Mouse Sperm Successfully Grown in Lab, Researchers Say - Yahoo! News
Researchers report that they've grown mouse sperm from testicular tissue in the laboratory, a development that could advance the field of infertility in human males.
Although the findings only apply to mice, "this is a small but important step in understanding how sperm are formed, which may, in time, lead to us being able to grow human sperm in the laboratory," said Dr. Allan Pacey, senior lecturer in andrology at the University of Sheffield in England, who is familiar with the study results.
Sperm production is highly complex, the authors explained in background information in the study. Sperm previously created in a laboratory from mammal tissue didn't fulfill its purpose, Pacey said, noting offspring produced from it soon died.
