Preimplantation Genetic Screening of Chromosomes (PGT-A)

It permits selecting only embryos with the right number of chromosomes to be implanted, by extension leading to the birth of a healthy baby.

Preimplantation genetic testing for aneuploidy (PGT-A), also known as preimplantation genetic screening (PGS), is a method that identifies the chromosomal condition of embryos created during IVF, by examining all 23 pairs of human chromosomes. It permits selecting only embryos with the right number of chromosomes to be implanted, by extension leading to the birth of a healthy baby. PGT-A uses the latest next-generation sequencing (NGS) technology to identify those embryos free from chromosome abnormalities, increasing the likelihood of pregnancy per transfer, reducing the risk of miscarriage and allowing single embryo transfer with increased success rates.
