To what extent do female and male brains differ biologically, not taking into account cultural conditioning?

I have a friend who thinks female and male brains are literally the same before social conditioning. He's a feminist, and his argument seems to be based in ideology rather than science, so I just want to ask the question to you guys to resolve my confusion.

Just in basic biological terms, how does the brain of each sex differ, if at all?

It should be noted though, that we have seen big differences between men and women when it comes to things like autism or depression that can't be explained simply by conditioning. But that indicates mostly hormonal involvement.

Behaviour differences have a lot to do with minor physiological traits people not always recognise: size, metabolism, hormonal state, being hungry, sleepy, cold. That doesn't influence the mental *capabilities* of a brain. 

So it's probably not very interesting in what way "dead" brains of men and women differ, but in what ways they react differently to triggers.
