It's not that they refuse, they literally don't know how to do it. Once, a panda was discovered trying to have sex using another panda's paw, because they really don't know the mechanics of it, as if they didn't have the instinct to do it. That's why they often show them panda porn, which is literally videos of pandas having sex, to arouse them and teach them.Ah a fine area of research. As an aside why the fuck do pandas refuse to fuck in captivity?
