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 ...

Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity ...

According to research from a team at the University of Utah Health and the University of Nevada, Reno School of Medicine, ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers 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 research shows how sperm RNA changes as men age, revealing a biological shift that may affect reproduction and child ...

Scientists might soon be able to create eggs and sperm from skin and blood cells. What will that mean? The way we make babies could be about to change. Maybe. An embryo forms when sperm meets egg. But ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is exposed to stress or toxicants, can lead to metabolic and behavioral ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...
