Matched controlled study to evaluate the effect of endometrial polyps on pregnancy and implantation rates following in vitro fertilization-embryo transfer (IVF-ET).

To determine if endometrial polyps negatively effect outcome following in vitro fertilization-embryo transfer (IVF-ET) and whether hysteroscopic resection improves pregnancy and implantation rates and/or decreases miscarriage rates.Retrospective study with two matched controlled groups (polyps vs no polyps) based on age and previous number of IVF failures. The polyp group was further stratified by whether polypectomy was performed or not.There was no difference or even trend for lower pregnancy rates or higher miscarriage rates with the presence of endometrial polyps.These data do not support the recommendation for hysteroscopic resection of endometrial polyps to aid conception rates.
