PGD is recommended for couples who are known carriers of a single gene disorder (genetic disease) like Hemophilia or Cystic Fibrosis. PGD is performed after a woman’s eggs have been retrieved and fertilized by her partner’s sperm, but before the embryos have been transferred back into her uterus.
When the fertilized egg has reached blastocyst stage, 5-7 cells are gently removed from each embryo using a microsurgery technique. The DNA from the removed cells is then analyzed using a specifically designed probe that is created to test for a specific gene disorder. This technique allows us to detect healthy from non-healthy embryos. Only healthy embryos are transferred which allows pregnancy to safely begin with ease of mind.
