Embryo selection is a process used in assisted reproductive technology, such as in vitro fertilization (IVF), to choose the most viable embryos for implantation. This selection is based on various criteria, including the embryos' appearance, growth rate, and genetic testing results. The goal is to increase the chances of a successful pregnancy and reduce the risk of genetic disorders. The selection process can involve techniques like preimplantation genetic testing (PGT), which screens embryos for specific genetic conditions. By identifying healthy embryos, clinicians aim to improve outcomes for individuals or couples undergoing fertility treatments, ultimately leading to healthier pregnancies and babies.
