Old newspapers reproduce thanks to IVF

The Smithsonian Institute for Biological Conservation (SCBI) at Front Royal found that the eggs of cheetahs are older (more than 8 years) good, allowing fertilization and delivering eggs to younger offspring to increase population. Cheetahs.

Analysis of hormones, eggs and uterus of 34 cheetahs in 8 research institutes, the results showed that leopards aged over 8 years developed abnormal, susceptible cells and cysts in the death zone. supply. This can prevent them from becoming pregnant, despite the fact that hormones and their eggs appear normal.

According to the study, about 80% of older newspapers living in North America have never spawned. It is estimated that there are only about 7,500 to 10,000 remaining leopards in the wild. They are listed as a highly endangered animal by the International Association for Conservation of Nature.

But the discovery will allow researchers to extract eggs from older female leopards, then fertilize and transfer the eggs to more young leopard cubs, to increase the population of newspapers.The lack of genetic diversity in the environment of captivity can lead to death, reduce resistance against disease for the cubs.

Over the next 2 years, researchers plan to extract eggs from a cheetah over 8 years old, then fertilize and deliver eggs to a smaller young leopard. If successful, the technique could one day apply similarly to wild panther to increase the population of cheetahs confined to new genes.

In addition, SCBI researchers can produce embryos from fresh cheetah eggs, hoping to do the same with frozen eggs.
