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 ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm ...

Chromosomes in egg cells within fetal ovaries must be spliced and sorted perfectly. A new landmark study from UC Davis shows how protecting Holliday junctions allows this to happen.

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm ...

Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ...

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.

New findings into DNA organization in eggs and sperm could explain why some embryos stall in development while others ...

Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm ...
