Oocyte donation by gamete intra-fallopian transfer to amenorrhoeic and cycling patients given replacement steroids.
Thirteen procedures of oocyte donation by the gamete intra-Fallopian transfer (GIFT) technique are described. The patients included six women with premature ovarian failure, four normally cycling women with unexplained infertility who responded poorly to super-ovulation induction in preparation for GIFT, and lastly one woman carrier of a 16/21 balanced translocation. Two patients had oocytes donated on two occasions. Oocyte donors were recruited either among the patients' relatives (n = 4), or among GIFT or IVF patients (n = 8), who altruistically donated their extra oocytes. Donors were superovulated and oocytes collected laparoscopically or vaginally under ultrasound guidance. Donors did not suffer any complications. Recipients were given exogenous estrogens, and exogenous progesterone was added from the day of donation. Seven clinical pregnancies were obtained (53.8% per attempt); one set of triplets aborted at 14 weeks. Donation took place on replacement day 12-18 and pregnancies were obtained in patients receiving oocytes throughout this temporal window. The increasing availability of embryo-freezing facilities will probably reduce the number of ova available for donation. Therefore, the patients' families may become a precious source of donated eggs, especially for those patients having large families, with strong family ties.
