Correlation between NPT and AVSS (placebo and sildenafil citrate) was analyzed with cross table analysis.
Table 1 shows mean base rigidity percentage of these two groups in NPT, AVSS with placebo, and AVSS with sildenafil tests.
We also distinguished two groups of the patients according to AVSS results.
Three methods can be used for the assessment of erectile capacity: measurement of spontaneous erections during night sleep, the erectile response to AVSS in laboratory, and measurement of the response to intracavernosal smooth muscle relaxants such as prostaglandin El .
