Well it's a chicken and the egg thing. Obviously women don't infect themselves and now the pap smear, in the US includes an HPV panel. IMHO men or women can be a carrier.

Viruses such as HCV and HPV are in the frontier of modern medicine, I would bet there there are many epedemiologists who find this a subject of great interest.
