Zygote Intrafallopian Transfer -ZIFT- in San Antonio Texas
ZIFT, or zygote intrafallopian transfer, refers to the implanting of a fertilized egg in a healthy fallopian tube. This procedure is rarely performed, as success rates from IVF have improved significantly.
ZIFT begins similarly to the IVF process. First, fertility medications are used to stimulate the ovaries to produce multiple eggs, which are then collected. Afterwards, the eggs are fertilized in an IVF laboratory. At this point, the similarity to the IVF procedure ends. Through the ZIFT procedure, the fertilized eggs are laparoscopically transferred to the fallopian tubes and travel to the uterus for implantation naturally. A pregnancy test will be done to confirm implantation.
Candidates for ZIFT
Zygote intrafallopian transfer is not a viable option if the fallopian tubes are damaged or blocked. ZIFT may be performed with only one healthy fallopian tube.
Benefits of ZIFT
Although ZIFT may be more expensive and more invasive than standard IVF cycles, it may have a benefit. In standard IVF, the fertilized eggs are kept in the laboratory for 3-5 days prior to being transferred to the uterus. In ZIFT, however, the fertilized egg is transferred to the fallopian tube 24 hours after egg retrieval, immediately after fertilization is confirmed.
The reduced time the fertilized egg spends outside the body decreases the amount of stress on the embryo, increasing embryo quality. Higher embryo quality improves the likelihood of implantation. This was more significant in the past when laboratory conditions were less optimal.
