Gamete Intrafallopian Transfer (GIFT) is a type of assisted reproductive technology that involves the transfer of eggs and sperm into the fallopian tubes in order to achieve pregnancy. While GIFT has helped many couples struggling with infertility to conceive, it also carries the potential risk of multiple pregnancies. In this blog post, we will dive into the details of GIFT and explore the various risks associated with multiple pregnancies.
Understanding GIFT Procedure
GIFT was first introduced in the 1980s as an alternative to in vitro fertilization (IVF). Unlike IVF, where fertilization of eggs and sperm takes place in a laboratory, GIFT involves the transfer of both the eggs and sperm directly into the woman’s fallopian tubes. This procedure is typically recommended for couples who have unexplained infertility or have had difficulty conceiving through other fertility treatments.
GIFT is a surgical procedure that requires both the female and male partner to undergo separate procedures. The woman will undergo an egg retrieval procedure, where eggs are removed from her ovaries using a needle. The retrieved eggs are then mixed with sperm from her partner or a donor and immediately transferred into her fallopian tubes using a catheter.
Risks of Multiple Pregnancies with GIFT
While GIFT has a success rate of around 25-30%, it also carries a higher risk of multiple pregnancies compared to other fertility treatments. Multiple pregnancies occur when more than one embryo implants in the uterus, resulting in twins, triplets, or even more.
The main reason for the increased risk of multiple pregnancies with GIFT is the transfer of multiple embryos into the fallopian tubes. In IVF, the number of embryos transferred into the uterus can be controlled, but in GIFT, the eggs and sperm are mixed together, making it difficult to determine the exact number of embryos being transferred.
Risks for Mother and Babies
Gamete Intrafallopian Transfer and Multiple Pregnancies: Understanding the Risks
Multiple pregnancies can pose various risks for both the mother and the babies. The mother may experience complications such as gestational diabetes, high blood pressure, and preterm labor. She may also have to undergo a cesarean section delivery, which carries its own set of risks.
For the babies, the main risk is being born premature, which can lead to various health problems such as respiratory issues, developmental delays, and low birth weight. Twins born from GIFT are also at a higher risk of being conjoined, a rare condition where two babies are physically connected.
Reducing the Risk of Multiple Pregnancies
To reduce the risk of multiple pregnancies with GIFT, doctors usually recommend transferring only two embryos into the fallopian tubes. However, in some cases, more than two embryos may be transferred if the woman is older or has had previous unsuccessful fertility treatments.
Another way to reduce the risk of multiple pregnancies is by using pre-implantation genetic testing. This involves screening the embryos for genetic abnormalities before transferring them into the fallopian tubes. This way, only the healthiest embryos are selected for transfer, reducing the chances of multiple pregnancies.
Conclusion
While GIFT has helped many couples to achieve their dream of parenthood, it also comes with the potential risk of multiple pregnancies. It is essential for couples considering GIFT to understand these risks and discuss them with their doctor. By carefully monitoring the number of embryos transferred and using advanced technologies such as pre-implantation genetic testing, the risks of multiple pregnancies can be reduced.
In summary, GIFT is a type of assisted reproductive technology that involves the transfer of eggs and sperm into the fallopian tubes to achieve pregnancy. It carries the potential risk of multiple pregnancies, which can have various implications for both the mother and the babies. However, by carefully monitoring the number of embryos transferred and using advanced technologies, the risks of multiple pregnancies can be reduced.
