What Increases Your Risk

    Your risk of endometriosis is higher if:

    • You are between puberty and menopause (around age 50). After estrogen levels drop at menopause, your risk disappears.
    • Your mother or sister has or had endometriosis. This makes it more likely you will have severe symptoms. This risk seems to be passed on by the mother.
    • Your menstrual cycles are less than 28 days.
    • Your menstrual flow is longer than 7 days.
    • You started menstruation before age 12.
    • You have never been pregnant.
    • Your uterus, cervix, or vagina has an abnormal shape that blocks or slows menstrual flow.
