[Prisoners as subjects of biomedical research]

The medical research with prisoners ever along the History until our age has attacked to physical integrity and prisoners' human rights. We have a perfect evidence about this kind of human rights violation if we have a look sixty years ago to Nazi's concentrations camps. Probably for this reason the international legislations restricts or ban this type of practices. There are, although, some arguments used for it, like the impossibility to decide something inside a context with lack of freedom, improper inducements, coercion and duress. The objective of our work is study if exist any important reason, inside a pure bioethical view, that support the prohibition of using prisoners as subjects in medical research, showing actual fettles of Spanish prisons.
