While there is little truth in the theory of Hippocrates that masturbation causes spinal disease, there is no doubt whatever that neurasthenia is one of its commonest sequela?. Eulenberg records the case of a young girl in which the neurasthenic symptoms are classical. She was twenty-eight years of age, of dark complexion, a fully developed figure, without any trace of anemia or chlorosis, but with an apathetic expression, bluish rings around the eyes, and hypochondriacal and melancholic tendencies. She complained of pressure on the head, "as if her head would burst," giddiness ringing in the ears, photopsia, pain in the back and sacrum, and all the syndromes of spinal adynamia; fatigue on the least exertion, swaying, when standing with the eyes closed, and with the tendon reflexes all exaggerated. After much persuasion she confessed that, when a girl of twelve, she had been led to masturbation by the repeated attempts of a boy of sixteen to seduce her. Eulenberg considered the symptoms she complained of plainly due to long continued masturbation.1
