Across vertebrates, testosterone is an important mediator of reproductive trade-offs, shaping
how energy and time are devoted to parenting versus mating/competition. Based on early …

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 …

Objective Cross‐culturally, men's T declines in response to pairbonding and fatherhood, but
less is known about what happens to T during and after life history transitions that …

Male testosterone (T) decreases in response to childbirth. Longitudinal support for this has
come from samples across cultures. In this study, we look at individual differences in this …

Most research shows that fatherhood is related to reduced testosterone (T) levels, but
relationships between the number of children and T levels are not addressed. In humans …

Males in vertebrate species with biparental care commonly face a life history trade-off
between investing in mating versus parenting effort. Among these males, testosterone 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 …

Testosterone (T) is linked to human mating and parenting. Here, we comprehensively
reviewed evidence on whether, in men and women, 1) basal T levels are related to mating …

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 …

Men have the capacity to respond to the transition to fatherhood and nurturant investments
in their partners and children with shifts in neuroendocrine function (such as decreased …
