Female Dwarves do not typically grow beards til' well after childbearing age, when their naturally elevated Dwarven testosterone takes over and they often give up domestic interests to pursue martial ones.

It is not uncommon for some of the mightiest Dwarven warriors to be these honored (feared!) Matrons often with grandchildren or in some cases great grandchildren.

Due to their full beards, heavy armor and deepened voices, Matrons in battle are essentially indistinguishable from their menfolk.
