Contraceptive Sponge

The contraceptive sponge is a soft saucer-shaped device made from polyurethane foam. It is considered a barrier method of birth control.

How does a birth control sponge work?

It is designed to fit over the cervix and works in three ways to prevent pregnancy:

  • It blocks the cervix, preventing semen from entering the uterus.
  • The sponge contains spermicide which kills sperm.
  • The sponge absorbs the semen.

How effective is a contraceptive sponge?

When is used correctly and consistently, it has about a 9% failure rate or almost 1 in 10. The typical use of the contraceptive sponge refers to the way that most people use it. The failure rate during typical use is approximately 16%. You should take a pregnancy test if you are experiencing any pregnancy symptoms.

What are the side effects or health risks of a contraceptive sponge?

The sponge has been associated with some women experiencing toxic shock syndrome (TSS) – a rare but serious life-threatening bacterial infection.
The sponge should not be left inside the vagina for more than 30 hours. The sponge should not be used during menstruation or if you have a history of TSS.

Is a birth control sponge reversible?

Yes. It does not have any effects on either the male’s or female’s reproductive function. Pregnancy is possible when you stop using it.

What about sexually transmitted diseases (STDs)?

It does NOT provide protection against the transmission of sexually transmitted diseases.
