Gw. Patton et al., TRANSVAGINAL EMBRYO-TRANSFER DURING THE ZYGOTE INTRAFALLOPIAN TUBE TRANSFER PROCEDURE, American journal of obstetrics and gynecology, 171(2), 1994, pp. 359-364
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.
