Yes. The menses would contain blood cells from systemic circulation, which would include CD4+ T-cells.

Yeah, there's lots of good content in there, not aware of any really good recent studies

Yes, I have heard many doctors use phrases like "no risk" or "theoretical risk only" with DATY. If there was profuse vaginal bleeding or discharge (perhaps associated with menses) and you were giving oral and had cuts in your mouth... *maybe*, but that's stretching a lot...

STD Risk Calculator lists these studies on their references for how they do the oral sex HIV transmission figures http://www.ncbi.nlm.nih.gov/pubmed/20543603 http://www.ncbi.nlm.nih.gov/pubmed/19179227

I read a review published about 10 years ago on oral transmission of HIV. That review references the Vittinghoff study. Actually, if you go to page 3 of this thread, and look at the images I posted, you can see the results of that study, I highlighted them with red.

To answer your question, yes, it's quite low. The reason we talk a lot about stats that come from studies involving gay men, is because the prevalence of HIV is higher for gay men. In other words, about 20% of gay men have HIV, and about 1% of straight men have HIV. Statistics change a bit from...

This part is a bit difficult because many such men still occasionally do anal intercourse... Did you have a particular study in mind from what you wrote?

Well, it's an interesting point actually. The standard HIV test actually checks for antibodies (made by our bodies) in response to the infection, so this test could easily be fooled, if the antibodies were present for some reason, or if there was cross-reactivity with antibodies for another...

Looks like fuji is actually the one who "ran away"

Funny thing these rumors are! I've done an HIV PCR myself. The virus has been sequenced, you can read the genome (and all the genes and proteins) online if you want. So anyone can directly observe evidence of existence of the virus. So fair to say that, at least in my experience, it exists...

So, STD Risk Calculator is pretty much exactly right with their article on HIV transmission that quotes the 1 in 10,000 figure... By the way, there's piles more research papers, but I figured that: (a) a couple dozen confirmed case reports from independent sources, (b) a list of studies showing...

Here are some studies that found statistically significant risk of transmission for oral sex and HIV. Here is UpToDate's answer, which is a clinic tool used by doctors the world over:

You are foolish. Let me emphasize, it is very difficult to get clean research on this issue because very few people only do oral sex and totally abstain from vaginal/anal sex for long periods of time (i.e. years). You need a population like that to properly find out what the risk of HIV...

Here is a classic Letter to the Editor, from several well respected physicians printed in one of the most respected medical journals in the world, the Lancet.

Here's a source, which includes full references: STD Risk Calculator - HIV Transmission

I am not "fear-mongering". You are just reacting to new information that affects you because of your lifestyle. Sorry that I have shaken your worldview.

You say I "ran away", but actually I am here talking to you. No need to be so rude. I will reply with references.

I stand by that remark. The risk of infection is your main risk because the severity of the outcome is so much greater than a gonorrhea infection, despite the odds being lower. In medicine, Risk = (Severity of Outcome)x(Probability of Event) Review this concept here...

What's your problem exactly? The same CDC source I just showed you confirms what you are saying, which is that a very significant among of HIV infections are among the MSM population (which includes gay men) and among injection-drug users. This doesn't change the fact that HIV is also...

Yeah, I will qualify that remark. Risk is very very low. Generally when you talk about getting HIV from oral sex, the risk is to the person who gives oral sex to a man. Precum can contain HIV, although the saliva has enzymes that rapidly deactivate it. Ejaculate (i.e. semen/cum) can be loaded...
