The contraceptive sponge is a round piece of white plastic foam. It has a dimple on one side and a nylon loop across the top. It is 5 cm across, and you insert it into your vagina before you have intercourse. The sponge works in two ways: it keeps sperm from getting into your uterus by blocking your cervix, and also continuously releases spermicide. The sponge needs to be completely wet to activate the spermicide. Make sure to squeeze it to distribute the water.
