Let me put on my armchair psychologist hat and say: I think it's due to the fact that in our society, men aren't socialized to think about feelings, and in fact, men are socialized to not have them. So it's not a surprise that these professions that require some form of feeling caring for one another lack men. For example teaching (sympathizing and empathizing with students and caring about their future), nursing (caring about patients well being and health), and PR (caring about the success of your customers) all require feeling.
