Endometriosis is a chronic and often painful condition where tissue similar to the lining inside the uterus, called the endometrium, starts to grow outside the uterus. This aberrant tissue growth can occur on the ovaries, fallopian tubes, and the tissue lining the pelvis. Rarely, endometrial-like tissue may be found beyond the pelvic region.

Normally, the endometrium thickens and sheds throughout the menstrual cycle and leaves the body during the period. However, any tissue that has grown outside of the uterus becomes trapped.

In the tissue surrounding the ovaries, irritation may occur and cause cysts (called endometriomas) or scar tissue.
