A condom is a material which can be used during oral, anal and/or vaginal sex to create a physical barrier that significantly decreases the probability of pregnancy and of contracting some (but not all) Sexually Transmitted Infections (STIs). There are two main types of condoms, male (designed to cover the penis) and female (designed to cover the inside of the vagina). Condoms are usually made of latex or nitrile rubber, and come in a range of colors, flavors, textures and sizes. With ‘perfect’ use (using a new condom each time, placing and removing it correctly, using only water-based lubricants, and using them consistently) male condoms are successful at preventing pregnancy 98% of the time. With correct and consistent use female condoms are 95% effective at preventing pregnancy. Importantly, even with correct and consistent use condoms cannot completely remove the risk of pregnancy or contracting an STI.
