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 ...

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 ...

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 ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...

The image shows centromeres (white) at the edge of the nucleus (blue) shortly before meiosis begins in a mouse germ cell (Huang et al., 2026). In our cells, our DNA carries chemical or ‘epigenetic’ ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...
