Japanese scientists have made viable mouse eggs in a laboratory dish, an advance that may offer a new route for treating infertility in people.

The experiment completes a long-sought quest in reproductive biology: to make sperm and eggs in a lab dish. A year ago, the same core group of scientists at Kyoto University created healthy mouse sperm in the lab.

In the latest experiment, the dish-created eggs were fertilized with natural mouse sperm to create healthy, fertile mice. The research appears in the journal Science.
