GIFT amd ZIFT MCQ - Practice Questions with Answers

Gamete Intrafallopian Transfer (GIFT):

• Gamete intra-fallopian transfer involves the transfer of both sperm and unfertilized oocyte into the fallopian tube. 
• This allows the fertilization to naturally occur in vivo. 
• The prerequisite for GIFT procedure is that the woman should have at least one normal fallopian tube.
• Couples who want a natural treatment so that the fertilization and implantation process occurs inside the woman’s body opt for this form of assisted reproductive technology.

Zygote Intrafallopian Transfer (ZIFT):

• This is another form of assisted reproductive technology. ZIFT is similar to IVF and embryo transfer. 
• However, the primary difference is that the embryo transfer after fertilization is done in the fallopian tube in case of ZIFT whereas in the case of IVF the embryo is transferred in the uterus. 
• As the fertilized egg is transferred directly into the tubes, the procedure is also referred to as tubal embryo transfer (TET).
• ZIFT has an advantage over GIFT with male factor infertility.
