Did it "work" with mice? Ie. were the created eggs and sperm able to combine and start multiplying when put inside the appropriate part of a mouse?

That would be great, however the backlash from the more... conservative population will be equally huge, I guess :)

The work by Hayashi published last year had derived precursor egg cells, but the sperm was from normal mouse testes as usual. As described in the article, they did successfully create healthy offspring, though the success rate was very small.
