Why is it that when working women are featured, the fact that they are a wife and mother of X number of children is almost always mentioned, but not the men?

Watching Untold Stories of the ER. There was a female ER doctor, and the point that she is also a wife and the mother of 3 small children was made.

I never hear commentators say, “This ER doctor is a husband and the father of 3 small children.”
