Your Guide to Birth Control: Condoms

Birth control is a way for men and women to prevent pregnancy. There are many different methods of birth control; some types also protect against sexually transmitted diseases . Condoms are one type of birth control that in addition to preventing pregnancy also prevent the spread of STDs.

There are two types of condoms, the male condom and the female condom.

What Is a Male Condom?

The male condom, or "rubber," is a thin covering made of latex, plastic, or animal membrane that is rolled over an erect penis. The covering prevents semen, the fluid that contains sperm, from entering a woman's vagina.

What Are Male Condoms Made of?

Most condoms are made of a type of rubber called "latex." Recently, condoms made of polyurethane (a type of plastic) have become available. These are more expensive than latex condoms and seem to break more easily. They are mainly useful for people who are allergic to latex. There are also "natural" condoms, which are made of animal membranes. These are expensive and probably not effective in preventing the spread of sexually transmitted diseases.

What Types of Latex Condoms Are There?

Condoms come in all shapes, sizes, and materials. Here are some characteristics to consider when buying condoms.

  • Size. The standard size will fit most men. Extra-large condoms are available, as well as "snug" sizes that are a little smaller and fit tighter than the standard size.
  • Shape. Some condoms come with a nipple in the end to hold the fluid when the man ejaculates. Others have a rounded end.
  • Thickness. Extra-strength condoms are available. These are stronger and are especially useful for rectal sex and for men who have problems with condom breakage. Extra thin condoms also are available, but these are not recommended because they may break more easily.
  • Lubrication. Many condoms come pre-lubricated with a substance that kills sperm (spermicide) and many disease-causing germs. Lubrication may give some extra protection, especially if the condom breaks. Lubricated condoms taste bad and are not recommended for oral sex.
  • Flavored. These condoms are meant for the male to wear when receiving oral sex. They are not lubricated and have a mild flavor (usually mint).
  • Color. Condoms come in many colors. The color of the condom doesn't make it any more or less effective.

What is hepatitis C?

Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body, and infection with HCV usually becomes chronic. Over decades, chronic infection with HCV damages the liver and can cause liver failure in some people. In the U.S., the number of new cases of infection with HCV has declined over the last 10 years from a peak of some 200,000 annually to about 19,000 in 2006. When the virus first enters the body, there usually are no symptoms, so these numbers are estimates. Up to 85% of newly infected people fail to clear the virus and become chronically infected. In the U.S., more than three million people are chronically infected with HCV. Infection is most common among people who are 40 to 60 years of age, reflecting the high rates of infection in the 1970s and 1980s. There are 8,000 to 10,000 deaths each year in the U.S. related to ...
