Specialists attempting to save the species from extinction saw the fertilised cell degenerate within days after thawed-out sperm – harvested from Tam, the last male rhino – was injected into it.It is learnt that the egg cell had failed to divide after fertilisation, and no embryo was formed.
The treatment was led by Professor Arief Boediono, a world-class IVF practitioner from Universiti Pertanian Bogor, Indonesia; as well as the Centre for Wildlife and Livestock Innovation, Faculty of Sustainable Agriculture, University Malaysia Sabah in Sandakan. "We believe the quality of the sperm was low, and that to continue the IVF treatment effort, we need to try and get sperm from rhinos in captivity in Indonesia.
It was previously believed that the poor quality of Tam’s sperm was a factor in similar failures in previous in vitro attempts. Experts in Sabah, however, will continue to collaborate with Indonesia in the pioneering efforts.
