[@Torack] That's why I said monogendered- there are plenty of animals out there that have genders that do not in any way mimic the supposed binary imposed by Western societal convention. Chromosomes and hormones themselves don't work on a binary system. To measure the length and shape of a chromosome to determine gender is actually an inexact science, hence the existence of intersex people, and people with extra or too few chromosomes. Progesterone, estrogen, testosterone, oxytocin, vasopressin, and I'm probably forgetting some. Each hormone contributes to different processes within the human body; for example, an increase in testosterone is one of the factors which brings about the painful part of the menstrual cycle. Dwarves, I'm supposing, would have an entirely different set of hormones, or different levels than humans altogether. Really low levels of estrogen and testosterone, and other hormones that contribute to growth, at a young age, which only increase as puberty ends, with high levels of testosterone for all, idk. Hell, I'm guessing entirely different hormones are there to start with for dwarves, and that for them, facial hair is not a secondary sex characteristic, just a characteristic of all dwarves.
