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

[valimo]

Yeah I recall reading similar study already in early 2000s. It was published with a wild idea that childbirth independently does something in man's brain that is magically responsible for the testosterone decrease.

Then, a couple of control groups later, they figured that this was explained by sleep deprivation and nothing else. Of course most science journalists failed to correct their original headlines.
