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 ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

(BOSTON) — More than one-sixth of adults around the world experience infertility in their lifetime. There is a high unmet need not only for increased access to affordable, high-quality fertility care ...

Germ cells pass DNA to the next generation and undergo massive reorganization of their DNA packaging to generate totipotency, or the ability to differentiate into any cell type. Understanding the ...

A new study shows that lab-grown sperm cells can be derived from stem cells. July 9, 2009 — -- The face of infertility-- in literature, in the media, in advocacy groups -- is so predominantly ...

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 ...

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 earliest days of pregnancy depend heavily on the health of the egg and sperm. Week 3 marks the stage when fertilisation occurs, and rapid cell division begins. Egg and sperm quality influence how ...

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 ...
