The dual hormone hypothesis states that testosterone substantially interacts with the stress hormone cortisol in order to exert its assumed affects on dominance behavior and mating drive. Cortisol is thought to inhibit these effects when levels are high, and androgens generally have the effect of inhibiting cortisol release. Thus the ratio between the two hormones is thought to be more important than levels of either one on their own, in terms of driving behaviors such as approach/avoidance, status seeking, violence, and sex drive. | The dual hormone hypothesis states that testosterone substantially interacts with the stress hormone cortisol in order to exert its assumed affects on dominance behavior and mating drive.

For example, some evidence shows increased testosterone shows no relation to increased male sexual desire with the concurrent presence of high cortisol levels | For example, some evidence shows increased testosterone shows no relation to increased male sexual desire with the concurrent presence of high cortisol levels. | ||
The fact that increased testosterone alone doesn't increase male sex drive provides some support for the dual hormone hypothesis. It is said some effects of testosterone become potentiated in the presence of lower levels of the stress hormone cortisol and suppressed when higher levels of this hormone are present.<ref>https://psyarxiv.com/42t6e/</ref> | The fact that increased testosterone alone doesn't increase male sex drive provides some support for the dual hormone hypothesis.
