Apparently direct contact with a polar bear is bad for the prostate (as well as the heart, lungs, kidneys, and just about anything but the brain which is usually terminal at this point:

"The popularity of the zoo's polar bears soared in July 1994 after an Australian tourist climbed over the moat and the first fence to photograph them. Binky grabbed the woman through the bars of the inner fence, pulled off her tennis shoe, chewed on and broke her leg, and let her go. The next day a news photographer visited the polar bear pen and caught the picture that became the icon that Anchorage embraced. It was flashed around the world over the AP wire.

The reaction in Anchorage was instantaneous. Binky became a hero. T-shirts, post cards, coffee mugs, bumper stickers, even jewelry sprang up boasting the image of Binky with the tennis shoe. The victim was good-- natured about the episode. Interviewed from her hospital bed, she agreed that it was the "stupidest thing" she had ever done. Letters to the editor expressed approval of her penitent attitude. She had learned one of the most important lessons of the North, that wild animals are not pets.

Then, in September 1994 two local teenagers on a drunken spree broke into the zoo at night. As one of the young men crept into Binky's pen, apparently for a swim in the pool, Binky lunged at him and chewed his leg.7 By now Binky had become a folk hero, so public opinion was on the side of the polar bear from the beginning. The point made in press coverage and letters to the editor was, again, that polar bears are wild animals, not pets. Like the Australian, this victim, a non-citizen (i.e., a minor) who had been incapacitated by alcohol, was something of an outsider."
