title: [The importance of the presence of antisperm antibodies in serum and ejaculate of men with infertility].
abstract: There are multiple insults to the male genital tract that have been associated with an increased risk of antisperm antibodies (ASA) formation. The presence of ASA has been regarded as typical and specific for the immunological infertility. It has been suggested that the presence of agglutinated spermatozoa is suggestive of the existence of an immunological cause of infertility such as the existence of ASA.
  
  
  OBJECTIVE
  The objective of this study was to determine the clinical significance of serum and seminal plasma ASA as well as whether varying degrees of sperm agglutination can be a predictive indicator of positive serum and/or seminal plasma ASA.
  
  
  METHODS
  100 infertile and 30 fertile men were tested for ASA in seminal plasma and serum. The evaluation of patients included complete history, physical examination, scrotal ultrasound and semen analysis. ASA in serum and seminal plasma were tested by ELISA (Biosource, Belgium) and results were compared with the data of the semen analysis.
  
  
  RESULTS
  44 (44%) of the patients tested positive for ASA in seminal plasma, 9 of them had positive serum ASA. In the control group, seminal plasma ASA were not detected and two men (6.7%) tested positive for serum ASA. Correlation was established between seminal plasma ASA and two of the semen analysis markers: agglutination and increased viscosity.
  
  
  CONCLUSIONS
  ASA in seminal plasma are much more predictive than ASA in serum and have major role in the pathogenesis and diagnostics of male infertility.
