They are a form of barrier contraception used to prevent pregnancy and protect against sexually transmitted infections during sexual intercourse. Condoms , when used correctly and consistently, are safe and highly effective in preventing transmission of most sexually transmitted infections, including HIV, and unplanned pregnancies. Condoms are safe, inexpensive and widely available. Condoms come in different sizes and are described with terms like "standard" and "regular" which may or may not mean the same thing. Even when a condom comes with a size chart, there can be variations between what "large" means with one brand and what "large" means with another. Wearing a condom during sex can help prevent pregnancy and the spread of sexually transmitted infections. Whether you're using a male or female condom , it's important that you put it on properly or it won't be as effective.
