TRANSVAGINAL EMBRYO-TRANSFER DURING THE ZYGOTE INTRAFALLOPIAN TUBE TRANSFER PROCEDURE

OBJECTIVE: Our purpose was to evaluate a tactile nonultrasonographical ly directed approach to transvaginal tubal cannulation and embryo tran sfer during the zygote intrafallopian tube transfer procedure. STUDY D ESIGN: We studied the application of the tactile approach to transvagi nal tubal cannulation and embryo transfer in 68 consecutive zygote int rafallopian tube transfer cycles. RESULTS: The tactile approach to tra nsvaginal tubal cannulation and subsequent embryo transfer was success ful 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 eas ily 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.
