In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...
New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Embryonic reproductive cells reveal striking genomic architecture before development
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 ...
In our cells, our DNA carries chemical or 'epigenetic' marks that decide how genes will be used in different tissues. Yet in the group of specialised ...
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 ...

How long sperm lives inside and outside of the body
Sperm can live for up to five days inside the female reproductive tract. Outside of the body, sperm can live for up to an hour at room temperature. Sperm can survive for decades if properly frozen by ...
