Condom effectiveness

Condom Effectiveness

Condom effectiveness (/ˈkɒndəm ɪˈfɛktɪvnəs/), from the Latin condon meaning "receptacle", is a measure of how well condoms prevent sexually transmitted infections (STIs) and pregnancy.

Definition

Condom effectiveness is typically expressed as a percentage, with 100% effectiveness meaning no STIs or pregnancies occur during condom use. This measure is influenced by factors such as correct and consistent use, the type of condom used, and the specific sexual activity involved.

Types of Condoms

There are two main types of condoms: male condoms and female condoms. Male condoms are worn on the penis and work by catching semen and preventing it from entering the partner's body. Female condoms are inserted into the vagina or anus and work by forming a barrier that prevents semen from reaching the egg.

Factors Affecting Condom Effectiveness

Several factors can affect condom effectiveness, including:

Correct use: Condoms must be used correctly to be effective. This includes using a new condom for each act of sex, putting it on before any sexual contact, and removing it immediately after ejaculation.
Consistent use: Condoms must be used every time a person has sex to provide the best protection.
Type of sexual activity: Condoms are more effective at preventing STIs transmitted by genital fluids (such as HIV and gonorrhea) than those transmitted by skin-to-skin contact (such as herpes and HPV).
Type of condom: Some types of condoms, such as those made of latex, are more effective than others at preventing STIs and pregnancy.

Effectiveness Rates

According to the CDC, when used consistently and correctly, male condoms are 85% effective at preventing pregnancy and female condoms are 79% effective. The effectiveness at preventing STIs varies depending on the specific infection.
