Question

Difference between ZIFT and GIFT

Answer 1

GIFT (gamete intrafallopian transfer) and ZIFT (zygote intrafallopian transfer) are modified versions of in vitro fertilization. Like IVF, these procedures involve retrieving an egg from the 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 fertilized eggs --”zygotes”-- are inserted within 24 hours of the mixing.
What are the advantages to these procedures?
While the success rates are similar to IVF, the processes used in GIFT and ZIFT are closer to natural conception. In ZIFT, the eggs are placed in the fallopian tubes rather than directly in the uterus. With GIFT, fertilization actually takes place in the body rather than in a petri dish.
