Insulin resistance is an important “upstream” driver for reproductive and metabolic abnormalities in women with Polycystic Ovary Syndrome (PCOS). This theoretical background is now supported by substantial evidence for treating women with PCOS with insulin sensitising agents such as metformin or the thiazolidinediones…

Anti-Müllerian hormone (AMH) is a homodimeric glycoprotein, a member of the transforming growth factor-β superfamily. Over the last decade, a large number of studies examining the multiple roles of AMH have been published. AMH levels accurately reflect the ovarian follicular reserve and could, therefore …

Postprandial dysmetabolism is a postprandial state characterized by abnormal metabolism of glucose and lipids and, more specifically, of elevated levels of glucose and triglyceride (TG) containing lipoproteins. Since there is evidence that postprandial dysmetabolism is associated with increased cardiovascular mortality and morbidity, due to macro- and microvascular complications …

Polycystic ovary syndrome (PCOS) is a complex and heterogeneous disorder characterized by hyperandrogenemia, hyperinsulinemia, insulin resistance, and chronic anovulation. It is the most common endocrine disorder in women of reproductive age with an enigmatic pathophysiologic and molecular basis. The high prevalence of affected …

Insulin resistance is a key pathogenic defect of the clustered metabolic disturbances seen in polycystic ovary syndrome (PCOS). Metformin is an insulin sensitizer acting in the liver and the peripheral tissues that ameliorates the metabolic and reproductive defects in PCOS …

Polycystic Ovary Syndrome is a heterogenous syndrome of unknown causation commonly associated with obesity. Τhe particular timing of the onset of obesity may be important, since the earlier the onset of obesity the greater the severity of the metabolic and hormonal aberrations …

OBJECTIVE: Τo evaluate the impact of elevated serum Δ4A levels on the hormonal and metabolic features of the different phenotypes of PCOS. DESIGN: 1276 women with PCOS according to the Rotterdam criteria were included …

OBJECTIVE: The long-acting glucagon-like peptide 1 receptor agonist liraglutide is linked to progressive and sustained weight loss in obese people with diabetes. However, its efficacy and safety in women with polycystic ovary syndrome (PCOS) has not yet been addressed …

OBJECTIVE: The aim of this study was to evaluate the influence of polycystic ovary syndrome (PCOS) and obesity on circulating markers of low-grade inflammation—tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6) and high sensitive C-reactive protein (hsCRP)—in young women without major cardiovascular (CV) risk factors …

OBJECTIVE: During the last decade cardiovascular risk factors and endothelial dysfunction have been shown to be present early in life in women with Polycystic Ovary Syndrome (PCOS). The aim of the present study was a global assessment of abnormalities in the arterial bed of young women with PCOS by non-invasive, reproducible methods…

OBJECTIVE: Advanced glycation end products (AGEs) activate the intracellular Nuclear Factor-κB pathway in endothelial cells, leading to production of endothelin-1 (ET-1), a peptide which causes endothelial dysfunction. The aim of the present study was to assess ΕΤ-1 and AGEs levels in women with polycystic ovary syndrome …

The role of vitamin D in female reproduction has been intensively examined over the last few decades. A large body of evidence suggests that vitamin D might have beneficial effects on metabolic/hormonal parameters of PCOS and endometriosis, while it appears to be associated with IVF outcomes. However, due to the heterogeneity among observational and interventional studies, no cause-effect relationship has yet been established. The aim of this review is to analyze recent in vitro animal and human studies …

OBJECTIVE: Congenital adrenal hyperplasia (CAH) is an endocrine autosomal recessive disorder with various symptoms of diverse severity. Mild hyperandrogenemia is the most commonclinical feature in non-classic CAH patients and 95% of the cases are identified by mutations in the CYP21A2 gene. In the present study, the second most common cause for non-classic CAH (NC-CAH), 11β-hydroxylase deficiency due to mutations in the CYP11B1 gene, is investigated …
