Endometriosis IVF success rates are reduced compared to those who do not have this condition. IVF is a method of assisted conception by transplanting a fertilized egg directly into a woman’s uterus. Endometriosis mostly invades the ovaries and leads to infertility mainly related to the abnormal proliferation of endometrial cells, which leads to adhesions around the fallopian tubes or makes the ovaries function in such a way that it causes the patient to be infertile. Endometriosis affects the entire pelvic environment, and the success rate of doing IVF is reduced compared to those without endometriosis. Especially in stage 3 or 4 endometriosis, the success rate is even lower. It is recommended that patients with endometriosis should be treated actively to help them conceive as soon as possible.
