Rat testicle cells that were frozen for 23 years have produced sperm after being implanted into mice. The findings suggest that children who have testicle tissue frozen before cancer treatment may be ...

Researchers have created lab-grown testicle organoids that closely resemble the real thing. The breakthrough provides a promising model for research that may advance our understanding of the organs' ...

The press release was prepared by Cell Press. Single-cell analysis of autopsied human testes suggests that abnormalities associated with aging sperm cells might be exacerbated by elevated body mass ...

More than a decade ago, scientists succeeded for the first time in generating primordial germ cells—the precursors of sperm and eggs—from embryonic stem cells, a process that led to functional sperm ...

Rat sperm cells generated from stem cells in the lab have been used to produce fertile offspring for the first time. The approach could be adapted to rescue endangered rodents and may help to inform ...
