Clinical and Seminal Findings in Men with Sperm Antibodies

Abstract: A study was conducted to analyze the clinical and seminal findings in men with sperm antibodies in their blood and to relate these findings to the sperm antibody level the mucus penetration ability of the spermatozoa and fertility. 43 men with sperm antibodies in their blood were studied. Prostatovesiculitis was found in 37% (16) of the men. Of the 43 men 29 lived in sterile and 14 in fertile marriages. Sperm agglutination of the tail-to-tail type was found in most of the semen samples and in the majority there was also a low percentage of motile spermatozoa and a low degree of sperm motility without corresponding deviations of the other semen properties. There were statistically significant correlations between the immobilizing activity of the serum and the sperm motility degree in the ejaculates (-.57) and between the sperm agglutinin titre of the serum and the sperm agglutination degree in the semen (.42). An interrelation was found between high sperm antibody level in the blood decreased sperm motility in the ejaculate and sterility. It is concluded that the reduced motility and agglutination of spermatozoa in the ejaculates can be explained by the sperm antibodies present in the investigated males and the relationship between sperm antibodies at high levels in the blood and sterility might be due to reduced motility and penetration ability of the spermatozoa in the ejaculate. The high incidence of prostatovesiculitis in men with sperm antibodies and prostatovesiculitis which deserves further investigation.
