Male Iatrophobia

What is it with men who are sick not wanting to go to the doctor?
They cough, hack, moan, sniff, snort, moan some more...but they won't get out and see a doctor who could actually give them medicine to get rid of the sickness before they spread it to everyone they know.
Men are such babies when they are sick too. I know it sucks to be sick, but they act like if they aren't feeling 100% all of the time that it's the end of the world. They can't do anything but lay around. They become what some Navy folks would call a NUB (non-useful body). They don't shower or do much of anything that requires them to be vertical until whatever it is that has them at death's door goes away.
I think this might go along with the thing where guys won't ask for help also. Take any man to a store where they don't know where stuff is and they will wander around aimlessly until they either find what they are looking for or give up (and guess which usually comes first...).
Is this a societal thing? Are men under some kind of pressure to become germ-free, no-help-needed, super humans?
