RESUMO

STUDY QUESTION: What are the changes in serum concentration of total and cleaved anti-Muüllerian hormone (AMH) molecular forms and of androgens before and throughout pregnancy in women with and without polycystic ovary syndrome (PCOS) in a longitudinal follow-up investigation? SUMMARY ANSWER: Serum levels of total and cleaved AMH are higher from preconception to the third trimester of pregnancy in women with PCOS as compared to controls, whereas testosterone and androstenedione levels are higher in women with PCOS than in control women before pregnancy and during the second and third trimester of pregnancy. WHAT IS KNOWN ALREADY: Cross-sectional or partial longitudinal studies have shown higher AMH and androgen levels in pregnant women with PCOS as compared with non-PCOS women. To date, no complete longitudinal dynamic monitoring of the circulating forms of AMH and androgens from pre-conception to the third trimester of pregnancy have compared women with and without PCOS. STUDY DESIGN, SIZE, DURATION: This systematic prospective quarterly longitudinal monocentric study was a comparative follow-up of 30 women with PCOS and 29 controls before and during pregnancy from April 2019 to July 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women aged 18-43 years with a pre-conception measurement of AMH were included during the first trimester of a singleton pregnancy. The PCOS group was defined according to the Rotterdam diagnostic criteria. The control group patients included in the study had normal ovarian reserves. Circulating total and cleaved AMH, and serum estradiol, LH, and androgen levels were measured during the first, second, and third trimester of pregnancy in all study participants. MAIN RESULTS AND THE ROLE OF CHANCE: Before pregnancy, patients with PCOS had higher levels of AMH than controls. The total and cleaved AMH forms were significantly higher in women with PCOS than controls from pre-conception to the third trimester of pregnancy (all P < 0.001). Androgens (total testosterone and androstenedione) were higher in women with PCOS than controls from mid-pregnancy onwards. LIMITATIONS, REASONS FOR CAUTION: Our control population was a population of infertile women with no ovarian problems but most of them had undergone ART treatments to achieve pregnancy. WIDER IMPLICATIONS OF THE FINDINGS: These results strengthen the hypothesis that gestational hyperandrogenism as well as exposure to elevated AMH levels in utero could be driving forces predisposing female progeny to develop PCOS. STUDY FUNDING/COMPETING INTEREST(S): Funding was provided by INSERM, France (grant number U1172) and the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program, ERC-2016-CoG to P.G. grant agreement n° 725149/REPRODAMH. The authors have nothing to declare. TRIAL REGISTRATION NUMBER: NCT03483792.

RESUMO

The use of hormone replacement therapy (HRT) for menopausal women has been the subject of much controversy in recent years, particularly concerning the carcinologic risks. The purpose of this review is to evaluate the impact of the use of HRT on the risk of gynecological but also extra-gynecological cancers. The effect of the type and the duration of use of HRT in menopausal women will also be discussed. The beneficial impact of HRT on overall mortality is also an element that will be discussed and must be taken into account when evaluating the benefit-risk balance of HRT for menopausal women.

RESUMO

BACKGROUND: Most studies evaluating career aspirations among gender are performed in Anglo-Saxon countries. Two recent French studies looked at the career choice of residents in obstetrics & gynecology. It seemed useful to us to broaden this questioning to other specialties, by proposing a study to all residents in the same Faculty. The objective of our study was to describe residents' career aspirations and possible barriers according to gender. METHODS: Declarative cross-sectional survey, using questionnaires sent by email to the specialty residents of the Faculty of Medicine of Lille (France). An analysis by specialty group (i.e., medicine, surgery, obstetrics & gynecology, and anesthesia & resuscitation) and a comparison of the results according to gender were performed. RESULTS: Of the 1384 specialty residents currently in training, 462 answered the questionnaire (33.38%), among whom 289 women and 173 men (average age = 27.08 ± 0.091 years). Seventeen women (5.9%) were currently considering a university hospital career versus 37 men (21.4%) (p = 0.001). Gender analysis made it possible to identify obstacles to engaging in a university career: lacking a female model, more frequent doubting the ability to undertake this type of career among women (61.6%) than men (35.3%) (p < 0.001), and gender discrimination felt in the workplace for 51.6% of women (versus 7.5% of men, p < 0.001). Subgroup analysis showed specificities related to each specialty. CONCLUSIONS: Few residents plan to embark upon a university hospital career, let alone female residents. There are considerations specific to each specialty and marked gender differences regarding career aspirations. Many features have been identified as obstacles to access to university hospital positions for women. It is important to develop strategies to remove these barriers and enable women to pursue such university careers. TRIAL REGISTRATION: Not applicable (no intervention).

