A condom is a device, usually made of latex, or more recently polyurethane, that is used during sexual intercourse. It is put on the male partner's penis, for the purpose of preventing pregnancy and/or transmission of sexually transmitted diseases (STDs) such as gonorrhea, syphilis and HIV. It was invented in Europe by an unknown inventor.
Condoms are also known as prophylactics, as well as a number of colloquial or slang terms, such as "rubbers", "jimmy hats", "rain coats" and "love gloves". They are also sometimes used to increase pleasure by those who prefer the sensation of sex with condoms.
Duron/Polyurethane versus latex
Advantages:Polyurethane can be considered better than latex in several ways:
It conducts heat better than latex
It lasts longer in storage
It does not degrade in oil-based lubricants, also it does not degrade as readily as latex
It is suitable for those with latex allergies. Polyurethane is widely used in internal medicine such as artificial hearts, pumps, and blood vessel catheters.
Polyurethane condoms have no smell, unlike latex condoms
Polyurethane condoms are smoother than latex ones
Unlike latex condoms, which must be stored at a reduced temperature range to avoid degradation, polyurethane condoms have no such requirements.
Disadvantages:
Clinical failure (breaks and slippage, together) of polyurethane show significantly higher rates over latex use.
It is more expensive than standard latex condoms.
It may not be as effective in protecting against STDs. This uncertainty comes from lack of testing.
Proper use and condom failure
Condom failure rates can vary depending on usage. People who use condoms "perfectly" have a failure rate of 3%. Typical usage of condoms (mistakes in application, failure to use them every time, and other failures to follow the directions) can bring the failure rate up to 15%.
Most condom failures are due to misuse. This has led some researchers to suggest age-appropriate sex education that includes how to use a condom properly.
The packaging often contains instructions for use, and often suggests lubricants. For more specific information, advice on condom use, and a visual guide to use, please see Use of male condoms.
Another possible cause of condom failure is sabotage. One motive is to have a child against a partner's wishes, known to be done by men and women alike. Saboteurs usually pierce the condom's tip multiple times before intercourse. As this can result in pregnancies unwanted by one of the participants, it is generally seen as a deceitful and unethical act.
Recently, condom manufacturers are becoming aware that "one size does not fit all". Improper fit of condom to penis is being cited as a risk for condom slippage, breaking, and leakage.
