title: Gamete intrafallopian transfer.
abstract: GIFT involves placement of a donor's oocyte into a surrogate's oviduct. Fertilization and embryo development occur within the recipient's reproductive tract. GIFT provides a viable method to obtain pregnancies from subfertile mares for which embryo transfer has been nonproductive. Currently, pregnancy rates after GIFT have been variable, although high success rates have been reported recently. Further refinement of techniques should allow GIFT to be used in research and commercial programs.
