Preimplantation Genetic Diagnosis (PGD) is a screening process that can be used before embryo implantation, it can reduce the chance of passing genetic disease to the baby by finding out chromosome abnormalities early.
Doctors will extract a couple of cells from the embryo to undergo observation and testing. Through this process, doctors can find out common chromosome abnormalities.
Finally, the healthy embryo will be implanted into the mother’s uterus.
