“We brought ten oocytes back from Kenya, five from each female. After incubation seven matured and were suitable for fertilization,” Cesare Galli, a professor based at the Avantea Laboratories in Cremona, Italy, said in an emailed statement. Sperm from two deceased males, Suni and Saut, were injected into the eggs, of which two developed into viable embryos.
The embryos, all from Fatu’s eggs, will be transferred to a surrogate mother, according to the statement. Najin’s eggs didn’t make it.
“Global human behavior still needs to radically change if the lessons of the northern white rhinos are to be learned,” said Richard Vigne, managing director of Ol Pejeta Conservancy, where the two rhinos are sheltered.
