Spermicides
Effectiveness: 71 to 82 percent. (15-29 pregnancies per 100 women each year; when used alone, spermicide is not very effective, but it increases the effectiveness of other barrier methods of contraception).
What is it? Spermicides are chemicals, primarily Nonoxynol-9, that kill sperm. They come in the form of foam, gel, cream, suppository or vaginal contraceptive film.
How does it work? The spermicide chemicals (usually Nonoxynol-9) are inserted deep in the vagina before sex. They block the cervix and stop the sperm from moving, which prevents fertilization of an egg. Follow the product instructions. In general terms, you insert the foam, gel, cream, suppository or vaginal contraceptive film into your vagina, over the cervix. Insert 10 minutes to one hour before intercourse (follow package instructions) and repeat each time you have intercourse. Do not douche for at least 6 to 8 hours after intercourse. Spermicides are more effective when used with a condom, diaphragm or cervical cap.
STD protection: No; you will still need to use condoms if you are concerned about STDs.
