They eat. They sleep. They hardly move. And they’ve got almost no libido.

We’re talking about pandas.

Zhang Zhihe, director of Chengdu Research Base of Giant Panda Breeding in Chengdu, China, says that if the male pandas don’t like the females’ personality, they won’t mate. Not a problem for humans, but a big problem for securing the future of the panda species.

Panda population is shrinking with only 1,600 in the wild and 294 in captivity worldwide.

Panda behavior tends toward isolation and they are traditionally poor breeders. Captivity exacerbates the problem. To get young male pandas curious about sex, scientists have tried a combination of porn, sexercises, and the occasional ménage à trios. They have proved successful.

Because of the new breeding tactics, Zhihe says that more than 60 percent of his pandas are now capable of having sex on their own. With 300 sexually active pandas, scientists will have the genetic diversity needed to ensure the survival of the species for another century. Scientists could eventually consider returning them to the wild.
