Sperm Created From Mice Stem Cells

July 10, 2006 — -- The BBC is reporting that scientists in Germany have not only grown sperm from the embryonic stems cells of mice, but that the sperm was capable of producing offspring.

While many of the offspring died early or had "abnormal growth patterns," the experiment was hailed as a breakthrough in the field of infertility.

"For the first time we have created life using artificial sperm. This will help us to understand how men produce sperm and why some men are unable to do this," professor Karim Nayernia of Georg-August University in Göttingen, Germany, told the BBC.
