III. SEXUAL EPOCH OF THE MENOPAUSE.
The Menopause.
That time in a woman’s life at which her sexual activities come to their natural termination, marked by the cessation of menstruation, is known as the menopause, climax, or climacteric period.
This “change of life,” from a condition of sexual maturity to a condition of quiescence of sexual functions, is not a sudden one, the symptoms of sexual retrogression making their appearance gradually, until the cessation of the monthly recurring menstrual flow indicates that the termination of sexual activity has arrived, and that sexual death is taking place.
The influence of this period of life is not manifested by the sexual organs alone—in these latter indeed various changes may be detected already before the cessation of menstruation, whilst after that cessation, the atrophic changes characteristic of old age proceed in these organs with a slow but continuous advance,—but the disturbances evoked by the climacteric involve the entire organism and affect the functions of numerous organs, giving rise to a true storm of irritant phenomena, and to manifestations of decay of manifold nature.
The stormy manifestations, the occurrence of which led the ancients to denote this period as the “critical age” of a woman’s life, are in the first place due to changes in the ovaries; the tissue changes in these organs give rise to a powerful ovarian stimulus, which, by irradiation and reflex action, leads to the occurrence of a number of nervous disturbances, vasomotor manifestations, and circulatory disorders; whilst owing to the cessation of the internal secretions of the ovaries, numerous and intense pathological disorders of metabolism arise. These various symptoms become apparent at the very outset of the menopause, when the oncoming entire cessation of menstruation is already foreshadowed by irregularity in the periods, gradual diminution in the quantity of the flow, and variations in the number of days during which the flow on each occasion persists.
The manifestations of the menopause are in fact so striking, that from ancient times down to the present day a widespread belief has prevailed that especial danger to a woman’s life is threatened by the climacteric age. The statistics available on this subject are, however, of dubious significance. Although it cannot be denied that the changes in the entire organism which attend the extinction of sexual activity, bring numerous dangerous influences into play, yet I feel bound to maintain that these dangers are by no means so great as those which are involved by the sexual life in its ripest period of development—the dangers of pregnancy, parturition, and the puerperium.
It is often asserted that in this “critical period” of the menopause, the mortality of the female sex is notably increased. The data available are somewhat conflicting, but a careful examination leads us to believe that, if due allowance is made for the natural increase in mortality with advancing years, no important increase in the mortality of women can be traced as due to the troubles and disturbances of the climacteric period.
The age at which a woman’s last sexual epoch begins is a very variable one. The duration of the “change of life,” the length of time during which the occurrence of the “change” is manifested by local and general disturbances, also varies greatly. Not less variable are the intensity and the general distribution of the symptoms which mark the climacteric.
