Preimplantation genetic diagnostics is a method which allows to uncover some genetic abnormalities in the genetic embryo structure before their transfer into uterus.
Changes in chromosome count, their structure or some types of hereditary diseases are being tested. The PGD is possible to use only in the relation with IVF cycle – after 72 hours of its development, 1-2 cells are taken from the embryo (blastomeres) which don’t have any specialization yet and the embryo doesn’t miss them. These cells are subjected to genetic testing. Clinical studies doesn’t prove negative influence of further embryo development.
This method improves the chance of successful pregnancy by excluding proven defected embryos and by using embryos genetically healthy in evaluated parameters.
Embryos without genetic disorders are transferred into woman’s uterus.
