PGT for Aneuploidy (PGT-A) is applied to detect any chromosomal aneuploidies in the embryos which can affect the chance of a successful embryo implantation, normal pregnancy and livebirth of a healthy baby. Chromosomes are packages of genes within the cells. Extra or missing chromosomes cause chromosomal aneuploidies. These aneuploidies are generated randomly during the embryo development. PGT-A can distinguish euploid from aneuploid embryos and it was formerly known as Preimplantation Genetic Screening (PGS)
Who should undergo PGT-A
Women of advanced age as they have higher chances of chromosomal aneuploidies due to the aging of their eggs
Couples with recurrent miscarriages
Couples with multiple IVF failures
Men with severe oligozoospermia
