A team led by University of Osaka researchers has developed a technique to generate testes from mouse embryonic stem cells (ESCs) outside the ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

Scientists at Michigan State University have uncovered the molecular “switch” that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team ...

An innovative treatment could one day help restore fertility in men who do not have the capability to produce sperm, such as cancer survivors or those with certain genetic disorders. Scientists have ...

Therapeutic mRNA delivered via lipid nanoparticles restored sperm production in genetically infertile mice and produced live ...

Imagine a future where a diagnosis of untreatable male infertility is no longer the end of the road—because science has found a way to produce human sperm from lab-engineered testicular tissue. This ...

Using the blastocyst complementation method, we produced rat embryonic stem (ES) cell-derived sperm in testicular hypoplasia mice and successfully generated rat offspring. This method can provide a ...
