About 9% of men of reproductive age in the United States experience fertility problems. One of the many causes of male ...

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 ...

Once a sperm has broken through to an egg cell in order to fertilize it, the two cells need to hold together tightly. This occurs via a type of protein binding that is among the strongest in ...

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 ...

Lab-grown sperm could soon become a reality after scientists were able to create germ cells, the precursor to reproductive cells.

Researchers have decoded a long-standing mystery of how flowering plants ensure their sperm cells successfully reach the egg for fertilization, according to a recent study published in the journal ...

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 Nature ...
