The Retrospective Analysis on the Outcome of IVF-ET for Patients with Infertility by Endometriosis

Objective:Tto investigate and analyze the effect of endometriosis on in vitro fertilization and embryo transfer according to the comparison between the infertility patients with endometriosis or tubal-factor.Methods:Twenty-two patients with endometriosis(group A) underwent 23 cycles of IVF-ET.The matched control group with tubal-factor infertility(group B) consisted of 36 cycles in 36 patients.These groups were analyzed regarding stimulation,fertilization,cleavage,implantation,and pregnancy outcome.Results:The requirement of gonadotropin and the days of controlled ovarian hyperstimulation(COH) higher(P0.05),but the cleavage,fertilization,implantation,and pregnancy rate did not differ between the two groups.Conclusion:Our results show that women with endometriosis presented a poor ovarian response to controlled ovarian hyperstimulation,but the ability for the oocyte to be fertilized,the implantation and pregnancy rate were similar to the tubal-factor infertility.
