Comparison between three groups via nocturnal penile tumescence and rigidity
| Parameters | Healthy controls | Psychogenic ED | Organic ED | p-value |
|---|---|---|---|---|
| DOEE (min) | 91.13 (45.19) | 75.75 (73.31) | 17.25 (47.13) | p < .001 |
| DOTR60 (min) | 32.50 (19.06) | 34.25 (37.63) | 1.50 (7.00) | p < .001 |
| NONE | 1.00 (1.00) | 1.00 (1.00) | 0 | p < .001 |
| NOEE | 5.00 (3.00) | 4.00 (2.00)** | 1.00 (2.00) | p < .001 |
| AER of tip (%) | 49.00 (14.00) | 60.00 (35.25) | 11.00 (38.75) | p < .001 |
| AER of base (%) | 62.50 (28.50) | 72.50 (33.00) | 23.00 (55.00) | p < .001 |
| ∆Tumescence of tip (%) | 47.35 (20.79) | 32.79 (15.35)** | 16.67 (24.91) | p < .001 |
| ∆Tumescence of base (%) | 42.15 (22.23) | 33.98 (9.31)* | 25.00 (33.98) | p < .001 |
ED erectile dysfunction, DOEE duration of erectile episodes, DOTR60 duration of tip rigidity over 60%, NONE number of normal events, NOEE number of erectile episodes, AER average event rigidity
Data are shown as median (interquartile range). ∆Tumescence = (increased or maximum tumescence–minimum tumescence)/minimum tumescence
*p < .05 between Healthy controls and psychogenic ED, **p < .01 between Healthy controls and psychogenic ED
