Birth Control - Spermicide:
Spermicide kills or disables sperm so that it cannot cause pregnancy. Spermicide comes in many different forms: foam, jelly, cream, film, and suppositories. Most use the chemical nonoxynol-9 against sperm. Spermicide provides lubrication and can be used with other methods of birth control. They are most effective when used consistently and correctly with a barrier method of birth control, like a condom. Spermicide is 71-82% effective as birth control. Used alone, Spermicide does not protect against HIV/AIDS.
