A controlled study between the use of gamete intrafallopian transfer (GIFT) and in vitro fertilization and embryo transfer in the management of idiopathic and male infertility.

A randomized controlled trial comparing the use-effectiveness between gamete intrafallopian transfer (GIFT) and in vitro fertilization (IVF) and embryo transfer (ET) procedures showed no significant difference in pregnancy rates in the management of patients presenting with idiopathic or male infertility. The cost-effectiveness of GIFT appears superior to IVF and ET with laparoscopic oocyte collection, but comparable to IVF-ET with ultrasonic oocyte collection. The lack of data on the fertilizing capacity of sperm in GIFT procedures in cases of male infertility is a real disadvantage and currently precludes the management of severe male infertility with this method.
