Scientists are getting closer to removing men from the conception equation, announcing yesterday that they have produced early-stage sperm cells from male bone marrow. Now the team of British researchers is seeking ethical approval to try the same thing with women.
Skeptics point out that there is a huge jump from a primitive sperm cells to a fully functional swimmer. But success could be a boon to infertile couples, as well as lesbian couples who want to have children together. "The problem is whether the sperm cells are functional or not," says researcher Karim Nayernia. "I don't think there is an ethical barrier, so long as it's safe."
