Certain cases of impotence in men and of infantilism in women are examples of defects in the internal stimulus. About 3 per cent of men are completely impotent. Some men are partially impotent. All men, of course, reach the point some time after middle age when a diminution in the internal stimulus gradually brings on the complete impotence of old age. Impotence in young men is not extensive enough to justify the emphasis sometimes placed upon it in popular conversation, although it is true that partial impotence does contribute to sexual maladjustment in marriage to a considerable extent, as we shall see later. In fact, one may regard nine-tenths of all that one hears on the subject in popular conversation as nonsense. There is no particular merit in being "potent" or having the "powers of manhood," when almost all men have ample sexual capacity without devoting any effort to the matter. Moreover, potency does not depend upon the size of the penis. If a genuine case of impotence does occur, the advice of a competent physician should be sought to determine whether the difficulty is due to some physiological defect or whether it may be due to some nervous disturbance or inhibition which may yield to treatment by a psychiatrist. Quacks who advertise themselves as specialists in this field or engage in other unethical practices should be avoided. Temporary impotence may be due to fatigue, depression, fear, worry, or sometimes to sexual excess. The obvious treatment here is to remove the cause.
