RESUMO

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine and metabolic disorder characterized by androgen excess, oligo-anovulatory infertility, polycystic ovaries in ultrasound examination, insulin resistance, and cardiometabolic disorders, with overweight/obesity and visceral adiposity. This review aims to provide an overview of the clinical characteristics and nutritional therapy of PCOS and obesity. The authors analyzed the updated and relevant publications found on PubMed about clinical aspects and nutritional management of PCOS and obesity in studies done in animal and human models. It is crucial an early detection and intervention in PCOS patients to avoid the more challenging control of the onset of more impaired-health conditions that this pathology causes. It is presented evidence that clearly shows the close interaction among oxidative stress, low-grade inflammation, and PCOS. It is also analyzed the relevance of treating metabolic and nutritional correlations of PCOS with a complete therapeutic strategy that includes individualized medication, diet, and healthy habits. By an integral approach and treatment that includes not only medications for PCOS symptoms, supplementation of minerals and vitamins to control PCOS complications but an anti-inflammatory diet, nutritional education, exercise individualized program, lifestyle changes, it is possible to improve insulin resistance, sustained weight loss, ovulation rates, among other goals for the management of this disease. Further studies are needed to clarify mechanisms, beneficial effects, and doses of supplements and precise medication to determine the best combination of diets and exercise programs according to these patients' specific requirements.

RESUMO

Objective: To characterize the serum metabolomic profile and its role in the prediction of poor ovarian response (POR). Patients: Twenty-five women with normal ovarian reserve (24-33 years, antral follicle count [AFC] ≥5, anti-Müllerian hormone [AMH] ≥1.2 ng/ml) as the control group and another twenty-five women with POR (19-35 years, AFC <5, AMH < 1.2 ng/ml) as the study group were collected in our study. The serum levels of the women in both groups were determined from their whole blood by untargeted liquid chromatography-mass spectrometry (LC-MS). Multivariate statistical analysis and cell signal pathways analysis were used to reveal the results. Results: A total of 538 different metabolites were finally identified in the two groups. Tetracosanoic acid, 2-arachidonoylglycerol, lidocaine, cortexolone, prostaglandin H2,1-naphthylamine, 5-hydroxymethyl-2-furancarboxaldehyde, 2,4-dinitrophenol, and D-erythrulose1-phosphate in POR were significantly different from control as were most important metabolites in support vector machines (p <0.05). Metabolomic profiling, together with support vector machines and pathway analysis found that the nicotinate and nicotinamide metabolism pathway, including L-aspartic acid, 6-hydroxynicotinate, maleic acid, and succinic acid semialdehyde, was identified to have significant differences in POR women compared to control women, which may be associated with ovarian reserve. Conclusion: This study indicated that LC-MS-based untargeted metabolomics analysis of serum provided biological markers for women with POR. The nicotinate and nicotinamide metabolism pathway may offer new insight into the complementary prediction and therapeutic potential of POR. The functional associations of these metabolites need further investigation.

RESUMO

BACKGROUND: Diminished ovarian reserve (DOR) is a condition in which the ovary loses its normal reproductive potential, compromising fertility. Although the prevalence and incidence of DOR is increasing, there are currently no effective treatments for this condition. Acupuncture has been reported as an alternative therapy for female infertility. The purpose of this study is to investigate the effect of acupuncture for women with DOR. METHODS/DESIGN: In this randomized controlled trial, a total of 120 women with DOR will be randomly assigned to receive either acupuncture or sham acupuncture for 12 weeks. The primary outcome will be determined by the mean change from baseline in the antral follicle count (AFC) at week 12. Secondary outcomes include serum levels of FSH, LH, E2, and AMH, the length of menstrual cycle, and the score of Self-Rating Anxiety Scale (SAS). DISCUSSION: This study is expected to investigate the effectiveness of acupuncture versus sham acupuncture in improving ovarian reserve for women with DOR.

