In GIFT, the gamete (ova) is collected from the female donor and is transferred into the fallopian tube. At the ampullary-isthmus junction of the fallopian tube, the fertilisation process occurs.
If the embryo with more than eight blastomeres is transferred to the uterus of the mother or the surrogate mother, then this is called intrauterine transfer.
If the zygote (with up to 8 blastomeres) is transferred to the fallopian tube, then it is called the zygote intrafallopian transfer (ZIFT).
