[Effects of ovarian and peritoneal endometriosis on fertility. Experimental study].

Fertility after ovarian and peritoneal endometriosis experimentally induced has been studied. The fertility rate in the animals with ovarian endometriosis was decreased of 40% and the same reduction was found in the animals with peritoneal endometriosis. Not only the direct effect from adhesion formation, but also changes in the peritoneal fluid or its constituents are proposed as causes of endometriosis-associated infertility.
