BACKGROUND: Several studies have reported higher levels of Alanine aminotransferase (ALT) in women with polycystic ovary syndrome (PCOS) compared with control subjects. Plasma ALT levels are considered a marker of hepatic lipotoxicity because of their significant associations with different hepatic metabolic dysfunctions, such as hepatic steatosis and hepatic insulin resistance. METHODS: Retrospective chart review aiming to assess, in PCOS women, the relationship between ALT levels and measures of lipotoxicity consequences that are available clinically, both during fasting and using the oral glucose tolerance test...

STUDY QUESTION: Is the presence of polycystic ovary syndrome (PCOS) associated with anogenital distance (AGD), a biomarker for the prenatal hormonal environment? SUMMARY ANSWER: The presence of PCOS is associated with longer AGD. WHAT IS KNOWN ALREADY: Although the aetiology of PCOS is unclear, emerging data suggest that the natural history of PCOS may originate from intrauterine life. Prenatal exposure to androgen hormones is considered an important factor of PCOS...

BACKGROUND: Insulin resistance and hyperinsulinemia may play a role in pathogenesis of PCOS. One of the common therapeutic methods is using insulin-sensitizing drugs such as metformin and thiazolidinediones. OBJECTIVE: The purpose was to determine the effect of metformin and pioglitazone on clinical, hormonal and metabolic parameters in women with PCOS. MATERIALS AND METHODS: Eighty four women randomly received one of the following for 3 months: metformin (n=28) (500 mg three times a day), pioglitazone (30 mg daily) (n=28) and combination of both metformin and pioglitazone (n=28) (30 mg/day pioglitazone plus 500 mg metformin three times a day)...

Adipokines, including adiponectin and resistin, are cytokines produced mainly by adipose tissue. They play a significant role in the metabolic functions that regulate insulin sensitivity and inflammation. Alteration of adiponectin and resistin plasma levels, or their expression in metabolic and gonadal tissue, are observed in some metabolic pathologies, such as obesity. Several studies have shown that these two hormones and the receptors for adiponectin, AdipoR1 and AdipoR2, are present in various reproductive tissues in both sexes of different species...

Androgens are essential for the normal function of mature antral follicles but also have a role in the early stages of follicle development. Polycystic ovary syndrome (PCOS), the commonest cause of anovulatory infertility, is characterized by androgen excess and aberrant follicle development that includes accelerated early follicle growth. We have examined the effects of testosterone and dihydrotestosterone (DHT) on development of isolated mouse preantral follicles in culture with the specific aims of investigating interaction with FSH, the steroidogenic pathway and with growth factors of the TGFβ superfamily that are known to have a role in early follicle development...

It has been shown that serum homocycteine (Hcy) levels are higher in women with polycystic ovary syndrome (PCOS). However, the specific role of hyperhomocycteinemia (HHcy) in the development of PCOS has never been reported. Adipose tissue inflammation is featured by the infiltration of macrophages that plays a critical role in the pathogenesis of glucose and insulin intolerance. In this study, C57BL/6 mice were treated with dehydroepiandrosterone (DHEA) and/or high methionine diet to induce PCOS and HHcy mice models...

The ovarian follicle is a major site of steroidogenesis, crucially required for normal ovarian function and female reproduction. Our understanding of androgen synthesis and metabolism in the developing follicle has been limited by sensitivity and specificity issues of previously used assays. Here we used liquid chromatography-tandem mass spectrometry to map the stage-dependent endogenous steroid metabolome in an encapsulated in vitro follicle growth system, from murine secondary through antral follicles. Furthermore, follicles were cultured in the presence of androgen precursors, non-aromatizable active androgen and androgen receptor (AR) antagonist to assess effects on steroidogenesis and follicle development...

Resveratrol, a natural compound found in grapes, became very popular for its suggested protective effects against aging. It was reported to have similar positive effects on the human metabolism as caloric restriction. Recently, positive effects of resveratrol on steroid biosynthesis in cell systems and in humans suffering from polycystic ovary syndrome have also been reported, but the exact mechanism of this action remains unknown. Sirtuins seem targeted by resveratrol to mediate its action on energy homeostasis...

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder characterized by reproductive, endocrine, and metabolic abnormalities. As the origins of PCOS remain unknown, mechanism-based treatments are not feasible and current management relies on treatment of symptoms. Hyperandrogenism is the most consistent PCOS characteristic; however, it is unclear whether androgen excess, which is treatable, is a cause or a consequence of PCOS. As androgens mediate their actions via the androgen receptor (AR), we combined a mouse model of dihydrotestosterone (DHT)-induced PCOS with global and cell-specific AR-resistant (ARKO) mice to investigate the locus of androgen actions that mediate the development of the PCOS phenotype...
