The problem of human enhancement technologies (HET) is linked to Transhumanism, a  trend which advocates the improvement of human beings and the possibility of taking control of ever larger areas of human activity. Using enhancers might appear desirable, but permitting (or perhaps making obligatory) the use of enhancers by certain professional groups raises important issues. Medical professionals in particular bear technical, moral and legal responsibilities for the lives and health of other people, and questions relating to the involvement of enhancers on the part of practitioners touch upon a number of concerns. Among them are agreement on the definition of 'enhancement and 'enhancers; the motivations for which a physician has decided to use HET, and not least, the consequences for safeguarding  patient rights. These issues must be decided under the applicable standards and regimes of civil, criminal or professional liability. These regimes do not at present refer directly to the responsibility of an  'enhanced' physician. They propose, however a 'cautious' approach to the problems of the use of enhancers,  indicating that use of  technologies (that are not already specifically prohibited)  might be  permitted where there is no exposure to the possibility of harm or any threat to human life or health. The de lege ferenda  proposal is to introduce legislative changes which would specifically and unequivocally refer to the situations under consideration.
