androgen

 [an´dro-jen]
any steroid hormone that promotes male secondary sex characters. The two main androgens are androsterone and testosterone. Called also androgenic hormone. adj., adj androgen´ic. 

The androgenic hormones are internal endocrine secretions circulating in the bloodstream and manufactured mainly by the testes under stimulation from the pituitary gland. To a lesser extent, androgens are produced by the adrenal glands in both sexes, as well as by the ovaries in women. Thus women normally have a small percentage of male hormones, in the same way that men's bodies contain some female sex hormones, the estrogens. Male secondary sex characters include growth of the beard and deepening of the voice at puberty. Androgens also stimulate the growth of muscle and bones throughout the body and thus account in part for the greater strength and size of men as compared to women.
androgen insensitivity syndrome complete androgen resistance.

an·dro·gen

(an'drō-jen),
Generic term for an agent, usually a hormone (for example, androsterone, testosterone), which stimulates activity of the accessory male sex organs, encourages development of male sex characteristics, or prevents changes in the latter due to castration; natural androgens are steroids, derivatives of androstane.
Synonym(s): testoid (2)

androgen

/an·dro·gen/ (an´dro-jen) any substance, e.g., testosterone, that promotes masculinization.
adrenal androgens  the 19-carbon steroids synthesized by the adrenal cortex that function as weak steroids or steroid precursors; e.g., dehydroepiandrosterone.

androgen

(ăn′drə-jən)
n.
A steroid hormone, such as testosterone or androsterone, that controls the development and maintenance of masculine characteristics. Also called androgenic hormone.

androgen

[an′drəjin]
Etymology: Gk, andros + genein, to produce
any steroid hormone that increases male characteristics. Natural hormones, such as testosterone and its esters and analogs, are primarily used as substitution therapy. androgenic, adj.

an·dro·gen

(an'drŏ-jen)
Generic term for an agent, usually a hormone (e.g., androsterone, testosterone), which stimulates activity of the accessory male sex organs, promotes development of male sex characteristics, or prevents changes in the latter that follow castration; natural androgens are steroids, derivatives of androstane.

androgen

one of several types of male hormone that stimulate the development and maintenance of the male's SECONDARY SEXUAL CHARACTERISTICS. Naturally occurring androgens (e.g. TESTOSTERONE) are STEROIDS which are produced mainly in the testis (see INTERSTITIAL CELLS), but also to a small extent in the OVARY and ADRENAL CORTEX.

Androgen

A natural or artificial steroid that acts as a male sex hormone. Androgens are responsible for the development of male sex organs and secondary sexual characteristics. Testosterone and androsterone are androgens.
