Molecular mechanism uncovered in mice by UC Santa Cruz researchers reveals how a father’s diet, stress, and other ...

Human reproduction requires both male and female gametes. Gametes are special sex cells that contain the genetic information necessary to create a new life. Men produce millions of gametes called ...

DALLAS – Nov. 15, 2005 – New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like ...

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 ...

A novel screening system developed at Kyoto University enables researchers to investigate sperm cell development and health at the molecular level. The new approach, published in Cell Genomics, ...

Video of a new mathematical model that predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells’ motor ...

Sperm – in theory, you only need one good one to get the job done. Nevertheless, the average pair of human testicles is estimated to crank out about a trillion of these little cells over a lifetime, ...
