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 ...

New research shows how sperm RNA changes as men age, revealing a biological shift that may affect reproduction and child ...

Researchers have uncovered a complex biological process that protects germ cells, the precursor cells to sperm, from genetic ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

Sperm cells have a monumental task, but their days are numbered. From the moment they're made in the testes to the time they may spend winding their way up the labyrinthine of the female reproductive ...

An artificial-intelligence tool honoured by one of this year’s Nobel prizes has revealed intimate details of the molecular meet-cute between sperm and eggs. The AlphaFold program, which predicts ...

Fathers exposed to high stress in childhood had different epigenetic markers that may affect their offspring, though more research is needed. When you purchase through links on our site, we may earn ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm production, new research has revealed. In a landmark study published today ...

An epigenetic study found that sperm DNA methylation changes with paternal age at thousands of genomic sites, including regions linked to autism. Age-related epigenetic shifts in sperm may help ...
