Zygote intrafallopian transfer (ZIFT) is an infertility treatment used when a blockage in the fallopian tubes prevents the normal binding of sperm to the egg.Egg cells are removed from a woman's ovaries, and in vitro fertilised. The resulting zygote is placed into the fallopian tube by the use of laparoscopy.The procedure is a spin-off of the gamete intrafallopian transfer (GIFT) procedure. ZIFT has a success rate of 64.8% in all cases.he resulting zygote is placed into the fallopian tube by the use of laparoscopy. The procedure is a spin-off of the gamete intrafallopian transfer (GIFT) procedure. ZIFT has a success rate of 64.8% in all cases.
After fertilization, the zygote begins to divide rapidly. Twenty-four hours after fertilization, the zygote contains two cells, and three days after fertilization the zygote has 16 cells and is called a morula. The cells continue to divide and form a hollow bundle called a blastocyst. The blastocyst implants in the endometrium, and the cells begin to form the embryo. The embryo is present at five to six days after the zygote is fertilized. The embryo is a clump of cells inside the formerly hollow blastocyst, and is surrounded by the trophoblast.
