The migrated tissue retains its character and changes with the fluctuations of the menstrual cycle, bleeding at the time of menstruation menstruation, periodic flow of blood and cells from the lining of the uterus in humans and most other primates, occurring about every 28 days in women. Menstruation commences at puberty (usually between age 10 and 17).

Symptoms of endometriosis can be absent or can include painful menstruation, severe abdominal or low back pain, painful intercourse, and rectal bleeding at the time of menstruation. Symptoms often disappear with pregnancy, but 30%–40% of women who have endometriosis are infertile.

The cause of endometriosis is unknown. One hypothesis is that the endometrial fragments move back up through the fallopian tubes rather than leaving the body with the menstrual flow. Diagnosis is by pelvic examination or laparoscopy. Treatment, which depends on the severity of the disease, may include a course of oral contraceptives, or danazol if the patient is trying to conceive. In severe cases surgical removal of the cysts or hysterectomy hysterectomy (hĭstərĕk`təmē), surgical removal of the uterus .

endometriosis

Disorder of the female reproductive system in which endometrium (uterine lining) grows in an abnormal location because some endometrial fragments traverse the fallopian tubes into the abdominal cavity and become embedded on structures there, usually the ovaries, rather than exiting the uterus via the vagina (during menstruation). Symptoms include pain on menstruation, sexual intercourse, defecation, and/or urination; heavy menstrual flow; blood in the urine; and infertility. Diagnosis is best made by laparoscopy. Treatment includes surgery and hormones to suppress ovulation for six to nine months.
