Now I know that correlation ≠ causation, but this is still an interesting concept. It's REALLY long though, so be prepared to read. Personally, I've ways believed it is because the hormones that cause you to grow (HGh, Test, etc) also have other effects that cause a masculine frame (test making one care less, HGh giving one more energy to do things, etc.) so it's no surprise to me really. But just throwing this out there.
