Lab-grown sperm and eggs just a few years away, scientists say

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.

His own lab is about seven years away from the milestone, predicts Hayashi .

Other frontrunners include a team at Kyoto University and a startup, Conception Biosciences , whose Silicon Valley backers include OpenAI founder, Sam Altman .

Most believe that years of testing would be required to ensure the lab-grown cells are not carrying dangerous genetic mutations that could be passed on to embryos and any subsequent generations.

Some of the mice born produced using lab grown cells have had normal lifespans and been fertile.

The Human Fertilisation and Embryology Authority is grappling with how the safety of lab grown eggs and sperm could be ensured.