RESUMO

Under the guidance of the theory of "kidney governing reproduction", this study demonstrated the mechanism of six types of ovulatory infertility caused by kidney deficiency and blood stasis, including anovulatory bleeding, polycystic ovary syndrome, hyperprolactinemia, luteinized unruptured follicle syndrome, luteal phase deficiency, and primary ovarian insufficiency. A series of studies have confirmed that integrated Chinese and western medicine can increase the responsiveness of the ovaries to gonadotropins and improve ovarian function by regulating the effects of estradiol(E_2), prolactin(PRL), and reducing follicle-stimulating hormone(FSH), luteinizing hormone(LH), progestin(P), and testosterone(T). It can also improve ovulation rate and pregnancy success rate by promoting follicle development, discharging, and synchronizing endometrial growth. This study illustrated the diagnosis and treatment of ovulatory infertility caused by kidney deficiency and blood stasis with integrated traditional Chinese and Western medicine in the "disease-syndrome-symptom" research mode, and highlighted the traditional Chinese medicine(TCM) idea of differentiating diseases based on syndromes and unique advantages of the combination of disease differentiation and syndrome differentiation, and interpreted TCM principle of "treating different diseases with the same method".

RESUMO

BACKGROUND: Thin endometrium negatively impacts the reproductive function. Current treatments for thin endometrium do not always improve endometrial receptivity. Preliminary evidence suggests that electroacupuncture could have potential therapy for thin endometrium in infertile women. Thus, this randomized controlled trial was designed to test whether electroacupuncture can improve endometrial receptivity in infertile women with thin endometrium. METHODS: This study is a randomized, single-blinded, controlled, clinical trial. A total of 142 eligible patients will be recruited and randomly assigned to the electroacupuncture (EA) group or the sham electroacupuncture (SEA) group in a 1:1 ratio. Participants will receive 36 sessions over three menstrual cycles (12 weeks in total), with the same acupoint prescription. The primary outcome of this trial is endometrial thickness in the midluteal phase. The secondary outcomes include endometrial pattern, resistance index (RI) and pulsatility index (PI) of bilateral uterine artery and endometrium blood flow, serum estradiol (E2) and progesterone (P), and pregnancy rate. The pregnancy rate will be evaluated during a 6-month follow-up after completion of the trial. All other outcomes will be evaluated before treatment, during the treatment of 1st, 2nd, and 3rd menstrual cycle, and 6 months after treatment. DISCUSSION: If the outcome confirms the effectiveness of electroacupuncture for thin endometrium in infertile women, this treatment will be proposed for application in clinical practice.

RESUMO

BACKGROUND: Mediated via the androgen receptor on granulosa cells, models of small growing follicle stages demonstrate dependence on testosterone. Androgen deficiency reduces ovarian response to follicle stimulation hormone (FSH), granulosa cell mass and estradiol (E2) production falls and FSH, therefore, rises. Though potentially of adrenal and/or ovarian origin, androgen deficiency in association with female infertility is almost universally primarily of adrenal origin, raising the possibility that women with presumptive diagnosis of primary ovarian insufficiency (POI), also called primary ovarian failure (POF) may actually suffer from secondary ovarian insufficiency (SOI) due to adrenal hypoandrogenism that leads to follicular arrest at small-growing follicle stages. METHODS: This retrospective cohort study was performed in a private, academically affiliated infertility center in New York City. We searched the center's anonymized electronic research data bank for consecutive patients who presented with a diagnosis of POI, defined by age <41 year, FSH > 40.0 mIU/mL, amenorrhea for at least 6 month, and low testosterone (T), defined as total T (TT) in the lowest age-specific quartile of normal range. This study did not include patients with oophoritis. Since dehydroepiandrosterone sulfate (DHEAS) is the only androgen almost exclusively produce by adrenals, adrenal hypoandrogenism was defined by DHEAS < 100ug/dL. Thirteen of 78 presumed POI women (16.67%) qualified and represented the original study population. POI patients are usually treated with third-party egg donation; 6/13, however, rejected egg donation for personal or religious reasons and insisted on undergoing at least one last IVF cycle attempt (final study population). In preparation, they were supplemented with DHEA 25 mg TID and CoQ10 333 mg TID for at least 6 weeks prior to ovarian stimulation for IVF with FSH and human menopausal gonadotropins (hMG). Since POI patients are expected to be resistant to ovarian stimulation, primary outcome for the study was ovarian response, while secondary outcome was pregnancy/delivery. RESULTS: Though POI/POF patients usually are completely unresponsive to ovarian stimulation, to our surprise, 5/6 (83.3%) patients demonstrated an objective follicle response. In addition, 2/6 (33.3%) conceived spontaneously between IVF cycles, while on DHEA and CoQ10 supplementation and delivered healthy offspring. One of those is currently in treatment for a second child. CONCLUSIONS: This preliminary report suggests that a surprising portion of young women below age 41, tagged with a diagnosis of POI/POF, due to adrenal hypoandrogenism actually suffer from a form of SOI, at least in some cases amenable to treatment by androgen supplementation. Since true POI/POF usually requires third-party egg donation, correct differentiation between POI and SOI in such women appears of great importance and may warrant a trial stimulation after androgen pre-supplementation for at least 6 weeks.

