DrudgeReport: "Sperm from mice stem cells offers infertility hope..."
Discover: "Worldwide First: Stem Cells Turned Into Sperm Turned Into Living Animals"
It's nice to see the comments on the Discover article immediately ask the question of whether a woman could make sperm or not. Of course it is possible, no one could say with certainty that it is not possible, but it's not a question of that. It's more a question of whether it is a good public policy to spend our extremely limited resources on it, and whether it should be allowed to be attempted at all. To those questions, we can answer definitively: No! It is wrong to make embryos from modified gametes. And making a sperm from a woman certainly modifies her gametes, it creates sperm that do not represent an actual person.
There are better ways to help prevent infertility than to make an industry that manufactures people.
