The sponges are inserted vaginally prior to intercourse and must be placed over the cervix to be effective. Sponges provide no protection from sexually transmitted infections. Sponges can provide contraception for multiple acts of intercourse over a 24-hour period, but cannot be reused beyond that time or once removed.[3]
