Good summary on this topic, I hadn't realized that testosterone is also linked to bone growth in men. Is it harder for married men to build muscle, though, given that testosterone also plays a role in muscle development?
On a more imaginative side note, if testosterone is also linked to aggression; i wonder if criminals could be treated in a way that drains testosterone. Not by giving them babies, but I've heard of prison programs have good behavior criminals care for animals and I think it helps both the animals and prisoners; maybe having pets may also drain testosterone or so to speak?
This is entirely possible and I wouldn't rule it out. Because it seems that having a wife or long-term girlfriend has the same effect as having a baby.
