In-vitro fertilization, gamete- or zygote intra-fallopian transfer for the treatment of male infertility.

This retrospective study compares in-vitro fertilization and embryo transfer (IVF-ET), gamete intra-Fallopian (GIFT) and zygote intra-Fallopian transfer (ZIFT) for the treatment of male infertility in 266 couples (n = 318 cycles). The IVF-ET technique revealed a total pregnancy rate of 14.1% per cycle and 29.1% per transfer. The conception rate with GIFT was 17.8%; an abortion rate of 50% was noted. The ZIFT procedure scored a 20.9% total pregnancy rate per cycle and 33.3% per transfer. The cumulative take home baby rates per couple for IVF-ET, GIFT and ZIFT were 13.5, 7.0 and 20.0%, respectively.
