title: The relationship of sperm viability and concentration to serum-induced head-to-head agglutination of bovine spermatozoa.
abstract: Individual samples of bull semen were treated by filtration to remove immotile spermatozoa and by the addition of 10% heifer serum. There was significantly (P less than 0.01) greater serum-induced agglutination in the filtered than in the unfiltered samples. Head-to-head agglutination was also greater (P less than 0.01) in dilute sperm suspensions when compared to concentrated sperm suspensions.
