My knowledge about human physiology is quite limited, so for some people with more knowledge then me about this stuff this may seem like a stupid question. Everyone knows that the penis grows during a boys puberty. The reason for this is as far as know due to hormones. Shouldn't it be possible that with some kind of hormone treatment or something similar to restart the process that made the penis grow in the first place? Maybe we don't have the right kind of pills or whatever for this to work today, but it doesn't seem like something that's is totally illogical and impossible. We know whats starts the puberty and we know what ends it, so why aren't we able to do this? I'm not talking about restarting the whole puberty (what I fucking mess that could become), just the process that made the penis grow.
