Abstract
A method for evaluating sperm fertility. The method includes the steps of obtaining a sample of sperm from an animal of a species; staining the sample with a fluorescent DNA-binding dye; collecting at least one image of the stained sample; determining an edge of a nucleus of at least one sperm within the stained sample in the at least one image; measuring an intensity of the DNA-binding dye within an area defined by the edge of the nucleus of the at least one sperm; determining an average intensity per unit area of the area defined by the edge of the nucleus of the at least one sperm; comparing the average intensity per unit area to an average intensity per unit area for high-fertility sperm and low-fertility sperm of the same species to determine if the sample has high or low fertility.
