Zygote intrafallopian transfer or ZIFT is a reproductive procedure that is very similar to in vitro fertilization procedure (IVF) and embryo transfer.
The only difference is that in ZIFT, the fertilized egg is transferred into the fallopian tube instead of uterus.
This procedure is also called as tubal embryo transfer because the fertilized egg is directly transferred into the fallopian tubes.
The only necessary thing to undergo this procedure is you should have healthy fallopian tubes to work Zygote intrafallopian transfer (ZIFT) successfully.
Procedure of zygote intrafallopian transfer:
- During this procedure, your ovaries are first stimulated by using medications in order to boost the chance of producing several eggs.
- After this, the produced eggs are collected by using the aspiration procedure.
- Then the collected eggs are fertilized in the laboratory similar to the procedure in IVF.
- The fertilized eggs now are transferred by using laparoscopic procedure. In this procedure, the catheter is positioned deeply into the fallopian tube and then the fertilized eggs are inserted.
- The last step in ZIFT is to observe for the early symptoms of pregnancy. Your fertility practitioner uses blood test in order to confirm your pregnancy.
Zygote intrafallopian transfer is beneficial for people who have:
- Tubal blockages
- An anatomic difficulty with the uterus like severe intrauterine adhesions
- Major damages in the fallopian tubes
- Sperms that are not able to penetrate into the eggs
Most of the practitioners recommend this type of treatment as a great option for infertility problems. Generally, this procedure is recommended for couples who are not able to conceive after trying for at least one year and who do not show significant results in 5-6 cycles of ovarian stimulation by using intrauterine insemination.
Is zygote intrafallopian transfer similar to in vitro fertilization?
- Both these procedures are effective for women suffering with severe infertility problems like damaged fallopian tubes.
- Both these procedures consist of embryo culture.
- Both the procedures provide the practitioner with an opportunity to choose only the best quality embryos for transferring.
- The only difference between ZIFT and IVF is, in ZIFT, the fertilized embryo is placed into the fallopian tube and in IVF, the fertilized embryo is placed into the uterus.
Success rate of ZIFT:
On average, 36% of the women can become pregnant who undergoes ZIFT, whereas 29% of the women can have live births.
In this procedure, several eggs are placed in the fallopian tubes, so there is high chance for multiple pregnancies with twins, triplets or more. Also, there is high risk of ectopic pregnancy with this procedure.
