Transmission of HIV through via receiving oral intercourse is possible, but not probable. The most likely scenario for this to occur would involve an open "sore" on the penis of the insertive partner and high viral load within the oral cavity of the person engaged in receptive oral intercourse. Is this a likely scenario? No. For the receptive person to have a high viral load there would have to be either blood within the mouth, or multiple oral ulcerations. The latest research in regards to oral transmission of HIV is summarized below.HIV通过被动口交进行传播是有可能性的，但是不太可能。经过被动口交传播hiv的最可能发生的情形是：在插入方阴茎上有一个开放性的创口，同时在口腔方的口腔之内有高的病毒载量。这个情形常见吗？不。对于接受方而言，个体的口腔内必须有血液或者有多处口腔溃疡才能达到较高的病毒载量。有关艾滋病的最近研究如下：

A study conducted by researchers the Centers for Disease Control and Prevention and the University of California at San Francisco shows that oral sex is a frequent method of spreading HIV. Oral sex was the likely cause of 8 percent of recent HIV infections in a group of 102 gay and bisexual men in San Francisco. The only risk behavior found in eight of the men was oral sex, which they thought had little or no risk. The scientists concluded that the men must have contracted HIV through giving oral sex, not receiving it, without using a condom.
在加州大学的一项研究中发现，在102名同性恋或双性恋中有8人很可能是通过口交被感染hiv的。但是，这些被感染者全都是主动者，无一是被动者，无套。

但有可能感染其他性病，例如淋病，很不好受。
