Is isn't anything physical, it's because of the way they grew to respect their women and the women grew more powerful than the men. I don't know how to explain it. xD
They're pretty much born knowing that the women are to not be mistreated and that they are the most fragile asset to their race. Also it takes a lot to attract a female mate and for her to accept a male as her mate. Ardonians mate for life, once they find a mate they remain with them until they die and even after they die they do not find another mate ( remarry ) they remain alone. So the females are very picky creatures. xD
