The frequent obstinacy of this distressing condition under every variety of non-electrical treatment, is the cause of the frequency with which cases present themselves to the specialist. Unfortunately however but few of the referred cases are of recent origin. In almost all instances they have gone through a vast amount of medication and other treatment, and finally, either through their attending physicians or of their own accord, they come as a _dernier ressort_ to seek relief from electrical treatment. I have already (p. 47) spoken of the comparative merits in this disease of local and general electrization. A few years ago I was ignorant of the good effects of the baths in male impotency. I came to test and employ them here from two causes. In the first place, patients were sent me specially for electro-balneological treatment, ordered by their physicians; and, second, I began, when I became familiarized with the effects of the baths, to have recourse to them in cases where with local electrical and other treatment I had been unable to accomplish anything. My average results, without becoming uniformly successful, became so very much better, that after a brief but abundant experience with this treatment, I have come to consider it the most important we possess in this affection; one that will frequently succeed when everything else, including local electrization, has failed, and which, in cases where no incurable organic changes underlie the affection, will, if properly persisted in, either cure or improve to a great extent a large majority of the cases. I have even seen instances where, the sexual power having receded as the legitimate result of advancing age, it returned almost or quite perfectly and with seeming permanency under the influence of the baths. In the class of cases—and they are quite numerous—in which impotency (loss of the power of erection) occurs as a purely nervous symptom in comparatively young men; where its cause is sometimes purely imaginative, at others the result of early excesses, the baths are attended with the most gratifying average results. Where the cause is purely psychical, a very few baths are sometimes sufficient to dispel the morbid phenomena. Where masturbation or excessive venery are at the bottom of the trouble, there is always a probability of more or less organic change in the lower portion of the spinal cord, and frequently also a secondary enfeeblement of the digestive functions, which render requisite a long and steadily continued use of the baths. Patients whose sexual power was intact, who took the baths for other purposes, have time and again called my attention to their aphrodisiac effects.
