12 week scan... any possibility of seeing gender?

Has anyone ever asked the sonographer to have a quick look and see if they can see the gender at their 12 week scan?

I’ve read quite a few people on here have had their gender revealed at 12-13 week scans, especially if it’s a boy, but I think they’re mostly American!

What’s the response likely to be in the UK with the NHS? Would they refuse to even look?
