Abstract
Recent claims that bull sperm display chemotaxis to synthetic peptides known to be chemotactically active for neutrophils are not based on direct observation of sperm behavior. When these observations are made, no change in sperm motility or direction is seen. The supposed chemoattractant effect is probably based on disruption by the peptides of the sperm acrosome, resulting in increased sperm adhesion to the glass surface inside the pipette containing the supposed chemoattractive peptide.
