These German soldiers aren't boobs, so why are they growing them?
A new military report published in the German Medical Science journal and obtained by the German Herald finds that dozens of soldiers in the Wachbataillon unit have developed the condition because the drills they perform stimulate male mammary glands.
The director of plastic surgery at the military hospital in Berlin, Professor Bjorn Krapohl, said it's likely the repeated slapping of the soldiers' rifles on the left side of their chests during drills stimulates the glands to produce hormones, which creates the one-sided-boob effect.
