PCOS

Also written as: PCOS — Polycystic Ovary Syndrome

Endocrine disorder in adolescent girls characterized by irregular periods, hyperandrogenism, and polycystic ovarian morphology.

Full Definition

Polycystic ovary syndrome is a common endocrine disorder affecting adolescent girls and women of reproductive age, characterized by chronic anovulation, clinical or biochemical hyperandrogenism, and polycystic ovarian morphology on ultrasound. In adolescents, diagnosis can be challenging due to normal menstrual irregularity and physiologic changes during pubertal transition. Clinical manifestations include oligomenorrhea or amenorrhea, hirsutism, acne, alopecia, obesity, and insulin resistance. PCOS is associated with increased risk of metabolic syndrome, type 2 diabetes, and cardiovascular disease. Diagnosis typically requires at least two of three criteria: oligo/anovulation, hyperandrogenism, and polycystic ovaries. Treatment is symptom-directed and may include hormonal contraceptives for menstrual regulation, antiandrogens for hirsutism, and metformin for insulin resistance.

Usage

Usage note: Specify diagnostic criteria used, as these may vary between adolescent and adult populations.
