The pregnancy was easy, the delivery a breeze. This was the couple’s first baby, and they were thrilled. But within two months, the bliss of new parenthood was shattered by postpartum depression.

A sad, familiar story. But this one had a twist: The patient who came to me for treatment was not the mother but her husband. ...

Up to 80 percent of women experience minor sadness — the so-called baby blues — after giving birth, and about 10 percent plummet into severe postpartum depression. But it turns out that men can also have postpartum depression, and its effects can be every bit as disruptive — not just on the father but on mother and child.

We don’t know the exact prevalence of male postpartum depression; studies have used different methods and diagnostic criteria. Dr. Paul G. Ramchandani, a psychiatrist at the University of Oxford in England who did a study based on 26,000 parents, reported in The Lancet in 2005 that 4 percent of fathers had clinically significant depressive symptoms within eight weeks of the birth of their children. But one thing is clear: It isn’t something most people, including physicians, have ever heard of.

Conventional wisdom holds that two parents are better than one. Scientists are now finding that growing up without a father actually changes the way your brain develops.

German biologist Anna Katharina Braun and others are conducting research on animals that are typically raised by two parents, in the hopes of better understanding the impact on humans of being raised by a single parent. Dr. Braun's work focuses on degus, small rodents related to guinea pigs and chinchillas, because mother and father degus naturally raise their babies together.

When deprived of their father, the degu pups exhibit both short- and long-term changes in nerve-cell growth in different regions of the brain. Dr. Braun, director of the Institute of Biology at Otto von Guericke University in Magdeburg, and her colleagues are also looking at how these physical changes affect offspring behavior.

Their preliminary analysis indicates that fatherless degu pups exhibit more aggressive and impulsive behavior than pups raised by two parents.
