In order to separate hormonal from social effects on adolescent male sexual behavior, serum hormone assays were performed and questionnaire data on sexual motivation and behavior were collected on a representative sample of 102 boys in grades 8, 9, and 10 of a public school system. Free testosterone was a strong predictor of sexual motivation and behavior, with no additional contribution of other hormones. Including measures of pubertal development and age (indexing the effects of social processes) indicated no additional effects. Free testosterone, therefore, appears to affect sexual motivation directly and does not work through the social interpretation of the accompanying pubertal development.
为了区分激素和社会因素对青少年男性性行为的影响，我们对公立学校系统中8、9、10年级的102名男生进行了代表性抽样，检测血清激素水平，并收集了有关性动机和性行为的问卷数据。游离睾酮是性动机和性行为的有力预测指标，其他激素并无额外作用。纳入青春期发育和年龄的测量指标（反映社会过程的影响）后，未发现其他影响。因此，游离睾酮似乎直接影响性动机，并非通过伴随青春期发育的社会解读起作用。
