This article presents an analysis of the ethical considerations raised by preimplantation genetic diagnosis from a Jewish perspective. It weighs the Jewish imperatives to pursue good health against a number of harms that may follow from the expanded use of PGD technology, including increased medical risk to the mother, the destruction of embryos and possible emotional harm to the child born from this procedure. It pays special attention to the potential harms that may befall those in society who do not (...) have access to PGD or who choose not to employ it. (shrink)

The desire to have healthy and happy children is the most basic parental instinct. A parent's moral obligation to care for the child extends before the moment of birth back to the point of conception. In classical Jewish tradition, the Talmud itself offers pregnant women advice on how to improve the well-being of their offspring, such as eating parsley in order to have handsome children, drinking wine in order to bear healthy children, or eating coriander to have especially plump children. (...) We stand on the cusp of a new era today because an explosion of genetic knowledge in recent years has provided us the ability to pursue certain health and wellness advantages even before pregnancy has begun. Technology called preimplantation genetic diagnosis allows parents to screen the DNA of embryos fertilized in vitro and to implant only those embryos that match the parents' desired genetic makeup. This may include selecting only embryos guaranteed not to have a particular genetic disease, only embryos of one particular gender, or eventually even only embryos with a predisposition for certain traits such as height, eye color, or enhanced memory.
