Gamete intrafallopian transfer involves a direct transfer of both huma
n gametes, sperm and oocytes, into the fallopian tube. Since the first
report of a successful pregnancy following the use of this technique
by Asch et al in 1984, its role in the treatment of infertile women wi
th patent tubes has been established. Recent data demonstrate a 34.4%
clinical pregnancy rate, with the highest pregnancy rate achieved in i
nfertile women due to endometriosis or unexplained infertility.
