To assess the impact of endometriosis on intracytoplasmic sperm injection
(ICSI) outcome, we have retrospectively evaluated 980 ICSI cycles,
comparing the results of women with and without endometriosis. A total of
101 cycles was identified in which various degrees of endometriosis were
involved, and in the remaining 879 cycles, male infertility was the only
cause of infertility. Ejaculated spermatozoa were microinjected in all
cycles. There was a significant reduction (P = 0.004) in the number of
oocytes retrieved from women with endometriosis as compared to those
without endometriosis. However, there were no significant differences in
either fertilization or pregnancy and implantation rates between women with
or without endometriosis. We conclude that the presence of endometriosis in
patients undergoing ICSI because of severe male infertility does not affect
fertilization, pregnancy and implantation rates, although significantly
fewer oocytes are retrieved from patients with endometriosis.
