>>76359080 (OP)Studies show that guys in masculine environments (the military and prison were subjects used IIRC) will often have higher test levels. The exact mechanism of action isn't fully understood, for example, it could be a pheromone thing, like how females living together can get on the same menstrual cycle or it may be the aggressive and competitive culture of where they are. So there is a lot going on that we fully don't understand.
If you are getting /fit/ because you want to smash more, seeing a lot of attractive females would probably help since it gives a level of motivation.
