Unilateral gamete intrafallopian transfer: the preferred method?

Pregnancy occurred in 8 of 14 patients with the unilateral transfer of three or four oocytes at GIFT procedures. These results suggest that unilateral GIFT may be at least as successful as the bilateral approach. It would appear that unilateral GIFT rather than in vitro fertilization should be used for patients with one normal fallopian tube, and if the pregnancy rates with unilateral GIFT are substantiated, then this would be preferable to the bilateral approach, as operating time is shorter and there is less risk of trauma to the fallopian tubes at the time of gamete transfer.
