Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so. To figure out how they slither through substances that should, in ...

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 ...

New research reports that summer is the best season for swimming — and not just in the pool. Turns out that sperm motility may actually be higher at certain times of the year than others, a finding ...

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.

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 ...

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 ...

A study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn has shown that pH value is crucial for sperm motility in sea urchins and salmon. An increase in pH ...

Medically reviewed by Patricia Mikula, PharmD Key Takeaways CoQ10 helps improve egg and embryo quality in women undergoing ...
