A condom is a thin, flexible sheath typically made of latex, polyurethane, or polyisoprene, designed to cover the penis during sexual intercourse. Its primary purpose is to prevent pregnancy and reduce the risk of sexually transmitted infections (STIs) by acting as a barrier. Condoms are available in various sizes, textures, and flavors, and they are a widely used form of contraception. Proper use and storage are important to ensure their effectiveness.
