How many people are affected by or at risk for endometriosis?

Endometriosis is most common in women in their 30s and 40s,1 but it can affect any female who menstruates.

Studies show that women are at higher risk for endometriosis if their:

  • Mother, sister, or daughter had endometriosis (raises the risk about sixfold)1
  • Periods started at an early age (before age 11)2
  • Monthly cycles are short (less than 27 days)2
  • Menstrual cycles are heavy and last more than 7 days2

Studies also show that some factors may lower the risk for endometriosis, including:

  • Pregnancy
  • Starting menstruation late in adolescence3
  • Regular exercise of more than 4 hours a week2
  • Low amount of body fat
