New York Times report on new study:
A vaginal gel that sharply reduces a woman’s risk of infection with the AIDS virus is even more effective against genital herpes, a much more common risk for young American women, a new study has found.
In an unexpected bonus, the researchers also noted that it reduced herpes by 51 percent. In the trial, the gel was used within a few hours before and after sex. Another trial now going on is testing whether using it daily is more effective.
