Abstract

A method is provided for rapidly determining the ability of sperm to undergo the acrosome reaction, using fluorescence microscopy, light microscopy or color change on a dot blot assay to determine the relative percentage of acrosome reacted sperm. Sperm are capacitated through use of bromelain or other enzymatic substances capable of capacitating sperm, with the total incubation time required to induce capacitation as little as fifteen minutes, yielding sperm that are fully capacitated and show excellent motility, with as many as 80% of normal sperm consistently induced to acrosome react.
