I have a similar explanation to this dropping hormone levels phenomenon.

It is simply just that it does not require to be a 'manly man' in these days to have the same amount of "success", as it required in the old times. For example, take the whole mating game. Earlier, you had to look good/manly, need some quick thinking, timing and wit to pick up women. But now those things are not so much required.

I think multiple factors have contributed to this. But I think the all encompassing one is capitalism. And things like these are the an emergent result, of trying to maximize profits, and thus it is molding the very source that it generate the profit from, namely the human population. Simply put, much less profits can be made from a manly (manliness being comprised of things like but not limited to, looks, having some individuality, own principles and views and a taste for independence) and intelligent population than it can be made from a feeble/stupid, but heavy earning population. I am not saying that there is some conspiracy that is trying to accomplish this. But it might be a case of a death by a thousand paper cuts. I mean, like every time you try to sell something to the public, by social conditioning, you might be inadvertently contributing to things like this...
