The polycystic ovary syndrome is very well known by its high frequency in women, which can get 16% of healthy women and 75% of anovulatory infertile patients. Nevertheless, its etiology and prophylaxy till now remains unclear in the literature. In this work the author discussed on these two problems. According to him the main cause of this pathological pattern would be the diminution of response of ovarian follicles to gonadotropins caused by the presence of androgens, so that no follicle can reach maturity and no ovulation can occur. On the other hand, any cause of diminution of ovarian vascularization such as pelvic inflammatory diseases, adhesion of the adnexa including the ovary may conduct to polycystic ovary. For the prophylaxy, the author suggested that any indication of use of androgenic drugs must be restricted, mostly for young girls and pregnant women to prevent the development of polycystic ovary. Adnexitis would be also treated as soon as possible
