Men With Big Testicles Less Likely To Be Caring Fathers, Study Shows.
Men with bigger testes had a more hands-off parenting style, and the reward centers of their brains activated less when the men viewed their children's pictures. These fathers also tended to have higher testosterone levels.
The findings are fascinating and provocative, said Sarah Hrdy, an anthropologist at Citrona Farms who was not involved in the study.
"For me, the take-home message is, there is this tremendous potential for nurture in human males, albeit a potential that in different cultural and social situations is not always being tapped," Hrdy told LiveScience.
But the study also raises a number of questions, added Hrdy, who is professor emerita at the University of California, Davis; associate in the Peabody Museum of Archaeology and Ethnology at Harvard; and A.D. White professor-at-large at Cornell University.
For instance, no one knows how testicular volume changes over time (although testes do tend to shrink with age)
Next time there's a parents evening, I'll show the headmistress my clockweights just to show her how much I care.
