a real menstrual rhythm may be traced.[127]
It does not appear to me, however, even yet, that a final answer to the question whether a menstrual sexual rhythm occurs in men can be decisively given in the affirmative. That such a cycle will be proved in many cases seems to me highly probable, but before this can be decisively affirmed it is necessary that a much larger number of persons should be induced to carry out on themselves the simple, but protracted, series of observations that are required.
Since the first edition of this volume appeared, numerous series of ecbolic records have reached me from different parts of the world. The most notable of these series comes from a professional man, of scientific training, who has for the past six years lived in different parts of India, where the record was kept. Though the record extends over nearly six years, there are two breaks in it, due to a visit to England, and to loss of interest. Both involuntary and voluntary discharges are included in the record. The involuntary discharges occurred during sleep, usually with an erotic dream, in which the subject invariably awaked and frequently made an effort to check the emission. The voluntary discharges in most cases commenced during sleep, or in the half-waking state; deliberate masturbation, when fully awake, was comparatively rare. The proportion of involuntary to more or less voluntary ecboles was about 3 to 1. A third kind of sexual manifestation (of frequency intermediate between the other two forms) is also included, in which a high degree of erethism is induced during the half waking state, culminating in an orgasm in which the power of preventing discharge has been artificially acquired. The subject, E. M., was 32 years of age when the record began. He belongs to a healthy family, and is himself physically sound, 5 feet 6 inches in height, but weight low, due to rickets in infancy. In early life he stammered badly; his temperament is emotional and self-conscious, while his work is unusually exacting, and he lives for most of the year in a very trying climate. As a boy he was very religious, and has always felt obliged to resist sexual vice to the utmost, though there have been occasional lapses.
As regards lunar periodicity, E. M., has summated his results in a curve, after the same manner as Mr. Perry-Coste, beginning with the new moon. The periods covered include 54 lunar months, and the total number of discharges is 176; the average frequency is about 3 per month of twenty-eight days. The curve, for the most part, zigzags between a frequency of 4 and 9, but on the twenty-fourth day it falls to 1, and then rises uninterruptedly to a height of 11 on the twenty-seventh day, falling to 2 on the next day. Whether a really menstrual rhythm is thus indicated I do not undertake to decide, but I am inclined to agree with E. M. himself that there is no definite evidence of it. "It looks to me," he writes, "as if the only real rhythm (putting aside the annual cycle) will be found to be the average period between the ecboles, varying in different persons, but in my case, about nine and one-eighth days. May not the ecbolic period in men be compared to the menstrual period in women, and be an example of the greater katabolic activity of men? There is the period of tumescence, and the ecbole constituting the detumescence. The week-end holiday would hasten the detumescence, but about every third week-end there would tend to be delay to enable the system to get back into its regulation nine or ten days' stride. This might possibly be the explanation of the curves. The recent emissions were nearly all involuntary during sleep. Age may have something to do with the change in character."
E. M.'s curves frequently show the influence of weekly periodicity, in the tendency to ecbole on Sunday, or sometimes on Saturday or Monday. In recent years there has been some tendency for this climax to be thrown towards the middle of the week, but, on the whole, Wednesday is the point of lowest frequency.
In another case, the subject, A. N., who has spent nearly all his life in the State of Indiana, has kept a record of sexual manifestations between the ages of 30 and 34. The data, which cover four years, have not been sent to me in a form which enables the possibility of a monthly curve to be estimated, but A. N., who has himself arranged the data on a lunar monthly basis, considers that a monthly curve is thus revealed. "My memoranda," he writes, "show that discharges occur most frequently on the first, second, and third days after new moon. There is also another period on the fourteenth and fifteenth, which might indicate a semi-lunar rhythm. The days of minimum discharge are the seventh, eighth, twenty-second, and twenty-third." It may be added that the yearly average of ecbolic manifestations, varying between 50 and 55, comes out as 52, or exactly one per week.
A weekly periodicity is very definitely shown by A. N.'s data. Sunday once more stands at the head of the week as regards frequency, in this case very decisively. The figures are as follows:—
| Sun. | Mon. | Tues. | Wed. | Thurs. | Fri. | Sat. |
| 48 | 21 | 24 | 35 | 28 | 26 | 27 |
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.:—
"Thursday, December 29, 1892. The peculiar feeling.
(This is the only entry.)
"Thursday, February 9, 1893. The peculiar feeling.
(The diary notes that X. awoke nights to find erections, and
that the feeling continued until Sunday night following, when
there was an emission.)
"Friday, March 27, 1893. The peculiar feeling.
(The diary notes that there was an emission the next night,
and that the feeling disappeared.)
"Wednesday, May 3, 1893. The peculiar feeling.
(The diary notes that it continued until Saturday night, when
X. had sexual relations, and that it then disappeared.)
"Wednesday, June 14, 1893. The peculiar feeling.
(The diary states that the next night X. had an emission,
and the disappearance of the feeling.)
"Thursday, July 27, 1893. The peculiar feeling.
(The diary notes that it was apparent at about 3 o'clock
that afternoon. That night at 10 o'clock, X. had sexual
intercourse, and the feeling was not noted the next day.)
