How can PGD for aneuploidy help?
PGD allows the testing of each embryo separately so that those with 46 chromosomes are transferred to the mother’s uterus. Transferring those embryos with the correct number of chromosomes 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. There are several technologies currently used to perform PGD for aneuploidy screening. GSN’s Parental Support is the newest and most advanced technology and enables testing of all 24 chromosomes for aneuploidy with results returned in time for transfer on Day 5 with no embryo freezing required. The other commonly used technologies, both with their own benefits and limitations, are FISH and CGH.
