Zygote Intra-Fallopian Transfer (ZIFT)

Zygote Intra-Fallopian Transfer (ZIFT)

ZIFT is an assisted reproductive procedure similar to in vitro fertilization and embryo transfer, the difference being that the fertilized embryo is transferred into the fallopian tube instead of the uterus. Because the fertilized egg is transferred directly into the tubes, the procedure is also referred to as tubal embryo transfer (TET). This procedure can be more successful than gamete intrafallopian transfer (GIFT) because your physician has a greater chance of insuring that the egg is fertilized. The woman must have healthy tubes for ZIFT to work.

The ZIFT procedure involves the following steps:

A woman's ovaries are stimulated with medications to increase the probability of producing multiple eggs. Eggs are then collected through an aspiration procedure. Those eggs are fertilized in a laboratory in a procedure identical to IVF, with the exception of the time frame. During the ZIFT procedure, fertilized eggs are transferred within 24 hours, versus 3-5 days as used in a regular IVF cycle. The fertilized eggs are then transferred through a laparoscopic procedure where a catheter is placed deep in the fallopian tube and the fertilized eggs injected. The final step is to watch for early pregnancy symptoms. The fertility specialist will probably use a blood test to determine if pregnancy has occurred.
