title: Polycystic ovary syndrome.
abstract: Polycystic ovary syndrome (PCOS) is the most common female endocrinopathy, affecting 5-10% of the female population. It involves overproduction of ovarian androgens leading to a heterogeneous range of symptoms including hirsutism, acne, anovulation and infertility. Hyperinsulinaemia, exacerbated by obesity, is often a key feature. Treatment depends on the presenting symptoms, which may often be ameliorated by weight loss where relevant. Anti-androgen preparations are used for hyperandrogenic symptoms, and clomiphene citrate (CC) is the first-line treatment for anovulation and infertility. Aromatase inhibitors are being investigated as an alternative to CC. Failure to conceive with CC can be treated in a number of ways, including the addition of insulin-lowering agents (mainly metformin), low-dose gonadotrophin therapy or surgically by laparoscopic ovarian drilling. Although the exact aetiology of PCOS is not known, the therapeutic alternatives provide reasonably successful symptomatic treatment.
