Quest to create viable human sex cells in lab progressing rapidly, with huge implications for reproduction

Scientists are just a few years from creating viable human sex cells in the lab, according to an internationally renowned pioneer of the field, who says the advance could open up biology-defying possibilities for reproduction.

Speaking to the Guardian, Prof Katsuhiko Hayashi, a developmental geneticist at the University of Osaka, said rapid progress is being made towards being able to transform adult skin or blood cells into eggs and sperm, a feat of genetic conjury known as in-vitro gametogenesis (IVG).

His own lab is about seven years away from the milestone, he predicts. Other frontrunners include a team at the University of Kyoto and a California-based startup, Conception Biosciences, whose Silicon Valley backers include the OpenAI founder, Sam Altman and whose CEO told the Guardian that growing eggs in the lab “might be the best tool we have to reverse population decline” and could pave the way for human gene editing.

    People would have lots of kids if each subsequent child didn’t make their existing family’s life much more difficult

      People used to have 5+ kids and it was considered fine. It’s a cultural thing.

        The culture is linked to the income. People have more kids in poorer countries because they typically don’t have a social safety net so the only way to survive in old age is by having lots of children. When the countries become richer and get social security they start having less kids, especially when kids become a financial burden
