Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by ...

Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable ...

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 ...

Ultrastructure expansion microscopy revealed that defective centrioles hinder sperm motility by impeding flagellum formation ...

A functional sperm tail is essential for successful reproduction. Defects in its development often lead to infertility. This is also shown by a recent international study involving researchers from ...

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 ...

Sperm are highly specialized cells adapted to achieve a single goal: fertilize an egg. Along the road to fertilization sperm must embark on a lengthy journey to the female oviduct, avoiding several ...

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 ...
