Polycystic ovary syndrome: Fertility, prenatal care, pregnancy, and postpartum care.

Polycystic ovary syndrome (PCOS) is a complex, heterogeneous reproductive endocrinopathy affecting 8% to 13% of women in their reproductive years. PCOS has a vast array of clinical manifestations, including metabolic complications, biochemical and phenotypical hyperandrogenism, menstrual cycle dysfunction, and anovulation resulting in infertility. Understanding the relationship of the disorder's pathophysiologic and clinical manifestations is key to successfully managing patients with PCOS. Patients may have different prenatal, perinatal, and postnatal experiences than those who do not have PCOS, and may require a higher level of care or treatment plan adjustments.