RESUMO

BACKGROUND: Maternal virilization during pregnancy is a rare phenomenon. Polycystic ovary syndrome (PCOS), luteoma and luteinic cysts are the most frequent and benign etiologies. This article presents two cases of recurrent maternal virilization during pregnancy. CLINICAL CASES: Our reported cases were young women with Afro-Caribbean and Nigerian origins. Data were collected by history-taking, clinical examination, laboratory investigations, transabdominal ultrasonographic examination and Magnetic Resonance Imaging. Both patients were diagnosed with PCOS according to the Rotterdam criteria. During each of their pregnancies they both developed an explosive hirsutism, a deepening in the voice, a clitoromegaly. Gestational diabetes occurred during pregnancies. There was no fetal virilization, despite raising androgen levels, more than tenfold to normal. Improvement of hirsutism and normalization of androgens were described in postpartum. CONCLUSION: Only few cases of maternal virilization during pregnancy were reported in literature and even fewer concern recurrent and bilateral ovarian etiology. Hyperplasia of ovarian theca cells seems to be the most likely explanation, which would suggest that PCOS belongs to a spectrum of abnormal reactivity of the ovary to human Chorionic Gonadotrophin (hCG) stimulation along with luteoma and luteinic cyst of pregnancy.  Insulin resistance could worsen hyperandrogenism but is not enough to explain virilization. Treatment should focus on protecting the fetus of possible virilization as well as its mother, but also on preserving the subsequent fertility in both.

RESUMO

STUDY QUESTION: Is the negative correlation between the numbers of 2-5 and 6-9 mm follicles influenced by ovarian and/or metabolic parameter(s) in young control women and in patients with polycystic ovarian syndrome (PCOS)? SUMMARY ANSWER: Our study confirmed that the negative correlation between numbers of follicles sized 2-5 and 6-9 mm was stronger in PCOS than in young control women and was not linked to any ovarian or metabolic parameter. WHAT IS KNOWN ALREADY: Previous reports described a direct negative correlation between the number of small antral follicles (2-5 mm) and large antral follicle (6-9 mm) during the early follicular phase (cycle Days 2-5) in normal and PCOS women. Numerous factors, that could be either intrinsic to the ovary or secondary to metabolic influence and/or gonadotropin regulation, might account for this. STUDY DESIGN, SIZE, DURATION: Six hundred and thirty-nine patients with PCOS according to Rotterdam Criteria and 157 control women were recruited in this retrospective cross-sectional study from January 2009 to January 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data were obtained from a database of clinical, hormonal and ultrasound (U/S) features recorded consecutively in a single reproductive medicine centre. Univariate correlations between the various parameters were analysed by the Spearman's correlation test. All variables significantly related to the 2-5 and/or 6-9 mm follicle numbers were included in a principal component analysis (PCA) in order to structure the data and to obtain collections of uncorrelated variables, called principal components (PC), which are linear combinations of the original variables. MAIN RESULTS AND THE ROLE OF CHANCE: By univariate analysis, the 2-5 and 6-9 mm follicle numbers were strongly but negatively correlated in both populations. Many other variables were correlated to the 2-5 and/or 6-9 mm follicle numbers and to each other. By PCA, these relationships were gathered into four independent PCs in each population. In both groups, the 2-5 and 6-9 mm follicle numbers correlated strongly and inversely to a specific PC. Among the other variables tested, only serum oestradiol level correlated weakly to this PC in the control group. Two other uncorrelated PCs gathered relationships between variables linked to the metabolic status and the gonadotropin regulation both in control and PCOS women. Lastly, a fourth PC included relationships which linked to ovarian ageing in controls and to follicle dysregulation in patients with PCOS. LIMITATIONS, REASONS FOR CAUTION: Our controls did not represent the general population since they were recruited in an ART centre; we used a modified Rotterdam classification for PCOS using follicle count and/or serum 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: Factor(s) regulating specifically the equilibrium between the 2-5 and 6-9 mm follicle numbers still need(s) to be identified. More attention should be paid to the oocyte. STUDY FUNDING/COMPETING INTEREST(S): None.

