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, ...

A number of factors can play a decisive role in some couples' inability to conceive, which may lead them to turn to fertility treatments like IVF or IUI. But before couples get to that point, they ...

Human sperm have long been a subject of fascination—not just for their role in fertilization, but for their remarkable ability to navigate through some of the most viscous environments in the body.

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 at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

Scientists have boosted the motility of sluggish sperm by up to 266%, by blasting the cells with noninvasive, 40-MHz ultrasound waves to induce movement. Capturing the technique's impact on individual ...

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 ...
