If we confine ourselves to modern times and to fairly precise medical statements, we find in Schurig's Spermatologia (1720, pp. 274 et seq.), not only a discussion of the advantages of moderate sexual intercourse in a number of disorders, as witnessed by famous authorities, but also a list of results—including anorexia, insanity, impotence, epilepsy, even death—which were believed to have been due to sexual abstinence. This extreme view of the possible evils of sexual abstinence seems to have been part of the Renaissance traditions of medicine stiffened by a certain opposition between religion and science. It was still rigorously stated by Lallemand early in the nineteenth century. Subsequently, the medical statements of the evil results of sexual abstinence became more temperate and measured, though still often pronounced. Thus Gyurkovechky believes that these results may be as serious as those of sexual excess. Krafft-Ebing showed that sexual abstinence could produce a state of general nervous excitement (Jahrbuch für Psychiatrie, Bd. viii, Heft 1 and 2). Schrenck-Notzing regards sexual abstinence as a cause of extreme sexual hyperæsthesia and of various perversions (in a chapter on sexual abstinence in his Kriminalpsychologische und Psychopathologische Studien, 1902, pp. 174-178).
Pearce Gould, it may be added, finds that "excessive ungratified sexual desire" is one of the causes of acute orchitis. Remondino ("Some Observations on Continence as a Factor in Health and Disease," Pacific Medical Journal, Jan., 1900) records the case of a gentleman of nearly seventy who, during the prolonged illness of his wife, suffered from frequent and extreme priapism, causing insomnia. He was very certain that his troubles were not due to his continence, but all treatment failed and there were no spontaneous emissions. At last Remondino advised him to, as he expresses it, "imitate Solomon." He did so, and all the symptoms at once disappeared. This case is of special interest, because the symptoms were not accompanied by any conscious sexual desire.
The whole subject of sexual abstinence has been discussed at length by Nyström, of Stockholm, in Das Geschlechtsleben und seine Gesetze, Ch. III. He concludes that it is desirable that continence should be preserved as long as possible in order to strengthen the physical health and to develop the intelligence and character. The doctrine of permanent sexual abstinence, however, he regards as entirely false, except in the case of a small number of religious or philosophic persons. "Complete abstinence during a long period of years cannot be borne without producing serious results both on the body and the mind.......
Many advocates of sexual abstinence have attached importance to the fact that men of great genius have apparently been completely continent throughout life. This is certainly true (see ante, p. 173). But this fact can scarcely be invoked as an argument in favor of the advantages of sexual abstinence among the ordinary population. J. F. Scott selects Jesus, Newton, Beethoven, and Kant as "men of vigor and mental acumen who have lived chastely as bachelors." It cannot, however, be said that Dr. Scott has been happy in the four figures whom he has been able to select from the whole history of human genius as examples of life-long sexual abstinence. We know little with absolute certainty of Jesus, and even if we reject the diagnosis which Professor Binet-Sanglé (in his Folie de Jesus) has built up from a minute study of the Gospels, there are many reasons why we should refrain from emphasizing the example of his sexual abstinence; Newton, apart from his stupendous genius in a special field, was an incomplete and unsatisfactory human being who ultimately reached a condition very like insanity; Beethoven was a thoroughly morbid and diseased man, who led an intensely unhappy existence; Kant, from first to last, was a feeble valetudinarian. It would probably be difficult to find a healthy normal man who would voluntarily accept the life led by any of these four, even as the price of their fame. J. A. Godfrey (Science of Sex, pp. 139-147) discusses at length the question whether sexual abstinence is favorable to ordinary intellectual vigor, deciding that it is not, and that we cannot argue from the occasional sexual abstinence of men of genius, who are often abnormally constituted, and physically below the average, to the normally developed man. Sexual abstinence, it may be added, is by no means always a favorable sign, even in men who stand intellectually above the average.
Numerous distinguished gynæcologists have recorded their belief that sexual excitement is a remedy for various disorders of the sexual system in women, and that abstinence is a cause of such disorders.
