However, most condoms are a dull translucent tan color. History of the Condom Condoms have actually been used for centuries. Latex condoms have been available since the 1930s, but in most parts of the world they have never been widely used. However, in the 80s, the worldwide epidemic of STIs, including HIV, prompted renewed interest in latex condoms which, to date, remain the most effective method of preventing disease transmission during intercourse. They protect partners during vaginal and anal intercourse as well as oral sex.
Condoms help prevent pregnancy by keeping the sperm from entering the vagina.
When used correctly and consistently, condoms are an effective means of preventing pregnancy. Pregnancy rates range from about three percent to 14 percent. This means 3 to 14 out of 100 women become pregnant in a year using only condoms for contraception. However, these 3 to 14 pregnancies are usually not due to condom failure. Because latex condoms block exchange of body fluids, they offer better protection against STIs than any other birth control method.
