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 ...

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 ...

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 ...

Nearly eight to 12 percent of couples all over the world face fertility issues, with male infertility accounting for almost 50 percent of the cases. 1 A common cause of male infertility is errors ...

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 ...

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.

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...
