Barriers

Contraceptive Sponge

The contraceptive sponge is a circular polyurethane foam barrier that contains spermicide. The sponge is moistened with water and inserted into the vagina before sex so that it covers the cervix (the entrance to the uterus) to trap and absorb sperm.

When used consistently and correctly, 9% of women will become pregnant over the course of one year. With typical use, 16 out of 100 women will become pregnant.

The contraceptive sponge does not protect against sexually transmitted infections. Use condoms to reduce the risk of STIs.

The contraceptive sponge, sold under the brand name Today®, is available at family planning centers, drugstores, and in some supermarkets.

Diaphragm

A diaphragm is a rubber cup which is placed into a woman's vagina to prevent sperm from reaching the opening of the uterus. Spermicide is placed on the diaphragm to kill sperm and block the cervix (the entrance to the uterus). Diaphragms come in different sizes and a healthcare provider will perform measurements to determine what size is needed.

When used consistently and correctly, six percent of women will become pregnant over the course of one year. About 16 in 100 women will experience an accidental pregnancy in the first year with typical use.

The diaphragm does not protect against sexually transmitted infections. Use condoms to reduce the risk of STIs.
