French scientists for the first time in the world were able to obtain artificial human sperm in the laboratory. On the creation of sperm in a test tube, said representatives of the French company Kallistem, reports The Independent.

Kallistem said it had received full-fledged spermatozoa from undeveloped spermatogonia - stem cells taken by biopsy from the testes of patients.
Previously, this procedure was successfully performed only on mice. Now scientists are going to verify its safety on pre-clinical trials, and in 2017 they promise to give birth to a child from a man suffering from infertility (taking his spermatogonial cells and raising spermatozoa from them for in vitro fertilization).
Spermatogenesis (sperm formation) takes about 72 days in a person - this is a very complex process, and many violations in it lead to infertility. If successful, its technology Kallistem expects to help at least 50 thousand patients a year and take a monopoly position in the market in the amount of two and a half billion dollars.
However, prior to the publication of the patent on its process (scheduled for June 23, 2015), the company refuses to disclose its details. About the invention not a single article in peer-reviewed scientific journals All this caused skepticism in the academic world.
“Statements similar to what Kallistem has done cause mental anguish to many spouses. They have hope - and after a few years dies, when the new method does not reach the stage of a real clinical procedure,” said University Professor at Sheffield University Alan Pacey.
