Polycystic ovary syndrome is a common hormonal disorder that affects many women of reproductive age. The name of the disorder came from the observation that women with PCOS often have the appearance of “cysts” along the outer edge of their ovaries when viewed by ultrasound. These “cysts” correspond to immature follicles that have stopped developing due to hormonal imbalance. Polycystic ovaries develop as a consequence of excess ovarian androgen. PCOS can disrupt ovulation or stop it altogether, often leading to subfertility. Women with PCOS may experience excessive hair growth, weight gain, acne, and many other symptoms, ranging from mild to severe.
