A common hormonal condition marked by irregular ovulation, androgen excess, and/or polycystic ovaries.
Also known as: polycystic ovary syndrome
Polycystic ovary syndrome (PCOS) is a common hormonal disorder that can cause irregular periods, signs of excess androgens such as acne or extra hair growth, and many small follicles on the ovaries.
It is frequently associated with insulin resistance. Diagnosis commonly uses the Rotterdam criteria, requiring two of three defining features.
