1908) Nyström vigorously sums up his views. He includes among the results of sexual abstinence orchitis, frequent involuntary seminal emissions, impotence, neurasthenia, depression, and a great variety of nervous disturbances of vaguer character, involving diminished power of work, limited enjoyment of life, sleeplessness, nervousness, and pre-occupation with sexual desires and imaginations. More especially there is heightened sexual irritability with erections, or even seminal emissions on the slightest occasion, as on gazing at an attractive woman or in social intercourse with her, or in the presence of works of art representing naked figures. Nyström has had the opportunity of investigating and recording ninety cases of persons who have presented these and similar symptoms as the result, he believes, of sexual abstinence. He has published some of these cases (_Zeitschrift für Sexualwissenschaft_, Oct., 1908), but it may be added that Rohleder ("Die Abstinentia Sexualis," ib., Nov., 1908) has criticized these cases, and doubts whether any of them are conclusive. Rohleder believes that the bad results of sexual abstinence are never permanent, and also that no anatomically pathological states (such as orchitis) can be thereby produced. But he considers, nevertheless, that even incomplete and temporary sexual abstinence may produce fairly serious results, and especially neurasthenic disturbances of various kinds, such as nervous irritability, anxiety, depression, disinclination for work; also diurnal emissions, premature ejaculations, and even a state approaching satyriasis; and in women hysteria, hystero-epilepsy, and nymphomaniacal manifestations; all these symptoms may, however, he believes, be cured when the abstinence ceases.
