In vitro gametogenesis, the creation of eggs and sperm from skin cells, has been achieved in mice and is estimated to be 10-20 years away from human application.

“a real gamecher would be something like in vitro gamtoenesis, which is making eggs and sperm potentially from skin cells. So even if you run out of eggs, if we could take like a skin biopsy and you know reprogram that cell to make an egg, then potentially you know any where are we in that? Very early. I think we'll see it eventually. It's been done in mice. Um, so we're probably 10 to 20 years away.”
