A spermicide is a chemical product used for birth control. It contains chemicals that kill sperm. It comes in a number of forms, such as foams, jellies, and creams. A spermicide is inserted into a woman's vagina before sexual intercourse. It destroys the sperm in a man's semen before the sperm reach the uterus.
Spermicides are somewhat unreliable when used alone to prevent pregnancy.
They are much more effective when they are used with another barrier contraceptive such as a diaphragm, cervical cap, or condom. No more than 30 minutes before sexual intercourse, use the applicator provided with the spermicide to insert spermicide high in the vagina over the cervix. The spermicide should cover the cervix. Insert more spermicide each time you have intercourse. DO NOT wash away the spermicide or douche for at least 6 to 8 hours after sexual intercourse.
