Scientists discover bacteria in testicles
Men's testicles have their own bacteria and they are different depending on fertility, scientists have discovered for the first time.
Testes were thought for a long time to have been sterile environments, but researchers in Italy have found otherwise.
Experts say there are microorganisms living naturally in the testes, and the diversity of this environment within the body could give clues about a man's fertility.
Men with more types of bacteria in their testes could be expected to be more fertile, while a smaller range of organisms could mean a man has a lower sperm count. If the testes have only one type of bacteria, it means the quantity of sperm is so few that they cannot even be extracted by surgery.
