 Also known as "the third generation of IVF", it refers to the genetic testing technology that carries out genetic mutation or chromosome detection on the embryo before implantation in the process of assisted reproduction, and selects the normal embryo to be implanted into the uterine cavity, so as to reduce the risk of family hereditary diseases, chromosome abnormalities and repeated abortion. This technique mainly includes preimplantation chromosomal aneuploidy detection (PGT-A), preimplantation chromosomal structural abnormality detection (PGT-SR) and preimplantation monogenic genetic disease detection (PGT-M).
