Does condom storage matter?
Condoms are tested to rigorous standards, and they’re usually extremely reliable. But if they’re not stored and carried correctly, they can be damaged, which can allow fluids that can cause pregnancy to pass through. Even damage that isn’t visible to the naked eye can make condoms ineffective.
First things first — condoms have an expiration date, so check the date on the packaging and use the ones that expire soonest first. Expired condoms might not be effective. If the package is torn or damaged, throw the whole thing away. Even if the condom seems intact, if the packaging wasn’t completely sealed, the condom can dry out and become brittle and prone to breakage.
There are lots of things that can render a condom ineffective — not just sharp objects, but temperature, direct sunlight, and even being kept under a heavy book or squashed inside a wallet for a long time can cause serious wear and tear to a condom.
