A barrier method of birth control containing a sperm-killing product. Spermicides are available in foam, cream, jelly, film, suppository or tablet form.

• Foam: prevents pregnancy by bubbling within the vagina, blocking the entrance to the uterus and killing sperm.
  
• Cream, Film, Jelly and Suppositories: prevent pregnancy by melting in the vagina, blocking the entrance to the uterus and killing sperm.

How is it used?

• The spermicide products are inserted deep into the vagina before intercourse.
  
• The instructions for each different form of spermicide must be read and followed before use, as the insertion requirements and techniques vary (for example, some products need to be in place for ten minutes before sexual intercourse begins).
