Yes, your testicles have taste buds.
As absurd as it sounds, It's true. According to an in depth article posted in the Proceedings of The National Academy of Sciences your testicles have the ability to taste and sense Sweet and Savory flavors. The ability to sense these flavors is directly related to Male fertility and sterility. Scientists hope that continued study of this ability in the testicles will lead to new solutions to fertility issues in men. So be sure to keep those taste buds fresh and clean.
