Medical Definition of ENDOMETRIOSIS
: the presence and growth of functioning endometrial tissue in places other than the uterus that often results in severe pain and infertility—see adenomyosis
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.
