PGS Testing in IVF: Ensuring Chromosomal Normalcy Before Implantation
Preimplantation Genetic Screening (PGS), now commonly referred to as PGT-A, is an advanced genetic test performed during an IVF cycle to evaluate embryos for chromosomal normalcy before implantation. Human embryos should ideally have 46 chromosomes, but abnormalities such as missing or extra chromosomes can reduce implantation rates, cause miscarriages, or lead to genetic conditions. PGS testing helps identify embryos with the correct chromosomal number, improving the chances of a healthy pregnancy.
