Scientists turn skin cells of infertile men into sperm precursors

WASHINGTON: US researchers said Thursday they have successfully coaxed stem cells made from the skin cells of infertile men into producing the precursors of sperm cells.

In a study published in the U.S. journal Cell Reports, the researchers said they took skin cells from infertile men and converted them into the so-called induced pluripotent stem cells ( iPSCs), which theoretically have the ability to generate all cell types found in the body.
