Although men often have sex when intoxicated, basic questions remain about how alcohol affects erection. It may depend on whether blood alcohol level is ascending or descending and whether the situation calls for maximizing or suppressing erection.
To evaluate whether descending intoxication affects erection when men are instructed to maximize or suppress arousal.
Seventy-eight heterosexual men were randomized to intoxication (descending from .08% vs. no alcohol) and arousal instruction (maximize vs. suppress) conditions. Response to erotica was examined using penile plethysmography.
Compared to similarly instructed sober men, intoxicated men instructed to maximize exhibited less erection yet reported greater effort to maximize. Interestingly, intoxicated men instructed to suppress exhibited more erection than those instructed to maximize. In general, however, observed effects were modest.
Findings suggest there is no simple answer regarding how alcohol affects sexual arousal. Descending intoxication, depending on context, appears to affect erection capacity and control.
尽管男性常常在醉酒时进行性行为,但关于酒精如何影响勃起仍存在一些基本问题。这可能取决于血液酒精含量是在上升还是下降,以及当时的情况是需要增强还是抑制勃起。
评估当男性被要求增强或抑制性唤起时,酒精含量下降是否会影响勃起。
78名异性恋男性被随机分配到醉酒状态(血液酒精含量从0.08%下降 vs. 未饮酒)和性唤起指导(增强 vs. 抑制)条件下。使用阴茎体积描记法检查对色情作品的反应。
与接受同样指导的清醒男性相比,被要求增强性唤起的醉酒男性勃起程度更低,但报告称在增强性唤起方面付出了更大努力。有趣的是,被要求抑制性唤起的醉酒男性比被要求增强性唤起的男性勃起程度更高。然而,总体而言,观察到的影响较小。
研究结果表明,关于酒精如何影响性唤起没有简单的答案。酒精含量下降根据具体情况似乎会影响勃起能力和控制能力。
