Sexual Health - STD / AIDS
- Birth Control Options - Contraceptive Sponge

Contraceptive Sponge

The contraceptive sponge is a disposable, soft foam sponge containing spermicide. It is placed into the vagina before sex to prevent pregnancy.




How does it work?


The sponge is placed inside the vagina, over the cervix, where it acts as a barrier and a spermicide. The sponge traps and absorbs the sperm, where they are then disabled by the spermicide. It is effective for up to 12 hours.




How effective is it in preventing pregnancy?

  • For women who have never given birth, the sponge is 91% effective in preventing pregnancy with perfect use. (84% effective with typical use)

  • For women who have previously given birth, the sponge is only 80% effective with perfect use. (68% effective with typical use)




What are the advantages?

  • Does not contain hormones

  • Can be used by women who smoke or are breastfeeding

  • Provides 12 hour protection

  • Do not need to change the sponge if sex is repeated during the 12 hour time frame

  • Can be used in combination with a male condom to increase contraceptive effectiveness and protection against sexually transmitted infections.

  • Widely available in stores without a prescription




What are the disadvantages?

  • Does not protect against sexually transmitted infections.

  • Some women may find it difficult to remove the sponge, or may forget to remove it altogether

  • If the sponge is left in the vagina for too long, symptoms of toxic shock syndrome may appear

  • May cause vaginal irritation or infection

  • Cannot be used by people who are allergic to spermicides
