Who gets PCOS?

Between 5% and 10% of women between 15 and 44, or during the years you can have children, have PCOS. 1 Most women find out they have PCOS in their 20s and 30s, when they have problems getting pregnant and see their doctor. But PCOS can happen at any age after puberty.

Women of all races and ethnicities are at risk of PCOS. Your risk of PCOS may be higher if you have obesity or if you have a mother, sister, or aunt with PCOS.