RESUMO

OBJECTIVE: Insulin resistance is known to worsen polycystic ovarian syndrome (PCOS). The management of insulin resistance is crucial in the treatment of PCOS and insulin-sensitizing molecule as myo-inositol (MYO) seems to have promising effects. The aim of our pilot study was to study whether supplementation with MYO can improve patients' sensitivity to clomiphene citrate (CC) in terms of ovulation and pregnancy rates. PATIENTS AND METHODS: This study included 26 patients with PCOS, eligible to ovulation induction with CC. All of them received MYO in combination with CC and folic acid, following the usual protocol. Results concerning ovulation and pregnancy rates were compared to those from our historical cohort of PCOS patients treated with CC alone. RESULTS: Ovulation rate was significantly higher with MYO+CC than with CC alone (65.5% vs. 42%, p=0.0001). The number of patients sensitive to 50 mg/d was 54% with MYO vs. 40% in our reference cohort (NS). The total resistance rate was 19% vs. 27% in the reference cohort (NS). Cumulative pregnancy rate with MYO+CC was 53.8% vs. 42.2% with CC alone (NS). Pregnancy rates per initiated cycle were 16.1% with MYO vs. 12.6% in the historical cohort (NS). DISCUSSION: Although the differences were not significant for most outcomes, probably due to the small number of patients, our pilot study seemed to show a benefit of supplementation with MYO during ovulation induction with CC in PCOS patients. CONCLUSIONS: This study proves the great interest of a RCT and re-opens the possibilities of insulin-sensitizing agents in the treatment of anovulatory patients with PCOS, such as natural products like MYO.

RESUMO

The stimulation of spermatogenesis is the best treatment of infertility for male hypogonadotropic-hypogonadism. The results are very pleasing because a real improvement of semen is sometimes obtained with spontaneous pregnants describing in the literature but after a long duration of treatment, often many months. Sometimes, the treatment improves the technical conditions of ICSI for the embryologists. Stimulation of spermatogenesis by gonadotrophins rFSH and/or hCG is the most used but others treatments, like pulsatile GnRH therapy or clomifene citrate can be used. The purpose of this review is to described the different protocols of stimulation of spermatogenesis and explain their results and finally to see if others indications of stimulation of spermatogenesis are existing.

RESUMO

OBJECTIVES: This work's objective was to define the various non-cancerous inflammatory and infectious mastitis, which may occur outside of pregnancy and lactation, and to identify recommendations for their care based on an exhaustive literature review. MATERIALS AND METHODS: A literature review was conducted by consulting Medline, Cochrane Library, Google scholar and international recommendations in French and English until 31st August 2014. RESULTS AND CONCLUSION: Infectious mastitis (periareolar abscess) is the most common form of non-puerperal abscesses and it is recommended that a suction/drainage needle for abscesses under 5 cm, involving antibiotic therapy (grade C). For abscesses over 5 cm, there is no evidence to recommend a first surgery or suction/drainage. Inflammatory mastitis can be primary or secondary to a systemic disease (diabetes, collagen…; LE4). In case of idiopathic granulomatous mastitis, a steroid therapy or surgery may be indicated, without one or the other of these methods can be recommended. In case of plasma cell mastitis or ductal ectasia, no treatment is recommended.

RESUMO

Breast sonography is required with mammogram to explore clinical breast mass (grade B), colored unipore breast nipple discharge (grade C), or mastitis (grade C). Bi-RADS system is recommended to describe and classify breast-imaging abnormalities. For breast abscess, a percutaneous biopsy is recommended in case of mass or persistent symptoms (grade C). For mastodynia, when breast imaging is normal, no MRI neither breast biopsy is recommended (grade C). Percutaneous biopsy is recommended for BI-RADS 4-5 mass (grade B). For persistent erythematous breast nipple or atypical eczema lesion, a nipple biopsy is recommended (grade C). For distortion and asymmetry, a vacuum core needle biopsy is recommended because of the risk of underestimation by simple core needle biopsy (grade C). For BI-RADS 4-5 microcalcifications without ultrasound signal, a vacuum core needle biopsy of at least 11 gauges is recommended (grade B); in the absence of microcalcifications on radiograph carrots, additional samples are recommended (grade B). For atypical ductal hyperplasia, atypical lobular hyperplasia, lobular carcinoma in situ, flat epithelial with atypia, radial scar, mucocele with atypia, surgical excision is commonly recommended (grade C). Expectant management is feasible after multidisciplinary concertation. For these lesions, when excision is not in sano, no new excision is recommended except for pleomorphic or with necrosis CLIS (grade C). For grade 1 phyllode tumour, in sano surgical resection is recommended; for grade 2 phyllode, 10-mm margins are recommended (grade C). For breast papillary without atypia, complete disappearance of the radiologic signal is recommended (grade C). For breast papillary with atypia, complete surgical excision is recommended (grade C).

