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 studies uncover how DNA folding controls sperm cell development. Researchers identified proteins that rearrange genomic architecture, setting cellular memory and fate. This 3D genome mapping ...

Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...

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.

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 ...

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 ...

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

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 ...
