[Ethical aspects of preimplantation diagnostics]

Pre-implantation Genetic Diagnosis (PGD) enables to genetic examination of an embryo springed up in vitro before his transfer to mother's womb. The ethical valuation of this affair is different. Fundamentally, ethic-medical debate takes the interest in practical advantages and in unwholesome of this method. But ethic-theological discussion indicates' that PGD is the breaking of regulations concerning in the protection of the embryo. According to theological point of view, PGD is also the violation of conviction about human dignity and his rights to life from the conceiving. Therefore human embryo from his beginning should be protected against the instrumentalization or the extermination. Moreover the selection of embryos supposes a repartition between valuable and worthless life. Totally, PGD is contradictory to the teaching of Church. It produces greater complications than solutions of problems.
