The current study extends previous research on testosterone (T) and mating effort by examining whether relationship commitment and satisfaction explain variance in T beyond relationship status alone.
Salivary testosterone and self-reported assessments of relationship commitment and satisfaction were assessed among 90 heterosexual men and women (age M = 23.57) in a cross-sectional community sample.
Relationship commitment was significantly related to T among men (P < 0.01), with increasing levels of commitment predicting lower T, even among paired men (P < 0.05). In contrast, relationship commitment was not related to women's T (P > 0.05). Controlling for relationship commitment, satisfaction did not predict T levels in men or women (P's > 0.18).
The association of increasing relationship commitment with reduced T levels in men confirms and extends prior research linking T with mating effort. Together with previous research, this study suggests that T does not vary with relationship commitment or quality in monogamous, heterosexual women.
本研究通过考察关系承诺和满意度是否能在关系状态之外解释睾酮（T）的变化，从而扩展了先前关于 T 与交配努力的研究。
在一个横断面社区样本中，对 90 名异性恋男性和女性（年龄 M=23.57）进行了唾液睾酮和关系承诺与满意度的自我报告评估。
关系承诺与男性的 T 显著相关（P<0.01），随着承诺水平的增加，T 水平降低，即使在配对男性中也是如此（P<0.05）。相比之下，关系承诺与女性的 T 无关（P>0.05）。控制关系承诺后，满意度在男性和女性中均不能预测 T 水平（P 值均>0.18）。
关系承诺的增加与男性 T 水平的降低相关，这证实并扩展了先前将 T 与交配努力联系起来的研究。与先前的研究一起，本研究表明，在一夫一妻制的异性恋女性中，T 并不随关系承诺或关系质量而变化。
