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 sperms are incredibly important for our reproduction. It would therefore be easy to assume that we have detailed knowledge of their appearance. However, an international team of researchers has ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

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.

Failure of chromosomal organization within human egg and sperm cells result in miscarriages and infertility. However, the mechanisms controlling these processes are not understood. The discovery of a ...

The press release was prepared by Cell Press. Single-cell analysis of autopsied human testes suggests that abnormalities associated with aging sperm cells might be exacerbated by elevated body mass ...
