Zygote Intrafallopian Transfer (ZIFT) is a reproductive technology similar to in vitro fertilization (IVF), with a key distinction: the fertilized egg, or zygote, is placed directly into the fallopian tubes rather than the uterus. This method is particularly beneficial for couples facing certain infertility challenges, as it allows the zygote to implant naturally in the uterine lining.
How is ZIFT Performed?
The ZIFT procedure typically involves several steps:
- Ovarian Stimulation: The woman receives hormonal medications to stimulate her ovaries to produce multiple eggs.
- Egg Retrieval: A minimally invasive procedure is conducted to extract the mature eggs from the ovaries.
- Fertilization: The retrieved eggs are fertilized with sperm in a laboratory setting. Unlike conventional IVF, where embryos are usually transferred after a few days, ZIFT transfers the fertilized zygotes back into the fallopian tubes within 24 hours.
- Laparoscopic Transfer: Using a laparoscope, a thin tube with a camera, a healthcare provider carefully places the zygotes into the fallopian tubes through a catheter.
- Monitoring for Pregnancy: After the transfer, the woman will be monitored for early pregnancy symptoms. A blood test is typically used to confirm if implantation has occurred.
Who is a Candidate for ZIFT?
ZIFT may be recommended for couples dealing with infertility issues, excluding conditions such as:
- Blocked fallopian tubes
- Severe uterine abnormalities, like significant intrauterine adhesions
- Male factors where sperm cannot penetrate the egg
This option is often selected by couples who have been unable to conceive after a year of trying or after multiple failed cycles of intrauterine insemination (IUI).
ZIFT vs. IVF: Similarities and Differences
Both ZIFT and IVF are viable treatments for infertility, especially for women with more severe complications, such as damaged fallopian tubes. Here are some key points of comparison:
- Both techniques involve embryo cultivation.
- ZIFT transfers the fertilized zygote into the fallopian tubes, while IVF typically places the embryo into the uterus.
- The ZIFT process requires an additional surgical step (laparoscopy) compared to standard IVF procedures.
