What is Preimplantation Genetic Diagnosis (PGD) for Aneuploidy?
Preimplantation Genetic Diagnosis (PGD) for aneuploidy is a specific type of PGD used with IVF to identify embryos with an abnormal number of chromosomes, a condition called ‘aneuploidy’. One blastomere of each embryo is evaluated for aneuploidy. This testing allows IVF physicians to transfer to the mother’s uterus those embryos with no detectable chromosome abnormalities. This may increase the chance that a couple will become pregnant during a particular cycle. It may also decrease the chance for miscarriage during the pregnancy and reduce the chance for the couple to have a liveborn baby with a chromosome abnormality such as Down syndrome.
