Endometriosis is a painful disorder in which tissue similar to the tissue that normally lines the inside of your uterus grows outside your uterus.
Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis.
The main complication of endometriosis is impaired fertility. Approximately one-third to one-half of women with endometriosis have difficulty getting pregnant.
Endometriosis can obstruct the tube and keep the egg and sperm from uniting.
That said, many patients with mild to moderate endometriosis can still conceive and carry a pregnancy to term.
Secondly, those with endometriosis may be more likely to develop ovarian cancer. But the overall lifetime risk of ovarian cancer is low to begin with.
