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 ...

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such ...

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 ...

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 ...

Spermatogenesis depends on micronutrients because sperm cells show high sensitivity to oxidative damage caused by their lipid ...

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 ...

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 ...

Sperm carry more than DNA. They carry a complex network of lipids that guide energy use, membrane fluidity, motility, and the ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...
