Endometriosis is the condition where the lining of the uterus (a.k.a. the endometrium) grows outside the uterus, commonly on the ovaries, outer surface of the uterus, fallopian tubes, and the pelvis. It can also grow on the bowel and bladder. In rare cases it can also spread to distant parts of the body like the lungs, nose, throat and brain. Endometriosis is a major debilitating disease that affectsup to 10% of all women in the reproductive age and up to 60% of women with infertility. Patients with endometriosis usually have pelvic pain, pain with menses, pain with intercourse, or may present with difficulty in conceiving children. It is important to note, some patients have no symptoms other than infertility.Unfortunately, laparoscopy is still the gold standard in diagnosing this disease and currently, the average time between the start of symptoms and the actual diagnosis is 5.5 years. It may start very early in life, at the start of the first menses and continue all the way up to premenopausal years.
