Zygote Intrafallopian Transfer (ZIFT)
The ZIFT Procedure
ZIFT is an assisted reproductive procedure similar to in vitro fertilization, but unlike IVF, the fertilized embryo is not transferred into the uterus. Instead, the egg is harvested and fertilized in the laboratory before being transferred directly into the fallopian tube.
The transfer takes place during the zygote phase through a laparoscopic procedure performed under general anesthesia. The body then carries the zygote from the fallopian tube to the uterus for implantation.
ZIFT versus IVF
Today ZIFT is rarely performed and few fertility clinics offer the procedure. Since it requires separate procedures for egg retrieval and zygote placement, patient risk and expense are higher in ZIFT. The procedure also requires a woman have at least one healthy, functional fallopian tube and may not be appropriate for those with certain uterine problems.
Improved IVF techniques and success rates have made in vitro fertilization the treatment of choice in most fertility clinics in the United States. Statistics from The Society for Assisted Reproductive Technologies indicate ZIFT is used in fewer than 1 percent of all assisted reproductive procedures done in this country.
