Why Is Single Embryo Transfer Recommended in IVF-PGT?

In the context of IVF-PGT (In Vitro Fertilization with Preimplantation Genetic Testing), it is common practice to transfer only a single embryo rather than multiple ones. Several reasons underlie this approach, some of which are associated with the quality of embryos and the success rates of implantation.

Firstly, a pivotal step in IVF-PGT is PGT, or Preimplantation Genetic Testing, which examines the chromosomes of embryos. After undergoing PGT testing, selected embryos typically possess normal chromosomes, significantly increasing the chances of successful implantation, often achieving a success rate of 70% or more. This means that each embryo selected for transfer has a high potential for a successful pregnancy.

Another reason relates to embryo splitting. Although less common, there is approximately a 6% chance that a single embryo will split into two embryos following a successful transfer. In such cases, if multiple embryos are simultaneously transplanted, it may result in a multiple pregnancy. Multiple pregnancies carry a higher risk of various complications, including high blood pressure, diabetes, excessive amniotic fluid, placental abruption, disseminated intravascular coagulation, postpartum hemorrhage, and more. To avoid these risks, medical professionals generally recommend single embryo transfer.

Moreover, single embryo pregnancies are more in line with physiological norms, as a woman's uterus typically prepares for just one fetus. When multiple embryos develop in the uterus, they may compete with each other for nutrients, leading to potential health issues such as jaundice, anemia, and compromised immune function. Therefore, single embryo pregnancies are conducive to ensuring the health and proper development of embryos.

In summary, many reputable clinics recommend single embryo transfers. This approach not only enhances the success rates of implantation but also lowers the risks associated with multiple pregnancies, ensuring the well-being of both mother and child.
