Contraceptive Sponge What is it? A soft, disposable, non-latex foam (polyurethane) device that is placed in the vagina before sex. The sponge contains a spermicide, which blocks or kills sperm. How does it work? • Fits over the cervix (entrance to uterus) • Traps, absorbs, and weakens the sperm (male reproductive cells) • Works for up to 12 hours Advantages • Does not contain hormones • Can be used by women who are breastfeeding • Can be used by women who smoke • One size fits all women • Does not require a prescription • Can be used for multiple acts of sex within a 12 hour time period Considerations • Must be available at the time of sex • Must be left in place for six hours following sex but no longer than 12 hours • Must be put in correctly • May irritate the vagina, which may increase the risk for contracting human immunodeficiency virus (HIV) • Cannot be used by people who are allergic to spermicides • If left in the vagina longer than the recommended time, symptoms of toxic shock syndrome may occur (fever, shock, problems with body organs) How to use the sponge Insert into the vagina at least 15 minutes prior to sex. Make sure to follow package instructions. Typical success rate Successful for 6.8 to 8.4 people out of 10.
