Researchers see hope for infertile men

(NEWSER) - Researchers have managed to produce sperm cells from embryonic stem cells—and for the first time, the sperm worked, resulting in healthy baby mice. Researchers in Japan mixed the embryonic stem cells with certain proteins and hormones. They converted the resulting cells into germ cells, which they implanted in the testes of mice. There, they developed into working sperm, Discover reports. Researchers hope the discovery will lead to male infertility treatments, notes ScienceNow . More»

But Ted, and others like him, could also be “putting the public at risk,” one doctor tells DoubleX. More»

(NEWSER) - British scientists announced they have created synthetic human sperm for the first time, the Guardian reports. The sperm—grown in a lab from stem cells—swim, have tails, and exhibit many of the same biological characteristics of real sperm, according to researchers. They believe the breakthrough could lead to a better understanding of male infertility and its treatment. More»
