Over the past three decades, the landscape of infertility treatment has transformed significantly, thanks to advancements in technology that enhance the chances of conception. This evolution is especially evident during the embryo transfer phase of in vitro fertilization (IVF). When a woman opts for IVF, her eggs are harvested and fertilized with either her partner’s or a donor’s sperm. Once these embryos have developed into high-quality specimens—typically around the fifth day—it’s time to decide how many to transfer. This is where the discussion around “Twins: The Fetal Paradox” becomes relevant.
In the early days of IVF, many specialists recommended transferring multiple embryos. “It was like playing the odds,” noted Dr. Alex Winters, a fertility expert. The technology back then wasn’t as refined, so transferring several embryos maximized the chances of a successful pregnancy. However, with modern laboratory techniques, embryologists can now more accurately identify the best embryos to transfer. For patients with a positive prognosis, opting for a single embryo transfer—known as elective single embryo transfer (eSET)—can yield similar success rates as transferring multiple embryos, but without the increased risks associated with multiple pregnancies. At our practice, eSET has become quite popular, with a rate nearly five times greater than the national average.
Common Questions About eSET
What defines a good prognosis patient in IVF?
Good prognosis patients typically include women who have the highest likelihood of success, determined by factors such as age guidelines set by the American Society for Reproductive Medicine (ASRM), those without a history of unsuccessful IVF attempts, or those with high-quality embryos available.
What are the health risks tied to multiple pregnancies?
While many healthy twins and triplets are born, multiple pregnancies can lead to additional risks for both the mother and the babies. These include heightened chances of miscarriage, gestational diabetes, hypertension, and premature delivery, among others. Because of these risks, we encourage good prognosis patients to consider eSET to minimize the likelihood of complications.
How likely am I to conceive with just one embryo?
For patients with a good prognosis, the chances of conception are similar whether one or two high-quality embryos are transferred. In fact, data shows that nearly 80% of pregnant patients in our IVF program achieved singleton pregnancies in 2013, with 66% of women under 38 choosing eSET.
Why do some patients still opt for multiple embryo transfers?
Every patient is unique, and their individual histories and diagnoses influence treatment recommendations. While our ideal is to transfer high-quality embryos, there are cases where a doctor may suggest transferring more than one, especially if the quality isn’t optimal or if previous cycles with a single embryo have failed. Ultimately, the choice between eSET and multiple transfers rests with the patient, though we always advocate for eSET when conditions are favorable.
The Evolution of Insurance and eSET
One significant factor leading patients to prefer multiple transfers is the financial burden of fertility treatments. Many insurance providers either don’t cover the costs or only cover limited cycles. This can lead patients to believe that transferring multiple embryos increases their chances of success in one go. Fortunately, some insurance companies are starting to adapt their policies, covering second transfers if the first eSET doesn’t succeed. “This could become a trend,” Dr. Winters expressed. “It’s beneficial for insurance companies too—IVF costs are lower compared to the long-term complications of premature multiples.”

In summary, the shift towards eSET represents a major stride in infertility care, providing safer options with comparable success rates. With the right information and support, patients can make informed decisions on their journey to parenthood.
