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 ...

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 ...

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

Human sperm have long been a subject of fascination—not just for their role in fertilization, but for their remarkable ability to navigate through some of the most viscous environments in the body.

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 ...

While men may be able to have children much later than women, doing so could come with an increased risk of inherited disease for their children. Researchers from the Wellcome Sanger Institute have ...

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 ...
