The effects of torsion on testosterone, corticosteroid and luteinizing hormone (LH) levels. Torsion impaired testosterone secretion capacity of (A) Leydig cells and (B) testicular interstitial cells. (C) The testosterone levels of testicular interstitial fluid were enhanced in the ipsilateral testes, but suppressed in the contralateral testes after unilateral torsion. (D) Experimental torsion increased plasma corticosterone levels and reduced plasma LH levels, which contributed to the decline in plasma testosterone levels. Values are mean ± SEM. *p<0.05, vs. respectively contralateral testes; ⁺p<0.05, vs. sham (S) group; ^#p<0.05, vs. ipsilateral 1 h group; ^&p<0.05, vs. counterpart vehicle treatment.
