Term used to describe the surgical operation by which a human being is directly rendered incapable of reproduction. It is advocated as a eugenic nleasure to prevent the increase of the feebleminded. Sterilization is a debasement of human dignity and an encroachment on personal liberty, but may be imposed by a state when three conditions are verified: (1) that it is established that feeblemindedness is usually inherited; (2) that the number of mental defectives creates a serious burden or danger to the community; and (3) that the state is without other means of protecting itself. None of these conditions is verified at present. Moreover, serious evils would follow the introduction of sterilization, namely, the unnecessary use of the operation, increased sexual promiscuity, and venereal disease.
