    Definitely increases the level, but not much. Recently, scientific articles looked at this.

    Too much of the jittery juice increases cortisol, which decreases testosterone. Moreover, consuming caffeine late in the day hurts sleep, which lowers testosterone production. But one recent study indicate that caffeine consumed before working out may improve testosterone levels and help you exercise more efficiently.

    Testosterone is a vital sex hormone that boosts muscle formation, facial hair and genital development. In an effort to avoid substances that may decrease testosterone, some athletes and bodybuilders shun caffeine, but it appears that caffeine may actually increase testosterone. Caffeine doesn't come without side effects, however, so it shouldn't be used to excess or to treat severe testosterone imbalances.

    RESULTS: Testosterone concentration showed a small increase of 15% (90% confidence limits, +/- 19%) during exercise. Caffeine raised this concentration in a dose-dependent manner by a further small 21% (+/- 24%) at the highest dose. The 800-mg dose also produced a moderate 52% (+/- 44%) increase in cortisol.

    I work as an endocrinologist in a hospital and not long ago we considered this case. As a rule, coffee does not contain male and female hormones, this misconception is not supported by any scientific research. I had a case when a girl came to consult if the use of dairy products promotes breast enlargement. I cannot understand where such ideas and theories come from. As a rule, in such situations, we advise you to pay attention to the research of Sandra Hale, which deals with issues of female breast augmentation without surgery. If you are curious you can find more information at curvesfw.com. Don't build theories, trust science.

    Among males, consumption of caffeinated coffee increased total testosterone & decreased total & free estradiol.

    Among females, decaffeinated coffee decreased total & free testosterone & caffeinated coffee decreased total testosterone.
