What are vaginal spermicides?
Vaginal spermicides are put in the vagina before sex to help prevent pregnancy. They contain an ingredient (nonoxynol-9) that kills sperm. When sperm comes in contact with a spermicide, the sperm dies and a woman can’t get pregnant.
Spermicides are available as a jelly, foam, cream, suppositories, and film. In Canada, the only contraceptive jelly available is Contragel. Contragel is a lactic acid buffering gel, however, it is not as effective as nonoxynol-9. Lactic acid buffering gel is different than the spermicides described in this information sheet. Spermicides are considered to be among the least effective of all birth control methods.
