In an advance for treating male infertility, researchers transplanted a patient with his own sperm-forming stem cells that ...

In humans and many other animal species, sex is determined by specific chromosomes. How did researchers discover these so-called sex chromosomes? The path from the initial discovery of sex ...

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 ...

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 ...

A Yale-led research team has uncovered how a naturally occurring biological mechanism is able to prevent sperm cells from interacting with an egg, preventing fertilization. The discovery, found in ...
