By Zoila Palma: Men experience significant hormonal and neurological changes as they transition into fatherhood, with researchers finding these shifts can influence behaviour and impact a child’s wellbeing.
While much attention has traditionally focused on how women’s bodies prepare for motherhood, growing evidence shows that men also undergo biological changes—often beginning before a child is born, BBC reports.
Research highlighted by primatologist Sarah Blaffer Hrdy suggests that men possess an inherent biological capacity to be nurturing and protective caregivers.
Studies in both animals and humans indicate that fathers experience hormonal fluctuations similar to those associated with motherhood, reinforcing the idea that active parenting in men is rooted in biology rather than purely cultural shifts.
One of the most consistent findings is a drop in testosterone levels among fathers.
Research led by Lee Gettler found that men who became fathers showed significantly lower testosterone levels compared to non-fathers, with the largest decreases observed in those most involved in childcare. Additional studies also linked lower testosterone to increased responsiveness to infants and stronger postnatal engagement.
Scientists have also identified changes occurring even before birth. Research by James K Rilling found that expectant fathers already show reduced levels of testosterone and vasopressin during pregnancy, with lower levels associated with greater involvement after the child is born. At the same time, hormones such as oxytocin—commonly known as the “love hormone”—increase in fathers, particularly during early interactions with their children, reinforcing bonding and caregiving behaviour.
Further hormonal changes include rises in prolactin, a hormone typically linked to maternal care. Studies led by Darby Saxbe found that higher prolactin levels in expectant fathers were associated with stronger emotional bonds to their unborn children and predicted greater involvement after birth. These findings suggest that men undergo a coordinated hormonal shift that supports parenting roles.
Beyond hormones, fatherhood also appears to reshape the brain.
Brain imaging studies show structural and functional changes in new fathers, particularly among those who form strong bonds with their children or take on more caregiving responsibilities.
