A team of scientists from Kyoto University in Japan claims to have created a viable artificial sperm using stem cells. This scientific breakthrough could lead to the development of new treatments for infertility among men.
Producing sperm cells were placed in sterile mice, after treatment, they were able to produce offspring. If the same method will be effective in humans, thousands of infertile men can become fathers.
Stem cells of mouse embryos were transformed into primary sex cells that are responsible for sperm production. Previous experiments were not completed as successful offspring from them were born sick and suddenly died.
As a starting point, the sperm can be constructed by scientists from a piece of skin of a man or of particles of bone marrow. When Japanese scientists successfully completed trials in humans, treatment of male infertility will survive a real revolution, because this tool will help in almost all cases.
