His hormones boiled and steamed like the rolling levity of atoms and yet he did not reach for the succulent young flesh there beside him.
For we know that anything that will upset- -reduce or increase the hormones is a matter intimately concerned with health. Such changes," he said earnestly, leaning forward, "might be aimed directly at the very heart of what otherwise would be a true eugenic marriage. It is even possible that loss of sex itself might be made to follow deep changes of the thyroid." He stopped a moment.
She was able to stop taking synthetic thyroid hormones and instead, supported her endocrine system with protomorphogens. A Rampaging Infection At the age of 40, John, an old bohemian client of mine, came into a moderate inheritance and went "native" in the Fiji Islands in the South Pacific. He spent about four months hanging out with the locals.
Now they were largely self-sufficient. They grew native plants and extracted hormones in crude little chemical plants. The hormones were traded to the big chemical plants for a pittance to buy what had to come from Earth. Other jury-rigged affairs synthesized much of their food. But mostly they learned to get along on what Mars provided. Doc Feldman learned from them.
Nevertheless, they are essential to the proper maintenance of life in the body, and no less organically related to mental and psychic development as well. Through these HORMONES the secondary sexual characters are produced, including the many differences in the form and structure of the body which are the characteristics of the sexes.
And like its variations, variations of their tone, development, reactivity, fatigability, and endurance may be traced to corresponding states of overaction, or underaction, and odd combinations of the different hormones. Much remains to be learned about them and the manner of their control.
The knowledge now obtained concerning the nature and action of hormones shows that such a process actually exists, and in modern theory real substances of the nature of special chemical compounds take the place of the imaginary gemmules of Darwin's theory of pangenesis or the 'constitutional units' of Spencer.
We have considered the evidence concerning the relation of the development and functional action of the milk glands to hormones arising in the ovary or uterus, now we have to consider the origin of the glands and of their peculiar physiology in evolution.
It can have a genetic predisposition for a specific allergy to start with. It can be repeatedly exposed to an irritating substance such as pollen when, at the same time, the body's mechanism for dealing with irritations is weakened. Generally weak adrenals causes this because the adrenal's job is to produce hormones that reduce inflammation.
Man is likewise a creation of the chemical wheels within wheels and springs within springs that are his glands of internal secretion. That he is not so obviously an appendix to his testes is due to two reasons. First, the male sex hormones have not the instability nor cyclic rhythmicity of the female.
