“…The response to erotic stimuli is susceptible to several factors. Repetitive viewing of the same erotic video, habituation to erotic movies, lack of interest in erotic movies, deterioration in general health, age, and psychological factors (severe psychotic disorder or anxiety associated with unfamiliar surroundings, the examination itself, and the recording device) may result in false-negative responses [17]. In our study, 9 patients (29%) with normal NPT patterns did not have a normal response to AVSS, and the age of these patients was significantly higher than that of the patients with a normal response to AVSS and normal NPT patterns.…”

Introduction: Although the nocturnal penile tumescence (NPT) test is considered the gold standard for the differential diagnosis of psychogenic versus organic erectile dysfunction (ED), concerns have recently been raised regarding the financial and time expenditure it demands. We evaluated the diagnostic efficacy of the audiovisual sexual stimulation (AVSS) test as an alternative to the NPT test. Patients and Methods: A total of 43 patients with ED were examined. Each patient filled in an International Index of Erectile Function (IIEF) questionnaire. The evaluation of each patient consisted of AVSS and NPT tests which were performed using the RigiScan Plus. The results obtained with the two tests were compared. The patients with normal NPT patterns were presumed to have a psychogenic etiology of their ED and those with abnormal NPT patterns to have an organic etiology. Results: The overall IIEF score was 32.5 ± (SD) 9.2, and the erectile domain score was 12.2 ± 4.5. Twenty-three patients had normal responses to the AVSS test, while 20 had abnormal responses. Twenty-two of the former 23 patients and 9 of the latter 20 patients had normal NPT patterns. Therefore, the AVSS test discriminated psychogenic ED with 71% sensitivity and 92% specificity. The overall accuracy of the test in this study was 77%. Conclusions: The AVSS test is simple, practical, and inexpensive, and its diagnostic accuracy is comparable to that of the NPT test. We conclude that the AVSS test should be the examination of choice for the primary etiological diagnosis in ED.

“…Results may not be readily comparable across different studies because of the differences in the test environment, the test protocol, the patient population, the length of observation and the nature of sexual stimulation [17]. However, in a similar study, the effects of single oral doses of 10, 25 and 50 mg sildenafil were investigated in 12 patients with ED.…”

“…The length of the test period was another factor which made this technique negligible for the clinician. However, VSTR is preferred to NPTR with regard to its reliable results, shorter test period, enabling the physician to compare objective data with the patient's satisfaction on erection and unnecessary need for regular sexual partners [27][28][29][30]. In the VSTR test, 70% of rigidity and a 10- 25 min period of erection were accepted as normal in accordance with the NPTR test [32,34].…”

“…However, difficulties with respect to application, inadequate simulation compared with real erection, incomplete elimination of organic causes and timeconsuming test period are the main problems encountered in the clinical practice [1,11,26]. Today, some data in the literature concerning the comparative results of the NPTR test and visual stimulation tumescence and rigidity (VSTR) test were not able to demonstrate a meaningful difference with respect to diagnostic value of the two tests [16,[27][28][29][30]. Onset of the erectile function with sildenafil citrate test needs sexual stimulation which also makes the VSTR test better than NPTR.…”

Aim: An objective evaluation of the psychogenic cause of erectile dysfunction by performing the visual stimulation tumescence and rigidity (VSTR) test and sildenafil citrate test, together with the effectiveness of sildenafil citrate medication on impotence caused by different etiologies. Material and Methods: Between 1998 and 2000, a total of 36 men (12 patients with diabetic etiology, 5 patients with vasculogenic risk factor) were enrolled in this study. The mean age of patients was 53 (27–67) years. Following standard questionnaires, including a detailed anamnesis from an andrologic viewpoint, VST was performed in an ambulatory setting and beginning with a test dose of 50 mg. At the end of 2 h, the data was evaluated with computer assistance (Rigiscan device) and if a satisfactory erection had not occurred, an additional second dose of sildenafil citrate (50 mg) was given until there was a satisfactory erection. Results obtained from VST: results were classified as group I (fully rigidity, >10 min erection, >70% of rigidity, possible vaginal penetration), group II (unstable erection, 5 min erection, >70% of rigidity, possible vaginal penetration) and group III (tumescence without rigidity, <5 min erection, <70% of rigidity, impossible vaginal penetration). The results obtained during the first 1 h of the VSTR test were regarded as the patient’s own erectile condition and later data was accepted as the real effect of sildenafil citrate. The Fisher exact test was used for statistical evaluation including pre- and post-sildenafil effect on erectile rigidity and duration of erection. Results: The erection status of patients was sufficient in 17 (47.2%) in group I, it was insufficient but sufficient enough with an increased dose of sildenafil citrate in 10 (27.7%) in group II, and insufficient without/with full dose of sildenafil citrate in 9 (25%) in group III. Considering rigidity and total erectile period, there was a statistical significant difference between the first two groups with respect to the early and late sildenafil citrate effects on the VSTR test (p < 0.05). Again, 10 patients with known risk factors (diabetes mellitus 5 and vasculogenic 5) in the second group seemed to give a good response to repeated dosage of sildenafil citrate which has been found to be very interesting. However, the rest of the diabetic patients (n = 7) in the third group showed no erection despite the increasing and repeated doses of sildenafil citrate. Conclusion: Sildenafil citrate with the VSTR test has effective and reliable results which was regarded as very important to diagnose and determine objectively the amount of therapeutic doses in impotence. In accordance with the literature data, our results also confirm the reliability and the practical nature of the VSTR test, which is less time-consuming and cheaper than the nocturnal penile tumescence and rigidity (NPTR) test. In the VSTR test, necessary doses of medication needed for satisfactory erection were easily regulated in patients with certain kinds of impotence. Add...
