Sperm cells are at their highest quality during summer months, a new study has found, although that doesn’t mean it will lead ...

Sperm cells are known to prefer cooler temperatures. For quite some time, a puzzling question for scientists has been: how do temperature-sensitive swimmers actually operate effectively within the ...

Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so. To figure out how they slither through substances that should, in ...

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 ...

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...
