Spermicide is a liquid, gel, foam, capsule or film that is made from a substance called nonoxynol 9. This chemical kills sperm and is present in most condoms and the sponge. It is also used with a diaphragm to make it a more effective birth control. It can be purchased over-the-counter without a prescription where condoms are sold. If spermicide is used EVERY TIME you have sex it is 85% effective. This is not a great method of birth control when used by itself.
