Medical, social, and sexual histories were taken from 198 men attending a department for sexually transmitted diseases. Their blood was tested for hepatitis B surface antigen and its antibody, and also for syphilis and liver function. Infection with hepatitis B virus was found to be common among practising homosexuals and to occur much more frequently in them than in heterosexuals. Hepatitis B appeared to be transmitted sexually rather than by other means, but it was not possible in this study to link its transmission with any particular homosexual practice. However, risk of infection increased considerably with the number of sexual partners and nearly half of those with more than 40 sexual partners had been infected.
对198名前往性传播疾病科就诊的男性进行了医学、社会和性病史采集。检测了他们血液中的乙型肝炎表面抗原及其抗体，还检测了梅毒和肝功能。发现乙型肝炎病毒感染在男同性恋者中很常见，且在他们当中的发生率远高于异性恋者。乙型肝炎似乎是通过性传播而非其他途径传播，但在这项研究中无法将其传播与任何特定的同性恋行为联系起来。然而，感染风险随着性伴侣数量的增加而大幅上升，有超过40个性伴侣的人中近一半已被感染。
