Pre-implantation genetic screening (PGS)

Pre-implantation genetic screening (PGS), also known as comprehensive chromosome screening or CCS, is a genetic test designed to examine embryos for chromosomal abnormalities. Embryos are biopsied at the blastocyst stage and all the chromosomes are examined. Embryos with too many or too few chromosomes, a condition called aneuploidy, often result in unsuccessful IVF or early pregnancy loss. By only placing embryos with the correct number of chromosomes (euploid embryos) in the uterus, PGS aims to improve implantation and pregnancy rates in people having IVF. PGS could potentially benefit many people who are planning to do IVF, specifically those of advanced reproductive age or those with a history of recurrent pregnancy loss.