RESUMO

To assess whether oral supplementation of vitamin D3, myo-inositol, folic acid and melatonin affects IVF outcomes. One hundred and twenty consecutive infertile women attending IVF treatment were 1:1 randomly distributed in two groups. Women in group A (control) were assigned to receive myo-inositol, alpha-lactalbumin and folic acid in the morning, and myo-inositol, folic acid and melatonin in the evening. Women in group B (treated) were assigned to receive analogous treatment, with the addition of cholecalciferol (vitamin D3) in the evening from the early beginning of the luteal phase. 50 patients in group A and 50 in group B underwent blastocyst transfer and were considered in the statistical analysis. Vitamin D3 levels significantly increased after 45 days of treatment: 33.2 ng/ml in group B Vs. 24.3 ng/ml in group A (p < .0001). The implantation rate increased as well: 37.1% in group B Vs. 19.2% in group A (p < .0151). Overall, the results indicate that increased vitamin D3 levels positively correlate with the implantation rate in IVF. Because of the low number of participants, these findings need to be confirmed with larger cohorts of patients.

RESUMO

OBJECTIVE: To study the association between extra vitamin D from a mandatory margarine fortification program and chance of live birth among infertile women. DESIGN: Nationwide cohort study. SETTING: Not applicable. PATIENT(S): The study population consisted of 16,212 women diagnosed with infertility from June 1, 1980, to August 31, 1991. INTERVENTIONS(S): We took advantage of the mandatory vitamin D fortification program of margarine in Denmark that was abruptly stopped on May 31, 1985. The termination of the vitamin D fortification served as a cutoff point to separate the study population into various exposure groups. MAIN OUTCOME MEASURE(S): Odds ratios and 95% confidence intervals for the association between vitamin D exposure status and chance of a live birth within 12, 15, and 18 months after first infertility diagnosis. RESULT(S): Women who were diagnosed with infertility during the vitamin D-exposed period had an increased chance of a live birth compared with women diagnosed with infertility during the nonexposed period. For women diagnosed with infertility during the wash-out period, the chance of a live birth was also increased, but somewhat lower. Similar estimates were obtained with longer follow-up, in women with anovulatory infertility, and little seasonal variation was observed when calendar period of conception was applied. CONCLUSION(S): Our findings suggest that infertile women exposed to extra vitamin D from a margarine fortification program had an increased chance of live birth compared with women not exposed to extra vitamin D from fortification.

RESUMO

This study was performed to determine the effects of selenium supplementation on clinical symptoms and gene expression related to inflammatory markers in infertile women with polycystic ovary syndrome (PCOS) who were candidate for in vitro fertilization (IVF). Thirty-six women candidate for IVF were recruited in this randomized double-blinded, placebo-controlled trial. They (n = 18/group) were randomly assigned into intervention groups to take either 200 µg/day of selenium or placebo for 8 weeks. RT-PCR findings indicated that selenium supplementation downregulated gene expression of interleukin-1 (IL-1) (P < 0.004) and tumor necrosis factor alpha (TNF-α) (P = 0.02) in lymphocytes of patients with PCOS compared with the placebo. In addition, selenium supplementation upregulated gene expression of vascular endothelial growth factor (VEGF) (P = 0.001) in lymphocytes of patients with PCOS compared with the placebo. Selenium supplementation had no significant effect on clinical symptoms and gene expression of IL-8 (P = 0.10) and transforming growth factor beta (TGF-ß) (P = 0.63). Overall, our findings documented that selenium supplementation for 8 weeks to infertile women candidate for IVF improved IL-1, TNF-α, and VEGF gene expression, though selenium had no effect on clinical symptoms and, IL-8 and TGF-ß gene expression.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) affects between 8 and 18% of women and is the leading cause of female anovulatory infertility. Unfortunately, common treatments for women trying to conceive can be ineffective as well as disruptive or harmful to patients' quality of life. Despite evidence that women with PCOS have expressed the need for alternative fertility treatments, lifestyle interventions incorporating a nutritional plan with supplementation, increased physical activity, and techniques for stress management have not been combined as a program and studied in this population. Literature suggests that each of these individual components can positively influence reproductive hormones and metabolic health. METHODS/DESIGN: This is a randomized controlled trial which will include 240 women diagnosed with PCOS, according to the Rotterdam criteria, who are trying to conceive. Participants will be randomized to either a comprehensive lifestyle intervention program or prescribed an oral fertility medication, letrozole. These two groups will be further randomized to consume either myo-inositol or a placebo. Participants will be between the ages of 18 and 37 years. Exclusion criteria include women who have already begun fertility treatment, who are currently using myo-inositol or have taken it within the past 3 months, or who are being treated for, or have a history of, an eating disorder. The primary outcome will be the ovulation rate, the secondary outcome will be conception. Other outcomes include miscarriage rates, validated rating measures of overall quality of life (including social, relational, mind/body and emotional sub-categories) and mental health scores (depression, anxiety, and stress). DISCUSSION: This trial will determine the effectiveness of a structured lifestyle-based comprehensive intervention program for women with PCOS experiencing infertility. In addition, it will determine whether supplementing with myo-inositol provides any further benefit. The objective of this study is to assess a possible non-pharmacological solution to ovulatory dysfunction in these patients and perhaps improve other associated features of PCOS.

