Menstruation, or the monthly flow of blood
from the genital organs, which manifests itself
in the human female from the time of puberty,
is but one evidence of a periodic excitation
that affects her whole organism.
The phenomenon particularly reacts upon the
entire nervous system, blood-vascular system,
and internal chemistry, and through these
processes, all the organs and tissues feel the
impress of the periodic movement.
The menstrual period in itself, as has been
recognized in more recent years, is but the
climax of a monthly physiological cycle which
influences throughout the month the whole of
woman’s physical and psychic organization. As
Havelock Ellis has stated, whatever organic
activity we investigate daily with any precision,
we find traces of this rhythm. “While
a man may be said, at all events relatively, to
live on a plane, a woman always lives on the
upward or downward slope of a curve. This
is a fact of the very first importance in the
study of physiological or psychological phenomena
in women. Unless we always bear it
in mind we cannot attain to any knowledge of
the physical, mental or moral life of woman.”
It is perhaps natural that reference to the
incident of menstruation in the life of woman
should be found as far back as there exist
records of human speculation. The very
earliest ideas on the subject were based on
the assumption that menstruation was an indication
of woman’s inferiority, and stigmatized
her as “unclean.”
These notions generally were due to man’s
lack of knowledge concerning this process of
periodicity. The closely interrelated superstitions,
taboos, mythological concepts and religious
ideas of primitive and ancient times
caused the moral leaders to dogmatize over the
subject, to the extent that women are still
hampered by the traditions that began at a
very ancient, and possibly prehistoric, period.
Thus in the fifteenth chapter of Leviticus,
19-30, we are told: “And if a woman have an
issue, and her issue in her flesh be blood, she
shall be in her impurity seven days; and whosoever
toucheth her shall be unclean until the
even. And everything that she lieth upon in
her impurity shall be unclean. Every bed
whereon she lieth all the days of her issue
shall be unto her as the bed of her impurity.
But if she be cleansed of her issue, then she
shall number to herself seven days, and after
that she shall be clean. And on the eighth day
she shall take unto her two turtle doves, or
two young pigeons, and bring them unto the
priest, to the door of the tent of meeting. And
the priest shall offer the one for a sin-offering,
and the other for a burnt offering; and the
priest shall make atonement for her before
Jehovah for the issue of her uncleanness.”
This feature of the Mosaic law was also followed
by the Mohammedans, who likewise regarded
a menstruating woman as unclean, and
who remained unclean for a certain number
of days after the flow ceased, or until she had
been cleansed by ecclesiastical influence.
It is to be expected, of course, that the
earliest medical writings, under the social and
religious influence of the times, should also
evince a similar feeling toward the subject.
The early Indian book of Suśruta, and the
subsequent writings of Hippocrates, gave evidence
of this attitude.
Many savage races regard the first appearance
of the menstrual flow as the only certain
sign of puberty, and among them this is the
occasion of peculiar ceremonial rites. The advent
of puberty in savage tribes is often solemnized
by the seclusion of the girls from the
time of the first menstruation. They fast during
the period of seclusion, which sometimes
terminates in an elaborate ritual of purification.
(Thus, we again meet the old belief of
woman’s innate uncleanliness.)
As we have observed, climate has a definite
influence on the sexual development of woman,
and therefore on the age when menstruation
begins, signifying the beginning of puberty.
In the torrid zone, menstruation appears at a
very early age, on the average from 11 to 14;
in the temperate zone it appears later, on the
average from 13 to 16; and in the frigid zone
later still, on the average from 15 or 16 to 20.
The altitude above sea level and the distance
from the coast are also known to have a certain
influence. These factors are probably
caused, to an extent at least, by the scarcity
of iodine in its natural food form in high altitudes
and particularly away from the coast.
In salt water fish and marine foods this important
element, which influences the bodily metabolism,
is present in liberal quantities, while
in all the foods prevalent away from the coast
and in mountainous regions, there is a lack
of natural iodine that often has an injurious
effect upon the system. For some reason or
other, women seem to be the greater suffers
from this deprivation, and the incidence of
goitre is often traced to this cause.
