In a world first, scientists in Japan have created a baby mouse with two fathers. Instead of using an egg cell from a female, they were able to take a skin cell from one of the male mice and convert it into an egg. They then fertilized this with a sperm cell from the other male.
The research points toward the possibility of radical new treatments for infertile couples. It also suggests that someday in the future, a male couple could have a biological child together using a mixture of just their own DNA, and not a surrogate egg donor.
A surrogate would still need to carry the child.
“This is the first case of making robust mammal oocytes from male cells,” said Katsuhiko Hayashi, who led the work at Kyushu University in Japan.
Hayashi presented the results at the Third International Summit on Human
