Possibly it is, if you had been trying to pass something for 24 hours, if you were passing something weighing 7lbs, and having a 4 inch incision to avoid tearing done with little or no anaesthetic and then after being exhausted being told to deliver a 6 inch piece of your insides (The placenta) that have to come away or you will die. Most men could cope with that i am sure lol
One aspect of child birth men could never cope with is the due date arriving and the baby staying put. Imagine if they had to wait an extra week or so for the birth? They'd go into meltdown.
