Oocyte donation and gamete intrafallopian transfer in premature ovarian failure

Gamete intrafallopian transfer (GIFT) was performed in eight patients with premature ovarian failure (POF), using donated oocytes. The steroid replacement protocol consisted of the administration of increasing dosages of 17 beta-estradiol (E2) and progesterone (P). Hormonal replacement was maintained until day 100 of gestation. All patients underwent an evaluation cycle in which serum levels of E2 and P were monitored and an endometrial biopsy was performed on day 21 or 22. All cases of GIFT were performed between days 12 and 15. Six clinical pregnancies were achieved in eight cycles (75% success rate). Three patients delivered and three are in their second or third trimester. No ectopics or miscarriages occurred. These results offer a promising approach for the establishment of fertility in agonadal patients.
