UNLABELLED: Polycystic ovary syndrome (PCOS) is a common disorder of reproductive-aged women. It affects between 3.4-6.8% of this population. Common clinical symptoms of PCOS include menstrual irregularities, hirsutism, and often obesity. Long-term sequelae include anovulatory infertility, endometrial carcinoma, and an increased risk for cardiovascular disease due to type II diabetes mellitus, dyslipidemia, and systolic hypertension.

It is important for practitioners to recognize and distinguish PCOS from other disorders in its differential.
