There have been setbacks in the development of a gel spiked with tenofovir -- a microbicide that can be used vaginally or anally to prevent HIV. The CAPRISA study, unveiled to much fanfare in 2010, found such a gel worked pretty well in women. But this year, another study called VOICE was partly cancelled after researchers discovered that one of the gels it was testing failed to prevent infection. Scientists are unsure why the latest trial was unsuccessful.

Meanwhile, researchers are conducting trials of an antiretroviral-containing vaginal ring that potentially could "prove to be more effective and easier to use than" microbicides. And earlier this year, scientists announced that they had successfully pilot-tested an anal microbicide gel. The risk of HIV infection is up to "2,000 times greater with receptive anal sex than vaginal sex" they said, so the potential there could be huge.
