Endometriosis is a disorder in which the endometrium, the tissue that lines the lining of the uterus or womb, begins to develop outside the uterine cavity. Endometrial tissue can develop in the ovaries, fallopian tubes, and pelvic region.
Endometriosis symptoms include heavy menstrual flow, pelvic discomfort, and urine or bowel motion pain. Having a direct family member with the condition, starting menstruation early, and not having a child raises the chance of endometriosis. Women between the ages of 25 and 40 are most commonly affected. Women who have endometriosis are more prone to experience infertility or trouble conceiving.

The gold standard of diagnosis and therapy for endometriosis is abdominal ultrasonography or laparoscopy. Medications such as oral contraceptives, GnRH analogs, and injections to inhibit ovarian function are frequently used to begin treatment. Surgery is commonly used as a last option to address the latter stages of this illness.
