For couples eager to become parents, twins are often an appealing option. Some believe that having two babies at once is ideal, especially if they are a boy and a girl. However, many are not aware that multiple pregnancies are medically referred to as "the obstetrician's nightmare," as they often come with a series of complex risks that could threaten the health of both the mother and the babies. Therefore, in the U.S., doctors typically recommend single embryo transfers for good reason.

 

With advancements in assisted reproductive technology, the success rates of IVF have gradually increased, making it unnecessary to transfer multiple embryos to enhance the chances of pregnancy. Although the pregnancy rate for transferring a single embryo may be slightly lower, from a safety and health perspective, single embryo transfer significantly reduces the incidence of multiple pregnancies, as well as the risks of preterm birth, low birth weight, and cesarean delivery. Single pregnancies also increase the likelihood of natural delivery and shorten the interval before the next pregnancy.

 

When recommending single embryo transfers, doctors consider the dual safety of both the mother and the fetus. The risks associated with multiple pregnancies are far greater than those of single pregnancies, including significantly higher rates of miscarriage, anemia, gestational hypertension, and diabetes. Additionally, the risk of complications such as polyhydramnios, premature rupture of membranes, and placental abruption also greatly increases, making the entire pregnancy process more complex.

 

Modern IVF technology, especially the third-generation IVF-PGT technology in the U.S., ensures that only quality embryos are transferred through pre-implantation genetic and chromosomal testing. This not only improves success rates but also reduces the risk of miscarriage and fetal stoppage, providing safer assurances for both the mother and the fetus. Therefore, choosing a single embryo transfer is aimed at minimizing risks during the conception process, ensuring the health of the baby and the safety of the mother.
