Abstract
In 1994, France passed bioethics laws regulating assisted reproductive technologies, organ donations and prenatal diagnosis. These laws were based upon a few principles considered as fundamental: the anonymity and gratuity of all donations concerning the elements of the human body, free and informed consent, and the interdiction of all commercial transactions on the human body. These laws have been the object of heated debates which continue to this day. On the basis on a few clinical ethics studies conducted by the Center for clinical ethics at the Cochin Hospital in Paris, the articles presented in this special issues explore several aspects of the bioethics debate, and relate it to the more general question of the complex relationship between norms, practices and values
