Breeding captive giant pandas has always been a difficult challenge!
First of all, female giant pandas have their estrus climax and are receptive to mating for just two or three days, which is too short a time.
In the wild, giant pandas engage in martial contests as a prelude to mating. They traverse mountains and valleys in search of food and are robust in body. When they fight, they show no signs of weakness; Several male pandas rush over upon detecting a female's scent, and after a clash, the victorious male remains, filled with a heroic air that certainly pleases the female panda.
The female actively reciprocates, and the male, strong and vigorous, finds mating on the ground a piece of cake, not to mention the more elaborate couplings in trees.
Giant pandas have evolved this mechanism, probably as a means of conserving effort!
With a nature both lazy and homebody-like, they won't move an inch if there's food at hand, avoiding social interactions with other pandas.
