What is Preimplantation Genetic Screening (PGS) ?

Preimplantation genetic screening (PGS) for aneuploidy is a powerful genetic test that may be performed on embryos during IVF treatment to screen for numerical chromosomal abnormalities.

PGS is performed on a small embryo biopsy prior to transfer and identifies which embryos are chromosomally normal.

Chromosomally normal embryos are the most likely to develop to term and to be born as a healthy baby. PGS testing helps IVF physicians and patients decide which embryos to transfer.
