I've seen quite a few career women hire surrogate mothers. E.g. their eggs, the guy's sperm, but a different mother. That's certainly something that's only possible due to medical technology. Similarly, the pill was a huge revolution and there are trials for reversible male contraception as well. If all STDs are curable and everyone controls their fertility by better means, why would you bother with a condom that removes the sense of touch for one of the parties?
Also, will women still be getting pregnant in vivo? Because if so, then 'because bioengineering' wouldn't be sufficient protection from the hollow mutant zombie babies that would be produced (as a side effect of all the _bioengineering_)
