Up to 1 in 10 women of reproductive age is affected by endometriosis, a condition that is characterized by endometrial-like tissue manifesting in the pelvis or abdomen external to the uterus. Approximately two-thirds of patients with endometriosis will experience endometriomas or cysts on the ovaries that are visible on ultrasonography; these cysts are correlated with higher pain levels and damage to healthy ovarian tissue.
