We have seen that the deliberate restraint of conception has become a part of our civilized morality, and that the practice and theory of facultative abortion has gained a footing among us. There remains a third and yet more radical method of controlling procreation, the method of preventing the possibility of procreation altogether by the performance of castration or other slighter operation having a like inhibitory effect on reproduction. The other two methods only effect a single act of union or its results, but castration affects all subsequent acts of sexual union and usually destroys the procreative power permanently.
Castration for various social and other purposes is an ancient and widespread practice, carried out on men and on animals. There has, however, been on the whole a certain prejudice against it when applied to men. Many peoples have attached a very sacred value to the integrity of the sexual organs. Among some primitive peoples the removal of these organs has been regarded as a peculiarly ferocious insult, only to be carried out in moments of great excitement, as after a battle. Medicine has been opposed to any interference with the sexual organs. The oath taken by the Greek physicians appears to prohibit castration: “I will not cut."[446] In modern times a great change has taken place, the castration of both men and women is commonly performed in diseased conditions; the same operation is sometimes advocated and occasionally performed in the hope that it may remove strong and abnormal sexual impulses. And during recent years castration has been invoked in the cause of negative eugenics, to a greater extent, indeed, on account of its more radical character, than either the prevention of conception or abortion.
