Pathophysiology of sperm motility
Frontiers in Bioscience, 2006Mammalian spermatozoa acquire the ability to swim during their transit from the testis to the oviduct under the control of several external and intracellular factors. These factors play also a pivotal role in regulating acquisition of hyperactivated motility and during the process of chemotaxis. This review summarizes the involvement of such factors in

To provide an alternative to presently available subjective ways of measuring sperm motility which often yield inconsistent data, we devised a method for determining sperm motile efficiency with it one can express objectively the amount of active sperm movement.

Hyperactivated Motility in Sperm
Reproduction in Domestic Animals, 2003ContentsHyperactivation is a movement pattern seen in sperm at the site and time of fertilization in mammals. It may be critical to the success of fertilization, because it enhances the ability of sperm to detach from the wall of the oviduct, to move around in the labyrinthine lumen of the oviduct, to penetrate mucous substances and, finally, to ...

AbstractThe flagellosperm of insects, although following a general ground plan, exhibit considerable variation in morphology and ultrastructure across taxa, consistent with a history of rapid and divergent evolution. Sperm competition, which occurs when sperm of two or more males compete for the fertilization of a female’s ova, has been recognized as a

Sperm motility in the presence of boundaries
Bulletin of Mathematical Biology, 1995The fluid dynamics of sperm motility near both rigid and elastic walls is studied using the immersed boundary method. Simulations of both single and interacting organisms are presented. In particular, we find that nearby organisms originally undulating with a 90 degree phase shift may adjust their relative swimming velocities and phase-lock ...

Urogenital infection and sperm motility
Andrologia, 2003Male accessory sex gland infections are considered as potential hazards to male fertility. Various pathophysiological concepts have evolved from experimental and clinical studies that begin to explain the effects of bacteria and immunological events on the function of spermatozoa and sperm motility in particular. Besides direct influences of pathogenic

Six different doses of caffeine were used to study its effect on human spermatozoal motility. The recently developed method for assessment of sperm motility by videomicrography was used to determine the percentage of sperm motility, swimming speed (velocity), percentage of progressive sperm, and progressive swimming speed.
