Zygote intra fallopian transfer (ZIFT) is an
ovaries, and in vitro fertilised. The resulting zygote is placed into the fallopian tube by the use of laparoscopy. The procedure is a spin-off of the gamete intrafallopian transfer (GIFT) procedure. The pregnancy and implantation rates in ZIFT cycles are 52.3 and 23.2% which were higher than what was observed in IVF cycles which were 17.5 and 9.7%.[1]
Procedure
The average ZIFT cycle takes five weeks-six weeks to complete. First, the female must take a
laparoscope
.
Indications
ZIFT has been used in infertility situations where at least one of the fallopian tubes is normal and other treatments have failed; however, the need for two interventions and the fact that
IVF results are equal or better (as of 2004), leaves few indications for this procedure. Accordingly, the number of ZIFTs performed has been declining.[2]
