The study was planned with an objective to assess the level of antisperm antibodies (ASA) in the blood serum and seminal plasma of breeding cow bulls and their relationship with sperm function and fertility tests. ASA was analyzed in blood serum and seminal plasma by SpermMar test, Immuno peroxidase assay (IPA) and Enzyme linked immunoabsorbant assay (ELISA). In SpermMar test, about 54% bulls were with >40% IgG in blood serum against sperm surface antigens, whereas none of the bulls were with >10% IgG in seminal plasma. More than 20% and >10% IgA against sperm surface antigens were detected in the blood serum and seminal plasma of 65.8% and 37% bulls, respectively. Out of 26 bulls, seminal plasma of 21 bulls reacted with spermatozoa both in IPA and IgA latex particles and that of only 12 bulls reacted with IgG. In IPA, about 50% of the bulls had >40% ASA against head surface antigens, whereas, there were 23% bulls with >10% ASA in seminal plasma. Also ELISA indicated a higher antibody titre in blood serum (3200 - 6400) and seminal plasma (40 - 80) of 50% and 42% bulls, respectively. There were 11 bulls with low values of HOST/in vitro acrosome reaction/cervical mucus penetration assay and higher level of either serum or seminal plasma ASA. Our study revealed that a significant level of ASA in serum or seminal plasma may have effect on the fertility of bulls by affecting the sperm function.
