Condoms are the only type of contraception that can both prevent pregnancy and protect against sexually transmitted infections (STIs).
There are two types of condoms: male condoms, worn on the penis and female condoms, worn inside the vagina.
Male condoms are made from very thin latex (rubber), polyisoprene or polyurethane and are designed to stop a man's semen from coming into contact with his sexual partner.
When used correctly every time you have sex, male condoms are 98% effective. This means two out of 100 women will become pregnant in one year when male condoms are used as contraception. They can also protect against STIs if used correctly during vaginal, anal and oral sex.
