Excess coarse, dark hair growth in a male pattern in women, such as on the chin, upper lip, chest, or abdomen.
Why it matters for PCOS
Hirsutism is one of the most commonly noticed features of PCOS, and it usually reflects higher levels or activity of androgens (male hormones). Androgens stimulate hair follicles in certain areas to produce coarser, darker hair. For this reason, hirsutism is one of the clues a doctor weighs when assessing the likelihood of PCOS, alongside your menstrual cycle pattern and hormone blood tests.
Hirsutism is a clue, not a diagnosis on its own. If hair growth appears suddenly, rapidly, or with other fast hormone-related changes, get a doctor’s review to investigate the cause.
