Scientists from the University of Edinburgh and elsewhere have identified a novel gene that works as part of a pair to protect male fertility. Understanding how the two genes work together could ...

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 ...

As we age, our cells accumulate DNA mutations. If any of these mutations confer a growth advantage to a self-renewing or long-lived progenitor cell, its lineage can expand. The progenitor cells that ...

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 ...

In-vitro gametogenesis, or IVG, is a concept that sounds like science fiction but is slowly becoming a real possibility. Imagine creating eggs or sperm from skin cells, all outside the body. It’s a ...

Discovery of a pair of genes that work in perfect harmony to protect male fertility, could provide new insights into some unexplained cases of the most severe form of infertility, research suggests.
