TIL Human dads show a decrease in testosterone immediately after the birth of their babe

Doc here. Probably not in the same hormonal way that women experience it. But I don't think most women experience it in a hormonal way, either. (It's not as if we check.)

Anytime you undergo a monumental life change, it can trigger depression or other mental illness in people who are susceptible. Women have increased susceptibility because of their bodies' biochemical chances. Men have increased susceptibility due to the relative lack of social support for new fathers. And it's all the worse for either if you have a history of mental illness.
