It is possible to leave comments that are not novellas and that also are not sweepingly dismissive of underlying reality. All birth control methods have failure rates. None of them promises 100% protection -- except celibacy (assuming no one gets raped), which most married couples are not keen to practice.

I'm curious, if we take the failure rate of responsible protected sex, post-vasectomy sex, etc, for the planet...

... does that even start to contribute to replacing the existing population, or is it a statistical blip? Is this just a dead end you're trying to lead me down?
