There has been a great deal of discussion here of late concerning the STD risk - and in particular the risk of HIV infection - associated with oral sex. I would like to share with the providers and hobbyists on this discussion board some of the information I researched last night concerning this issue.
First, I would like to provide some historical background on this subject. The current CDC recommendations concerning the risk of oral sex - specifically receptive fellatio with ejaculation into the oral cavity - is based upon data coming out of the CDC Options project in 1999[1] and presented at the 7th Conference on Retroviruses and Opportunistic Infections in San Francisco in early 2000[2] This study found an 8% infection rate among HIV negative men having receptive fellatio with ejaculation with an HIV-infected male partner. The numbers presented in this data were very small (8 newly
infected men out of 102 previously HIV-negative men in the study group).[1][2] Nevertheless, this data, together with the Rotherberg study[7] has provided the basis for virtually all recommendations concerning risk of transmission of HIV through oral sex, and also appears to be the basis for many of the current recommendations for anti-viral PEP therapy (Post-exposure prophylaxis) for mucosal contact or contamination.[3-6]
There are a number of serious deficiencies in the CDC options project data and the current CDC recommendations that may not be common knowledge to the participants on this forum:
1) First, the Project sample size was too small for statistical significance.
2) Second, a later study analysing the CDC data determined that "...at least half of these subjects (sero-positive converters) had also engaged in unprotected anal sex..."[8]
3) Third, The CDC Options Project data has NEVER been published in peer-reviewed journal. Depending upon whom you want to believe this is either because the CDC has chosen not to submit the project for publication, or that it has been submitted AND REJECTED for publication because of the serious flaws in the study design.
4) Fourth, the current CDC recomendations on this issue improperly cite medical literature as supporting their recommendations, when in fact, most of this literature draws NO conclusions concerning the risk of HIV transmission through
oral sex or has NO ACTUAL DATA addressing the risk.[10-16]
5) The current CDC recommendations OMIT current peer-reviewed literature that contradicts the CDC Options Project data or current CDC recommendations.[17-20]
At the International AIDS Conference in Barcelona last year, two peer-reviewed and well designed studies were presented that specifically addressed the risk of HIV transmission through orogenital sex. The first study[19] was a 10-year study of oral sex between an infected partner and a non-infected partner. This study documented 210 person-years of patient followup, nearly 19,000 episodes of unprotected fellatio with over 1/3 of those episodes resulting in ejaculation into the mouth. This study found a ZERO incidence of HIV concersion in the uninfected partner. The authors of this first study concluded HIV that "...this seems to point to a very low probability of HIV transmission related to this practice, when other risk exposures are excluded...."
The second study was a smaller but statistically significant study out of San Franciso[20] which also found no sero-conversion to HIV from receptive fellatio with a 39% ejaculation rate into the mouth of the non-infected partner over a 2-year study period. The conclusion of this study is as follows: "It is important that health professionals, including HIV counselors have valid information to impart to their sexually active clients. If individuals believe that the risk of HIV from fellatio is high or on a par with well-documented
high-risk exposures such as anogenital sex, they may not feel that sexual behavior choices make a difference. Acquiring HIV through fellatio is significantly less risky than from anal sex, and therefore one's choice of sexual practices do matter."
Finally, this forum's participants should be aware that the current Bush administration has altered two online health fact sheets: The first is the CDC online fact sheet concerning condom use and STI (STD) prevention. The second sheet is on the National Cancer Institute (NCI) website and addresses studies discussing link between abortion and breast cancer. Fourteen House Democrats, led by Henry Waxman (D-CA), have sent a letter to Health and Human Services Secretary Tommy Thompson expressing their outrage that the White House is pushing its political agenda (Bush's agenda on abstinence-only education) into the realm of scientific fact. Whatever the reasons, the changes to these two fact sheets have been made arbitrarily and in contradiction to the existing scientific literature on both subjects.[21]
Massage, spin, manipulation, and even outright prevarication are unfortunately all-to-common practices in the scientific literature of late - whether one is attempting to fly their personal, political, or corporate agenda on their right wing, their left wing, or their economic wing. It appears that the CDC is not immune from this "spin-doctoring" and can no longer be relied upon to provide impartial and dispassionate advice on those issues of personal health and sexuality that conflict with the current administration's political agenda.
I do not suggest that providers (who are most at risk of HIV transmission from oral sex) change the practices they are comfortable with concerning CBJ versus BBBJ. There is plenty of evidence that HIV transmission is possible through oral-genital contact. But that evidence points to an extremely small incidence.
I do suggest that both providers and hobbyists exercise caution and a healthy dose of skepticism when relying upon the recommendations of CDC on any issues of sexuality. It has become obvious to me that the CDC is no longer immune from
the politics involved in sexual activity.
