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 often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics .. | Cell And ...

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 ...

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 ...

Researchers have uncovered a complex biological process that protects germ cells, the precursor cells to sperm, from genetic ...

Spermatogenesis depends on micronutrients because sperm cells show high sensitivity to oxidative damage caused by their lipid ...

(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 ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

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 ...
