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 ...

Add Yahoo as a preferred source to see more of our stories on Google. We often imagine sperm as swimmers, tiny cells whipping their tails to power through fluid on a mission toward the egg. However, a ...

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 ...

Two new studies uncover how DNA folding controls sperm cell development. Researchers identified proteins that rearrange genomic architecture, setting cellular memory and fate. This 3D genome mapping ...

The 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 ...

A new study shows that lab-grown sperm cells can be derived from stem cells. July 9, 2009 — -- The face of infertility-- in literature, in the media, in advocacy groups -- is so predominantly ...

Sperm cells are known to prefer cooler temperatures. For quite some time, a puzzling question for scientists has been: how do temperature-sensitive swimmers actually operate effectively within the ...
