北美之前的研究支持这样的观点，即男性参与承诺的浪漫关系与较低的睾酮(T)水平有关。在这里，我们测试了一种预测，即参与承诺的浪漫关系(配对)的本科生男性比没有参与这种关系的男性(非配对)的T水平更低。此外，我们还测试了这些差异是否在当天晚些时候收集的样本中比早些时候收集的样本更明显。在这项研究中，107名本科生男性填写了一份问卷，并在一天中的不同时间收集了一份唾液样本(从中测量了受试者的T水平)。与之前的研究一样，陷入承诺的浪漫关系中的男性唾液T水平较低，尽管只在一天中的晚些时候。此外，对未配对受试者的额外分析表明，没有恋爱经验的男性的T水平低于有经验的男性。最后，虽然结对的男性的T水平低于未配对的男性，但那些处于当前关系最早阶段(不到6个月)的男性的T水平高于未配对的男性以及处于长期关系中的男性。这些结果表明，雄性睾丸激素水平的变化可能反映了交配努力的不同行为分配。
Previous research in North America has supported the view that male involvement in committed, romantic relationships is associated with lower testosterone (T) levels. Here, we test the prediction that undergraduate men involved in committed, romantic relationships (paired) will have lower T levels than men not involved in such relationships (unpaired). Further, we also test whether these differences are more apparent in samples collected later, rather than earlier, in the day. For this study, 107 undergraduate men filled out a questionnaire and collected one saliva sample (from which a subject's T level was measured) at various times across the day. As in previous studies, men involved in committed, romantic relationships had lower salivary T levels, though only during later times of the day. Furthermore, additional analysis of the variation among unpaired subjects indicated that men without prior relationship experience had lower T levels than experienced men. Finally, while paired men as a group had lower T levels than unpaired men, those men at the earliest stage (less than six months) of a current relationship had higher T levels than unpaired men as well as men in longer-term relationships. These results suggest that variation in male testosterone levels may reflect differential behavioral allocation to mating effort.
