[Ethical aspects]

The relation is considered between ethical choices, morals and deontology in plastic surgery of the male external genitals. Ethics dictates the behavioural model applied by an individual or group in their actions. Professional ethics--deontology--is the collection of duties governing the exercise of a certain profession. Morals are the set of rules governing an individual's life in society. Ethics, deontology and morals do not always convey the same message, since environmental, racial and religious situations, custom, and even fashion can influence a patient's demands, reflecting his desire to improve his quality of life, even only from the purely hedonistic viewpoint, and the specialist's attitude. Surgeons are increasingly tending to bend to these demands or--much worse--even encourage and foster them, with a view to financial considerations. The attitude and ethical choices available are examined in relation to surgery to lengthen or enlarge the penis.
