Transcervical intrafallopian transfer of zygotes.

Reportedly, gamete intrafallopian transfer and zygote intrafallopian transfer are successful methods in assisted conception. This pilot study describes the experiences and results of a recently developed technique of vaginal transcervical intrafallopian transfer. In a group of 38 women with unexplained infertility, oocytes were retrieved. In 25 patients, pronucleate embryos were transferred to the fallopian tubes. A positive pregnancy test was reported in 8 cases. Considerations pertaining to this method and technical implications are discussed.
