Why are condoms only 98% effective?

307 views

I just read that condoms (with perfect usage/no human error) are 98% effective and that 2% fail rate doesn’t have to do with faulty latex. How then? If the latex is blocking all the semen how could it fail unless there was some breakage or some coming out the top?

One major error I’ve heard people make is not realizing pre-ejaculate still contains sperm cells. Maybe not as much as actual semen, but enough. I’ve heard of people having unprotected sex for a good portion of time and then, as they feel they’re reaching climax, they’ll stop and put the condom on. That’s really just my understanding of how people end up pregnant after swearing up and down that whoever had the penis was wearing a condom. Sure they did in the end, but it’s kind of like putting a mask on 15 minutes into being in a room full of sick people. (This is why comprehensive sex education matters)

I’ve always wondered how condoms possibly rip? Do I not fuck with enough vigor or something? Never happened once that I’ve noticed. Are people just not getting women wet enough? Or have mammoth dinks and incorrectly sized rubbers?

Ever had it fall off and end up inside a vagina? Yeah that happens too.

Damn i can’t remember the names

Basically it covers “failures in contraceptive” and “failures in the use of contraceptives” — there’s fancy names for these things that i can’t recall.

edit: oh, its perfect-use and typical-use.

*98% effective when used as the primary birth control method for a year by the typical sexually active person.

Because it has a chance of tearing or slipping off… I’ve heard many stories about the slipping off one so it seems fairly common.

On top of other answers, corporate lawyers will NEVER allow anyone to say 100% when marketing a product. Declaring a 2% failure rate provides for significant protection from lawsuits.

Also keep in mind that when they say with perfect usage what they mean is that the people who had them fail *reported* perfect usage. A reasonable chunk of those people probably did make an error in usage it’s just that either they didn’t know they made a mistake or they were embarrassed about making a mistake so they said they did use it perfectly, therefore it must be the condoms fault. There were no researchers watching people shag to make sure they were using the condoms correctly.

The 2% is human mistakes. This includes putting it on wrong, putting it on after already having put the penis in the vagina, wrong sizing, storing it incorrectly, etc.

I don’t remember where I know this from but I’m positive it was a human sexuality course
