Everywhere I find on the internet says that condoms, when used properly and don’t break, are only 98% effective.
That means if you have sex once a week you’re just as well off as having no protection once a year.
Are 2% of condoms randomly selected to have holes poked in them?
What’s going on?
In: Biology
Effectiveness is measured by asking people what prevention they use, then coming back a year later and checking if they got pregnant.
So it can just be one out of a number of condoms during the year.
Also, I suspect it’s hard to make sure they are actually used perfectly. There won’t be three researchers ready to check after the condoms come on.
