the firemen happened, at least in this study to have lower testosterone levels on average than the professors or the physicians was because firemen have lower testosterone levels or because they have a much more stressful job and their cortisol levels are higher than the professor or the physician and cortisol and testosterone, not always, but generally are in somewhat antagonistic push-pull mode because they derive from the same precursor, et cetera. Typically, when cortisol is high, testosterone tends to be lower and vice versa.
if you spike your cortisol just briefly during the day because you have some sort of stressful event that's not going to inhibit your testosterone in fact it probably is going to boost your testosterone levels somewhat however if your cortisol levels are chronically elevated yes indeed it's likely that you're going to suppress your total and or free Unbound forms of testosterone
