I have Endometriosis, does this affect my fertility and also success with IVF?

Endometriosis is a condition where cells that usually remain confined to the cavity of the uterus, grow outside of the uterus usually on or in the ovaries and also on the surface of the pelvic plain and may also decrease the chances of natural conception by about one-third. Patients who require IVF who have endometriosis still have the same chances of a successful outcome as patients of the same age without endometriosis as long as immunological factors that may accompany endometriosis are identified and treated appropriately.
