic ovaries. In terms of clinical practice, it seems important not to diagnose a low ovarian reserve in FHA patients too quickly on the basis of a decreased AMH level alone. On the contrary, a high AMH level in the context of a menstrual disorder and PCOM should not lead to a misdiagnosis of polycystic ovary syndrome (PCOS) if the basal LH is low. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: N/A.

[AFU and SALF recommendations for the evaluation of male infertility]. / Recommandations de l'AFU et de la SALF concernant l'évaluation de l'homme infertile.

BACKGROUND: The aim of these Association Française d'Urologie (AFU) and Société d'Andrologie de Langue Française (SALF) common recommendations are to provide practice guidelines for the French Urological and Andrological community regarding the evaluation of infertile men. MATERIAL AND METHODS: Literature search in PubMed using the keywords "male infertility", "diagnosis", "management" and "evaluation" limited to clinical articles in English and French prior to 1/01/2020. To inform the level of evidence, the HAS grading system (2013) was applied. RESULTS: Concerning the evaluation of infertile men, the AFU and the SALF recommend : (1) a systematic interview exploring the family history, the fertility history of the man outside the couple, the patient's personal history that may have an impact on his fertility, lifestyle habits, treatments, symptoms and possible sexual difficulties of the couple; (2) a general physical examination to assess signs of hypogonadism and secondary sexual characters; (3) a scrotal physical examination performed by an urologist or andrologist to assess (i) the testes for volume and consistency, (ii) vas deferens and epididymes for total or partial absence or nodules, and (iii) presence of varicoceles; (4) Performing two semen analyses, according to World Health Organization guidelines, if the first one has at least one abnormaly; (5) a scrotal ultrasound as part of routine investigation, that can be completed with an endorectal pelvic ultrasound according to the clinic; (6) an endocrine evaluation with at least a Testosterone and FSH serum determination; (7) Karyotype analysis in infertile men with a sperm concentration ≤10 106/mL; (8) assessment of Yq microdeletions in infertile men with a sperm concentration ≤1 106/mL; (9) Cystic fibrosis transmembrane conductance regulator gene evaluation in case of suspicion for bilateral or unilateral congenital agenesis of vas deferens and seminal vesicles. The interest of tests analyzing DNA fragmentation (TUNEL, SCSA) is still under investigation. CONCLUSION: These guidelines can be applied in routine clinical practice in all infertile men.

Role of Anti-Müllerian Hormone in the Pathogenesis of Polycystic Ovary Syndrome.

Besides its interest for diagnosis, the finding of an elevated serum AMH level in PCOS has open major pathophysiological issues. This review addresses the three most important issues: 1- the role of AMH in the disturbed folliculogenesis of PCOS; 2- the role of AMH in the gonadotropin dysregulation of PCOS and 3- the role of AMH in the trans-generational transmission of PCOS. For each of those issues, the clinical and experimental evidences currently available are discussed and pathophysiological hypothesis are proposed.

Fertiloscopy in women with unexplained infertility: Long-term cumulative pregnancy rate.

OBJECTIVE: Fertiloscopy is as safe as laparoscopy in literature, but we don't know its relevance in women with unexplained infertility (UI). Our objective was to assess the effects of fertiloscopy procedures on the outcomes of subsequent pregnancy occurrences in patients with UI. METHODS: Retrospective, single-center study of all patients followed up after fertiloscopy procedures between 2002 and 2007. The occurrence and outcome of pregnancies were studied in the five years following the procedure. RESULTS: 124 fertiloscopies were performed. Pelvic exploration was considered as sufficient in 83.8% of cases, of which no abnormalities were found in 78.2%. Laparoconversions occurred for 19 patients (16.5%). The pregnancy rate at five years was 76.9%. The mean delay for pregnancy occurrence was 10.7 months (±17). CONCLUSION: The pregnancy rate in our study is similar to that after laparoscopy. Fertiloscopy, a less intrusive procedure, should be considered as a reliable option for the management of patients with UI.

Clinical Practice Guidelines for Childbearing Female Candidates for Bariatric Surgery, Pregnancy, and Post-partum Management After Bariatric Surgery.

Emerging evidence suggests that bariatric surgery improves pregnancy outcomes of women with obesity by reducing the rates of gestational diabetes, pregnancy-induced hypertension, and macrosomia. However, it is associated with an increased risk of a small-for-gestational-age fetus and prematurity. Based on the work of a multidisciplinary task force, we propose clinical practice recommendations for pregnancy management following bariatric surgery. They are derived from a comprehensive review of the literature, existing guidelines, and expert opinion covering the preferred type of surgery for women of childbearing age, timing between surgery and pregnancy, contraception, systematic nutritional support and management of nutritional deficiencies, screening and management of gestational diabetes, weight gain during pregnancy, gastric banding management, surgical emergencies, obstetrical management, and specific care in the postpartum period and for newborns.

PCOS and Hyperprolactinemia: what do we know in 2019?

Polycystic ovary syndrome (PCOS) and hyperprolactinemia (HPRL) are the two most common etiologies of anovulation in women. Since the 1950s, some authors think that there is a pathophysiological link between PCOS and HPRL. Since then, many authors have speculated about the link between these two endocrine entities, but no hypothesis proposed so far could ever be confirmed. Furthermore, PCOS and HPRL are frequent endocrine diseases and a fortuitous association cannot be excluded. The evolution of knowledge about PCOS and HPRL shows that studies conducted before the 2000s are obsolete given current knowledge. Indeed, most of the studies were conducted before consensual diagnosis criteria of PCOS and included small numbers of patients. In addition, the investigation of HPRL in these studies relied on obsolete methods and did not look for the presence of macroprolactinemia. It is therefore possible that HPRL that has been attributed to PCOS corresponded in fact to macroprolactinemia or to pituitary microadenomas of small sizes that could not be detected with the imaging methods of the time. Recent studies that have conducted a rigorous etiological investigation show that HPRL found in PCOS correspond either to non-permanent increase of prolactin levels, to macroprolactinemia or to other etiologies. None of this recent study found HPRL related to PCOS in these patients. Thus, the link between PCOS and HPRL seems to be more of a myth than a well-established medical reality and we believe that the discovery of an HPRL in a PCOS patient needs a standard etiological investigation of HPRL.
