ARTs (Assisted Reproductive Technologies) are helpful to humans as they enable the infertile couple to have children. The ART techniques ZIFT and GIFT are different  because ZIFT (Zygote Intra Fallopian Transfer) is related to embryo transfer in the test-tube programme. In this technique, the zygote or embryo up to 8 blastomeres is  transferred into the Fallopian tube. GIFT(Gamete Intra Fallopian Transfer) is the technique in which ovum collected from a donor female is transferred into the Fallopian  tube of another female, who cannot produce an ovum, but can provide suitable conditions for fertilisation and further development. Whereas, IUT (Intra Uterine Transfer)  is the technique in which embryo of more than 8 blastomeres are transferred into the uterus.
