许多青年男子报告了与避孕套相关的勃起问题(CAEP)，并与不一致和/或不完全使用避孕套有关。CAEP的潜在机制尚不清楚，也缺乏研究报告CAEP的男性在性反应方面与其他男性不同的可能性。这项研究使用心理生理学方法来检查报告CAEP的男性是否有更高的性唤醒门槛，对触觉刺激的需求更强烈，和/或更容易因为中性干扰或与表现相关的要求而失败性唤起。共有142名年轻的异性恋男性(53%报告CAEP)被提供了四个3分钟的色情电影片段。三个电影片段与以下操作之一相结合：1)分散注意力，2)表演需求，或3)振动触觉刺激。其中一个色情电影片段没有得到进一步的说明或操作。在性爱电影刺激(条件)的第一分钟、第二分钟和第三分钟(时间)内的平均阴茎周长变化进入混合模型方差分析，其中条件和时间为受试者内因素，组(CAEP/NO-CAEP)为受试者间因素。条件和时间的主效应显著，组×时间的交互作用显著。没有发现与条件有关的显著交互作用。无论拍摄条件如何，报告CAEP的男性在第一分钟内的勃起反应都比没有CAEP的男性小(F(1,141)=8.64，p<；0.005)。研究结果表明，患有和不患有CAEP的男性在性唤起的难易程度上有所不同。报告CAEP的男性需要更多的时间和/或更强烈的刺激才能唤醒。据我们所知，这项研究是第一次使用心理生理学方法来评估报告CAEP的男性的性反应。
Condom-associated erection problems (CAEP) are reported by a substantial number of young men and are associated with inconsistent and/or incomplete condom use. The underlying mechanisms of CAEP are not well understood and research examining the possibility that men who report CAEP differ from other men in their sexual responsivity is lacking. This study used psychophysiological methods to examine whether men who report CAEP have a higher threshold for sexual arousal, a stronger need for tactile stimulation, and/or more easily lose their sexual arousal due to neutral distractors or performance-related demands. A total of 142 young, heterosexual men (53% reporting CAEP) were presented with four 3-minute erotic film clips. Three film clips were combined with one of the following manipulations: 1) distraction, 2) performance demand, or 3) vibrotactile stimulation. One erotic film clip was presented with no further instructions or manipulations. Average penile circumference changes during the first, second, and third minute (Time) of the erotic film stimuli (Condition) were submitted to a mixed-model ANOVA with Condition and Time as within-subjects factors and Group (CAEP/No-CAEP) as between-subjects factor. Significant main effects of Condition and Time and a significant interaction of Group×Time were found. No significant interactions involving Condition were found. Men who reported CAEP had smaller erectile responses during the first minute, regardless of film condition, than men who reported no CAEP (F(1,141)=8.64, p<.005). The findings suggest that men with and without CAEP differ in the ease with which they become sexually aroused. Men reporting CAEP needed more time and/or more intense stimulation to become aroused. To our knowledge, this study is the first to use psychophysiological methods to assess sexual responsivity in men who report CAEP.
