That doesn't particularly surprise me. Though I don't really buy the 'female brain' idea in the way it has been proposed so far and it is a fairly small sample they looked at.

I hate to say it because it's the darkness of sexual orientation/preference and sickens me like many others but it wouldn't surprise me if they also one day find such markers for paedophilia.

I think most of these things are in our genetic make up. Who would choose anything that brings misery to self or others and being conflicted often brings misery? However that doesn't mean there won't be individuals who would choose to self identify for their own purposes.
