These findings suggest that high testosterone women are more likely to be influenced by the quality of other family relationships than low testosterone women, and that testosterone may be more detrimental to mother-child relationship quality when there is a lack of warmth in other family dyads. However, the finding that testosterone is linked to parent-child relationship quality, whether transient or stable, does support our hypotheses and helps to enlarge our understanding of the role of testosterone in developing strong family relationships. (2) Marital satisfaction moderates the relationship between parental testosterone and the quality of parent child relationships. Similar to the findings presented in the fathers’ models, there were no significant direct effects of mothers’ testosterone on mother-child closeness (Model 1). These symptoms can affect a man’s mood and energy levels, making it challenging to engage actively in parenting activities. Both low and high testosterone levels can impact a man’s ability to be an involved and nurturing parent. This hormone helps foster feelings of protectiveness, empathy, and affection, which are essential for healthy parent-child relationships. Testosterone also plays a crucial role in establishing and maintaining emotional bonds between fathers and their children. However, it’s important to note that the relationship between testosterone and parenting is complex. Research suggests that testosterone levels also play a role in nurturing and caregiving behaviors in men. Adjustment of T production has been proposed as a physiological mechanism underlying this tradeoff, with males who focus on mating effort predicted to maintain elevated T, whereas males who cooperate with a female partner and invest in parental care should reduce T production (6, 8). In species in which males care for young, testosterone (T) is often high during mating periods but then declines to allow for caregiving of resulting offspring.

Fathers that score lower on empathy tend to be more aggressive and frustrated at the child rather than concerned about soothing the child, which is paired with Testosterone elevation. This research is vital because a nurturing and supportive environment is conducive to a healthy upbringing for the child. Our findings suggest that human males have an evolved neuroendocrine architecture that is responsive to committed parenting, supporting a role of men as direct caregivers during hominin evolution (13, 14, 21). Finally, fathers who were most involved in childcare had lower T compared with fathers who did not participate in care. Among the men in our sample who were single nonfathers as young adults, those with higher waking T were more likely to have become a partnered father by the time of follow-up. 2009 AM and PM T values among fathers varying in daily physical childcare. However, to date, no human study has monitored hormonal changes longitudinally as single nonfathers transition into stable partnerships and become fathers. Although these cross-sectional correlations are generally consistent with the presumed suppressive effect of partnering and fatherhood on T production (a "state" effect), such findings could alternatively result if men with low T are more likely to become partnered or fathers (a "trait" effect) (25). In this article, we will explore the intricate relationship between testosterone and parental behaviors. The results suggested that this relationship was possible but only in fathers who experienced at least moderate testosterone increases following the Inconsolable Doll task. Fathers with more pronounced alexithymia, as well as those who experienced a larger testosterone increase after the task, tended to exhibit lower coparenting quality when their baby was three months old. When the child reached 24 months, the family attended the third study visit, during which the child completed two prosocial behavior tasks. This could help clarify why fathers of older children show this distinct biological profile. The findings revealed clear patterns linking partnering and parenting to hormonal variations. They distinguished between men living with younger children aged five and under and those living with older children aged six to seventeen. The team categorized the men based on their relationship status and their living arrangements with children.

Although testosterone status is relatively stable across time (Granger et al., 2004), additional assays of testosterone at multiple times (cf. Dariotis, Chen, & Granger, 2016) would be useful to bolster the longitudinal findings we observed given that testosterone was assayed from a single saliva collection. The link between family roles and testosterone appeared consistent across the age range of 20 to 60. The analysis showed that neither being partnered nor living with children increased a man’s likelihood of having clinically low testosterone. The researchers hypothesized that the lower testosterone seen in fathers is an adaptive biological trait rather than a pathology. Partnered men living with infants or toddlers did not show a significant additional drop in testosterone compared to partnered men without children.
