"Senile Sexuality.-As with childhood, old age is a period I which the reproductive functions are quiescent unless unnaturally stimulated. Sexual life begins with puberty, and, in the female, ends at about the age of forty-five years, the period known as the “menopause”, or “turn of life”. At this period, according to the plainest indications of nature, all functional activity should cease. If this law is disregarded, disease, premature decay, possibly local degenerations, will be sure to result. Nature cannot be abused with impunity. The generative power of the male is retained somewhat longer than that of the female, and by stimulation may be indulged at quite an advanced age, but only at the expense of shortening life, and running the risk of sudden death. Says Parise, “One of the most important pieces of information which a man in years can attain is “to learn to become old betimes,’ if he wishes to attain old age. Cicero, we are told, was asked if he still indulged in the pleasures of love. ‘Heaven forbid,’ replied he, ‘I have forsworn it as I would a savage and a furious master.’” Some learned physicians place the proper limit of man’s functional activity at fifty years, if he would not render himself guilty of shortening his days by sensuality. Other reasons for this course will appear hereafter. When the passions have been indulged, and their diminishing vigor stimulated, a horrid disease, “satyriasis”, not infrequently seizes upon the imprudent individual, and drives him to the perpetration of the most loathsome crimes and excesses. Passions cultivated and encouraged by gratification through life will thus sometimes assert a total supremacy in old age."
