In China, scientists have grown sperm in the laboratory. Male germ cells were created in the artificial conditions by means of which mice were subsequently inseminated. The experiment was successful and there was brought ultimately healthy offspring.
Spermatids were managed to grow from the stem cell by research team, led by Xiao-Yang Zhao. They hoisted 191 fertilized egg to female rodents. As a result 9 completely healthy mice have appeared, that are also able to acquire offspring in their reproductive age.
This method, according to scientists, will help to deal with male infertility. Although this application, only mice were currently subjected to this experiment. Their biology of development, as we know, has fundamental differences with the human. Nevertheless, the scientists hope that the new testing method on humans is a matter of time.
