Just like milk, [condoms](https://www.bedsider.org/birth-control/condom#side_effects_tab) can go bad… And when they do, they can break more easily. That’s why you should always check the [condom’s expiration date](http://goaskalice.columbia.edu/condom-expiration-dates) and [give the wrapper a thorough inspection](https://www.bedsider.org/questions/306) before opening it.
Heat, sun, moisture, and fluorescent light can also make condoms more likely to break. To reduce the risk of breakage, store your condoms in a cool, dry place.
