Men Not Needed to Create Sperm - Finally, proof that the male of the species is superfluous: scientists at the University of Newcastle have created human sperm cells from female embryonic stem cells. Coming research....I didn't intend that pun...will focus on creating sperm from female bone marrow, a less controversial source.
But this technique would only produce a female egg, right?
Actually, current efforts won't produce a viable egg at all. Before that can happen, the researchers must figure out a way to induce the cells to undergo meiosis, which would give the diploid cells the correct amount of genetic material.
