Final answer:
The female condom is a barrier contraceptive that prevents sperm from entering the vagina and also helps in preventing sexually transmitted infections (STIs), with a typical use failure rate of 21 percent.
Step-by-step explanation:
An accurate description of the female condom is that it is a barrier method of birth control designed to prevent sperm from entering the vagina during sexual intercourse. Unlike barrier methods such as diaphragms or cervical caps, female condoms also help to prevent the spread of sexually transmitted infections (STIs). With typical use, female condoms have a failure rate of about 21 percent. It is important to note that female condoms are distinct from male condoms, which have a typical use failure rate of 18 percent. Like male condoms, female condoms are intended for single use and should be disposed of after one sexual encounter. Compliance with proper usage is crucial for maximizing effectiveness in preventing pregnancy and reducing the risk of transmitting STIs.
