ELI5: Why can't scientists artificially impregnate near-extinct species to help ensure the survival of the species?
gpt
They are doing this as an attempt to save them. But there are issues.

Artificial impregnation does not always work. With some species like Rhinos it fails far more than it works. 

Some species have bad/dangerous pregnancies when in captivity. 

Some species abandon the young if they were from artificial insemination, or do so just in general and the young do not survive. 

And you still have the problems of small gene pools causing genetic disorders.
