Can I get HIV through oral sex? is probably one of the most frequent questions we get asked at Freedomhealth either in person or via our Sexual Health Forum. The answer is yes, possibly, but it is exceptionally unlikely.我能通过口交得艾滋吗？这是在Freedomhealth和其他健康论坛里被问的最多的问题之一。答案是，是得，也许，但是这种情况极其的不可能。
There has been a great deal of interest and many research papers written about the HIV risks associated with oral sex and similarly many studies to try to determine why the risk of oral sex with an HIV positive person might be less than that associated with unprotected penetrative vaginal or anal sex.有很多关于口交和HIV传染风险的文章，这些文章和许多尝试去解开为什么口交传染HIV的风险比无套肛交和性jiao的研究一样，
Romero and others, in their article describing an excellent and diligent long term study failed to identify any risk at all in transfer of HIV from an HIV positive to an HIV negative partner through oral sex. In total 19000 episodes of oral sex were documented amongst 135 heterosexual couples over ten years and in 34% of these episodes the HIV positive male ejaculated into the HIV negative females' mouth. (Romero J et al. Evaluating the risk of HIV transmission through unprotected orogential sex. AIDS 16:9:1269-97, 2002.) 在西班牙和其他国家的长期、严格控制的研究中，通过135对一方HIV阳性一方阴性的异性恋伴侣长达10年的1.9万次无保护口交来证明感染HIV的风险，34%阳性的人有口腔内射的习惯，没有人感染。
Baggaley and others, in their article Systematic review of orogenital HIV-1 transmission probabilities. International Journal of Epidemiology 37 : 1255-65, 2008 have reviewed the major articles to date and conclude that the risks of HIV transmission via oral sex are low.BAGGALEY和他的伙伴，在论文中回顾了以往关于口交传染HIV的研究，得出结论，通过口交传染HIV的风险很低。
To reach their conclusions they conducted a systematic review of the available literature. Ten studies from North America and Europe were identified as meeting the required criteria.为了得到这一结论，他们查阅了很多有价值的文献，10份来自于北非和欧洲的研究被认为符合标准。
The authors noted some difficulties with the methodology of the studies。 These were mainly the common ones of:-作者指出一些困难的和研究方法。
- People rarely confining their sexual activity to oral sex alone（人们的性生活中很少单独进行口交）
- where people have had other sorts of sex including unprotected anal or vaginal penetration it is assumed that the higher risk activity will have given them HIV 人们有其他性行为，比如无保护的肛交和性jiao时，被认为更有可能传染HIV.
- exact details of the sexual activity have been missed out - ie whether or not ejaculation into the mouth etc 。性生活中细节被忽略了，比如是否口腔内射，等。
- Studies where one partner is known to be HIV positive and the other HIV negative are likely to be slightly skewed because the HIV positive person is likely to be on anti-retroviral medications and consequently probably less infectious anyway.研究中，一方是阳性，一方是阴性，口交通常不是2方都进行，有的阳性可能吃了抗逆转药物，使传染性降低。
The overall conclusion was that:-总观点
- Chances of acquiring HIV through oral sex with an HIV infected partner are very low. The majority of the studies reporting zero to miniscule risk.通过口交传染hiv的风险非常低。绝大部分实验认为口交的风险最小为0.
- Very large, very expensive, well controlled studies would be needed to define the question exactly. 需要更多的大量的，精确的，投入财力多的口交实验进行。
The results of a study due to appear shortly in AIDS seem to show that HIV negative gay males in sero-discordant ( a relationship where one of the partners is HIV positive and the other HIV negative) relationships have saliva which has an HIV neutralising capacity. Consequently one of the conclusions drawn is that repeated exposure to low levels of HIV may produce a level of resistance to HIV in this population.研究的结果认为一方阳性，一方阴性的同性伴侣的唾液有抑制hiv病毒的能力。
