Why is it Recommended to Transfer Only One Blastocyst During IVF-PGT Treatment?

During IVF-PGT treatment, doctors often recommend transferring only one blastocyst rather than multiple. To understand this recommendation, we consulted Dr. Nathan Zhang, a national expert in assisted reproduction, PhD from the University of Pennsylvania School of Medicine, and founder of IVF USA. He highlighted several considerations behind this approach, primarily involving blastocyst quality, transfer success rates, and maternal and fetal health.

First, one of the key steps in IVF-PGT is pre-implantation genetic testing (PGT), which screens for chromosomal issues in embryos. Blastocysts selected through PGT usually have a normal chromosomal structure, significantly improving the chances of successful implantation. This means each transferred blastocyst has a high developmental potential, reducing the need to transfer multiple embryos.

Secondly, transferring multiple blastocysts carries the risk of multiple pregnancies. While some families may look forward to twins or more, this actually increases health risks during pregnancy. Multiple pregnancies can lead to complications such as gestational hypertension, gestational diabetes, and preterm birth, which are not only detrimental to the mother but also affect fetal health. Therefore, single embryo transfer better reduces these risks and protects both maternal and fetal safety.

Additionally, the uterus is designed for single pregnancies, and multiple embryos may compete for nutrients and space during development, impacting the health of the embryos. Research indicates that single embryo transfer ensures the embryo receives adequate nutrition and a stable developmental environment, helping to prevent health issues in the newborn.

In summary, transferring a single blastocyst not only improves the success rate of IVF-PGT but also reduces the risk of multiple pregnancies, ensuring maternal and fetal health.
