Gamete intrafallopian transfer as treatment for infertility associated with endometriosis.

Forty-six patients with endometriosis-associated infertility underwent 59 GIFT cycles. The pregnancy rate per cycle was 30.5%. The presence of endometriomas in 11 patients did not affect this rate adversely. We conclude that, provided at least one fallopian tube is patent, GIFT compensates effectively for the possible causes of infertility in these patients.
