A condition, also called Stein–Leventhal syndrome, that is characterized by oligomenorrhea or amenorrhoea (scanty or absent periods), infertility, hirsutism (excessive hairiness), and obesity. Often, there are multiple ovarian cysts. Most women with polycystic ovaries begin menstruation at a normal age, but after a year or two periods become highly irregular and then cease. Hirsutism and obesity occur in about 50 per cent of cases. The condition results from an imbalance of two gonadotrophin hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This hormonal imbalance is associated with raised levels of testosterone and oestrogen. Treatments include clomifene and oral contraceptives. Polycystic ovaries are often associated with high oestrogen levels in the body, which increase the risk of endometrial cancer (see uterus, cancer of); treatment with progesterone may be recommended for this problem.
