Exploring PCOS Throughout the Body

Polycystic ovary syndrome (PCOS) is a common hormone disorder where fluid-filled sacs (cysts) form in the ovary and produce high levels of androgen hormone, resulting in immature egg development and irregular ovulation.

PCOS affects nearly 5 million women in the United States, but an estimated 70% of women with PCOS remain undiagnosed.

While PCOS is often diagnosed after a woman experiences menstruation issues or infertility, this chronic condition impacts more than just ovulation. In the Exploring PCOS Throughout the Body Fact Sheet, learn how PCOS impacts mental health, heart health, and reproductive health in women.

As of May 2026, Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the new name for the condition previously known as Polycystic Ovary Syndrome (PCOS). PCOS reduced a complex, long term hormonal or endocrine disorder to a misunderstanding about ‘cysts’ and a focus on ovaries, contributing to missed diagnoses and inadequate treatment. PMOS will raise awareness and improve diagnosis and care. This name change will take place over a 3-year period. SWHR will use both PCOS and PMOS during this period.
