A reappraisal of the factors involved in in vitro initiation of the acrosome reaction in chicken spermatozoa

, 2008
International audienceChicken spermatozoa may remain in the female oviduct for a prolonged period before induction of the acrosome reaction on contact with the inner perivitelline layer (IPVL).

Effects of pentoxifylline treatment before freezing on motility, viability and acrosome status of poor quality human spermatozoa cryopreserved by the liquid nitrogen vapor method

Brazilian Journal of Medical and Biological Research, 2007
The objective of the present study was to investigate the effects of the direct addition of pentoxifylline (PF) to the ejaculates of men with poor sperm quality before freezing on post-thaw sperm motility, viability, acrosome integrity, and agonist ...

Effect of anti-p14 antibody on caprine sperm acrosome reaction.

, 2013
Acrosome reaction was induced by calcium ionophore A23187. Assays were performed using sperm collected from at least four different testis samples. Control values in absence of ionophore were 22.66±3.05.

Table_1_Glycogen Synthase Kinase-3 Regulates Sperm Motility and Acrosome Reaction via Affecting Energy Metabolism in Goats.DOCX

, 2019
Hyperactivation and acrosome reaction of sperm are pre-requisite steps for fertilization. However, the hyperactivation and acrosome reaction are critically controlled through the phosphorylation of specific proteins.