Race and constitution also have a decided
influence upon the appearance of puberty. In
women of the Semitic races it occurs earlier
than in woman of the Aryan races. The average
age at which menstruation begins in Jewish
girls is from 14 to 15; in Magyar (Hungarian)
girls from 15 to 16; in girls of the Germanic
races, from 16 to 16-1/2, and in the Slavonic
girls from 16 to 17 years.
Generally speaking, puberty manifests itself
earlier in girls of a sanguine, lively temperament
and a strong constitution than in those
of a phlegmatic temperament and a weakly
constitution. Furthermore, other things being
equal, menstruation appears earlier in brunettes, girls
with black hair, thick skin, dark
eyes and a dark complexion, than it appears
in blondes, girls with light hair, thin skin, blue
eyes, and a fair complexion.
Social circumstances and conditions of life
are also influencing factors. According to
Kisch, in the higher classes of society, and
among the well-to-do, whose mode of living is
luxurious, and whose social circumstances allow
free play to the imagination, menstruation
appears earlier than among women of the laboring
classes who are compelled to exert
themselves for a bare living.
In cities and large towns, too, menstruation
is observed to appear earlier than in the small
towns, while in the open country it is still further
delayed.
The initial appearance of menstruation is
commonly preceded by various symptoms,
among which are: A dragging sensation in the
loins; an indefinite feeling of pressure in the
lower part of the pelvic regions, especially in
the neighborhood of the uterus and the
ovaries; alternating sensations of heat and
chilliness, sometimes accompanied by actual
though slight change of temperature. Not infrequently
there are also disturbances in the
intestinal evacuations and urinary secretion,
and in the functional activity of the gastro-intestinal
canal. A commonly observed symptom
is an increased irritability of the entire nervous
system, with a tendency toward melancholy
and indefinite amorous desires.
The nervous irritability usually asserts itself
before the incident of the menstrual flow by
headache and moodiness, nervous irritability,
and low spirits. There may be further slight
changes in the facial aspect, dark rings around
the eyes, spontaneous blushing, uneasy sensation,
loss of appetite, a sensation of pressure
in the abdomen, palpitation, vertigo, feeling of
weakness and numbness in the lower extremities,
etc.
Courty enumerates the following symptoms
which are observed in the majority of girls before
the first appearance of menstruation:
Swelling and tenderness of the breasts, sensation
of fullness and weight in the gastric region,
gas in the intestines, a watery-mucous
vaginal discharge, finally, an itching sensation
in the genital organs.
These manifestations may also assume a
morbid character, taking the form of violent
abdominal or pelvic pains, general fatigue and
weakness, dyspepsia and diarrhea, various
kinds of neuralgia, and sometimes a degree of
moral aberration.
After the first menstruation, two or three
months may elapse before the girl menstruates
again, but after a year the flow usually recurs
at quite regular periods. Sometimes the early
periods are very violent and happen with more
than ordinary frequency, every twenty days,
for instance.
It is interesting to note that some traces of
a menstrual period are found among the higher
mammals, such as the mare and cow, and also
the bitch. Among monkeys and apes in their
wild state there is a well-marked menstrual
discharge.
In the higher apes, when they do not suffer
from captivity, the flow is said to be sometimes
quite as copious as in women. Some species
of monkeys become swollen and brilliantly
pigmented, and give other characteristic evidences
of their condition.
As a general rule, however, menstruation, in
its fully developed form, may be considered a
human characteristic. Not only is the flow
more marked as the mammal approaches Man,
but among the lower races of human kind it
is less pronounced than among the higher
races. Dr. Holder has found, for instance, that
the American Indian women menstruate for
two days only.
Ellis remarks that in the early history of the
race menstruation can but rarely have occurred;
the greater part of woman’s sexual life
having been taken up by pregnancy and very
prolonged lactation. Pinard observed that, as
menstruation is the expression of the abortion
of an unfertilized ovum, “under natural conditions
a healthy woman would never menstruate.”
