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 ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...

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 ...

The latest study from the Sharma Lab makes the mechanisms of how epigenetic information is established in sperm cells, and how that encoding affects offspring health, a little less of a scientific ...

CHICAGO (Reuters) - U.S. researchers have found a way to coax human embryonic stem cells to turn into the types of cells that make eggs and sperm, shedding light on a stage of early human development ...

Scientists warn that storage may cause sperm to lose quality over time, raising new concerns about fertility and conception ...
