polycystic ovary syndrome
Also written as: PCOS — Polycystic Ovary Syndrome
Hormonal disorder characterized by irregular ovulation, elevated androgens, and polycystic ovarian morphology.
Full Definition
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age, occurring in 6-12% of women. The condition is characterized by three main features: irregular or absent ovulation, clinical or biochemical signs of hyperandrogenism (excess male hormones), and polycystic ovarian morphology on ultrasound. PCOS often leads to infertility due to ovulatory dysfunction and is associated with insulin resistance, increased risk of diabetes, and metabolic syndrome. Treatment approaches vary depending on whether fertility is desired and may include lifestyle modifications, hormonal contraceptives, or ovulation induction agents.
Usage
