Eli5: Condom Effectiveness

605 views

What does it mean when the statistics say that condoms are, at best, 98% effective.

It sounds like 1/50 times a condom is used, it won’t prevent pregnancy. But this doesn’t seem right because those stats wouldn’t be worth the risk.

If they said 100% then people will chase the manufacturer for every pregnancy that happens when they were “using a condom” it’s much easier for them to say 98% to account for people using them wrong, condoms breaking, the occasional defective one etc…

I had a vasectomy a few years back and I’m technically 98% infertile even though my pipes are totally severed
