[Ovum donation and gamete intrafallopian transfer (GIFT): a new reproduction concept].

Gamete intrafallopian transfer (GIFT) was performed in 11 patients with premature gonadal failure and infertility, with oocyte donation. The sustitutive estrogen therapy with Estradiol Valerinate and Progesterone was maintained up to 100 days after the transfer. In all the cases GIFT was performed between the day 13 and 70 of the cycle. There were 5 pregnancies out of 11 cycles (success rate of 45.4%), one ended with a live child and the four others are on their first, second and third trimester. We are presenting a modified and simplified new protocol for hormonal replacement and our results suggest a new and wide "endometrial window" for the management of this patients. This results offer a promising future for patients with premature gonadal failure.
