Copper-T is a device that prevents
Copper T is a small, T-shaped intrauterine contraceptive device (IUCD). The horizontal bar of which fits into the wide top of the uterus and the vertical bar extends down the uterus. It makes the uterus and fallopian tubes produce fluid that kills sperm. This fluid contains white blood cells, copper ions, enzymes, and prostaglandins. Copper ions, released by the IUD, is a spermicide and it kills sperm before it can fertilize the egg. Since fertilization does not occur, implantation of the blastocyst is not possible.

In this process, the eggs of the donor woman are removed and in a form of mixture with sperm transferred into fallopian tube of another woman who cannot produce ovum, but can provide suitable environment for fertilization. Thus in GIFT, site of fertilization is fallopian tube, not laboratory.
