Hercules the liger is not sterile. In fact no liger in the world is sterile. Dr. Bhagavan Antle states this so! He also believes that female ligers reproduce much better than male ligers. No male liger in the world have reproduced yet though. If the male ligers will fail to reproduce, they will definitely be sterile. br br www.ligerworld.com br www.liger-hercules.
