Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

Computer-assisted sperm analysis (CASA) systems have evolved over approximately 40
years, through advances in devices to capture the image from a microscope, huge increases …

A proper dialogue between spermatozoa and the egg is essential for conception of a new
individual in sexually reproducing animals. Ca2+ is crucial in orchestrating this unique event …

Dynamic tracking of human sperms across a large volume is a challenging task. To provide
a high-throughput solution to this important need, here we describe a lensfree on-chip …

Sperm require a sense of direction to locate the egg for fertilization. They follow gradients of
chemical and physical cues provided by the egg or the oviduct. However, the principles …

The shape of the flagellar beat determines the path along which a sperm cell swims. If the
flagellum bends periodically about a curved mean shape then the sperm will follow a path …

We develop a theoretical description of sperm chemotaxis. Sperm cells of many species are
guided to the egg by chemoattractants, a process called chemotaxis. Motor proteins in the …

Flagellar beating drives sperm through the female reproductive tract and is vital for
reproduction. Flagellar waves are generated by thousands of asymmetric molecular …

Simple Summary This review describes the mechanical and energetic processes which
underpin mammalian sperm motility as well as the mechanisms by which various agents …

Sperm are guided to the egg by a gradient of chemical attractants–a process called
chemotaxis. The binding of the chemoattractant to receptors on the surface of the flagellum …
