What Otters' Penis Shrinkage Could Mean for Humans, Cardiff University Study

Scientists are concerned about the deformed sex organs of England's otters — and what it might mean for humans. The furry mammals are found in rivers throughout Britain, but male otters aren't what they used to be. An alarming number of them now have shrunken penis bones (baculum), as well as undescended testicles (cryptorchidism) and cysts on sperm-carrying tubes, according to a new report written by Cardiff University scientists.
