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 ...

Naked mRNA administration in the testes rescues sperm function, demonstrating a potential therapeutic approach for genetic male infertility.

New research reports that summer is the best season for swimming — and not just in the pool. Turns out that sperm motility ...

“We were struck by how similar the seasonal pattern was in two completely different climates,” said professor Allan Pacey.

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such ...

A new mathematical model predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells' motor activity and ...

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.

Reproductive biologists have identified the mechanism that triggers sperm's race to the egg, reports a study in Cell today. Stained sperm cells (Blue, nucleus; red, mitochondria; green, Hv1 protein ...

Michigan State University scientists are aiming to make the male fertility process easier by promoting non-hormonal based treatment. The difficulty is the sperm requiring sudden demand for energy ...
