The assumption is generally that female physiology is essentially the same as male physiology, minus a few key hormonal differences (some deserving more attention than others). The rest has, so far, been chalked up to psych0-social stuff. You can certainly understand why that is. However, new indications to the contrary keep turning up.
Obviously, there needs to be a lot more research before we’re able to make any definitive conclusions but that’s the problem in the first place, isn’t it?
