Current Perspectives in Polycystic
MARILYN R. RICHARDSON, M.D., University of Kansas Medical Center, Kansas City, Kansas
Polycystic ovary syndrome has been viewed primarily as a gynecologic disorder requiring
medical intervention to control irregular bleeding, relieve chronic anovulation, and facil-
itate pregnancy. A large body of evidence has demonstrated an association between
insulin resistance and polycystic ovary syndrome. The former condition has an estab-
lished link with long-term macrovascular diseases such as type 2 diabetes mellitus, hyper-
tension, 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. (Am Fam Physi-

In many women the symptoms are easily recognizable,
but ethnicity influences the extent of symptoms, especially
with regard to hirsutism and obesity. Therefore, taking a
diligent history with regard to menstrual patterns is cru-
cial to help establish the diagnosis. The National Institute
of Child Health and Development16 held a consensusmeeting to develop the following diagnostic criteria for
