What is a Single Embryo Transfer (SET)?
When you’re going through an IVF cycle, you’re faced with many decisions that can feel overwhelming. One of the most crucial choices you’ll need to make is how many embryos to transfer.
What is a Single Embryo Transfer (SET)?
While it might seem logical to transfer more than one embryo to increase your chances of pregnancy, there are many reasons clinics typically transfer one embryo, and many reasons to consider a Single Embryo Transfer (SET) if given the choice.
Understanding what SET is, the benefits it offers, and the statistics behind it can help you make an informed decision that aligns with your personal and medical circumstances.
What is a Single Embryo Transfer (SET)?
A Single Embryo Transfer (SET) is a procedure where only one embryo is selected and transferred into the uterus during an IVF cycle. The goal of SET is to achieve a healthy pregnancy while minimizing the risks associated with multiple births, which can occur when more than one embryo is transferred.
Benefits of a Single Embryo Transfer
1. Reduced Risk of Multiple Pregnancies
One of the most significant benefits of SET is the reduced risk of multiple pregnancies, such as twins or triplets. While multiple pregnancies may sound like a blessing, they come with increased risks for both the mother and the babies, including preterm birth, low birth weight, and complications during pregnancy and delivery. SET significantly lowers the likelihood of these risks by aiming for a singleton pregnancy.
2. Increased Safety for Mother and Baby
By opting for SET, you are prioritizing the health and safety of both yourself and your future baby. Singleton pregnancies generally have fewer complications compared to multiple pregnancies. This can lead to a smoother pregnancy journey, a more straightforward delivery, and a healthier start for your baby.
3. Comparable Success Rates
Advancements in fertility treatments have led to higher success rates with SET, particularly when using high-quality embryos. Studies have shown that SET can achieve pregnancy rates similar to those of transferring multiple embryos, especially in younger women or when using embryos that have undergone genetic screening. This means you can still achieve your dream of a successful pregnancy without increasing the risks associated with multiple embryos.
Statistics Surrounding Single Embryo Transfer
The trend towards SET has been growing as fertility clinics and patients alike recognize the benefits. Here are some key statistics:
Success Rates: According to the Society for Assisted Reproductive Technology (SART), SET has comparable success rates to double embryo transfer (DET) in certain patient populations, particularly when high-quality embryos are used. For women under 35, the live birth rate for SET is often similar to that of DET, with a significantly lower risk of multiples.
Reduction in Multiple Pregnancies: A study published in the New England Journal of Medicine found that SET reduces the risk of twins from 29% in DET cases to less than 2% in SET cases. This drastic reduction highlights the safety advantage of SET for both mother and baby.
Increasing Popularity: In recent years, the use of SET has increased, particularly in countries where regulations or guidelines encourage the practice. In the United States, SET rates have risen as more clinics adopt policies that favor SET, especially in younger patients and those with a good prognosis.
A Single Embryo Transfer (SET) offers a safer, equally effective, and ethically sound approach to achieving a successful pregnancy through IVF. By reducing the risk of multiple pregnancies, SET can provide a smoother, healthier journey for both mother and baby. If you’re undergoing an IVF cycle, discussing SET with your fertility specialist can help you determine if it’s the right choice for your unique circumstances. Remember, every journey is different, and making informed decisions is key to navigating the path to parenthood.
