母性关怀的组织和激活被认为受到激素的高度调节，越来越多的证据表明，父性关怀的表达也与内分泌底物有关。我们研究了绒猴父亲（Callithrix geoffroyi）的父亲行为和类固醇激素之间的关系，并评估了父亲的行为关系是否被以前的后代照顾经验的男性改变。根据先前的研究结果，我们预测睾酮，雌二醇和皮质醇将降低出生后的后代，并将在最大的婴儿携带期间最低。此外，我们预测，产后的变化，携带的努力和激素水平将受到水平的后代护理经验。分娩努力和其他父亲的照顾行为在产后期间经历了时间的变化，但这些模式与同期激素浓度的变化无关。有一个有限的影响，子女的护理经验对激素浓度，但经验被发现发挥了作用，在表达父亲的照顾，有经验的父亲从事显着更多的婴儿allogrooming比没有经验的父亲。此外，没有经验的父亲增加了食物分享的频率，以应对整个产后期间的婴儿乞讨，而有经验的父亲表现出一贯的低水平。我们认为，经验因素的结合和增加的作用，异源父母在后代护理导致这些变化。然而，它似乎激素的变化可能不会影响父亲的反应，在白脸绒猴父亲和父亲的行为关系并不严重依赖于男性以前的后代护理经验。
The organization and activation of maternal care are known to be highly regulated by hormones and there is growing evidence that expression of paternal care is also related to endocrine substrates. We examined the relationship between paternal behavior and steroid hormones in marmoset fathers (Callithrix geoffroyi) and evaluated whether hormone-paternal behavior relationships were altered by previous offspring-care experience in males. Based on previous findings, we predicted that testosterone, estradiol, and cortisol would decrease following the birth of offspring and would be lowest during the period of maximal infant carrying. Furthermore, we predicted that post-partum changes in carrying effort and hormone levels would be influenced by the level of offspring-care experience. Carrying effort and other paternal care behaviors underwent temporal changes over the post-partum period, but these patterns were not related to variation in hormone concentrations over the same period. There was a limited effect of offspring-care experience on hormone concentrations, but experience was found to play a role in the expression of paternal care, with experienced fathers engaging in significantly more infant allogrooming than inexperienced fathers. Furthermore, inexperienced fathers increased the frequency of food sharing in response to infant begging across the post-partum period, while experienced fathers displayed consistently low levels. We posit that a combination of experiential factors and an increased role for alloparents in offspring-care led to these changes. However, it appears that hormonal changes may not influence paternal responsiveness in white-faced marmoset fathers and that hormone-paternal behavior relationships are not critically dependent on a male’s previous offspring-care experience.