Natural conditions, of course, imply
that woman would always either be in a pregnant
state, or nursing a child, so that between
the two, there would be no opportunity to
menstruate.
I have remarked that the menstrual period
is but the climax of a monthly physiological
cycle. However, this climax has more far-reaching
results in some women than in others.
Sensitive women, with high-strung nerves,
or more particularly of unstable organization,
are apt to feel the effects in a very pronounced
manner. But even normal, healthy women, under
conditions of modern life, experience the
reactions to a greater or lesser degree.
Kisch, after citing the purely pathological
cases, states: “Finally, we may have to do
with isolated sporadic occurrences in which
the exciting influence of menstrual processes
may be traced. Thus, for the outbreak of a
periodical menstrual psychosis (insanity), an
especially temporary predisposition must exist,
connected with the great development epoch of
the sexual life.
“There is, for instance, a group of transitory
states occurring during menstruation, and taking
the form of disorders of the intelligence or
of explosive emotional states; such may be witnessed,
not in those suffering from psychopathic
predisposition, but in quite healthy individuals.”
Menstruation throughout the course of the
sexual life may, like the first menstrual flow,
but with less intensity, give rise to manifestations
of nervous and mental disorders. Many
women who are otherwise healthy, suffer during
menstruation from nervous irritability, ill-temper,
low-spiritedness, neuralgia, and even
hysterical and epileptic attacks. These disturbances
occur chiefly on the first and second
days of the flow, and disappear toward the end
of the period.
The manifestations are more extreme in individuals
weakened by inordinate losses of
blood, or by deep-seated disorders in various
organs. They are also severe in those predisposed
to such disturbances from neuropathic
inheritance, and more severe in women chronically
troubled with painful or excessive menstrual
flow.
In his work on the influence of the so-called
menstrual wave on the course of mental disorders,
Schule observes that the mental equilibrium
even of a perfectly healthy woman is not
a stable one, but is subject to a series of oscillations.
The menstrual period, he continues,
has a distinct influence on woman’s mental
equilibrium.
Even in those who are possessed of a healthy
nervous system, menstruation evokes a state,
now of depression, now of excitement; in
neurotic women on the other hand, menstruation
may give rise to nervous diseases which
may equally exhibit the characteristics of depression
or the characteristics of excitement.
In nervously predisposed women, the influence
of regularly established menstruation,
even when the circumstances are favorable, is
pretty much the same as the influence of menstruation
when it first makes its appearance;
the influence is merely somewhat weaker
insofar as the woman has learned to endure
and to be patient. The menstrual state, in
nervously predisposed women evokes the particular
neurosis to which the individual happens
to be liable. The disorders most commonly
met with in this association are hysteria,
hemicrania (neuralgia on one side of the head),
swimming of the head, epileptic paroxysms,
toothache, and neurasthenia.
The characteristic form of neuralgia is
especially frequent. Sometimes it may begin a
day or two before menstruation, and may accompany
its whole course, becoming however,
less severe toward the end of the flow.
Hysteria most commonly manifests itself on
these occasions by a depressed emotional state,
by tearfulness, by complaints made without
sufficient grounds, sometimes by muscular
spasms, but very rarely by epileptic seizures.
There are also numerous other evidences of
variation from the normal state, but not
observable to the untrained eye, or in many
instances without special tests. For instance,
Cullen discovered long ago that the pulse rate
rises at the approach of the periods. Stephenson
found a monthly cycle with respect to
arterial tension and pulse rate. Giles’ investigations
showed the greatest blood pressure on
the first two days of menstruation and the day
preceding.
Thirst is often present, and urination more
frequently than usual. There is also a tendency
to pigmentation; the pigmented circle
around the nipple usually becomes darker, the
complexion is changed, losing its clearness, and
a dark ring may sometimes be perceptible
around the eyes.
