A Warning about the Spermicide Nonoxynol-9
For years, nonoxynol-9 was thought to have beneficial effects in the battle against Sexually Transmitted Diseases (STDs). However, new research studies are leading to the opposite conclusions. A study published in March, 2002 found that the spermicide nonoxynol-9 does not protect against gonorrhea or chlamydia infection.1 Researchers have also found that it does not prevent HIV infection. Furthermore, evidence indicates that nonoxynol-9 use can cause skin irritations and tears which allow viruses, especially HIV, to be transmitted more easily.2 To minimize your risk of acquiring STDs, do not rely on spermicides for protection. Barrier methods, such as latex condoms, are a more effective means of preventing the spread of STDs.
