Israeli scientists have grown sperm in the laboratory.

To do this, they cultivated testicular cells in a medium that mimics the natural one. Experiments on mice were successful - during the tests, sperm appeared in immature males after a month and a half. The technology may in the future become part of a therapeutic strategy to combat male infertility and preserve reproductive function in boys who undergo aggressive chemotherapy or radiation therapy during puberty. These are not the first scientists to grow sperm in the lab. Similar work is underway in different countries. It is important whose technology will be the most efficient, simplest and cheapest.
