Kloneren: toepassingen bij de mens. II. Ethische verkenning

- Reproductive cloning in adults/children evokes unfavourable reactions.

- Direct objections are that cloning is unnatural, that it affects human dignity and violates the individual's right to genetic uniqueness.

- Consequential objections concern unjustified health risks for the progeny, unjustified psychosocial risks for the clone child and the risk of cloning for eugenetic purposes. There is consensus that reproductive cloning of existing persons is unjustifiable as yet because of the health risks for the offspring.

- Reproductive cloning of embryos is possible by means of nucleus transplantation and of embryo splitting.

- The ethical analysis of reproductive cloning of embryos depends on the purposes and applications.

- At least some of the moral objections against cloning of adults/children are not or not completely applicable to reproductive cloning of embryos.

- Conditions to be put to reproductive cloning of embryos are efficacy, safety and, at least for the time being, avoidance of asynchrony in transferring identical embryos. The ethical aspects of its application in the context of genetical reproductive techniques must be evaluated separately.

- Therapeutic cloning may be acceptable if alternatives are lacking.
