Definition of Gamete intrafallopian transfer (GIFT)
Gamete intrafallopian transfer (GIFT) definition - medical term
A technique in which the male and
female germ cells required to begin formation of a human embryo are injected into
a woman's fallopian tubes of the female for fertilization. This technique is one
of the methods doctors use to overcome infertility, the inability of couples to
produce offspring on their own.
Gametes (germ cells) in males are the spermatozoa, or sperm, and those in females
are ova, or eggs. After a sperm fertilizes an egg in the fallopian tubes, the egg
implants itself in the uterus (womb), a hollow organ that lodges and nourishes the
embryo during its development.
The term "intrafallopian" means "inside the fallopian tubes." ("Intra," a Latin
word, means "within" or "inside.") Thus, in the GIFT technique, fertilization takes
place inside the body of the female. By contrast, in the technique of in vitro fertilization
(IVF), eggs are fertilized outside the body.
"Gamete" is derived from the Greek word "gamete" (wife) and "gamein" (to marry).
