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.

a class of disorders associated with 5α-steroid reductase deficiency, testicular feminization, and related disorders. Compare: steroid 5α-reductase, Reifenstein syndrome, infertile male syndrome, testicular feminization syndrome.

androgen insensitivity syndrome

n.
An inherited condition in which the body cells are completely or partially unable to respond to androgens, resulting, in the complete form, in a person with an XY karyotype developing typical female external genitalia but usually no uterus, a short vagina, and undescended or partially descended testes. People with mild or partial forms are infertile and have a variety of phenotypes.
