Question

Which of the following is the correct difference between GIFT and ZIFT?

• A. In GIFT, male gamete is transferred into female body and in ZIFT, female gamete is placed inside the uterus.
• B. In GIFT, egg and sperm are placed inside the fallopian tube and in ZIFT fertilised zygote is placed in the fallopian tube.
• C. In GIFT, fertilisation takes place outside the body and in ZIFT, fertilisation takes place inside the body.
• D. None of the above

Answer 1

The correct option is B In GIFT, egg and sperm are placed inside the fallopian tube and in ZIFT fertilised zygote is placed in the fallopian tube.

GIFT (gamete intrafallopian transfer) and ZIFT (zygote intrafallopian transfer) are modified versions of in vitro fertilisation. Like IVF, these procedures involve retrieving an egg from a woman and re-implanting it after manipulation. Unlike IVF, the timing between mixing the sperm and eggs and the transfer is faster. In GIFT, the sperm and eggs are mixed together and immediately inserted. On the other hand, with ZIFT, the fertilised eggs (zygotes) are inserted within 24 hours of the mixing.
