Many couples struggle with infertility worldwide. Although in vitro fertilization (IVF) is an effective assisted reproductive technology (ART) method for couples struggling with infertility, not all IVF cycles result in a successful pregnancy. A common cause of IVF failure is chromosomally abnormal (aneuploid) embryos. Embryo chromosome screening methods, such as preimplantation genetic screening (PGS) can be applied to the IVF process. This type of screening can be used to aid in the selection of embryos with a normal number of chromosomes (euploid) for transfer, to help improve outcomes.
