Effect of Endometriosis on Cycle Outcome of in Virto Fertilization-embryo Transfer

Objective:To investigate the effect of endometriosis on in vitro fertilization-embryo transfer(IVF-ET) outcome.Methods:In this retrospective study,69 infertile patients with endometriosis and 73 patients with tubal-infertility undergoing IVF-ET were included.According to their clinical pathological type,69 cases of endometriosis were divided into two groups: group A as ovarian endometriosis,group B as peritoneal endometriosis.The requirement to gonadotropin(Gn),the number of oocytes,the fertilization rate,the clinical pregnancy rate,the implantation rate,and delivery rate were compared among three groups.Results:More requirements to Gn and lower number of oocytes in the endometriosis patients compared to those tubal-infertility.There were no significant difference in fertilization rate,clinical pregnancy rate,implantation rate,and delivery rate among three groups.Conclusions:Endometriosis patients present a poorresponse to controlled ovarian hyperstimulation that results a decreased numbers of oocytes.Fortunately,it does not deleteriously affect the IVF-ET outcome.
