The sensuality attributed to the cryptorchides has been explained by the greater degree of heat experienced in the testicles, when they remain in the abdomen. Be this as it may, the excitement of these organs probably exalts the sense of venery. When the state of excitement is very marked, they swell and become more sensible: these symptoms however are much more marked in animals during the period of rutting, than in our species. Accidental irritations of the testicles have sometimes also caused an unusual excitement of the sense of venery. Moreau attended for a long time a man advanced in age, who consulted him particularly for pollutions attended with amatory dreams. These symptoms which were very distressing constantly occurred, whenever the fibrous membrane of the testicles was affected with chronic rheumatism. From our remarks, we can conceive that extirpation of the testicles would be a powerful remedy, in fact the most efficient of all remedies, to quell lascivious desires, and to put an end to venereal excesses. Hence individuals have been known to sacrifice these organs, and thus to rid them«elves of a salacity which rendered them unhappy. Baldassar relates the history of a man on whom he tried every remedy, and finally found nothing better than fasting and prayers. “Not recovering under these remedies,” says this author, “he wished the operation of castration to be performed, but I thought it inexpedient. The patient however pressed me very earnestly, and sought to win over to his views by presents those who opposed his wishes. He even promised me an ambling poney of remarkable beauty, if I would consent to perform it.” Reduced to despair some individuals have even castrated themselves. Origen, it is well known, mutilated himself, in order to extinguish the warmth of his temperament. This operation has been performed by surgeons and with happy results. A surgeon of Bernstadt was less fortunate: he removed the testes of a man 73 years old, in consequence of the unusual desires he experienced. The operation was not attended with the expected result. (Sprengel, _Hist. de la med._, _vol. ix_.) Hence this remedy is not infallible. We will add that it is far from being without danger, particularly in those individuals who are already exhausted by excesses. Farther, the operation is not confined, as in amputation of the clitoris, to the extinction of the venereal sense: it takes away the procreating power, and causes that moral and physical deterioration which is seen in eunuchs, even when they have lost their testicles after puberty. These therefore are reasons why this operation should not be performed; an operation which is disapproved of by most authors. We will except however Simon, who advises as a last resource in those affected with onanism to press upon or tie the vas deferens or the spermatic artery; for it is better, said he, that the patient should live a eunuch, than that he should inevitably perish.
