Clinical characteristics of subfertile men with antisperm antibodies

This study investigated the clinical features which could serve as markers to identify subfertile men with antisperm antibodies including age, duration of infertility, history of abdominal or perineal surgery and previous genital trauma. Of the 162 men studied, 43 had a positive test for antisperm antibodies. A significantly greater number of these patients had a history of genital trauma and appendicectomy. Whereas the aetiological role of genital trauma in spermatozoal autoimmunity is readily explicable, that of appendicectomy is not. It can only be postulated that inflammation of the appendix may sometimes affect the vas deferens or that there is some inadvertent injury to the vas deferens during appendicectomy.
