Table 2 Comparison of the intracavernosal pressure changes induced by electrical stimulation of the cavernous nerves in rats 2 months postoperatively

From: Effects of unilateral/bilateral amputation of the ischiocavernosus muscle in male rats on erectile function and conception

Group Control group (n = 9) Sham operation group (n = 9) Uni-ICM amputation group (n = 10) Bi-ICM amputation group (n = 8) F 1P value
Baseline ICP (M±SD, mmHg) 16.82±3.07 18.44±2.80 15.72±4.27 17.98±2.93 1.233 0.314
Max ICP (M±SD, mmHg) 90.91±8.04 91.40±10.33 89.06±9.87 59.12±5.88* 26.22 <0.001
t -25.83 -20.46 -21.57 -17.71   
2P value <0.001 <0.001 <0.001 <0.001   
  1. Uni-ICM unilateral ischiocavernosus muscle, Bi-ICM bilateral ischiocavernosus muscle, ICP intracavernosal pressure, M±SD mean±standard deviation
  2. 1P values were calculated using one-way analysis of variance; the Bonferroni t test was used for multiple comparisons
  3. 2P values were calculated using covariance analysis of the max ICP, adjusted for the baseline ICP
  4. * indicates that the Max ICP of the Bi-ICM amputation group was lower than those of the control group, sham operation group, and Uni-ICM amputation group, but the difference was statistically insignificant (all P<0.05)
  5. Significant at P<0.05
