Where are the female Audiophiles?

Based on my limited experience, I would guess that 98% of Audiophiles are male. But 51% of our population is female. What gives?

In this age where females and males are equally represented in Universities and in the Professions, why is this still true?

I would guess that it is a cultural thing, can't be genetic can it?
Is it different in other parts of the World?
