Just because a sperm is a strong swimmer doesn't necessarily mean it has the right amount of DNA, Dr. Lisa Lee told Newsweek.

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 ...

Each sperm cell, or spermatozoon, is small and motile. The spermatozoon has a flagellum, which is a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell ...

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 ...

This sets up a new structure that cements the cell's future fate as a sperm cell. PC-uSPG lose a majority of ZBTB16 occupancy, with moderate effects on gene expression, Related to Fig. 3. Credit ...

The chromosomes of sperm cells are tightly packaged into a complex of DNA and protamines. Converting the chromatin from a nucleohistone to a nucleoprotamine structure may serve both biophysical ...

A key part of the fertility process involves IZUMO1, a protein on the surface of sperm cells, and JUNO ... the researchers analyzed the X-ray crystal structure of IZUMO1 as it came in contact ...

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 ...
