艾滋病毒“治疗即预防”（TasP）在减少血清不一致夫妇的艾滋病毒传播方面非常有效。很少有同性恋和双性恋男子对TasP的态度，特别是关于男子的意愿，对TasP的信念采取行动的检查。我们在2012年底对澳大利亚男性进行了一项在线横断面调查，以调查有关艾滋病毒预防新发展的知识和信念。在839名男性（平均年龄39.5岁）中，男性倾向于不同意TasP足够有效以证明减少安全套使用是合理的，尽管艾滋病毒阳性男性的态度更有利。只有少数男性知道TasP的任何证据;四分之一的人错误地认为TasP有效性的证据已经存在于同性恋人群中。五分之一（20.5%）的男性报告说，当艾滋病毒阳性的性伴侣正在接受艾滋病毒治疗时，他们愿意与相反地位的性伴侣进行无避孕套肛交。与这种意愿独立相关的因素是：HIV阳性血清状态，报告任何serodiscordant或seronconcordant无避孕套肛交与一个固定的男性伴侣在过去的六个月，报告任何无避孕套肛交与一个偶然的男性伴侣在过去的六个月，并有更大的信念在TasP的有效性。这表明，最愿意依靠TasP来预防传播的男性已经在从事高风险的活动。生物医学艾滋病毒预防代表着一个迅速变化的环境，新的研究以及社区和政策反应正在迅速出现。对于血清不一致性伴侣的男性来说，要成功地应用TasP来降低传播风险，需要更多的支持和教育，以便在特定的关系和性环境中更好地利用TasP。
HIV 'treatment as prevention' (TasP) is highly effective in reducing HIV transmission in serodiscordant couples. There has been little examination of gay and bisexual men's attitudes towards TasP, particularly regarding men's willingness to act on beliefs about TasP. We conducted an online cross-sectional survey of Australian men in late 2012 to investigate knowledge and beliefs about new developments in HIV prevention. Amongst 839 men (mean age 39.5 years), men tended to disagree that TasP was sufficiently effective to justify reduced condom use, although HIV-positive men had more favourable attitudes. Only a minority of men were aware of any evidence for TasP; and one-quarter incorrectly believed that evidence for the effectiveness of TasP already existed for the homosexual population. One-fifth (20.5%) of men reported that they would be willing to have condomless anal intercourse with an opposite-status sexual partner when the HIV-positive partner was taking HIV treatments. Factors independently associated with such willingness were: HIV-positive serostatus, reporting any serodiscordant or serononconcordant condomless anal intercourse with a regular male partner in the previous six months, reporting any condomless anal intercourse with a casual male partner in the previous six months, and having greater beliefs in the effectiveness of TasP. This indicated that the men most willing to rely on TasP to prevent transmission were already engaging in higher risk practices. Biomedical HIV prevention represents a rapidly changing environment with new research as well as community and policy responses emerging at a fast pace. For men with serodiscordant sexual partners to successfully apply TasP to reducing transmission risk, more support and education is needed to enable better utilisation of TasP in specific relational and sexual contexts.
