The other problem was that the male turtle's penis had been damaged in a fight with another male turtle years earlier, so he could not have sex very well. Starting in 2015, the zookeepers collected the male turtle's male reproductive liquid and placed it inside the female using medical tools. Again, the female turtle laid eggs, but none hatched. The scientists used a different medical technique every year, trying to find one that worked. In 2019, the female turtle died because she did not wake up from the medicine the zookeepers gave her to make her sleep during the medical process. The zookeepers cut out and froze tissue from her female reproductive organs.
