Fertility problems
The main complication of endometriosis is difficulty getting pregnant (subfertility) or not being able to get pregnant at all (infertility). Surgery can improve fertility by removing endometriosis tissue, but there is no guarantee that this will allow you to get pregnant.
Adhesions and ovarian cysts
Other problems include the formation of adhesions, which are 'sticky' areas of endometriosis tissue that can fuse organs together, and endometriomas (fluid-filled cysts in the ovaries), which can occur when the endometriosis tissue is in or near the ovaries. In some cases, endometriomas can become very large and painful.
Both of these complications can be removed through surgery, but may recur if the endometriosis returns.
