A condom is a barrier method of contraception which can be used to prevent pregnancy and reduce the transmission of sexually transmitted infections (STIs). It is a sheath made of latex or polyurethane which is worn over the penis during sexual intercourse. In contraception the condom acts as a barrier, preventing semen from entering the vagina. For STI prevention a condom helps block the exchange of bodily fluids that can transmit infections.
Condoms are available in various sizes and styles, including lubricated and non-lubricated, and with or without added features such as textures or flavours. To use a condom, the tip is squeezed to remove any air and then the condom is rolled onto the erect penis, making sure there are no tears or defects. After ejaculation, the condom is removed and then thrown away.
It is important to use a new condom with every act of intercourse and to store condoms in a cool, dry place to prevent damage. Regular use of condoms can provide effective protection against pregnancy and STIs.
