Biological Reviews, 2008
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

Andrologia, 2009
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.

Polyamines modulate mouse sperm motility
Systems Biology in Reproductive Medicine, 2023Polyamines are polycationic molecules which contains two or more amino groups (-NH3+) highly charged at physiological pH, and among them we found spermine, spermidine, putrescine, and cadaverine. They interact with proteins, nucleic acids, modulate Ca2+, K+, and Na+ channels, and protect sperm from oxidative stress. In this work, we evaluate the effect

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

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 ...

Metabolism of motile zebrafish sperm
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2011As metabolism of motile fish sperm is not well understood, the current study examined the metabolism of saline-activated zebrafish (Danio rerio) sperm. Activation of sperm with inhibitors of oxidative phosphorylation (potassium cyanide, 2,4 dinitrophenol or carbonyl cyanide 3-cholorophenylhydrazone) negatively impacted sperm motility by 60-90 s ...
