It indirectly decreases your testosterone levels by inducing the production of cortisol
On the other hand it increases your metabolic rate (which is good if you're trying to lose weight)
Consuming it in large quantities on a regular basis can cause you to be constantly fatigued, but if you limit your intake to a few cups of coffee a week (1 or less cup a day) you'll be fine I guess
