However, clinical studies of humans in real life settings have been inconclusive as to N-9's efficiency and safety. They asked 1000 HIV-negative prostitutes in several African countries to use a gel along with condoms for intercourse. Half of the women were given a gel containing no spermicide, while half were given a gel containing N-9. Keep in mind that this is only one study and more research will be done. The CDC has accelerated its efforts to identify a safe and effective alternative to N-9.
Sex is something that can be a health risk under some circumstances.
According to the Department of Health and Human Services, more than 7,000 new HIV infections occur in the world each day. Nonoxynol-9 has been counted on to offer some measure of protection. Now that its effectiveness and safety are in question, sex has become less safe. There are no other alternatives to rely on. Being educated about the risks that come from sex and choosing partners carefully is a way to be more careful that not.
