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 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, ...

This article was reviewed by Darragh O’Carroll, MD. Key Takeaways: After a vasectomy, sperm production doesn’t stop — but ...

Scientists at Michigan State University have uncovered the molecular “switch” that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team ...

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, ...

How long sperm can live outside of the body that has produced them depends on several factors. When sperm have been deposited inside the female reproductive tract (vagina, uterus, and fallopian tubes) ...

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 ...
