Scientists have fertilized eggs of Northern White Rhinos after Sudan, the last male rhino, died in 2018. This process might save the rhinos from extinction!
White Rhinos are on the brink of extinction. After the last male rhino named Sudan, died last year, scientists tried finding ways to help save the species.
Wildlife conservancy, Ol Pejeta reported on Twitter that they successfully harvested “10 eggs from the world’s last two northern white rhinos, Najin and Fatu, 7 eggs (4 from Fatu and 3 from Najin).”
They elaborated that the eggs have “successfully matured and artificially inseminated with frozen sperm from northern white rhino bulls, Suni and Saut.”
Cesare Galli was in charge of the procedure. He also said, “We were surprised by the high rate of maturation achieved as we do not get such high rate with southern white rhino females in European zoos.”
Continuing further, “The semen of Saut was very difficult to work with. And to find three live sperms needed for the eggs of Najin we had to thaw two batches of semen”.
“Now the injected oocytes (cells) are incubated,” Galli also said. “And we need to wait to see if any viable embryo develop to the stage where it can be cryo-preserved for later transfer”.
The female rhinos Fatu and Najin, are Sudan’s daughter and granddaughter, respectively. After his death, a representative of Ol Pejeta, Elodie Sampere, made a statement. She said, “His personality was just amazing and given his size, a lot of people were afraid of him. But there was nothing mean about him.”
According to World Wild Life, White Rhinos status is “near threatened”.
