为了研究人类男性交配和养育努力之间权衡的激素相关性，我们检查了58名波士顿地区男性的唾液睾酮（T）水平，这些男性未婚（n = 29），已婚无子女（n = 14）或已婚有子女（n = 15）。此外，我们要求参与者完成一份调查问卷，调查他们的人口统计学，婚姻和养育背景。我们检验了以下假设：（1）已婚男性的T水平低于未婚男性;（2）有孩子的已婚男性的T水平低于未婚男性和无孩子的已婚男性。我们还检验了一系列假设，这些假设将父母教养和配偶关系的变化与T。我们发现，已婚男性有和没有孩子有显着较低的晚上T比未婚男性。在早晨样本中，各组之间的T无显著差异。在没有孩子的已婚男性中，“配偶投资”指标的得分较高，以及在最后一天下班时与妻子共度的时间较多，都与T水平较低有关。我们认为，较低的T水平，在白天的父亲可能会促进父亲照顾人类的可能性，降低父亲将从事竞争和/或交配行为。(C)2002年爱思唯尔科技有限公司All rights reserved.
In order to study the hormonal correlates of the tradeoff between mating and parenting effort in human males, we examined the salivary testosterone (T) levels of 58 Boston-area men who were either unmarried (n = 29), married without children (n = 14), or married with children (n = 15). Additionally, we asked participants to complete a questionnaire that surveyed their demographic, marital, and parenting backgrounds. We tested the hypotheses that (1) T levels will be lower in married than in unmarried men and (2) married men with children will have lower T levels than unmarried men and married men without children. We also tested a series of hypotheses relating variation in parenting and spousal relationships to T. We found that married men with and without children had significantly lower evening T than unmarried men. No significant differences in T were found among the groups in morning samples. Among married men without children, higher scores on a "spousal investment" measure and more hours spent with a man's wife on his last day off work were both associated with lower T levels. We suggest that lower T levels during the day among fathers may facilitate paternal care in humans by decreasing the likelihood that a father will engage in competitive and/or mating behavior.
