Fat, daughter of 32-year-old Najin, is now only donor left in program focused on artificial implantation developed embryos in another more many species of rhinoceroses.

An of the world’s last two northern white rhinoceroses are being withdrawn from a breeding program aimed at saving the species from extinction, scientists said.

Najin, 32, is the mother of fatu who is now the only donor left in the program, which aims to implant artificially developed embryos in another more abundant species of Rhino in Kenya.

There are no known living men and neither of the two remaining northern white rhinoceroses can carry a calf term. Scientists hope to implant embryos made from rhinoceroses’ eggs and frozen sperm from deceased males to surrogate mothers.

“This decision was reached after a in-deeply ethical risk assess, weigh up risks and opportunities for the individuals and the whole species die show this decision without alternative”, the Ol Pejeta Conservancy, home to the mother and daughter, said in a statement on Thursday.

“Recent ultrasound examinations had several smallbenign tumors in Najin’s cervix and uterus, as well as a large cystic structure in her left ovary,” said Ol Pejeta. “These findings may explain why egg collection was not as successful.” with hair as they have been with Fat.”

In Fatu’s case, there are “12 pure northern white rhinoceros embryos so far,” said David Ndeereh, the acting deputy director for research at the Wildlife Research and Training Institute, a Kenyan state agency.
