Zygote intrafallopian transfer
Zygote intrafallopian transfer (ZIFT) is a variation on a procedure called in vitro fertilization. With in vitro fertilization, an egg is fertilized in the laboratory in a glass petri dish. After the egg has been fertilized it is returned to the womb. Once in the womb, the fertilized egg starts to divide and then develops as any other fetus.
The zygote transfer is a bit different. A zygote is a fertilized egg before it starts to divide. In this procedure, the eggs are fertilized in a petri dish. They are transferred into the fallopian tubes of the mother. Once in the mother, the zygote begin their natural division process. The difference between the two procedures is very slight.
