PGD has been used for medical purposes only to avert life-threatening disease in children. The study of it has progressed to the point where it could be used to create designer babies. PGD is a technique that is used to scan a three-day embryo to see if it carries a particular genetic disease, and if it doesn’t then the embryo is planted into the mother’s womb. PGD has been taken a step a farther and is used to target less-serious disorders or certain characteristics. PGD has steadily expanded its scopes. It can also be used to help a younger brother or sister whose healthy cells can be harvested to treat an older sibling with a serious illness. Dr. Steinberg takes a new approach for screening embryos that involves taking cells from a five day old embryo instead of cells from a three day old embryo to make a more reliable diagnosis of the embryo.
