PGT-A, or Preimplantation Genetic Testing for Aneuploidy, is a procedure used during in vitro fertilization (IVF) to assess the genetic health of embryos. This testing helps identify embryos with the correct number of chromosomes, which is crucial for successful implantation and healthy pregnancy outcomes. By analyzing the genetic material of embryos before they are implanted in the uterus, PGT-A can increase the chances of a successful pregnancy and reduce the risk of miscarriage. This technique is particularly beneficial for individuals or couples with a history of genetic disorders or advanced maternal age.
