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 ...

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.

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 ...

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 ...

The latest study from the Sharma Lab at UC Santa Cruz makes the mechanisms of how epigenetic information is established in sperm cells, and how that encoding affects offspring health, a little less of ...
