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, ...

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, ...

The day when human sperm and eggs can be grown in the laboratory has inched a step closer, with the discovery of a way to recreate a crucial developmental step in a dish 1. “Epigenetic reprogramming ...

Sperm cells have a monumental task, but their days are numbered. From the moment they're made in the testes to the time they may spend winding their way up the labyrinthine of the female reproductive ...

Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ...

India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.

CHICAGO (Reuters) - U.S. researchers have found a way to coax human embryonic stem cells to turn into the types of cells that make eggs and sperm, shedding light on a stage of early human development ...

Scientists have identified an RNA-based sperm aging clock driven by rsRNA length changes, which may help assess paternal reproductive risk and offspring health.
