Preimplantation genetic testing (PGT) involves testing
pre-implantation embryos for chromosomal numerical abnormalities
(aneuploidy). Preimplantation genetic diagnosis (PGD) involves genetic
testing of embryos for specific genetic conditions. The objective of
both PGT and PGD is to identify embryos that are aneuploid or
genetically defective so as to selectively transfer the most
“competent” so as to improve embryo implantation potential, reduce
the risk o…
