Fatherhood Diminishes Testosterone

According to a study reported in the New York Times and delicately recapped in The Art of Manliness, dads suffer from diminished testosterone.

after a man has a kid, his testosterone levels drop, and the more involved he gets in child-rearing, the lower his T levels fall… This reduction in testosterone is thought to help men commit to their families and stick around to rear their progeny. (Fatherhood Leads to a Drop in Testosterone)

In a big-picture kind of way, I get it. By the time junior arrives on the scene testosterone has already put in a hard day at the office. It is largely responsible for making a man big, strong and virile which may (or may not) be why a woman is drawn to him. Testosterone is also tied to aggressive behavior, ostensibly valuable for courtship and defending the female from other aggressive suitors. And then there’s that testes part, also important if junior is going to get started. And then suddenly, testosterone is less relevant. In fact, it might even get in the way. Time to cut the T levels so daddy can focus on hearth, home and juniors. No more chest thumping or wayward adventures. No need for testes. Time to change diapers and make airplane noises while trying to plug rubber-edged spoonfulls of mush into junior’s mouth. And then clean it up from his chin. And the floor.

the more he gets involved in caring for his children — changing diapers, jiggling the boy or girl on his knee, reading “Goodnight Moon” for the umpteenth time — the lower his testosterone drops. (In Study, Fatherhood Leads to Drop in Testosterone)

Perhaps the perfect papa is virtually testosterone-free? This study might generate interesting hypotheses about men’s mid-life crises. Kids are packed off to college and Viagra is floating around. Maybe long hibernating T levels start to awaken…

But, fathers, take note. Subgrade testosterone levels don’t make you a wimp. Really.

“Unfortunately,” Dr. Ellison added, “I think American males have been brainwashed” to believe lower testosterone means that “maybe you’re a wimp, that it’s because you’re not really a man. “My hope would be that this kind of research… would make them realize that we’re meant to be active fathers and participate in the care of our offspring. (In Study, Fatherhood Leads to Drop in Testosterone)

Active fathers, yes. Wimps, no. Sensitive, caring, nurturing dads who are less likely to be distracted by that sexy new associate who joined the firm. Which isn’t to say that your mojo’s totally shot, just diminished. A bit…

The lowering of their testosterone did not prevent the men in the study from having more children. “You don’t need a lot of testosterone to have libido,” Dr. Kuzawa said.

“If guys are worried about basically, ‘Am I going to remain a guy?’” Dr. Worthman said, “we’re not talking about changes that are going to take testosterone outside the range of having hairy chests, deep voices and big muscles and sperm counts. These are more subtle effects. (In Study, Fatherhood Leads to Drop in Testosterone)

So you can keep your bark, but you might lose your bite. Or something. Go, dads!
