Question

Briefly describe Zygote Intra Fallopian Transfer (ZIFT) technique practice to help infertile couples.

Hint:

Contrast ZIFT with IUT (Intra Uterine Transfer). ZIFT = Fallopian tube (up to 8 cells). IUT = Uterus (> 8 cells).

Answer 1

Step 1: Understanding the Concept:
ZIFT is a variation of In Vitro Fertilization (IVF) where fertilization happens outside the body in a laboratory.
Step 2: Detailed Explanation:
1. Fertilization: Ova from the wife/donor and sperms from the husband/donor are collected and induced to form a zygote under simulated conditions in the lab.
2. Stage of Transfer: The zygote or early embryo (with up to 8 blastomeres) is then transferred into the fallopian tube of the female.
3. Post-Transfer: The embryo then travels naturally to the uterus for implantation and further development.
Step 3: Final Answer:
ZIFT involves the transfer of an early embryo (up to 8-blastomere stage) directly into the fallopian tube to facilitate natural implantation in infertile couples.
