Twenty-six couples with unexplained infertility (UI), nine women with repeated failures of artificial insemination with donor semen (AID), three women with mild endometriosis, three with periadnexal adhesions, one with hostile (not immunologic) cervical mucus, and one couple in which the male partner was afected by asthenospermia were treated by the gamete intrafallopian transfer (GIFT) technique. Three different protocols of controlled ovarian hyperstimulation were used, and an adequate follicular growth and oocyte maturation were achieved in all cases. Seventeen pregnancies were obtained, for a global pregnancy rate of 38.6%. Two pregnancies (11.7%) ended in clinical abortions, and one (5.8%) was a tubal pregnancy. Of the ongoing pregnancies, one is twin and two are triplets. Seven pregnancies (six ongoing, one abortion) were obtained in the UI group (26%), six (all ongoing) in the failed AID group (66.6%), two continuing pregnancies in the three patients with endometriosis (66.6%); the tubal pregnancy and one clinical abortion occurred in the group with adnexal adhesions. No pregnancies were obtained in the patient with hostile cervical mucus and in the couple with infertility presumably due to poor semen. These encouraging results and the simplicity of the technique suggest that GIFT could be an effective approach that could be programmed during a well-timed laparoscopy where persistent infertility exists in association with apparently normal fallopian tubes.
