Using a sperm-killing product can provide added protection against pregnancy.

Spermicide, or sperm-killing products, are a barrier method of birth control. Spermicide forms are:

  • Foam
  • Cream
  • Jelly
  • Film
  • Suppository
  • Tablet

Foam spermicides bubble in the vagina. Cream, jelly, film and suppository spermicides melt in the vagina. All of them block the entrance to the uterus and kill sperm to prevent pregnancy.

How is it Used?

Spermicide products are inserted deep into the vagina before intercourse. Insertion requirements and techniques vary, so carefully read instructions for each type before use. For example, some products need to be in place for at least ten minutes before sexual intercourse begins.

Does It Protect Against STIs?

STI stands for sexually transmitted infection. STI risk varies depending on how you choose to protect yourself and your partner during sexual or intimate activities.

Spermicides may kill some STI germs but do not reliably protect against STIs.

Does It Protect Against Pregnancy?

Yes, spermicide does protect against pregnancy. The chances of getting pregnant while using spermicide are:

  • Typical use: 26 percent
  • Perfect use: 6 percent

Advantages and Disadvantages

Advantages:

  • Spermicide is easy to get and can be purchased in drugstores and supermarkets.
  • No prescription or fitting is required.
  • Insertion of spermicide is easy once you learn the correct technique.

Disadvantages:

  • Spermicide must be used correctly (read and follow the directions!) to be effective at pregnancy prevention.
  • Some spermicides may leak or be messy.
  • A particular spermicide may irritate the vagina or penis. Changing brands may fix the problem.
  • Spermicide must be used soon before intercourse, interrupting spontaneity.

Things to Remember

  • Spermicide does not protect against STIs.
  • Spermicide does protect against pregnancy.
  • Always read the instructions and follow them carefully.
