Is this the end of sexual reproduction as we know it?

According to a study published Thursday in the journal 'Cell Stem Cell', Chinese scientists have created 'bi-maternal' mammal babies — babies with two mothers — and say they are healthy and can lead normal lives to reproduce naturally later on.

In the research conducted by Chinese scientists at the Chinese Science Academy, scientists took eggs from a female mouse and half-chromosome (23) embryonic stem cells from the second. Both mice had half of the cells needed to code the DNA, but it wasn't enough to just combine them, the scientists said

Using genetic editing technology, the scientists said they had to erase three DNA coding sequences to make these two different DNA sequences genetically compatible.

The leading scientist of the research team, Dr.Wei Li, stated "this result showed us what is actually possible scientifically: the errors in the genetic coding can be eradicated from mice bred with two mothers."

It wasn't the same case with mice with two fathers, the researchers pointed out, adding that they couldn't successfully breed. After just two days of coming into the world, the mice with two fathers did not survive.

Chinese genetic scientists said this extraordinary experiment took place while they were researching sexual reproduction and its phases. Babies with two mothers can actually lead a normal healthy life and can reproduce naturally after they complete adolescence, the research showed.

"To consider exploring similar technology for human application in the near future is implausible," said Dusko Ilic, a stem cell specialist at King's College London who was asked to comment on the Chinese results.

"The risk of severe abnormalities is too high, and it would take years of research in various animal models to fully understand how this could be done safely."
