Contraceptive sponge is a combined 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 is produced with spermicide already inside of it, which is used to prevent the sperm from moving.

Sponges are a physical barrier, trapping sperm and preventing their passage through the cervix into the female reproductive system. The spermicide is an important component of pregnancy prevention; each brand offers a different formula.

Some sponge must be run under water until thoroughly wet, about 2 tablespoons of water is needed. The water is used as a mechanism to activate the spermicide inside the sponge and No extra spermicide is needed. While some Sponges already comes ready to use.

The sponges are inserted into vagina prior to intercourse and must be placed over the cervix to be effective. The sponge can be inserted up to 24 hours before intercourse. It must be left in place for at least six hours after intercourse. It should not be worn for more than 30 hours in a row. Sponge should never be reused once it has been removed.

Sponges provide no form of protection from sexually transmitted infections (STIs).
