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 ...

Gene expression related to fertilization, sperm motility, and sperm structure in the testes of Tle6 -deficient mice showed an overall increase. Together, the findings of this study highlighted the ...

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 ...

There are many potential causes of infertility, and it can be challenging to pin down just what the problem is when a couple is having trouble getting pregnant. Now, researchers show that a few key ...

A Utah biotech startup says it has grown functional human sperm in a lab and used it to create early embryos—a development that, if validated, could dramatically expand options for men with severe ...

Nearly eight to 12 percent of couples all over the world face fertility issues, with male infertility accounting for almost 50 percent of the cases. 1 A common cause of male infertility is errors ...

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 ...

Researchers from The University of Osaka find that CFAP91 and EFCAB5 proteins are crucial for sperm motility, and that loss of function of either of these proteins reduces male fertility in mice Osaka ...
