why is it girls experiencing dysmenorrhea? why not the boy?

Simply because dysmenorrhea is a condition marked by painful menstruation. Boys don't suffer from dysmenorrhea because they dont have menstruation. ^^ Dont fret and think that it's unfair. The male counterpart of it is circumsition.. LOLS! Their only advantage is that they only get hurt by circumsition once in their entire life unlike us girls who suffer from dysmenorrhea every month. But not all girls have dysmenorrhea, right?

i dont know maybe they dont feel like what we feel but dont you worry they also menstruation but not color red, maybe white or yellow!!!!!

wahahaha....i will thinkking of that too...why only girls should experience that!!!!well maybe because its our part...or its part of our life....

Dysmenorrhea literally means "painful menstruation". Boys do not experience menstrual cycles, they do not menstruate, only girls do. All right?
