Low testosterone dads. I’m Bob Hirshon and this is Science Update.
New fathers undergo hormonal changes, including a drop in levels of testosterone, according to Notre Dame anthropologist Lee Gettler, speaking at the annual meeting of the American Association for the Advancement of Science.
And we’re also able to look at their day-to-day involvement with their children. And so we found that men who perform the most day to day childcare in a sort of hands on, physically caring way tend to have lower testosterone than fathers who report no involvement in those kind of activities.
Gettler says that low testosterone doesn’t mean “less masculine.”
If you ask many fathers whether taking care of their kids and helping to provide for their family’s an important component of what makes them a man, or a good man, I think many would say “yes.”
He and his team are now looking at babies, mothers and fathers together as a system, and factors affecting the child’s emotional development. I’m Bob Hirshon, for AAAS, the science society.
