Androgen

One of a class of steroid hormones. Androgens play a major role in the development and maintenance of masculine secondary sexual characters, for example, the seminal vesicle and prostate gland of the male mammal, and the comb, wattles, and spur of the male fowl. They also influence certain other secondary sexual characters, such as hair growth pattern and voice quality in humans. In the fowl, they affect the pattern and seasonal coloration of its feathers, as well as crowing. In addition, androgens affect nitrogen metabolism (anabolic). Androgens are produced in the testis, ovary, adrenal, and most likely, in the placenta. A small portion of the androgen is from corticoids, or adrenal cortex steroids, and from other C21 steroids, such as progesterone. See Hormone, Ovary, Progesterone, Steroid, Testis

The mechanism by which adrenal androgens, including DHEA-S, are regulated is not completely understood and even though ACTH is known to stimulate DHEA-S secretion, there are clinical scenarios such as a Cushing disease and ectopic ACTH syndrome that have reported DHEA-S concentrations to be normal or even low [32-34].
The adrenal glands produce testosterone, pregnenolone, aldosterone, DHEA, progesterone, estrogen, and adrenal androgens. Underproduction causes downstream depletion of sex hormones, which can be a strong trigger for the symptoms of both female sexual dysfunction and menopausal transition.
The reason for the relatively rare occurrence of mid-childhood ache is that, normally, adrenal secretion virtually ceases after the first year of life until around 7 years of age, when an increase occurs in adrenal androgen production.
(11) A potential end result of adrenal hyperfunction is the excess production of one of the three corticosteroids; Cortisol, aldosterone or adrenal androgens.
Genetics, Pwpiombactcnum acnes colonization, and stress-related production of adrenal androgens are among the factors that have been implicated, observed Dr.

In this collection of ten articles international experts describe their research in adrenal development and disorders, steroidogenic enzymes, adrenal androgens in humans an nonhuman primates, androgen synthesis and its clinical implications, a new form of congenital adrenal hyperplasia, long-term outcomes of prenatal treatment of congenital adrenal hyperplasia, syndromes involving adrenocorticotropin resistance, corticotrophin-independent Cushing Syndrome, and adrenal steroidogenesis and arterial hypertension.
The cortical hormones include glucocorticoids, aldosterone, and the adrenal androgens. Glucocorticoids stimulate gluconeogenesis, protein metabolism, and lipolysis, and aldosterone is a major controller of sodium balance and volume status.
Not surprisingly, adrenal androgens and bone parameters were lower among the 12 postmenopausal CAH patients, compared with the 14 still premenopausal women, he said.
Although this pioneering study can be criticized for its lack of an experimental control group, its extremely limited sample size, and its use of a physically traumatized participant population, the results strongly suggested that adrenal androgens do influence what Waxenberg et al.
The mechanism by which the vitamin works is unknown, the textbook notes, but may be related to alteration of blood levels of various hormones, including adrenal androgens and gonadotropins.
Dexamethasone's capacity to drastically reduce adrenal androgens is useful in reducing excessive body hair growth in women resulting from an excessive production of adrenal androgens.