According to various authorities, the temperature
is at its highest point a few days
before actual menstruation. Silva makes the
interesting observation that the alkalinity of
the blood is reduced during the period, and the
vasomotor system reacts to stimuli in the same
way as in states of fever.
Havelock Ellis thinks there is little doubt
that a daily examination of any of the senses
would show a monthly rhythm. He is only
acquainted with one series of observations on
this point, namely those of Finkelstein of St.
Petersburg, who studied the functional activity
of the eye during menstruation in twenty
healthy women, aged between nineteen and
thirty-three.
Finkelstein found that during the period
there is a concentric narrowing of the field
of vision, beginning one, two, or three days
beforehand, reaching the greatest intensity on
the third or fourth day of menstruation, and
gradually disappearing on the seventh or
eighth day after its appearance. The narrowing
of vision is more pronounced in those
women in whom menstruation is associated
with headache, cardiac palpitation, and other
nervous symptoms, as well as in those who
lose large quantities of blood.
Not only the field of vision for white, but
also the visual fields for green, red, yellow and
blue undergo a regular diminution. Perversion
of perception of green (which is seen as yellow)
is observed fairly often (in 20 per cent
of all cases).
It would be fair to assume that careful observation
of the other sense organs would
yield similar proof of monthly periodicity.
Lennox Browne, a prominent specialist,
wrote to Havelock Ellis, as follows, on the influence
of normal menstruation on the voice:
“With regard to singers, I believe that the
pitch of the voice is often lowered at the
menstrual epoch, although I have not found
this to be universally admitted by patients to
whom I have spoken on the subject. Many
have told me that they have a disposition to
sing flat, and in two cases in my recollection
the patients, who suffered from dysmenorrhea
(painful menstruation), told me that they sang
sharp, of which they were conscious—probably
from information, for of course you know that
those who sing sharp are not generally sensible
of the defect. It is, however, generally
agreed that the timbre and tone-quality is impaired,
the voice being decidedly thinner and
poorer during the epoch.”
So well is this fluctuation of the voice recognized
that in Continental Europe, it is not considered
desirable for public singers to appear
during the menstrual period. In fact, it is the
custom on the Continent, when making engagements
with female singers, to provide for the
suspension of duty during the menses, but this
does not apply in English or American contracts,
although the impresario is in practice
obliged to recognize it.
To bring the subject from the realm of art
down to the more prosaic sphere of the household,
Clouston thinks it probable that the superstitions
regarding the evil influences exercised
by women at their periods on foods,
etc., which they prepare, are based on the actual
decreased success in such operations at
this time, due merely to a physiological decrease
in energy and skill.
The organic character of menstruation is
well sustained by these many widely diversified
evidences of its manifestations. The incident
of vicarious menstruation, however,
throws a further interesting light on the subject.
Vicarious menstruation has been observed in
cases in which, as a consequence of morbid
conditions of the uterus, or of the organism
as a whole, the menstrual flow has at the time
of puberty either failed entirely to appear or
has been exceedingly scanty. When conditions
of this kind have prevailed, hemorrhages from
other organs have, since ancient times, been
witnessed and are regarded as vicarious menstruation.
As the congestion that occurs during menstruation
is not limited to the genital organs,
when the flow of blood from the uterus fails
to occur, the organism seeks another outlet, in
order to restore the disturbed equilibrium of
blood distribution. Vicarious flowing of blood,
in these instances, may take place from the
mouth, the nose, the intestines, the anus, the
gums, the breasts, the ears, the lungs, or even
the eyes.
These evidences of true vicarious menstruation
must not, of course, be confused with
hemorrhages due to genuine organic disease,
such as tuberculosis, gastric ulcer, etc.
Numerous authorities have collected data regarding
this phenomenon. Puech found, in the
cases he collected, that vicarious menstrual
hemorrhage occurred from the stomach thirty-eight
times, from the mammary glands twenty-five
times, from the lungs twenty-four times,
and from the nasal mucous membranes eighteen
times. In all cases menstruation had been
long in abeyance. The regular monthly recurrence
of the vicarious discharge is often
marked.
