In-vitro fertilization (IVF) has helped countless couples start a family. One question that often arises during the IVF process is the possibility of having twins. In this blog post, we will explore the factors that influence the likelihood of having twins through IVF.
The Link Between IVF and Twins
IVF has a higher incidence of twin pregnancies compared to natural conception. This is primarily due to the practice of transferring multiple embryos during an IVF cycle to increase the chances of success. When more than one embryo implants and develops, it results in a multiple pregnancy, most commonly twins.
Factors Influencing the Chances of Twins in IVF
1. Number of Embryos Transferred: The more embryos transferred during an IVF cycle, the higher the chances of having twins. However, many clinics now advocate for elective single embryo transfer (eSET) to minimize the risks associated with multiple pregnancies.
2. Age of the Mother: Women under the age of 35 have a higher likelihood of having twins through IVF due to better egg quality and a higher chance of multiple embryos implanting.
3. Quality of Embryos: High-quality embryos have a better chance of implantation and development, increasing the possibility of twins.
4. Assisted Hatching: This laboratory technique, which involves creating a small opening in the embryo's outer layer, may increase the chances of implantation. Assisted hatching slightly increases the risk of identical twins.
Risks and Considerations
While the prospect of having twins may seem exciting, it is essential to understand the potential risks and challenges associated with multiple pregnancies. Twin pregnancies carry a higher risk of complications such as preterm labor, low birth weight, and gestational diabetes. It is crucial to discuss these risks with your fertility specialist and make an informed decision about the number of embryos to transfer.
Conclusion
The chances of having twins through IVF are influenced by several factors, including the number of embryos transferred, the age of the mother, embryo quality, and assisted hatching techniques. While twins may seem like a welcome surprise, it is important to weigh the potential risks and challenges carefully. Your fertility specialist can provide personalized guidance based on your unique circumstances, helping you make the best decision for your family. PGT-A is an effective tool to select single embryos for transfer thus significantly lowering the risk of twins and associated complications.
