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 ...

If you walked into a modern operating theater today, you might see a surgeon sitting at a console, guiding robotic arms with calm precision. It already feels futuristic. Smaller cuts, ...

Add Yahoo as a preferred source to see more of our stories on Google. Fathers may carry traces of their childhood trauma in their sperm cells, a new study finds. The new research, published Jan. 3 in ...

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 ...

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.

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 ...
