DEAR DR. ROACH: I read that condoms have tiny holes in them, and that they dont provide protection against HIV/AIDS. Is this true? — G.D.M.
ANSWER: Condoms do have tiny holes in them if magnified enough; however, latex condoms are effective at preventing HIV transmission, both measured in a laboratory as well as in clinical studies. In couples who use condoms 100 percent of the time, HIV transmission is reduced by at least 90 to 95 percent.
