So far, researchers have only been able to use stems cell with the XY (male) chromosome to create ?in-vitro derived (IVD) sperm.? When scientists tried to create IVD sperm from cells with the XX (female) chromosome they weren?t able to move beyond early stage sperm. Guys, you may down, but you are not out yet. Even in the lab we still need the Y chromosome.
Beside, says Dr. O?Brien, a bunch of sperm from one line of stem cells means that the next generation would look a lot alike. Because the original stem cells came from one source, every cell created from them would have identical genetic material.
So what does the future hold if the research progresses? Will men actually become obsolete, at least from an evolutionary perspective? No way, says Dr. O?Brien. ?It?s kind of a far out idea. It makes me think of Wonder Woman and the island of the Amazons.? For now, it?s all test tubes, lab coats and hypotheses. ?Its application in real life is probably quite far in the future,? says Dr. O?Brien.
Since the technology is brand new and no babies have been conceived, let alone born, the mating game is still on.
