[Polycystic ovary syndrome II. Endocrinology and metabolism]

The polycystic ovary syndrome (PCOS) is diagnosed by the simultaneous presence of polycystic ovaries by ultrasound together with clinical and biochemical signs of hyperandrogenaemia. Recently, it has been shown that a majority of PCO patients exhibit metabolic abnormalities, i.e. android obesity, insulin resistance and dyslipidaemia, all of which dispose to "civilized" life-style diseases such as cardiovascular disease and non-insulin dependent diabetes. PCOS is therefore not merely a gynaecological curiosity, but an endocrinopathy with multisystem sequelae. The endocrinological and metabolic aspects of the disease are discussed.
