The northern white rhinoceros species, which has been roaming the earth for 55 million years, is on the verge of extinction

Reproductive attempts with IVF and stem cell techniques failed

With the death of the last male 3 years ago, only two females survive: the white rhinoceros that survived the ice age, the earthquake, the meteor

Nairobi: The Northern White Rhino, a species that has existed on Earth for 55 million years, is on the verge of extinction. The white rhinoceros, which has withstood centuries of ice age, earthquakes, meteor showers, and various changes on Earth, has not survived.

Only two females, Nazin and Fattu, survive after the world's only white male rhino named Sudan died on March 19, 2018 at Kenya's All Pejeta Zoo.

A kilo of white rhino horn fetched હજાર 50,000 in the international market. So the human activity of killing these rare rhinos and getting their horns has wiped out this animal which has existed for millions of years.

According to one source, the number of white rhinos in the north was around 20,000 in 1970, which dropped to only 400 in 1990. In 2003, only 32 rhino populations survived. These white rhinos were previously found not only in northwestern Uganda, South Sudan, the northeastern part of the Congo in Central Africa, but also in Chad and Cameroon.

Despite such large-scale hunting of white rhinos, no efforts were made to stop it. That's why the last two surviving females of this species of rhinoceros live a lonely life in a zoo 250 km from Nairobi, Kenya.

After the death of the male rhinoceros 3 years ago, zoologists and scientists hoped to save the white rhino species by cloning and IVF techniques.

But 29-year-old Nazin and 19-year-old Fattu, the final heirs of the endangered species, have reportedly been unable to conceive artificially, raising hopes of saving the northern white rhinoceros species. Attempts to mate naturally with these females were unsuccessful when the last male of this species of white rhino, Sudan, was alive.

It cost 90 9 million to save this rare species of white rhino

In late 2015, scientists devised a breeding plan using stem cells to save the northern white rhino species. In Berlin and San Diego, the DNA of about a dozen northern white rhinos was already stored in a genetic bank.

At the end of August 2019, a white rhinoceros was artificially inseminated in the uterus of Nazin and Fatu by collected sperm.

From December 2020, renewed efforts for fertility began with the collected semen of a dead white rhino named Sudan. After the death of the last male, scientists made similar attempts at artificial insemination, but without success, this unique species, which has existed for millions of years, is on the verge of extinction. It has cost 90 9 million so far to save the endangered white rhino species.
