The contraceptive sponge combines barrier and spermicidal methods to prevent conception. Sponges work in two ways. First, the sponge is inserted into the vagina, so it can cover the cervix and prevent any sperm from entering the uterus. Secondly, the sponge contains spermicide.[2]
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]
