Studies in the Psychology of Sex, Volume 1 The Evolution...

In another case which has reached me from the United States, the data are slighter, but deserve note, as the subject is a trained psychologist, and I quote the case in his own words. Here, it will be seen, there appears to be a tendency for the ecbolic cycle to cover a period of about six weeks. In this case, also, there is a tendency for the climax to occur about Saturday or Sunday. "X. is 38 years old, unmarried, fair health, pretty good heredity; university trained, and engaged in academic pursuits. He thinks he may have completed puberty at about 13, though he has no proof that he was in the full possession of his sex-powers until he was 15 years 3 months old (when he had his first emission). His sex life has been normal. He masturbated somewhat when he slept with other boys (or men) during early manhood, but not to excess.

"During the autumn of 1889 (when 28 years of age) he observed that at certain times he had an itching feeling about the testicles; that he felt slightly irritable; that the penis erected with the slightest provocation, and that this peculiar feeling usually passed away with a nightly emission. Indeed, so regular was the matter that he usually wore a loin garment at these times, to prevent the semen getting on the bedding. This peculiar feeling ordinarily continued for two or three days. He recalls at these times that he felt that he would like to wrestle with some one, for there seemed to be a muscular tension. These states returned with apparent regularity, and the intervals seemed to be about six weeks, though no effort was made to measure the periods until 1893. The following notes are taken from the diaries of X.:—

"These observations were not recorded after 1893. X. thinks that in 1894 the intervals were longer, an opinion which is based on the fact that for a period of six months he had no sexual intercourse and no nightly emissions. The times during this six months when he had the 'peculiar feeling,' the sensation was so slight as to be scarcely noted. In 1895, the feeling seemed more pronounced than ever before, and X. thinks that it may have recurred as often as once a month. In 1896, 1897, and 1898, the intervals, he thinks, lengthened—at times, he thought, wholly disappeared. During 1899, while they did not recur often, when they did come the sensation was pronounced, although the emission was less common. There was a peculiar 'heavy' feeling about the testicles, and a marked tendency towards erection of the penis, especially at night-time (while sleeping). X. often awoke to find a tense erection. Moreover, these feelings usually continued a week.

In another case, that of F. C., an Irish farmer, born in Waterford, the data are still more meagre, though the periodicity is stated to be very pronounced. He is chaste, steady, with occasional lapses from strict sobriety, healthy and mentally normal, living a regular open-air life, far from the artificial stimuli of towns. The observations refer to a period when he was from 20 to 27 years of age. During this period, nocturnal emissions occurred at regular intervals of exactly a month. They were ushered in by fits of irritability and depression, and usually occurred in dreamless sleep. The discharges were abundant and physically weakening, but they relieved the psychic symptoms, though they occasioned mental distress, since F. C. is scrupulous in a religious sense, and also apprehensive of bad constitutional effects, the result of reading alarmist quack pamphlets.

Finally, an interesting contribution to this subject, suggested by this Study, has been made and published (in the proceedings of the Amsterdam International Congress of Psychology, in 1907) by the well-known Amsterdam neurologist and psychologist, Dr. L. S. A. M. Von Römer under the title, "Ueber das Verhältniss zwischen Mondalter und Sexualität." Von Römer's data are made up not of nocturnal involuntary emissions, but of the voluntary acts of sexual intercourse of an unmarried man, during a period of four years. Von Römer believes that these, to a much greater extent than those of a married man, would be liable to periodic influence, if such exist. On making a curve of exact lunar length (similarly to Perry-Coste), he finds that there are, every month, two maxima and two minima, in a way that approximately resemble Perry-Coste's curve. The main point in Von Römer's results is, however, the correspondence that he finds with the actual lunar phases; the chief maximum occurs at the time of the full moon, and the secondary maximum at the time of the new moon, the minima being at the first and fourth quarters. He hazards no theory in explanation of this coincidence, but insists on the need for further observations. It will be seen that A. N.'s results (ante p. 117) seem in the main to correspond to Von Römer's.
