gamete intrafallopian transfer
Gamete intrafallopian transfer (GIFT) is a tool of assisted reproductive technology against infertility. Eggs are removed from a woman's ovaries, and placed in one of the Fallopian tubes, along with the man's sperm. The technique, first attempted by Steptoe and Edwards and later pioneered by endocrinologist Ricardo Asch, allows fertilization to take place inside the woman's uterus.
With the advances in IVF the GIFT procedure is used less as pregnancy rates in IVF tend to be equal or better and do not require laparoscopy when the egg is put back.
==Method==
It takes, on average, four to six weeks to complete a cycle of GIFT. First, the woman must take a fertility drug to stimulate egg production in the ovaries. The doctor will monitor the growth of the ovarian follicles, and once they are mature, the woman will be injected with Human chorionic gonadotropin (hCG). The eggs will be harvested approximately 36 hours later, mixed with the man's sperm, and placed back into the woman's Fallopian tubes using a laparoscope.
