Why do men get hairy legs?

Its all to do with genes, hormones and most of all testosterone, they say the more testosterone on a man, usually the hairier and sexier he is, but that is not completely true, a bit perhaps. Most women do not have much or as much testosterone as a man, hirsute ladies, those are women who are unusually hairy also have quite a lot of male testosterone in them, but there are not too many of them.
