A company is selling men's underwear that blocks cell phone radiation, which in turn will protect their fertility. 

Apparel company Belly Armor sells clothes and accessories to block the body from radiation. Originally geared toward pregnant woman looking to protect their unborn child, the company recently launched a line of boxer briefs to protect men's fertility. 

"If you're a guy, how are you going to know that putting your cellphone in your pocket will do things to your sperm," Katherine Niefeld, spokesperson for Betty Armor, tells New York Post. 

Men often carry their cell phones in their pockets, which allows cell phone radiation to emit near their genital areas. 

Niefeld tells NY Post the only reason men aren't looking for protection against radio waves is because they don't realize they are at risk. 

Last year, a study by Enviormental Group found that men who carried their cell phones in their pockets had less mobile sperm than those who carried their phones elsewhere, due to the phone's radiation. 

Belly Armor's men's boxer brief that claims to have 99.9 percent efficacy will go on sale tomorrow for $49.
