ABSTRACT
In this study we investigated the presence of antisperm antibodies in the sera of neonatal and young calves up to the age of 120 days by indirect immunofluorescence assay (IIP) and the sperm-agglutination method. By IIP assay, anil IgG and ants IgM antibodies were detected. In the sera of neonatal calves, before colostrum ingestion, no anti-sperm antibodies were detected due to physiological agammaglobulinemia. Titer obtained values in two day old and older calves were different for native sperm cells and sperm cells previously suspended in TRIS egg yolk extender or Biociphos plus extender (IMV, France) indicating antigenic differences between them. Their liter increased with age. This study confirmed the higher sensitivity of the IIP assay. We have also confirmed the hypothesis that in calves, antisperm antibodies naturally occurring before puberty, are most probably the result of cross reactivity with microbial antigens.
