Testosterone (T) is lower among fathers and men in committed relationships, suggesting that
the hormone mediates the trade-off between mating and parenting effort. The function of T in …

In species with a high level of paternal care, including humans, testosterone (T) is believed
to help mediate the trade-off between parenting and mating effort. This hypothesis is …

Testosterone (T) is thought to help facilitate trade-offs between mating and parenting in
humans. Across diverse cultural settings married men and fathers have lower T than other …

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 …

Testosterone has been hypothesized to modulate the trade-off between mating and
parenting effort in males. Indeed, evidence from humans and other pair-bonded species …

Research points to an association between testosterone (T) and partnering in some women
and men, and this association has been interpreted as an effect of either relationship status …

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. This model may apply …

Recent evidence suggests that, in humans, variations in testosterone (T) levels between
men reflect their differential allocation in mating versus parenting efforts. However, most …

One of the fundamental life history challenges facing human males is the allocation of
reproductive effort to its primary components: mating and parenting effort (Trivers, 1972; …

A growing body of evidence, almost entirely from North America, has found that male
testosterone levels are positively associated with mating effort (male–male competition and …
