Polyendocrine Metabolic Ovarian Syndrome (PMOS) — Formerly PCOS

Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the updated medical name for the condition previously known as Polycystic Ovary Syndrome (PCOS). The new terminology reflects a growing understanding that this condition affects multiple hormonal and metabolic systems throughout the body, not just the ovaries. As the medical community adopts this updated terminology, you may see both PMOS and PCOS used interchangeably during the transition.

PMOS, formerly known as PCOS, affects almost 1 in 10 women and is the most common endocrine disorder among women of reproductive age.

Symptoms may include irregular periods, excess body or facial hair, acne, and difficulty maintaining a healthy weight. PMOS also may be associated with depression, difficulty getting pregnant, predisposition to type 2 diabetes, and other long-term health problems.

The UCSF Multidisciplinary PMOS Clinic offers an integrated approach to treating polyendocrine metabolic ovary syndrome. Our patients see a team of specialists in reproductive endocrinology, dermatology, nutrition, psychology, and genetics. We work together with each patient to create an individualized treatment plan.
