Preimplantation Genetic Testing for Aneuploidies (PGT-A) is a laboratory technique performed on embryos created through IVF, in which cells biopsied from the blastocyst are screened for chromosomal abnormalities before transfer. It aims to identify euploid (chromosomally normal) embryos for transfer, with the goal of improving implantation rates and reducing the risk of miscarriage.
