How effective is the female condom at preventing sexually transmitted diseases, including HIV?
The ability of the female condom to prevent the transmission of HIV and other sexual diseases is speculative, but promising. Laboratory studies have found that the female condom is impermeable to various STD organisms, including HIV. Only one study involving human use has been done to evaluate its STD prevention properties. Among 20 women with recurrent vaginal trichomoniasis, none of them experienced reinfections while using the device consistently and correctly.
