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 ...

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 ...

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.

The results of the largest study of its kind have been presented at the 38th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE). The study analyzed 5335 intrauterine ...

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 ...

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 ...
