Contralateral testicular blood flow was measured by the intratesticular injection of 133Xe in 9 controls (Group 1) and in 34 adult male albino rats with experimentally induced left testicular torsion. In Group 2 (n = 9) testicular torsion was maintained for 3 h; in Group 3 (n = 7) torsion was maintained for 9 h and in Group 4 (n = 10) for 15 days. In Group 5 (n = 16) torsion was maintained for 9 h in 8 rats and the sera were given to 8 normal animals. In Groups 3, 4 and 5 there was a significant increase in contralateral testicular blood flow on the fifteenth day. This increase may be the cause of contralateral testicular damage in prolonged unilateral testicular torsion.
