uth, early manhood,
or even middle-age, the same changes follow as in the case of the
eunuch, the hair on face and body disappears, the voice changes from
deep to high tone, and mentally the man develops inertia and cowardice.
Physically, he puts on fat almost immediately.

When women have, for any reason, had their ovaries removed by surgical
operation, marked changes follow, which vary much in detail, but carry
certain general similarities. The face and body age rapidly in
appearance, and there is a slowing up of functions of the organs, with a
tendency to masculinity in tastes, behavior, feelings.

Noting these and many other phenomena, as many had done before him, Dr.
Brinkley concluded that the testes of the male and the ovaries of the
female performed corresponding offices for each sex, generating the
vital fluids which, when not fulfilling their primary object of
reproducing the species, were turned back into the blood and absorbed by
the tissues for the benefit of the individual's physical and mental
processes. Normal activity of the secretions of the sex-glands,
therefore, meant, in Dr. Brinkley's opinion, right nourishment for all
the cells of the body, and right functioning of all the organs of the
body. The strength and speed of the stallion in health were as much due
to the right action of the sex-glands as his full-arched neck, his
blazing eye, or his thick mane and tail. And since the capon and the
eunuch acquired a cowardice that avoided fatigue, effort, or conflict,
it was clear that the mental qualities were as directly influenced by
the testicular secretion as the physical. It followed that the
well-nourished brain, capable of sustained concentration and clear
thinking, must necessarily be the brain that was fed by the normal
activity of the sex-glands, and it also followed that since youth in man
and woman is the time of matured beauty of face and form in man and
woman, when sexual secretions are of normal activity, therefore, the
sexual secretions were mainly responsible for the development of matured
beauty of face and form. From this it was clear and evident that the
haggard face, the lined face, the over-thin or the over-fat body,
phemonena familiar to all of us in men and women who have passed their
youth, were due in the main to lack of nourishment of the body-cells by
the seminal fluid, with lack of proper functioning of the organs, and
resultant lack of proper elimination of waste matter fro
