But do they need condom ads in Europe?

I'm staying with friends over Independence Day weekend and they showed me this European condom ad. Very effective, I imagine: cute dad, terrible child, horrifying supermarket scenario.

But it did raise this question: with birthrates in Europe falling, do they really need to advertise condoms? It's hard to imagine that people are having a lot less sex so they must be pretty good at contraception. But then of course there is a need to do STI prevention, and contraception and STI prevention are two different matters. It's interesting to think about how public health policy and population/family policy can be in conflict. Imagine the tension between giving incentives to couples to have children while trying to encourage condom use to prevent disease.
