Effectiveness depends on the user: Risk of pregnancy or sexually transmitted infection (STI) is greatest when female condoms are not used with every act of sex. Few pregnancies or infections occur due to incorrect use, slips, or breaks.

Protection against pregnancy:

• As commonly used, about 21 pregnancies per 100 women using female condoms over the first year. This means that 79 of every 100 women using female condoms will not become pregnant.
• When used correctly with every act of sex, about 5 pregnancies per 100 women using female condoms over the first year.

Return of fertility after use of female condom is stopped: No delay

Protection against HIV and other STIs: Female condoms reduce the risk of infection with STIs, including HIV, when used correctly with every act of sex.
