Gamete intrafallopian transfer: different routes of transfer

The Authors report their own experience and results using different approaches to oocyte pick-up and gamete transfer for gamete intrafallopian transfer (GIFT). The overall pregnancy rate of GIFT is 35.86% (66 pregnancies on 184 cases of GIFT). The Protocol I (Laparoscopic oocyte retrieval and gamete transfer) is presently the more used and gives better clinical results (pregnancy rate of 37.7%); in the Author's opinion, the protocols III (echographic pick-up + IVF + laparoscopic delayed zygote intrafallopian transfer (ZIFT), and VII (Laparotomic pick-up and transfer) are interesting complementary techniques for GIFT.
