Spermicide

What is it?
Spermicide is a reversible barrier method of birth control. It is available in a variety of contraceptive preparations, including foams, creams, jellies, film, and suppositories, which are liquids or solids that melt after they are inserted. These products are inserted deep into the vagina shortly before intercourse. The chemical spermicide that they contain immobilizes sperm, preventing it from joining with an egg.

Contraceptive foams, creams, jellies, film, or suppositories usually require waiting 10 minutes after insertion before intercourse can begin. These methods typically only remain effective for one hour after insertion. More spermicide must be inserted each time vaginal intercourse is repeated.

Detailed instructions for correct use are included in the packaging. Be sure to read and understand them before you use any of these products.
