PGDlab : For Physicians : What is PGD : Q & A

All women have a risk to have a pregnancy with a chromosome abnormality. This risk increases as a woman’s age increases. Prenatal diagnosis by chorionic villus sampling (CVS) or amniocentesis to test for chromosome abnormalities, such as Down syndrome, is available. Not all couples want to face decisions during an ongoing pregnancy regarding a chromosome abnormality in the fetus. Couples may instead pursue PGD for aneuploidy screening to optimize the chance of having a healthy pregnancy.
