The birth control sponge is a soft, squishy sponge that is worn deep inside the vagina during sex.
How does it work to prevent pregnancy?
Spermicide (sperm-killing medicine) in the sponge kills the sperm, and the egg is not fertilized. The sponge also absorbs semen and sperm and physically blocks the cervix. To be effective, it must be left in the vagina for at least 6 hours after intercourse.
How effective is it in preventing pregnancy?
14 to 22 out of 100 couples will get pregnant in the first year. People who already given birth have a higher chance of pregnancy with the sponge. It may be that the sponge can cover the cervix better if the person has not yet delivered a child.
How effective is it in preventing STDs?
The sponge does NOT protect against STDs! In fact, the sponge may actually increase your risk for HIV and other STDs – the spermicide in the sponge can irritate your vagina, making it easier for STDs to enter your body. To reduce your risk of STDs (and pregnancy) use condoms.
