What is the sponge? The birth control sponge (aka the contraceptive sponge or âthe spongeâ for short), is a small, round sponge made from soft, squishy plastic. You put it deep inside your vagina before sex. The sponge covers your cervix and contains spermicide to help prevent pregnancy. Each sponge has a fabric loop attached to it to make it easier to take out. The only brand of sponge sold in the U.S. is the Today Sponge. How does the sponge work? The sponge prevents pregnancy two ways: It fits snugly against your cervix, blocking the entrance to your uterus so sperm canât get to your egg. The sponge also contains spermicide, which slows sperm down so it canât reach your egg. The sponge can be used by itself, or with condoms.
