Design: Retrospective case control study. Setting: Academic medical center. Patient(s): The study group consisted of 68 women who previously undergone laparoscopic surgery for advanced-stage endometriosis. The control group included 106 women with tubal-factor infertility. The women with endometriosis underwent 133 IVF-ET cycles and the control group 208 cycles. Intervention(s): Controlled ovarian hyperstimulation and IVF-ET. Main Outcome Measure(s): Response to gonadotropins, fertilization, cleavage, implantation, pregnancy, miscarriage, and live birth rates. Result(s): Lower peak E2 levels, higher total gonadotropin requirements, lower oocyte yield, and higher cancellation rates were found in women with endometriosis compared with tubal-factor control subjects. However, no differences were found in fertilization, cleavage, implantation, pregnancy, miscarriage, and delivery rates between the endometriosis and tubal-factor groups. Conclusion(s): Women with advanced-stage endometriosis who have undergone previous surgery respond less well to gonadotropins than women with tubal-factor infertility. However, implantation, pregnancy, and delivery rates are similar, suggesting that embryo quality and uterine receptivity remains unaffected despite diminished ovarian reserve in women with endometriosis. © 2007 American Society for Reproductive Medicine.
