Two centers combined data on 152 in vitro fertilization embryo replacement and 90 gamete intrafallopian transfer generated pregnancies. The outcomes of the pregnancies with respect to abortion, ectopic gestation, and multiple gestation were evaluated independently by method and by center. Only with multiple gestation by center was a difference seen. Variables examined included estradiol levels, luteal phase support, maternal age, and prior reproductive history, and the number of eggs or embryos replaced.
