Table 1 Comparison of the intracavernosal pressure changes induced by electrical stimulation of the cavernous nerves in rats measured immediately after surgery

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

Group Control group
(n = 10)
Sham operation group (n = 10) Uni-ICM amputation group (n = 10) Bi-ICM amputation group (n = 10) F 1P value
Baseline ICP (M±SD, mmHg) 17.44±2.50 17.81±2.81 16.73±2.11 14.78±2.78 2.833 0.052
Max ICP (M±SD, mmHg) 93.51±10.78 95.07±10.40 83.49±12.38 33.57±6.72* 79.691 <0.001
t -21.74 -22.67 -16.81 -8.17   
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 max ICP, adjusted for the baseline ICP
  4. * indicates that the max ICP of the Bi-ICM amputation group was significantly lower than those of the control group, sham operation group, and Uni-ICM amputation group (all P<0.05)
  5. Significant at P<0.05
