Called also androgenic hormone. adj., adj androgen´ic.

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.