RESUMO

Vitamin D (VD) deficiency is associated with reproductive failure. However, the relationship between VD and maternal immunity remains unclear. We investigated the clinical efficacy of VD in maternal T-helper (Th) cytokines in 276 infertile women and examined for Th1 and Th2 cells based on the deficient, insufficient, and sufficient serum 25-hydroxyvitamin D3 (25[OH]VD) levels (<12, 12⁻30, and >30 ng/mL, respectively). Most infertile women had a low-level of VD (87.3%). Immunological tests of pre-/post-VD supplementation were performed in patients who were deficient and insufficient in VD. Of 23 patients, 11 (47.8%) exhibited sufficient VD levels after supplementation. Th1/Th2 cell ratio in patients with insufficient VD was significantly decreased after supplementation (p = 0.004). After supplementation, serum 25(OH)VD levels of the patients: 11 in the sufficient group showed significant decreases in Th1 cell level and Th1/Th2 cell ratio (p = 0.032 and 0.010, respectively), whereas no significant differences in Th1/Th2 cell ratio were recognized in the insufficient group. Furthermore, mid-luteal endometrial biopsies (n = 18) were processed for primary cultures and measured interferon [IFN]-γ and interleukin [IL]-4 in condition media. Decidualizing cultures with 1,25-dihydroxvitamin D3 (1,25[OH]2VD) decreased IFN-γ. Sufficient VD supplementation in women with insufficient VD may optimize maternal T-helper cytokines during pregnancy via rebalancing the Th1/Th2 cell ratio.

RESUMO

BACKGROUND: This study aimed to detect changes in hormone levels in the hypothalamic-pituitary-ovarian axis in Sprague-Dawley (SD) rats with hypothyroidism, and identify differences in the pregnancy and abortion rates of female adult rats. The potential role of gonadotropin releasing hormone (GnRH) as the link between the hypothalamic-pituitary-ovarian axis and reproductive function regulated by thyroid hormones was also investigated. METHODS: Female SD rats (n = 136) were causally classified into two groups: the normal-drinking-water group (n = 60) and the 0.05% propylthiouracil-drinking-water group (PTU 2 mg/kg/day, n = 76) to establish an adult rat model of hypothyroidism (6 weeks). Female and male rats at a ratio of 1:2 were used to establish a hypothyroidism pregnancy model. GnRH mRNA and GnRH receptor (GnRHR) expression in rats was detected using real time quantitative PCR(qRT-PCR) and immunohistochemistry, respectively. RESULTS: The abortion rate differed significantly between the hypothyroidism pregnancy group and the normal pregnancy group (P < 0.05). No significant differences were found in the distribution of the GnRHR among the five nuclei (hypothalamic arcuate nucleus, hypothalamic ventromedial nucleus, hypothalamic anterior nucleus, paraventricular nucleus of the hypothalamus, and ventral premammillary nucleus) of the hypothalamus and ovary (P > 0.05). Hypothyroidism had no significant effect on GnRH mRNA expression in the hypothalamic-pituitary-ovarian axis in the four groups (normal control group, normal pregnancy group, hypothyroidism pregnancy group, and hypothyroidism group) (P > 0.05). CONCLUSIONS: Hypothyroidism had an adverse impact on pregnancy in rats and may affect the distribution of pituitary GnRHR, whereas it did not obviously affect the distribution of GnRHR in the nuclei of the hypothalamus and ovary. Hypothyroidism had no effect on GnRH mRNA expression.

