This retrospective analysis of IVF/ICSI cycles found that implantation, pregnancy, and delivery rates were similar in women with endometriosis compared to those with tubal or male factor infertility.

Abstract

Purpose To reconsider the implantation and delivery rates which occurred six years later in women with endometriosis from the Yale IVF Programme. Methods Five hundred and ninety-seven consecutive IVF and ICSI treatment cycles were analyzed retrospectively. Patients with endometriosis (n=130; 258 cycles) were compared with an age-matched control group with tubal infertility (n=104; 206 cycles) and also with a group with male infertility (n=59; 133 cycles). Data from the endometriosis group were analyzed further in minimal-mild (144 cycles) and moderate-severe (114 cycles) subgroups. All the patients underwent laparoscopy prior to IVF treatment. Results Fewer oocytes were retrieved and similar fertilization (59% vs. 61%), implantation (12.3% vs. 16%), and delivery (23.7% vs. 26.3%) rates were found in patients with endometriosis compared to tubal infertility. A trend towards reduced pregnancy rate per transfer (17.5%) in the male infertility vs. endometriosis or tubal infertility groups (34% and 37.8% respectively) was observed. The number of embryos transferred in each group was comparable. Analysis of first cycles only across all groups revealed that the implantation rate did not have any statistically significant differences in the endometriosis versus the tubal or male infertility groups. Within the endometriosis group, the implantation, pregnancy, and delivery rates were similar in subgroups. Conclusions We conclude that in patients with endometriosis, implantation, pregnancy, and delivery rates are similar with tubal factor infertility, and higher compared to male infertility. Our results suggest that embryo quality and uterine receptivity remain unaffected in women with endometriosis.
