Could have cultural roots, in that women spend a lot of effort trying to appear younger even when they aren't that old, whereas men don't start until their hair is falling out.

Which could be based on the biological attractiveness of a younger and presumably more fertile woman vs. an older and thus more fit (what, not eaten by a tiger yet?) man. Those damn genes.

Similar thing: whether women are referred to by first or last names. For example, you sometimes see men's names shortened to last names "get Jones on the phone!" but you almost never see a woman's name shortened that way... or a child's.

Luckily now you're Dr. Nomer and Dr. Frost, which still sounds good. ;)
