[Late sequelae after testicular torsion]

Thirty-five patients were examined six to eleven years after having been operated for torsion of the testis. Loss of testicular tissue was significantly associated with long preoperative duration of symptoms and with a low postoperative spermcount. No indications of autoimmunization affecting fertility nor evidence of bilateral defects were found. Apparently the reduced semen quality following testicular torsion is a matter of lost testicular tissue more than impairment of the quality of the remaining tissue.
