\"\"What’s the News<\/strong>: For the first time in medical history, scientists have successfully grown mouse sperm in a laboratory. As Northwestern University cell biologist Erwin Goldberg<\/a> told New Scientist<\/a><\/em>, “People have been trying to do this for years.” It’s hoped that being able to grow sperm outside the testes will lead to improved fertility treatments for men.<\/p>

How the Heck<\/strong>:<\/p>

The concept is simple: Combine the right dosage of chemicals that will provide nourishment to testes in a petri dish. Actually finding the magic amount is a tedious process of trial and error.
First, the team genetically engineered mice<\/a> “so that a protein only present in fully grown sperm would fluoresce green.”
Next, the scientists extracted germ cells (which produce sperm) from the newborn mice testes, and put them in a bath of agarose gel, fetal bovine serum, testosterone, and other chemicals.
After about a month, they discovered that virtually half of the lab-grown sperm were glowing, indicating that they were fully grown.
They then used in vitro<\/em> fertilization to impregnate female mice, who eventually gave birth to fertile mice themselves. <\/p>

Context<\/strong>:<\/p>

Past attempts at lab-grown sperm weren’t very successful. Many of ...<\/p>
