Yes I understand what you're saying and I am not saying they are equally severe. We just rarely hear about the male side even though it is more common.

As for the research and evidence on sensitivity. I think the problem is there is no really good way to research this ethically. It would also be hard to get funding for this given the controversies and the fact that there is nothing in it for drug companies. Also if you have had it done as a child then you don't know any better so can't really say what you have or haven't lost.
