TRANSVAGINAL EMBRYO-TRANSFER DURING THE ZYGOTE INTRAFALLOPIAN TUBE TRANSFER PROCEDURE

OBJECTIVE: Our purpose was to evaluate a tactile nonultrasonographically directed approach to transvaginal tubal cannulation and embryo transfer during the zygote intrafallopian tube transfer procedure. STUDY DESIGN: We studied the application of the tactile approach to transvaginal tubal cannulation and embryo transfer in 68 consecutive zygote intrafallopian tube transfer cycles. RESULTS: The tactile approach to transvaginal tubal cannulation and subsequent embryo transfer was successful in 93% of couples. Pregnancy occurred in 16 of the 63 (25%) women undergoing a successful transvaginal embryo transfer. CONCLUSION: The tactile approach to transvaginal tubal cannulation was found to be easily learned and provided a safe and convenient method of tubal embryo transfer. This low-cost approach, which has application to transfer of both embryos and gametes, deserves further study.
