Those obvious parts are probably really a great deal at that age though. Of course the social norms are there too (and while girls can sort of stay tomboys and not face much mocking and bullying, guys don't have quite the liberty, those at least for the western world). But yeah, the basic biology must be a huge problem because of puberty.
I mean if you think of yourself as a girl, having your voice break is hardly some minor issue. Or the other way around, if a biological girl feels that's the wrong body, boobs and periods are not something you'd deal with easily. So in regards to doing this at such an early age being bad for the emotional and psychological well being... well, I don't think the above will make those people feel well in either aspect.
With this being a Sun publication I'm not sure at all what part of the story is presented, and what of the presented is true though.
