Phosphoinositide-dependent pathways in mouse sperm are regulated by egg ZP3 and drive the acrosome reaction

open access: yes, 2007
Sperm of many animals must complete an exocytotic event, the acrosome reaction, in order to fuse with eggs. In mammals, acrosome reactions are triggered during sperm contact with the egg extracellular matrix, or zona pellucida, by the matrix glycoprotein

Acrosome reaction in morphologically different types of human spermatozoa

open access: yes, 2011
Background: The aim of our study was to ascertain if the acrosome functionality differs between various morphological types of spermatozoa in human. Methods: Fourteen ejaculates were resuspended in the culture medium with the aim to wash the spermatozoa ...

The pH of the hamster sperm acrosome.

open access: yes, 1978
The pH of the hamster sperm acrosome was estimated by a method based on the distribution of monoamines between membrane enclosed volumes maintaining pH gradients. A fluorescent amine, 9-aminoacridine, was used to permit both microscopic and fluorometric

Improved methodology for the detection and quantification of the acrosome reaction in mouse spermatozoa. [PDF]

open access: yes, 2009
This study evaluates the use of two fluorescein-labelled (FITC) plant lectins, Pisum sativum (edible pea) agglutinin (PSA) and Arachis hypogaea (peanut) agglutinin (PNA), in order to determine the most accurate and reliable method to experimentally ...

Genistein\u27s Effect on Acrosome Reaction of Ram Sperm

open access: yes, 2011
Capacitation and acrosome reaction are important processes that sperm cells must undergo in the female reproductive tract in order for fertilization of the ova to occur. Genistein, a phytoestrogen, has been shown to inhibit protein tyrosine kinase (PTK)

Modulation of spermatozoon acrosome reaction

open access: yes, 2011
Spermatozoon acrosome reaction is an exocytotic event of the utmost importance for the development of mammalian fertilisation. Current evidence shows that the triggering of the acrosome reaction (AR) could be regulated by the action of diverse compounds,