RESUMO

OBJECTIVE: To systematically review and appraise the existing evidence in relation to the efficacy and safety of pulsatile gonadotropin-releasing hormone (pGnRH) for the treatment of women with hypothalamic amenorrhea (HA). DESIGN: Systematic review and meta-analysis. SETTING: Not applicable. PATIENT(S): A total of 35 studies (three randomized and 32 observational) encompassing 1,002 women with HA. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Primary outcomes: ovulation rate (OvR), pregnancy per ovulatory cycle rate (POR), and live birth per ovulatory cycle rate (LBOR). SECONDARY OUTCOMES: multiple gestation (MG), ovarian hyperstimulation syndrome (OHSS), and superficial thrombophlebitis (ST) rates. The summary measures were expressed as proportions and 95% confidence intervals (CI). RESULT(S): Pulsatile GnRH treatment appears to achieve high OvRs. A trend toward high PORs and LBORs among women with HA is demonstrated. SC pGnRH achieves comparable OvR compared with IV pGnRH. The incidence of OHSS is low and of mild severity. Treatment with pGnRH is associated with low but slightly higher MG rates compared with the general population. IV administered pGnRH is rarely associated with ST. CONCLUSION(S): The high OvRs leading to a high rate of singleton pregnancies and the low likelihood of OHSS render the pGnRH treatment modality both effective and safe for the treatment of women with HA of either primary or secondary origin.

RESUMO

PROBLEM: The purpose of this study was to explore whether vitamin D might be a marker of female primary infertility in association with the presence of autoimmune diseases (ADs). METHODS: The study was a cross-sectional descriptive study in consecutive outpatients of the Polymedical Center for Prevention of Recurrent Spontaneous Abortion (RSA), in Rome, Italy. Women were eligible if they received a diagnosis of primary infertility or RSA. Serum vitamin D, calcium, and PTH were analyzed. RESULTS: Women with primary infertility (n=70) or RSA/non-infertile (n=105) were enrolled; controls (n=250) were included. Infertile women presented lower vitamin D (P=0.03) and higher prevalence of AD (P=0.007) than non-infertile women. In the multivariate analysis, the presence of ADs is associated with higher odds of infertility (OR=2.2), while normal vitamin D was a protective factor (OR=0.9). CONCLUSION: We described that having vitamin D deficiency and suffering from an AD are independent risk factors for women primary infertility. Supplementation of vitamin D might be useful for pregnancy outcome.

RESUMO

Improvements in surgery have resulted in more women with repaired congenital heart disease (CHD) surviving to adulthood. Women with CHD, who wish to embark on pregnancy require prepregnancy counselling. This consultation should cover several issues such as the long-term prognosis of the mother, fertility and miscarriage rates, recurrence risk of CHD in the baby, drug therapy during pregnancy, estimated maternal risk and outcome, expected fetal outcomes and plans for pregnancy. Prenatal genetic testing is available for those patients with an identified genetic defect using pregestational diagnosis or prenatal diagnosis chorionic villus sampling or amniocentesis. Centralisation of care is needed for high-risk patients. Finally, currently there are no recommendations addressing the issue of the delivery. It is crucial that a dedicated plan for delivery should be available for all cardiac patients. The maternal mortality in low-income to middle-income countries is 14 times higher than in high-income countries and needs additional aspects and dedicated care.

RESUMO

BACKGROUND: The status characterized by the imbalance between pro-oxidants and antioxidants molecules, defined as oxidative stress, has been suggested to be involved in the pathogenesis of subfertility in females. This study aims to evaluate the impact of a complete micronutrients supplementation on oxidative stress levels in follicular microenvironment as well as on in vitro fertilization (IVF) outcome. METHODS: This preliminary study was conducted between January 2014 and July 2015 at the Siena University Hospital Infertility Clinic. Serum and follicular fluid were collected from infertile women aged > 39 years who underwent two in vitro fertilization cycles: in the first cycle they were treated with GnRH-antagonist protocol and gonadotropins for controlled ovarian hyperstimulation, whereas in the second cycle ovarian stimulation protocol was associated to micronutrients supplementation, starting three months earlier. Protein oxidation levels and total antioxidant capacity in serum and in follicular fluid were evaluated in IVF cycles with or without micronutrients supplementation. Differences in IVF outcome parameters were statistically evaluated. RESULTS: Two-dimensional electrophoresis analyses demonstrated that when patients assumed micronutrients before IVF cycles, follicular fluid and serum proteins were protected from oxidative damage. Comparable results were obtained when total antioxidant capacity was measured. Moreover, the mean number of good quality oocytes retrieved when patients received micronutrients supplementation was significantly increased. CONCLUSION: The additional treatment with micronutrients, starting three months before IVF cycles, protects the follicular microenvironment from oxidative stress, thus increasing the number of good quality oocytes recovered at the pick up.

