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 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 ...

A novel screening system enables researchers to investigate sperm cell development and health at the molecular level. The new approach promises breakthroughs in male contraception and infertility ...

Unlike the widely known biological clock in women, male reproductive aging has often been overlooked. Public and medical narratives have long portrayed sperm quality as relatively unaffected by age, ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

New research shows how sperm RNA changes as men age, revealing a biological shift that may affect reproduction and child ...

For decades, sperm were thought to become fully active the moment they entered the female reproductive tract. New research suggests otherwise. A temperature-sensitive switch inside sperm cells may ...

Hidden RNA signals in sperm reveal an "aging cliff" that could impact offspring health.
