Transvaginal gamete intra-fallopian transfer and embryo intra-fallopian transfer

This study describes the conduct and results of a recently developed technique for transvaginal catheterization of the Fallopian tube in order to transfer gametes or early embryos. Transvaginal gamete intra-Fallopian transfer (TV-GIFT) was performed in 46 patients after stimulation with human menopausal gonadotrophin (HMG) and human chorionic gonadotrophin (HCG) and transvaginal oocyte retrieval. This resulted in 11 (23.9%) pregnancies. Eight patients delivered healthy children, including one set of twins. Two patients had abortions at 8 and 11 weeks of gestation and one had an ectopic pregnancy. In a first series of 11 women, oocytes were fertilized in vitro and a maximum of three embryos at the 2- to 8-cell stages were transferred into one tube. Three of the 11 cycles with tubal embryo-stage transfer' (TV-TEST) resulted in clinical pregnancy.
