The world's most widely used spermicide does not kill the bacteria that cause gonorrhea and chlamydia, according to a new report.
Nonoxynol-9 is marketed for birth control, not disease prevention. But it has been shown in laboratory tests to act against some pathogens, including those that cause gonorrhea and chlamydia, leading to speculation
that it might have wider application
Researchers conducted a trial to compare nonoxynol-9 gel and condom use against condom use alone to prevent male-to-female transmission of the two STDs. "Nonoxynol-9 gel did not protect against
urogenital gonococcal or chlamydia infection," concluded the report.
An earlier round of research, also found the agent does not kill HIV.
