Is it possible the failure rates get so low with modern birth control that it is almost impossible to offset with increased amount of sex? Specifically, IUDs.

Even the pill is listed at 9%, which is low, and of course, abortion is the last resort to completely prevent a birth.

For couples who are finished having children, a vasectomy also basically has a 0% failure rate.

Those are annual rates, so 9% is not low. (Planned Parenthood puts it at 7% annually, which is still 48% failure over ten years!) https://www.plannedparenthood.org/learn/birth-control/birth-...

This is an important point. The failure rate measures, "If 100 people otherwise capable of becoming pregnant have an average amount of otherwise potentially procreative sex for a year, how many of them will get pregnant?"

Nine out of every hundred is a LOT to start out with. And if the "average amount of otherwise potentially procreative sex" part increases by, say, 11%, you get one new pregnancy out of every hundred.
