[Ethical aspects of preimplantation genetic diagnosis (PGD)]. / Les aspects éthiques du diagnostic pré-implantatoire (DPI).

ABSTRACT

The controversy surrounding PGD has not abated in recent times. This is especially the case for PGD-based tissue typing, which is used to select a future child who could serve as a stem cell donor for an older sick sibling. We examine three types of ethical argument cited against PGD in general, and specifically against tissue-typing PGD. These arguments focus on the moral status of the early embryo, the eugenics issue, and the charge that the future child is being exploited. We conclude that none of these three arguments is unassailable, and that it is the reproductive freedom of couples considering PGD that should prevail.
