Hey Dr. Bob,

If it's been proven that oral sex can transmit HIV, why aren't there more cases considering the number of blowjobs that happen on any given night in san francisco? Also what do you think of michelle bachman?


Response from Dr. Frascino

Hello, Zack.

You are correct it is true that HIV can be transmitted via blow-jobs, but the number of actual new infections attributed to oral sex is relatively small in comparison to the number of guys getting hummers on an average night in San Francisco (or just about any other place in the world). There are a number of potential reasons for this. One is that saliva contains enzymes that partially inhibit HIV infection. In addition it's been noted that some (not all) HIV-negative men in long-term relationships with virally enhanced partners have an antibody response in their saliva that may inhibit HIV. Unprotected sex in some clinical studies evoked a salivary IgA1-mediated HIV-neutralizing response. This type of immune response has also been found in commercial sex workers in Kenya who remain HIV negative despite multiple exposures to HIV-positive clients through unprotected vaginal sex. However, despite these very helpful immune mechanisms, the bottom line remains that oral sex is not 100% safe. Finally, I should mention the ever increasing scientific evidence that proves being on effective antiretroviral therapy that drives the plasma viral load to undetectable levels very dramatically decreases the chance of HIV transmission.

As for Michele Bachmann, let's just say I wouldn't be surprised if it took her two hours to watch "60 Minutes." She seems to suffer from delusions of adequacy.

Is it ok to take GABA supplements with my meds?
