GIFT

A technique in which the male and female cells required to begin reproduction are injected into the 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.

The acronym GIFT stands for Gamete Intrafallopian Transfer.

Gametes in males are called spermatozoa, or sperm, and gametes in females are called ova, or eggs.

After 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, eggs are fertilized outside the body.

'Gamete' is derived from the Greek word 'gamete' (wife) and 'gamein' (to marry).
