What is it?
A contraceptive sponge is a disposable foam device that you insert into the vagina. You do not need to see a health-care provider for insertion, as you can insert the Sponge by yourself. The Sponge is available at pharmacies without a prescription.
How does it work?
- The Sponge fits over the cervix and creates a barrier to prevent sperm from entering.
- It contains spermicide, which can damage or destroy sperm.
- Once inserted, the Sponge begins working immediately.
- It should remain in the vagina for six hours after sex but no longer than 30 hours.
- Use the Sponge every time you have sex.
Is it effective?
The Sponge is among the least effective forms of birth control.
- The Sponge is approximately 86% effective in preventing pregnancy for people who have not given birth.
- This means that 14 out of 100 sponge users who have not given birth will get pregnant in a year.
- It is 78 % effective in people who have given birth.
- This means that 22 out of 100 sponge users who have given birth will get pregnant within a year.
