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 ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is ...

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.

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

Video of a new mathematical model that predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells’ motor ...

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 ...

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