Condom - GCSE Biology Definition

A condom is a thin, stretchy cover that is worn over the penis during sexual intercourse. It is usually made from latex, a type of rubber, but can also be made from other materials like polyurethane for those with latex allergies. Condoms are an important form of contraception, helping to prevent pregnancy by stopping sperm from entering the vagina. They also protect against sexually transmitted infections (STIs) by providing a barrier that prevents the exchange of body fluids. In GCSE Biology, understanding how condoms work is important when studying human reproduction and methods of preventing pregnancy and disease.
