[Preimplantation genetic diagnosis. Ethical, social and legal aspects]

Preimplantation genetic diagnosis (PGD) undertakes an examination of an embryo outside the mother's womb subsequent to artificial insemination in order to identify a potential genetic and chromosomal impairment of that embryo. PGD is not being practiced in the Federal Republic of Germany since it cannot be reconciled with the provisions of the Embryo Protection Law. Objections have been raised against PGD based on ethical, religious and feminist arguments as well as on the grounds of legal framework policy. The essence of those objections relates to the fact that this method relativises the inviolability of the embryo in its early stages. Even human dignity itself is considered in danger. However, those objections have themselves caused demur. A variety of ethical reasons make it appear conceivable to allow PGD under narrowly defined conditions in medically founded cases. PGD can be used to the benefit of the health of both the pregnant mother and the expected children. In case PGD should be permitted, it would have to be within the framework of medical and sociopsychological counselling.
