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

The risk for a pregnancy with aneuploidy (too many or too few chromosomes, such as Down syndrome) increases with maternal age. Following a chromosomally abnormal pregnancy, the risk for a similar problem to occur again in any subsequent pregnancy is elevated regardless of maternal age. For some couples at an elevated risk, it may be difficult to consider conceiving a future pregnancy. PGD for aneuploidy minimizes the likelihood of a chromosome abnormality in a future pregnancy and increases the chance of achieving an ongoing successful pregnancy.
