Creating sperm or egg cells in the laboratory has been tried several times in the past few years. The reasons for this range from a better understanding of the fundamentals of the reproductive process, to helping infertile couples with their child-wish. The attempts, using embryonic stem cells, however, did not yield viable germ cells.Until now.A research team at Kyoto University has succeeded in turning mouse embryonic stem cells into viable sperm precursor cells.
