Endometriosis reduced oocyte retrieval numbers but did not impact fertilization, blastulation, live birth rates, or miscarriage compared to tubal factor infertility.

Abstract

To investigate the potential effect of endometriosis on embryo development and clinical outcomes, a retrospective analysis of 716 women undergoing their first standard in vitro fertilization (sIVF) cycles (205 endometriosis and 511 with tubal factor infertility) was performed. The endometriosis group included women with an ultrasonographic or surgical diagnosis. Control subjects were women diagnosed with tubal factor infertility by laparoscopy or hysterosalpingogram. The primary outcome of the study was live birth. Cumulative live birth was also assessed in a subgroups analysis. After adjusting for confounders we found no significant difference in fertilization rate, blastulation, top-quality blastocyst, live birth, cumulative live birth (subgroups analysis) and miscarriage rate. In the endometriosis group, the number of retrieved oocytes was smaller (6.94 ± 4.06 Vs 7.50 ± 4.6, adjusted p < 0.05). We observed a statistically significant difference in the percentage of day-3 embryos with ≥8 blastomeres (33.12 ± 22.72 endometriosis vs, 40.77 ± 27.62 tubal factor, adjusted p < 0.01) and a negative correlation between the presence of endometriomas and a number of retrieved oocytes [B coefficient =-1.41, 95%CI (-2.31-0.51), adjusted p = 0.002]. Our results suggest that endometriosis affects the number of retrieved oocytes but not embryo development and live birth.
