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.

In summary, a postzygotic reproductive barrier is a mechanism that reduces the viability or reproductive capacity of hybrid offspring. Hybrid zygote abnormality is a type of postzygotic barrier in which hybrid zygotes fail to mature normally.Hybrid infertility is a type of postzygotic barrier in which hybrids are incapable of producing offspring.Low hybrid viability is a type of postzygotic barrier in which the viability of hybrid offspring is lower than offspring in either population.ostzygotic reproductive barriers occur after the zygote has formed, meaning they either reduce the viability (which basically means the ability to avoid dying) or the reproductive capacity of the hybrid offspring.
