Which organ is affected by endometriosis?

I suffered with it severely to the point I had to have an operation.

Sharon Fay, I, too, had to resort to surgery many years ago. I was told that it was misplaced endometrial tissue, not "endometrial-like" tissue. If it quacks like a duck... l hope the surgery solved your problem, as it did mine. Wishing you good health!

new info for me.thanks
