Condom Fact Sheet in Brief

July 7, 2010

Consistent and correct use of the male latex condom reduces the risk of sexually transmitted disease (STD) and human immunodeficiency virus (HIV) transmission. However, condom use cannot provide absolute protection against any STD. The most reliable ways to avoid transmission of STDs are to abstain from sexual activity, or to be in a long-term mutually monogamous relationship with an uninfected partner. However, many infected persons may be unaware of their infection because STDs often are asymptomatic and unrecognized.

Condom effectiveness for STD and HIV prevention has been demonstrated by both laboratory and epidemiologic studies. Evidence of condom effectiveness is also based on theoretical and empirical data regarding the transmission of different STDs, the physical properties of condoms, and the anatomic coverage or protection provided by condoms.

Laboratory studies have shown that latex condoms provide an effective barrier against even the smallest STD pathogens.

Epidemiologic studies that compare rates of HIV infection between condom users and nonusers who have HIV-infected sex partners demonstrate that consistent condom use is highly effective in preventing transmission of HIV. Similarly, epidemiologic studies have shown that condom use reduces the risk of many other STDs. However, the exact magnitude of protection has been difficult to quantify because of numerous methodological challenges inherent in studying private behaviors that cannot be directly observed or measured.

Theoretical and empirical basis for protection: Condoms can be expected to provide different levels of protection for various STDs, depending on differences in how the diseases or infections are transmitted. Male condoms may not cover all infected areas or areas that could become infected. Thus, they are likely to provide greater protection against STDs that are transmitted only by genital fluids (STDs such as gonorrhea, chlamydia, trichomoniasis, and HIV infection) than against infections that are transmitted primarily by skin-to-skin contact, which may or may not infect areas covered by a condom (STDs such as genital herpes, human papillomavirus [HPV] infection, syphilis, and chancroid).


STDs, Including HIV

HIV Infection

  • Consistent and correct use of latex condoms is highly effective in preventing sexual transmission of HIV, the virus that causes AIDS.

Other STDs and Associated Conditions

  • Consistent and correct use of latex condoms reduces the risk for many STDs that are transmitted by genital fluids (STDs such as chlamydia, gonorrhea, and trichomoniasis).
  • Consistent and correct use of latex condoms reduces the risk for genital ulcer diseases, such as genital herpes, syphilis, and chancroid, only when the infected area or site of potential exposure is protected.
  • Consistent and correct use of latex condoms may reduce the risk for genital human papillomavirus (HPV) infection and HPV-associated diseases (e.g., genital warts and cervical cancer).


Consistent and Correct Condom Use

To achieve maximum protection by using condoms, they must be used consistently and correctly.

The failure of condoms to protect against STD/HIV transmission usually results from inconsistent or incorrect use, rather than product failure.


How to Use a Condom Consistently and Correctly:

  • Use a new condom for every act of vaginal, anal and oral sex throughout the entire sex act (from start to finish).
  • Before any genital contact, put the condom on the tip of the erect penis with the rolled side out.
  • If the condom does not have a reservoir tip, pinch the tip enough to leave a half-inch space for semen to collect. Holding the tip, unroll the condom all the way to the base of the erect penis.
  • After ejaculation and before the penis gets soft, grip the rim of the condom and carefully withdraw. Then gently pull the condom off the penis, making sure that semen doesn't spill out.
  • Wrap the condom in a tissue and throw it in the trash where others won't handle it.
  • If you feel the condom break at any point during sexual activity, stop immediately, withdraw, remove the broken condom, and put on a new condom.
  • Ensure that adequate lubrication is used during vaginal and anal sex, which might require water-based lubricants. Oil-based lubricants (e.g., petroleum jelly, shortening, mineral oil, massage oils, body lotions, and cooking oil) should not be used because they can weaken latex, causing breakage.
