The question is how do the hormones affect it and what roles are suitable, not whether it happens at all. Certainly it could, but it's non-scientific to assume that because we see an effect that could be explained by it, the effect is definitely explained by it. Also I don't think it's a consensus position that men are women are differently fit for different roles, in the sense that men or women are unfit for certain roles. Humans are capable of adapting to all sorts of things.