RESUMO

The prevalence of obesity is increasing massively over several decades in industrialized countries. Obese women are sexually active but they use fewer contraceptive methods and are at high risk of unintended pregnancy. In addition, obesity is an important risk factor for venous thromboembolism events and arterial thrombosis (myocardial infarction and ischemic stroke). All of these data are to be considered in choosing a contraceptive method for obese women. Except depot medroxyprogesterone acetate injection, the progestin-only contraceptives (progestin only pills and etonogestrel subdermal implant) and the intra-uterine devices are the preferred contraceptive methods in obese women. The combined estrogen-progestin contraceptives (pill, patch and vaginal ring) may be proposed in very strict conditions (no other associated vascular risk factor). Obesity does not increase the risk of failure of most contraceptive methods. Bariatric surgery is a complex situation. It requires to program a possible pregnancy and contraception is needed for several months. Some bariatric surgical techniques such as by-pass can induce gastrointestinal malabsorption. In this situation, all oral contraceptives are not recommended because of a higher risk of failure.

RESUMO

Migraine is a common pathology in women. Migraine disease is well defined by the International Headache Society and has to be distinguished from others types of headaches. The occurrence of migraine attacks is frequently linked to the menstrual cycle. Many studies have related a connexion with hormonal fluctuations and migraine event. Migraine with aura is currently identified as a stroke risk factor and this risk dramatically increases in case of oestroprogestative pill intake and smoking. The World Health Organization established guidelines about oestroprogestative intake in case of migraine while strictly contraindicating oestroprogestative intake in patients with migraine with aura. This review explains the influence of different contraceptive intake, oral contraceptive regimens, and type of oestrogen in oestroprogestative contraceptive on migraine occurrence.

RESUMO

The hypogonadotropic hypogonadism is an easily treatable form of female infertility. The most common cause of hypogonadotropic hypogonadism is functional hypothalamic amenorrhea. The GnRH pump is a simple and effective treatment to restore fertility of patients with hypothalamic amenorrhea: cumulative pregnancy rate is estimated between 70 and 100% after 6 cycles, compared to a low rate of complications and multiple pregnancies. While only 2.8 cycles are on average required to achieve a pregnancy with a pump, this induction of ovulation stays underused in France. The objective of this paper is to propose a practical manual of pulsatile GnRH, in order to improve the accessibility of pulsatile GnRH for patients with hypogonadotropic hypogonadism.

RESUMO

Steroid 21-hydroxylase deficiency is the most common adrenal genetic disease and is also named congenital adrenal hyperplasia. Depending on the severity of CYP21A2 gene mutations, there are severe or "classical" forms and moderate or "nonclassical" forms of 21-hydroxylase deficiency. The enzyme deficiency causes a disruption of adrenal steroidogenesis, which induces hyperandrogenism and elevated plasma levels of progesterone and 17-hydroxyprogesterone, the two substrates of 21-hydroxylase. These endocrine abnormalities will disrupt gonadal axis, endometrial growth and maturation and finally secretion of cervical mucus. All these phenomena contribute to a female hypofertility. Infertility is more severe in classical forms. When to become pregnant, treatment with hydrocortisone or dexamethasone can limit the production of adrenal androgens and progesterone and improves spontaneous pregnancy rates while minimizing the risk of miscarriage, which is usually relatively high in this disease. When planning pregnancy in patients with a 21-hydroxylase deficiency, genotyping the partner is required to screen for heterozygozity (1/50) and to assess the risk of transmission of a classical form in the progeny.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and the leading cause of female infertility. This condition is frequently associated with significant metabolic disorders, including obesity and hyperinsulinemia. Therefore, it seems essential to focus on the pregnancy of these patients and possible obstetric complications. Many studies suggest an increase in the risk of obstetric pathology: early miscarriage, gestational hypertension, preeclampsia, gestational diabetes mellitus diagnosed during early pregnancy, prematurity, low birthweight or macrosomia, neonatal complications and cesarean sections. However, it is difficult to conclude clearly about it, because of the heterogeneity of definition of PCOS in different studies. In addition, many confounding factors inherent in PCOS including obesity are not always taken into account and generate a problem of interpretation. However it seems possible to conclude that PCOS does not increase the risk of placental abruption, HELLP syndrome, liver disease, postpartum hemorrhage, late miscarriage and stillbirth.

