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 from Monash University have discovered that using high-frequency ultrasound can boost the motility of sperm, potentially increasing a couple’s chances of conceiving. In a world first study ...

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 ...

Researchers develop a novel Tle6 gene hetero knockout mice model to understand the role of this gene in male fertility and find that its deficiency results in abnormal sperm structure, reduced sperm ...

The female genital tract can be a hostile environment for conception. Out of about 100 million sperm, only a few hundred make it to the fallopian tubes. Guided by a directional movement called ...

About 120 million unintended pregnancies occurred each year between 2015 and 2019 worldwide. While there are oral contraceptives for women, the development of oral contraceptives for men has not been ...

Sperm doesn’t shift into high gear in mammals just to show off, new research shows. It originally needed that extra speed to break the egg barrier. Later on, evolution enabled sperm to use its ...

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 ...
