Newcastle University scientists said on the 8th, they use human stem cells in the laboratory to create the "world's first artificial sperm."

University of Newcastle Research Group in the "stem cell research and progress," published in the journal article said that such use of human stem cells to create "artificial sperm" is fully mature, the sperm can be activities, the latest scientific achievements may be as early as 5 years will be used for in vitro fertilization. Researchers believe that the results of the study will bring hope to the treatment of male infertility. By then, tens of thousands of infertile men will have their own "genetic" children. The research team also released a video to support their conclusions.

However, the Newcastle University researchers in this latest study did not win the full house prize. Some scientists believe that the university create "artificial sperm" not entirely good development. They pointed out that those who cultivated the cells may have some genetic characteristics, but the real function of sperm compared with the molecular structure, as well as very different. In addition, the latest achievements also led to a number of moral and ethical controversy.
