Current perspectives in polycystic ovary syndrome

Abstract

Polycystic ovary syndrome has been viewed primarily as a gynecologic disorder requiring medical intervention to control irregular bleeding, relieve chronic anovulation, and facilitate pregnancy. A large body of evidence has demonstrated an association between insulin resistance and polycystic ovary syndrome. The former condition has an established link with long-term macrovascular diseases such as type 2 diabetes mellitus, hypertension, and atherosclerotic heart disease, consequences that also are observed in women with polycystic ovary syndrome. In addition, chronic anovulation predisposes women to endometrial hyperplasia and carcinoma. The purpose of this review is to examine the clinical course of this syndrome, which spans adolescence through menopause, and suggest a simple and cost-effective diagnostic evaluation to screen the large numbers of women who may be affected. Therapy, which should be individualized, should incorporate steroid hormones, antiandrogens, and insulin-sensitizing agents. Weight loss by way of reduced carbohydrate intake and gentle exercise is the most important intervention; this step alone can restore menstrual cyclicity and fertility, and provide long-term prevention against diabetes and heart disease. Treatment alternatives should be directed initially toward the most compelling symptom. Longitudinal care is of paramount importance to provide protection from long-term sequelae.
