Embryo transfer to the uterus or the fallopian tube after in vitro fertilization yields similar results.
The outcome of ZIFT and IVF-ET was compared in consecutive nontubal factor patients in a prospective fashion. Groups did not differ in characteristics and were matched by the number of prezygotes/pre-embryos transferred. Overall, implantation, pregnancy, miscarriage, and ongoing PRs were not statistically different. These results suggest that ZIFT offers no significant advantage over IVF-ET for the treatment of nontubal infertility.
