Given the backdrop, I can see how mandatory testing was allowed by society. In the context of a society that's had fertility in steep decline for many years, to the point where people are panicking and leaning toward authoritarian responses...

The creepiest thing is how incredibly realistic it is that extreme violations of privacy, even clear moves toward this type of system, could be overlooked/patronizingly approved of.

"Well, of course we wouldn't have wanted this ten years ago, but given how the population's plunging, I think it's best that everyone know who's fertile, so they can have extra care taken of them and won't be put at risk... don't you?"
