The northern white rhino which is nearly extinct, the scientists are trying their best to revive the species. They have come up with the idea of human test-tube baby techniques in order to save the species.
Using dead males, two infertile remaining females, and some closely related southern white rhinos, the scientists are trying an improbable experiment to revive an entire subspecies
They also have an alternative plan by using stem-cell technology to create a population of pure northern white rhinos in the lab.
A technique called intracytoplasmic sperm injection or ICSI was used by a European team of researchers to create a few early-stage rhino embryos. The sperm of the last northern white rhino males was used before they died.
Regarding IVF plans for Northern white rhinos, BBC wildlife presenter @michaelastracha says “I think it’s crazy. I think we should definitely put our money into things that we can save and environments that we can save" https://t.co/gVwdn1AVhB

The eggs cells from female southern rhino subspecies were injected with the sperm then these egg cells will develop into the embryo. A handful of embryos could potentially be implanted into surrogate rhino mothers.
Sudan, the world’s last male northern white rhino is no more resulting it to the extinction of northern white rhino. The experiment is possibly the first step to recreate an extinct subspecies which would be a hybrid- half northern and half southern white rhino, reported in the journal Nature Communications.
Poaching and war in the countries of Chad, Sudan, Uganda, Congo and Central African Republic has driven the Northern white rhinos to extinction.
Thomas Hildebrandt of the German Leibniz Institute for Zoo and Wildlife Research in Berlin along with his colleagues in the Czech Republic and Italy, as well as in Japan, used the same techniques to help infertile humans and started an effort to create new white rhinos in the lab.
“We didn’t have many options so we had to be realistic.”
They’ve succeeded in their first endeavour in creating hybrid embryos. “These are the first in-vitro produced rhinoceros’ embryos ever. They have a very high chance to establish a pregnancy once implanted into a surrogate mother,” Hildebrandt said in a statement.
The last two female northern white rhino living under guard at a sanctuary in Kenya is expected to be used for harvesting egg cells.
The early embryos called blastocysts have been frozen which is expected to be implanted their embryos into the more common southern white rhino females and then breed any resulting rhinos to try and concentrate their northern white rhino genes.
Why rhino’s sad demise may not mean extinction for his species
This procedure may not be able to save the whole subspecies. So, the team of scientists are cloning technology using stem cell and to try to make pure northern white rhinos.
