Shocking New Study Shows How to Tell a Good Dad

men drop testosterone babyGood news for those of us who already know that men are as dramatically changed by bringing home a newborn as moms. Bad news for men who think their testosterone levels define them. Science says after a new baby comes home, men's testosterone levels drop. And the more men get involved with their children, the lower those man hormone levels go.

I say good news, because it's physiological proof that men also have to adapt to babies and have done so throughout time. Their bodies change, not unlike women's, when faced with caring for a newborn. Irrefutable proof that a man's job isn't over the minute he pulls up his pants. And those really great dads who continue to interact with their kids and stay involved? Well, they keep changing. 


The more involved dads, the lower testosterone levels. Of course this study shows that men who become fathers usually have higher testosterone levels to begin with, hence the ability to grab onto and mate with a lady. So they're not losing testosterone so much as gaining a family -- the ultimate win. You know, perpetuating their genes and all.

It's good, of course, to have proof that there has always been a need for men to be part of the child-rearing process, as this study shows. They aren't just sperm-spewing animals that have no interest in committing to the family they helped to create. So there goes that "I've got to spread my seed!" argument. Modern couples reap the benefits of involved parents of both sexes, but clearly this has always been the case. Sexist pigs of 20th Century America, you've been proven wrong yet again. Or as the co-author of the study put it so well, "The only way mothers could have highly needy offspring every couple of years is if they were getting help."

I've also always wondered if men who were very involved with the day-to-day upbringing of their children didn't have lower incidences of infidelity. My logic was, how could a man who was so much a part of a family unit destroy that for a fling? It does seem to correlate, as involved dads have lower testosterone levels and might not react as strongly to a flirty co-worker, especially if they're focused on what's at home.

What do you think about this study?
