Gamete intrafallopian transfer (GIFT).

Gamete intrafallopian transfer (GIFT) is a new technique of assisted conception appropriate for women with normal fallopian tubes. As 60% of infertile patients have normal and patent tubes (idiopathic infertility, immune causes, male infertility and endometriosis) they can be treated with this technique which is both simpler and more successful than in vitro fertilization.
