Our data confirm that the prevalence of SCH is increased in PCOS women. The presence of SCH is associated with endocrine and metabolic imbalances of PCOS, and the excessive body weight seems to promote this interplay.

The objective of the study was to investigate the effects of 6 months of melatonin administration on clinical, endocrine, and metabolic features of women affected by polycystic ovary syndrome (PCOS). This is a prospective cohort study including 40 normal-weight women with PCOS between January and September 2016, enrolled in an academic research environment. Ultrasonographic pelvic examinations, hirsutism score evaluation, hormonal profile assays, oral glucose tolerance test, and lipid profile at baseline and after 6 months of melatonin administration were performed. Melatonin treatment significantly decreased androgens levels (free androgen index: P < .05; testosterone: P < .01; 17 hydroxyprogesterone: P < .01). Follicle-stimulating hormone levels significantly raised (P < .01), and anti-Mullerian hormone serum levels significantly dropped after 6 months of melatonin treatment (P < .01). No significant changes occurred in glucoinsulinemic and lipid parameters after treatment except a significant decrease of low-density lipoprotein cholesterol. Almost 95% of participants experienced an amelioration of menstrual cycles. Until now, only few data have been published about the role of melatonin in women with PCOS. This is the first study focused on the effects of exogenous oral melatonin administration on the clinical, endocrine, and metabolic characteristics of patients with PCOS. After 6 months of treatment, melatonin seems to improve menstrual irregularities and biochemical hyperandrogenism in women with PCOS through a direct, insulin-independent effect on the ovary. Based on our results, melatonin could be considered a potential future therapeutic agent for women affected by PCOS.

Both treatments improved the glyco-insulinaemic features of obese PCOS patients, but only metformin seems to exert a beneficial effect on the endocrine and clinical features of the syndrome.

The aim of our study was to investigate the effects of a combined treatment with alpha-lipoic acid (ALA) and myoinositol (MYO) on clinical, endocrine and metabolic features of women affected by polycystic ovary syndrome (PCOS). In this pilot cohort study, forty women with PCOS were enrolled and clinical, hormonal and metabolic parameters were evaluated before and after a six-months combined treatment with ALA and MYO daily. Studied patients experienced a significant increase in the number of cycles in six months (p < 0.01). The free androgen index (FAI), the mean androstenedione and DHEAS levels significantly decreased after treatment (p < 0.05). Mean SHBG levels significantly raised (p < 0.01). A significant improvement in mean Ferriman-Gallwey (F-G) score (p < 0.01) and a significant reduction of BMI (p < 0.01) were also observed. A significant reduction of AMH levels, ovarian volume and total antral follicular count were observed in our studied women (p< 0.05). No significant changes occurred in gluco-insulinaemic and lipid parameters after treatment. The combined treatment of ALA and MYO is able to restore the menstrual pattern and to improve the hormonal milieu of PCOS women, even in the absence of apparent changes in insulin metabolism.

Rotterdam criteria identified 4 polycystic ovary syndrome (PCOS) phenotypes based on the combination of anovulation (ANOV), hyperandrogenism (HA), and polycystic ovaries (PCOs): phenotype 1 (ANOV + HA + PCO), phenotype 2 (ANOV + HA), phenotype 3 (HA + PCO), and phenotype 4 (ANOV + PCO). Anti-Müllerian hormone (AMH) was suggested to play a pathophysiologic and diagnostic role in this syndrome. The aim of this study was to compare AMH levels among the different phenotypes in relation to clinical, endocrine, and metabolic features. We enrolled 117 women with PCOS (body mass index: 25.89 ± 6.20 kg/m(2), age range: 18-37 years) and 24 controls. Anthropometric characteristics, hirsutism score, ultrasound ovarian features, and hormonal parameters, including AMH, were evaluated. Each participant also underwent an oral glucose tolerance test and an euglycemic-hyperinsulinemic clamp. The prevalence of phenotypes 1 to 4 was 62.4%, 8.6%, 11.1%, and 17.9%, respectively. Body mass index and insulin resistance indexes were similar among the groups. Phenotype 1 showed the highest luteinizing hormone, androgens levels, ovarian volume, and AMH concentrations (9.27 ± 8.17 ng/mL,P< .05) versus phenotype 2 and controls. Phenotype 2 women were hirsute, showed an intermediate free androgen index value, low ovarian volume, and low AMH levels (4.05 ± 4.12 ng/mL). Phenotype 3 showed an intermediate state of HA and slightly augmented AMH levels (5.87 ± 4.35 ng/mL). The clinical and endocrine characteristics of phenotype 4 resembled those of controls, except for higher ovarian volume and AMH levels (7.62 ± 3.85 ng/mL;P< .05). Our results highlight the heterogeneity of the association between increased AMH levels, menstrual dysfunction, and HA in the different PCOS phenotypes, thus offering a key to an understanding of the current controversy on the value of AMH measurement in PCOS.

Combined laparoscopy and hysteroscopy in women with unexplained infertility may reveal previously undiagnosed pathologies that could require ART, and in those without abnormal surgical finding, ART does not improve pregnancy rate.

Thanks to the recent advances in reproductive medicine, more and more young women with breast cancer may be offered the possibility of preserving their fertility. Fertility can be endangered by chemotherapy, by treatment duration and by patient’s age at diagnosis. The currently available means to preserve a young woman’s fertility are pharmacological protection with gonadotrophin-releasing hormone analogues during chemotherapy, and ovarian tissue or oocyte/embryo freezing before treatment. New future venues, including in vitro maturation, will improve the feasibility and efficacy of the fertility preservation methods in breast cancer patients.
