Nature preserves are showing porn to pandas to increase their sex drives.

Male pandas have notoriously low sex drives, and pandas are extremely picky when choosing mates. This makes it very difficult when trying to encourage pandas to reproduce in captivity. This is really bad for the survival of their species, especially since there are only 1600 pandas in the wild, and an additional 294 in captivity. So how can we save the pandas? Panda Porn!

Researches in China have begun showing videos of pandas having sex to male pandas in their cages to encourage them to have sex. So far, it's working! 60% of male pandas in captivity are able to have sex now, up from a low of 25%.

The scientists are also experimenting with a couple other fertility practices. They are incorporating a workout routine for male pandas designed to increase their hind leg strength and stamina. They're also encouraging young pandas to engage in threesomes with older panda couples to get the young male pandas interested in sex at an early age.
