Researchers at the Johns Hopkins University and ReProtect LLC have developed a gel that may help both block the spread of sexually transmitted diseases and reduce unwanted pregnancies.

The compound, known as BufferGel, is currently in advanced clinical trials for its ability to prevent pregnancy. Trials of its ability to block HIV transmission are scheduled to be under way soon.

When applied vaginally prior to intercourse, BufferGel maintains vaginal acidity at its normal levels, which can kill both sperm and many germs.

To learn more about this research, watch a short video news release on BufferGel.
