BELGIUM, May 14, 2002 ( – In a significant setback in the battle against HIV/AIDS, the controversial spermicide nonoxynol-9 has been found to be ineffective. According to Wired News today: “The first-ever meta-analysis of studies on the protective benefits of nonoxynol-9 against HIV and other sexually transmitted diseases found that the spermicide offered no significant protection against any such infections, said David Wilkinson, a professor of rural health at the University of South Australia in Adelaide who conducted the analysis.”  Condom manufacturers say nonoxynol-9 is contained in 45% of condoms sold commercially. It supposedly makes them more effective, but not without side-effects. The latest study also reports that the spermicide increases the risk of genital lesions, Trichomonas, parasites that are frequently sexually transmitted, and bacterial vaginosis, a common vaginal infection.  According to Wired News, this new analysis confirms the results of a 2000 study that showed that nonoxynol-9 offered no protection against HIV. At the same time, however, it does not back up the observations from the earlier study that the spermicide increases the risk of HIV infection. Prof. Wilkinson said that since most of the women in the studies were commercial sex workers who used nonoxynol-9 multiple times daily, he hoped the risks associated with its use would be much lower for women who use it less frequently.  See:,1286,52481,00.html
