Kids vs. Scantily Clad Women: Which Do New Dads Prefer and Why?

We’ve written previously that fatherhood is associated with decreased levels of testosterone in dads (except for when a testosterone boost might come in handy). For the most part, the general belief has been that the dads’ lower testosterone limits their impulses to mate (presumably not with their baby-momma), thus keeping them invested in their children.

Some recent research from Emory University, however, suggests another, or additional, possibility.1 Specifically, the researchers compared the testosterone and oxytocin hormone levels of a group of fathers of 1-2 year old children with hormone  levels of men without children. In addition to collecting blood samples to measure the hormones, the researchers also scanned the brains (via MRI scans) of all the men while they were looking at 3 types of pictures: 1) children’s faces (of the same sex and age as their own kids, and depicting a range of emotional expressions), 2) unknown adult faces displaying similar emotions, and 3) scantily clad women. The research team was interested in whether fathers vs. non-fathers responded neurologically (i.e., as assessed via increased brain activation) to the different types of images and, if so, what role hormones play in those neural responses.

Who's Your Daddy?

Assuming no freak hospital mix-ups, mothers can be 100% sure that a child that she bears and raises is, in fact, genetically her own. Fathers, however, can’t be quite so sure. Even if “dad” engages in vigilant mate guarding, there’s always the possibility that his partner snuck off for some horizontal mambo action with another guy. Evolutionary psychologists call this the “paternal certainty problem”— men who have been cuckolded and are unknowingly raising a child that’s not their own have failed, from an evolutionary perspective, at passing on their genes. And it turns out that a significant number of men have failed to solve this problem.

Testosterone: It's There for Dads When They Need It

I have two kids. One is 3½ and generally sleeps through the night. The other is 14 months old and either fancies himself as living on a farm or simply likes to jack with his parents by waking up most mornings between 4 and 5 a.m. He may or may not go back to sleep after a trip to the milk bar, typically depending on how late we went to sleep the evening prior (it’s uncanny). Most nights, I admittedly sleep through the first of his wake-ups, and, in fact, often have no conscious recollection of ever hearing him squawk for us from the adjacent room. But, when my wife is out of town or taking in a way-too-early spin class, I find myself jumping out of bed with the urgency of a testosterone-fueled (albeit very tired) man-protector, ready to address whatever it is that has awoken young Mowgli.
