Atten-TION: Male Soldiers Are Growing Breasts

Like armies everywhere, the German military is filled with macho, chest-thumping rituals. But one battalion has found there's a downside to all that chest-thumping: The male soldiers are growing breasts ? and only on their left sides.

The Wachbataillon unit performs precision military drills at official ceremonial functions, the German Herald reports. Many of their drills involve smacking their rifles against the left side of the soldiers' chests. And all that pounding on the same spot has stimulated the production of hormones that cause man boobs to grow.

"There is a very significant link between the activity in the ? battalion and the development of the breast on the left side," Dr. Bjorn Krapohl, director of plastic surgery at the military's main hospital in Berlin, told the Herald. "They need to change the way they drill."

The growth of male breasts isn't altogether uncommon: The condition is known as gynecomastia, and it's caused by an imbalance in testosterone and estrogen levels. There have been cases where chest injury has caused gynecomastia, though it's rare. Plastic surgeons report that teenage boys ? who are particularly prone to the condition ? often have breast tissue removed when gynecomastia becomes a big psychosocial problem.

In a study of the German soldiers, published in January 2012, Krapohl and colleagues found significant differences between the guards with gynecomastia and a control group of healthy males without signs of gynecomastia. Those in the Guard Battalion in Berlin had lower testosterone levels and higher body mass indexes (BMI), or a measure of body fatness. [The 9 Most Bizarre Medical Conditions]

While the researchers hypothesize the mechanical stress from daily drills may be the underlying cause, they are not sure exactly how the "chest thumping" causes the breast growth. "There are no experimental studies identifying possible mechanisms at the cellular level that might induce gynecomastia mechanically," they write in the journal article, adding that these findings may provide new impetus for such studies. The research is detailed in the journal GMS Interdisciplinary Plastic and Reconstructive Surgery DGPW.

Other research has shown that while gynecomastia tends to be symmetric, it can also be asymmetric; the lopsided type tends to be more common on the left side, according to a review in the Cleveland Clinic Journal of Medicine.

Over 70 percent of the German battalion's soldiers have been diagnosed with significant gynecomastia. Military officials have promised to keep an eye on the men's breasts.

"The affected soldiers are being medically supervised and treated individually," an army spokesman told the Herald.
