The worst thing is that in the US the teenagers can't even sneak out to the physician without their parents noticing because health insurance is structured that way. That's part of the wider problem that teenagers in the US are far too supervised and confined.

You'd really like to hand out case photographs to the parents to show what testicular inflammation in adults looks like.
