The effects of AS and testosterone derivatives upon road aggression are also subject to research. Ellingrod et al. (1997) conducted a study using the Iowa driving simulator to discover the effects of physiologic and supraphysiologic doses of testosterone cypionate. They used weekly doses of 100 mg, 250 mg and 500 mg, and then tested the driving behaviour of the subjects.

These conditions are produced by the negative feedback mechanism of AS on the male hypothalamic–pituitary axis and from local suppressive effects of AS on the testes. , 1996).
