[Fertility after experimental torsion of the spermatic cord (author's transl)].
In groups of 10 specimens the testicles of 100 Wistar rats were half unilaterally half bilaterally rotated 720 degrees and retorted 1, 2, 4, 6 and 8 hours after torsion. The fertility rate was investigated by copulation experiments following experimental torsion of the spermatic cord. Fertility was demonstrated by pregancy. Independently of torsion period the fertility rate of unilateral contorted specinens was 60% -- like in both control groups. The bilaterally contorted animals were fertile in 40% from the 1 h -- group and in 30% from the 2 hours -- group. If the torsion period was longer than 2 hrs. bilaterally conterted animals were infertile in all cases. There is no influence of unilateral conterted testicle on contralateral uncontorted testicle.