RESUMO

CONTEXT: In the general population, about 30% of asymptomatic women have polycystic ovary-like abnormalities (PCO-L), i.e. polycystic ovarian morphology (PCOM) at ultrasound and/or increased anti-Müllerian hormone (AMH) serum level. PCOM has also been reported in 30-50% of women with functional hypothalamic amenorrhea (FHA). OBJECTIVE: The aim of this study was to verify whether both PCOM and excessive AMH level indicate PCO-L in FHA and to elucidate its significance. DESIGN: We conducted a retrospective analysis using a database and comparison with a control population. SETTING: Subjects received ambulatory care in an academic hospital. PATIENTS: Fifty-eight patients with FHA were compared to 217 control women with nonendocrine infertility and body mass index of less than 25 kg/m(2). INTERVENTIONS: There were no interventions. MAIN OUTCOME MEASURES: We measured serum testosterone, androstenedione, FSH, LH, AMH, and ovarian area values. The antral follicle count (AFC) was used as a binary variable (i.e. negative or positive) because of the evolution of its sensitivity over the time of this study. The ability of these variables (except AFC) to detect PCO-L in both populations was tested by cluster analysis. RESULTS: One cluster (cluster 2) suggesting PCO-L was detected in the control population (n = 52; 24%), whereas two such clusters were observed in the FHA population (n = 22 and n = 6; 38 and 10%; clusters 2 and 3, respectively). Cluster 2 in FHA had similar features of PCO-L as cluster 2 in controls, with higher prevalence of positive AFC (70%) and PCOM (70%), higher values of ovarian area and higher serum AMH (P < 0.0001 for all), and testosterone levels (P < 0.01) than in cluster 1. Cluster 3 in FHA was peculiar, with frankly elevated AMH levels. In the whole population (controls + FHA), PCO-L was significantly associated with lower FSH values (P < 0.0001). CONCLUSION: PCO-L in FHA is a frequent and usually incidental finding of unclear significance, as in controls. The association of PCO-L with hypothalamic amenorrhea should not lead to a mistaken diagnosis of PCOS.

RESUMO

OBJECTIVE: It is not known whether polycystic ovaries (PCO) are an ovarian appearance without pathological meaning or whether they share with polycystic ovary syndrome (PCOS) the same ovarian follicle abnormality. There are few studies including strictly selected women with PCO but without other criteria of PCOS. In order to address these issues, we compared hormonal, metabolic and ultrasound parameters obtained from patients with PCO only, patients with PCOS and controls. METHODS: This was a comparative analysis including three age-matched groups of 95 patients, who were included consecutively in a database: controls, patients with sonographic PCO but no symptoms (PCO group) and patients with PCOS. A clinical examination, fasting serum sampling and pelvic ultrasound examination were performed between cycle days 2 and 5 and results were compared between groups. RESULTS: The median serum anti-Mullerian hormone (AMH) level in the PCO group was intermediate between that in controls and that in the PCOS group (33.6 pmol/L, 19.8 pmol/L and 63.3 pmol/L, respectively), the differences being significant after adjustment for follicle number (P < 0.05), while the mean androgen serum level in the PCO group was similar to that in the control group and significantly lower than that in the PCOS group (P < 0.05) (median serum testosterone levels: 0.90 nmol/L, 0.79 nmol/L and 1.39 nmol/L; median androstenedione levels: 5.25 nmol/L, 4.37 nmol/L and 6.09 nmol/L, respectively). Body mass index, waist circumference and insulin levels had no effect on these differences. CONCLUSION: PCO is an abnormal condition, affected women showing no evidence of hyperandrogenism but having higher AMH serum levels compared with controls, suggesting a granulosa cell abnormality in PCO similar to that observed in PCOS. The absence of hyperandrogenism in PCO does not seem linked to the metabolic status.