RESUMO

The aim of the study was to investigate whether women affected by unexplained infertility may have undiagnosed dietary imbalances which negatively affect fertility. Secondarily, we investigated whether varying degrees of nutritional abnormalities may benefit from different periconceptional dietary supplementations, evaluating the most effective intervention in improving pregnancy rate after in vitro fertilization (IVF). We conducted a survey on 2 cohorts of patients (group A: unexplained infertility and group B: healthy first trimester spontaneous pregnancies) with the scope of investigating and comparing their dietary status discriminating women without dietary abnormalities (cohort 1) from those with abnormalities exclusively in micronutrient intake (cohort 2) or combined abnormalities in both micronutrient and macronutrient intake and associated obesity (cohort 3). All women included in group A were offered the opportunity to receive a prescription for one of the 3 designated daily dietary supplementation schemes (subgroups A1, A2, and A3) which were to be implemented in the 3 months immediately prior to beginning IVF treatment. When compared with fertile women, patients having unexplained infertility showed significant abnormalities in dietary habits. These differences ranged from a minimal imbalance in micronutrient intake (potentially avoidable with dietary supplementation) to severe combined macronutrient and micronutrient imbalance frequently associated with obesity (partially amendable by inositol supplementation and frequently requiring long-term dietary reeducation before establishment of fertility). Nutritional investigation and treatment may explain and resolve a portion of cases of unexplained infertility, improving the outcome of IVF treatment and, with minimal imbalances, likely restore spontaneous fertility.

RESUMO

This study presents results of 113 infertile couples treated with supplements speroton and pregnoton containing folic acid, L-carnitine, vitamin E, zinc, and other vitamins and minerals. Infertility in couples was due to both the pathology of spermatogenesis, and female genital diseases. It has been demonstrated that intake of Speroton restores impaired motility in the ejaculate of patients with several forms of pathospermia, and Pregnoton ensure its preservation in vaginal secretions.

RESUMO

OBJECTIVE: To evaluate revised criteria for polycystic ovarian morphology (PCOM) in the diagnosis of polycystic ovary syndrome (PCOS) in anovulatory infertility. DESIGN: Prospective cohort study. PATIENTS: WHO Group II anovulatory infertile women (n = 75). MEASUREMENTS: Clinical, sonographic and endocrine parameters, including anti-Müllerian hormone (AMH). RESULTS: The Rotterdam criteria for PCOM (antral follicle count (AFC) ≥12 and/or ovarian volume >10 ml) were fulfilled in 93% of the women. The PCOM prevalence was 68% when increasing the threshold to AFC >20 and 76% according to an AMH-based threshold of >35 pmol/l. The most recently proposed AFC ≥ 25 threshold reduced the PCOM prevalence to 52% (n = 39), leaving 48% (n = 36) without features of PCOM. Comparing the 36 women with non-PCOM with the 39 women in the PCOM group according to AFC ≥ 25, 22% vs 59% (P = 0·001) had serum LH >10 IU/l, 11% vs 41% (P = 0·003) had an LH/FSH ratio >2 and 19% vs 41% (P = 0·04) had hirsutism and/or elevated total testosterone, free testosterone, and/or androstenedione. The non-PCOM group included significantly more women with secondary infertility. The median AMH in the non-PCOM group was 47 pmol/l, which was twofold lower than in the PCOM group but above the upper limit of normo-ovulatory women. CONCLUSIONS: According to a revised threshold of 25 follicles, almost half the anovulatory infertile women do not have PCOM. The characteristics of these women may be compatible with hypothalamic anovulation, but according to AMH levels, the ovaries remain multifollicular. PERSPECTIVES: A better distinction between hypothalamic amenorrhoea and PCOS could improve treatment strategies for anovulatory infertility.
