Jinzhu, the 11 year old male panda of the Wolong Nature Reserve in China’s Southwest Sichuan province, gave birth to twin cubs in August of 2007. The two cubs, probably female, have done just fine since their surprise arrival.
Li Desheng, an expert on pandas, claimed that the apparent mistake in properly sexing Jinzhu was because pandas have almost no cock. “The penis of an adult panda is only about three centimeters long,” he said. There may have been other clues, however.
In 2000 Jinzhu was paired off with a female panda to mate. When neither of them want to screw, the vets decided on artificial insemination. Trying to “milk” sperm from Jinzhu led to the discovery that the bear had no cock at all, which, rather than bringing the veterinarians to the conclusion that a bear with no cock might be a girl bear, instead caused them to announce that Jinzhu was a hermaphrodite with underdeveloped sex organs. (Obviously the more likely scenario.) Curiously, genetic testing showed that Jinzhu had perfectly normal female panda chromosomes.
Thus it was a complete surprise to everyone when the bear had babies. God works in mysterious ways.
