Oh no, I wasn't looking at it in a "conventional" manner, I was just curious how the hormones functioned to get the dwarves to have beards. But it does make sense how they would have a totally different set and levels of hormones, particularly the growth hormone. Hehe. 

But from an evolutionary view, how would they conceive? I'm guessing they'd be able to differentiate a female from a male? I'm getting too bogged down in this, allow it lol
