The Effects of Testosterone on the Brain

The amygdala, this fear center in the brain, has androgen receptors. And so when humans are taking low doses or reasonable doses of testosterone or they're increasing their testosterone it's a drive. Just like sex is a drive or drinking water when you're thirsty is a drive. This stuff is all anchored deep within the hypothalamus. That makes sense why young men in particular are really driven to hard exercise and sports that are very difficult that require extreme effort completely makes sense.
