Condoms are safe and effective. They're 98% effective in preventing pregnancy when used consistently and correctly. This means that 2 out of 100 couples who use condoms as their primary method of birth control will experience an unintended pregnancy in the first year. The average couple has intercourse 83 times in a year; 2 pregnancies out of 8,300 sex act is a remarkably low pregnancy rate (0.02%) when calculated on a per-condom basis. (This statistic comes from page 334 of the 18th edition of Contraceptive Technology. It was not included in subsequent editions but conversations with Lee Warner, the author of the chapter on condoms, tell us it's still accurate.)

People don't always use condoms consistently (every time they have sex) and correctly (following instructions from start to finish). Research estimates that under real-world conditions, condoms are about 87% effective in preventing pregnancy. It's important to know that this includes condoms that are used incorrectly (like putting it on too late or taking it off too early) and even includes sex acts that may not have been protected by a condom at all.

Condoms are also the only form of birth control (other than abstinence) that protects against STIs, including HIV.

Most people can use latex condoms without any side effects. A small number of people (less than 1%) may be allergic to latex. These people can use polyurethane condoms instead.

Keep your condoms in a cool, dry place. Storing them near heat (like in your glove compartment) can cause them to become brittle or gummy and no good to use. Learn more about condom care.
