Follow-up after torsion of the spermatic cord.

Fifty-two patients were examined 4-10 1/2 years after operation for torsion of the spermatic cord. The testicular salvage rate was 56%. Loss of testicular tissue was correlated to preoperative duration of symptoms. Serum testosterone concentration was found to be within the reference range. FSH was elevated in patients with the longest duration of symptoms (> 24 h), suggesting an impairment of testicular function in these patients. There were two our of 13 patients with a severe oligo-azoospermia, both had a previous orchiopexy for undescended contralateral testis.
