Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders and causes of infertility in women in reproductive age. Diagnostic criteria of PCOS in adult women include: ovulation disorders, hyperandrogenism and polycystic ovaries. According to most recommendations, 2 out of these 3 criteria are confirm the diagnosis of PCOS. In girls during puberty and in the first years after menarche, different diagnostic criteria of menstrual disorders should be taken into account (variable length of menstrual cycles, monophasic cycles) and the limited usefulness of ultrasound examination for PCOS diagnosis within 8 years after menarche. Fairly extensive differential diagnosis is also necessary, especially – exclusion of adrenal hyperandrogenism. Moreover, the diagnostic criteria of PCOS do not take into account the metabolic disorders found in most patients (obesity, insulin resistance, type 2 diabetes), which should be diagnosed as early as possible and treated appropriately. This is especially true for teenagers, in whom the unequivocal diagnosis of PCOS or its exclusion may be very difficult. Current recommendations regard hormonal contraception as the first-line therapy in PCOS, in both adult women and adolescents. Together with its beneficial effect on the reduction of hyperandrogenism and obtaining regular bleeding (which in fact are not menstruations), the unfavorable metabolic effects of hormonal contraception are emphasized, as well as the inadequacy of its use if it is expected to achieve or restore ovulation and fertility. The latest reports indicate the legitimacy of treatment aimed at correcting disorders of carbohydrate metabolism and its greater effectiveness compared to the use of oral contraceptives in both adult women and girls with PCOS. In the pharmacotherapy of insulin resistance, metformin is of fundamental importance, the use of pioglitazone, GLP-1 receptor agonists or inositols is also proposed. Adequate lifestyle and dietary modification are of major importance in the treatment and prevention of PCOS. The mechanisms of "inheritance" of PCOS and insulin resistance with the participation of epigenetic modifications are still better understood, taking into account the effects of exposure to androgen excess in utero, intrauterine growth retardation, and maternal obesity and hyperalimentation. This creates new possibilities for PCOS prophylaxis.
