Scientists in mainland China have successfully mass produced high-quality artificial sperm for the first time.
"Our man-made sperms cells can be used to generate an army of half-cloned mice with ease and efficiency. These half-cloned mice will fight on the frontline in battles against cancer and other genetic health issues, said professor Li Jinsong, lead scientist on the project with the Chinese Academy of Sciences Shanghai Institute for Biological Sciences.
Man-made sperm have been produced by scientists in labs around the world for years,but the quality of these sperm was a problem. For instance, only about 2 per cent of the fertilised eggs could develop into healthy half-cloned mice.
In their new paper, Lis team reported an improved method which increased the proportion of healthy mice to over 20 per cent.
Though he hoped the new technology could help cure human diseases under emerging genetic therapies, Li said the mass production of sperm would lead to an "ethical crisis" if it was applied to humans.
A 20 per cent rate for healthy breeds may be good enough for experimental animals, but not humans. If it is applied to human sperm it could lead to an 80 per cent death rate or defects at birth.

Chinese scientists edit genes to produce artificial sperm capable of creating 'army of half-cloned mice'
Here I Come To Save The Day!
About time they created artificial sperm. We’ve had the polyester blue dresses for half a century.
Man-made sperm cells?
Its ... ummmm ... not a new thing.

Someone at Monsanto thinks we are going to be eating mice?
Lesbian man-haters rejoice.
That’s why I couldn’t be a scientist. I would secretly clone an army of Stacey Dashes.
If you have 400 eggs, this means you get 8 embryos and 1-2 healthy mice.
If you have 400 human eggs, you’ll get around 40 kids via IVF.
Simply due to market forces, you’d see eggs used for IVF instead of cloning due to demand and profit potential.
