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

The testes are where sperm cells are produced and are also responsible for the production of the sex hormone testosterone. The testes, commonly referred to as "balls," are housed in a pouch of ...

Two new 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 as two papers in Nature Structural ...

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 ...

"These cells co-develop together, just like they would in an actual embryo, and establish that history of being neighbors," ...

Sperm formation is a highly complex process that involves many changes to the cell structure, such as shrinking of the nucleus, generation of a sperm tail, and remodeling of the sperm head.

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 ...

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 ...

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 ...

Researchers found that TEX38 and ZDHHC19 co-localize on the plasma membrane of spermatids and mediate S-palmitoylation of ARRDC5, a crucial protein for spermatogenesis. Disrupting either TEX38 or ...

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 ...
