Why do I need to use a Condom?



Condoms are the only form of protection which can both help to stop the transmission of sexually transmitted diseases (STDs) such as HIV and prevent pregnancy. A number of different types of condoms are now available. What is generally called a condom is the 'male' condom, a sheath or covering which fits over a man's penis, and which is closed at one end.

What are Condoms made of?

Condoms are usually made of latex or polyurethane. If possible you should use a latex condom, as they are slightly more reliable, and in most countries they are most readily available. Latex condoms can only be used with water based lubricants, not oil based lubricants such as Vaseline as they break down the latex. A small number of people can have an allergic reaction to latex and can only use polyurethane condoms instead. Polyurethane condoms are made out of a type of plastic. They are thinner than latex condoms, and so they increase sensitivity and are more agreeable in feel and appearance to some users. They are more expensive than latex condoms and slightly less flexible so more lubrication may be needed. However both oil and water based lubricants can be used with them.

What about the condom size?

Condoms are made in different lengths and widths, and different manufacturers produce varying sizes. There is no standard length for condoms, though those made from natural rubber will in addition always stretch if necessary to fit the length of the man's erect penis. The width of a condom can also vary. Some condoms have a slightly smaller width to give a "closer" fit, whereas others will be slightly larger. Condom manufacturers have realised that different lengths and widths are needed and are increasingly broadening their range of sizes.

Is using a condom effective?

If used properly, a condom is very effective at reducing the risk of being infected with HIV during sexual intercourse. Using a condom also provides protection against other sexually transmitted diseases, and protection against pregnancy. In the laboratory, latex condoms are very effective at blocking transmission of HIV because the pores in latex condoms are too small to allow the virus to pass through. However, outside of the laboratory condoms are not always 100 safe. But you are certainly a lot safer with condoms than you are without.
