Effect of zinc on human sperm motility and the acrosome reaction
(1992)
This study has assessed the effect of zinc on human sperm motility and the acrosome reaction in vitro. Progressively motile human sperm were selected by swim‐up and by glass bead columns and then incubated in a medium in ...
ESCRT (endosomal sorting complex required for transport) machinery is essential for acrosomal exocytosis in human sperm
(Society for the Study of Reproduction, 2015-11)
The sperm acrosome reaction is a unique, regulated exocytosis characterized by the secretion of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal and plasma membranes. In ...
Acrosomal swelling is triggered by camp downstream of the opening of store-operated calcium channels during acrosomal exocytosis in human sperm
(Society for the Study of Reproduction, 2016-03)
Acrosomal exocytosis in mammalian sperm is a regulated secretion with unusual characteristics. One of its most striking features is the postfusion loss of the outer acrosomal membrane and the overlying plasma membrane as ...
Modulation of spermatozoon acrosome reaction

Kinetics of human sperm acrosomal exocytosis
(Oxford University Press, 2014-09-01)
The acrosome reaction is a unique event in the lifespan of sperm characterized by the exocytosis of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal membrane and the plasma ...
Studies of lysophospholipids related to the hamster sperm acrosome reaction in vitro
(1993)
Phospholipase A2 and lysophospholipids have been implicated in the mammalian sperm acrosome reaction. In this study we further investigated the role of this enzyme and lysophospholipids on the acrosome reaction of hamster ...
Sperm acrosome biogenesis and function during fertilization
(Springer-VERLAG BERLIN, 2016)
Over the last decades, acrosomal exocytosis (also called the “acrosome reaction”) has been recognized as playing an essential role in fertilization. Secretion of this granule is an absolute requirement for physiological ...
Transmission electron microscopy for characterization of acrosomal damage after Percoll gradient centrifugation of cryopreserved bovine spermatozoa
(Korean Society Veterinary Science, 2011-09-01)
The objective of this study was to characterize acrosomal ultrastructure following discontinuous Percoll gradient centrifugation of cryopreserved bovine sperm. Semen was collected from six bulls of different breeds and ...
