The relationship between high and low trait psychological stress, serum testosterone, and serum cortisol.

Psychological stress, as measured by the parameters of trait anxiety, hostility, and depression, was compared in the group of males age 30-55 with serum levels of testosterone. Those males who were classified as high psychological stress had significantly lower testosterone levels than did their low stress counterparts. However, comparison of their serum cortisol values revealed similar concentrations in both groups.
