Rat sperm cells generated from stem cells in the lab have been used to produce fertile offspring for the first time. The approach could be adapted to rescue endangered rodents and may help to inform the artificial production of human sperm to treat infertility.
Until now, cells that give rise to sperm and egg cells, called germ cells, have only been produced in the lab in mice.
Toshihiro Kobayashi at the University of Tokyo and his colleagues have now shown that stem cells extracted from rat embryos can be grown in the lab to produce germ cells that form sperm when implanted into rat testes.
However, rats and mice are more similar to each other than humans, and the artificial production of human sperm and eggs may be several decades away.
“Humans and non-human primates have different modes of [germ cell development] and a much longer developmental timeline. So generalisation of the result to other species might not necessarily be straightforward,” says Kotaro Sasaki at the University of Pennsylvania in Philadelphia.

Interesting!
So, I'm guessing that the sperm convey the DNA from the embryo, not of the male with the implanted cells in their testes. good news (eventually) for men with low sperm count...I guess?

Good news for some.
A pathway to conception by removing those toxic males completely out of the chain.
"Mommy....who was my daddy?"
"..............................................."
Best start thinking on ways to explain the miracles of cellular biology and hyperplasia to toddlers.