BACKGROUND: Polycystic ovarian morphology (PCOM) at ultrasound is currently used in the diagnosis of polycystic ovary syndrome (PCOS). We hypothesized that the previously proposed threshold value of 12 as an excessive number of follicles per ovary (FN) is no longer appropriate because of current technological developments. In this study, we have revisited the thresholds for FN and for the serum Anti-Müllerian hormone (AMH) level (a possible surrogate for FN) for the definition of PCOM. METHODS: Clinical, hormonal and ultrasound data were consecutively recorded in 240 patients referred to our department between 2008 and 2010 for exploration of hyperandrogenism (HA), menstrual disorders and/or infertility. RESULTS: According to only their symptoms, patients were grouped as: non-PCOS without HA and with ovulatory cycles (group 1, n = 105), presumption of PCOS with only HA or only oligo-anovulation (group 2, n = 73) and PCOS with HA and oligo-anovulation (group 3, n = 62). By cluster analysis using androgens, LH, FSH, AMH, FN and ovarian volume, group 1 appeared to be constituted of two homogeneous clusters, most likely a non-PCOM non-PCOS subgroup (n = 66) and a PCOM, non-PCOS (i.e. asymptomatic) subgroup (n = 39). Receiver operating characteristic curve analysis was applied to distinguish the non-PCOM non-PCO members of group 1 and to group 3. For FN and serum AMH respectively, the areas under the curve were 0.949 and 0.973 and the best compromise between sensitivity (81 and 92%) and specificity (92 and 97%) was obtained with a threshold values of 19 follicles and 35 pmol/l (5 ng/ml). CONCLUSIONS: For the definition of PCOM, the former threshold of >12 for FN is no longer valid. A serum AMH >35 pmol/l (or >5 ng/ml) appears to be more sensitive and specific than a FN >19 and should be therefore included in the current diagnostic classifications for PCOS.

RESUMO

Anti-Müllerian hormone (AMH) is known to be secreted in women by granulosa cells of growing follicles from the primary to the large antral follicle stage. Serum and intrafollicular AMH levels are elevated in patients with polycystic ovary syndrome (PCOS) due to increased number of small follicles and an increased secretion within each of these small follicles. This excess of AMH is strongly suspected to play a role in the follicular arrest of PCOS by a negative action on aromatase expression and on action of FSH. The interest of serum AMH assay is also clinically important because AMH level is more sensitive, more specific and reproducible from one center to another as the follicle count. Rates above 5ng/ml or 35pmol/l may be considered as a diagnostic criterion for PCOS.

RESUMO

AIMS: This literature review attempts to answer the following questions: 1) When making an assessment of ovarian reserve (OR) in an infertile woman? and 2) what is the investigation that best identifies situations of low OR in order to guide patients towards appropriate care? RESULTS: Some elements of the clinical examination should prompt us to rapidly perform OR tests: patients over 35 years, with cycle disorders or a history of pelvic disease, chemotherapy or radiotherapy. The most widely used OR tests are FSH, estradiol, inhibin B, antral follicle count (AFC), ovarian volume, Antimüllerian hormone (AMH) and dynamic tests. Most studies evaluating these markers were performed within the frame of in vitro fertilization (IVF), and we have little information on their ability to predict spontaneous pregnancy. FSH seems an interesting marker to identify extreme situations of ovarian insufficiency when using a high threshold value. Estradiol assay must always be associated with it. The AFC and AMH both have a good ability to predict the response to ovarian stimulation in IVF. However, their association does not increase their strength of prediction. The ovarian volume, inhibin B as well as dynamic tests are not relevant markers. None of these markers can predict the chances of pregnancy in IVF. CONCLUSION: OR tests must be performed before assisted reproduction techniques (ART) and should include FSH, estradiol, and AMH or CFA. Each center must define its specific standards for the interpretation of results. This assessment will advise the couple about their chances of success in ART and the clinician to adapt its management.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common etiology of menstrual disorders and hyperandrogenism. It is characterized by an excess of ovarian follicles. The mechanisms that underlie folliculogenesis disorder in PCOS appear to arise from primitive ovarian hyperandrogenism. This can be modulated by hormonal factors, such as LH or insulin. Ovarian hyperandrogenism results from a real theca cells dysfunction, whose origin is still poorly understood. It seems that complex genetic factors may be involved, but these have not yet been clearly identified. PCOS also results from granulosa cells dysfunction. For example, intra-ovarian factors, such as anti-mullerian hormone, are possibly involved in ovulation's disorders by blocking the physiological process of follicular recruitment. In turn, the oocyte could also be one of the actors possibly involved in the follicular excess in PCOS.
