Polycystic ovary syndrome (PCOS) is a complex disease. Depending on the used criteria the prevalence of PCOS ranges from 6 to 20%. It is necessary to exclude diseases leading to androgen excess. The participation of genetic and environmental factors is considered in the etiology of PCOS development. The highest rate of incidence of PCOS is assessed in girls who were born SGA and developed premature adrenarche later in life.The free androgen index (FAI) is concerned as the most sensitive marker of hyperandrogenaemia in PCOS although insulin resistance, anti-Müllerian hormone (AMH),and deficiency of vitamin D may intensify metabolic disturbances. The ultrasound criteria used in adolescent patients prefer the estimation of the ovarian volume or the ratio of ovarian stroma to total ovary, rather than the number of ovarian follicles. PCOS is connected with different metabolic disorders. Post-binding defect in signal transduction is responsible for insulin resistance. This defect results from an impaired activity of the kinase receptor. Moreover, the adipose tissue of PCOS women differs substantially from the tissue of the others according to morphology and function. The adipocytes produce lower amounts of adiponectin, which is an insulin-sensitizing agent. Dyspidemia with high triglycerides and low high density lipoprotein cholesterol concentrations is frequently noticed. Cardio-metabolic risk factors, insulin resistance, and endothelial dysfunction accompany PCOS from the very beginning. Oxidative stress plays a role as a link among systemic inflammation and dysfunction of endothelial cells and abnormal thecal cell action. The treatment efforts in PCOS depend on the patient’s main problems. Modification of diet and lifestyle is the most important recommended advice to each woman independent of age and weight.
