Spermicide

The facts: Spermicide is a birth control method that a woman inserts into her vagina before sex. It's a gel, foam, cream, film, suppository or tablet, in different doses and concentrations, that kills the sperm. This method provides only limited, if any, protection from HIV and other sexually transmitted diseases.

How well it works: About 74 percent effective in preventing pregnancy with typical use and up to 94 percent effective with perfect use.

Pros:
• Does not contain hormones.
• Does not require direct involvement of the male partner and does not interrupt lovemaking.
• Available without a prescription in most drug stores.

Cons:
• Provides only limited, if any, protection from HIV and other sexually transmitted diseases.
• Not as effective in preventing pregnancy as other birth control methods, such as the male condom, the birth control pill or the shot.
• Side effects may include increased urinary tract infections or irritation.

Where to get it: Spermicides are available without a prescription at most drug stores.

Cost: Tubes of spermicidal creams, jellies and foam and packages of suppositories cost from $8 to $17. Medicaid and some private health insurance plans may cover most or some of these costs. Many family planning clinics provide services and supplies free or on a sliding scale, based on your income.
