Hyperactivated Motility in Sperm
Journal of Andrology, 1996The functions of hyperactivation may fit together to create the following scenario. Sperm that enter the oviduct bind to the mucosal epithelium. Near the time of ovulation, hyperactivation helps them to detach from the epithelium, escape mucosal pockets, and move through oviductal mucus.

Neurochemical control of sperm motility
Experimental Cell Research, 1972Abstract Spermatozoa appear to function as multi-subunit, single cell, excitable systems at least partially under acetylcholinesterase control. The motility of Arbacia sperm systematically exposed to a variety of agents which influence acetylcholine metabolism or cell membrane stability changed in a dose-dependent manner.

Motility, viability, and calcium in the sperm cells
Systems Biology in Reproductive Medicine, 2013Sperm cells are complicated in vitro models. Their viability is limited, and physiology is complex. The study of their properties is of great application in the animal production as viable and functional gametes are essential. It has been shown that the decrease of sperm cell viability parallels an increase of the reactive oxygen species (ROS ...
