摘　　要：Background： Currently available evaluation criteria lbr penile tumescence and rigidity have been fraught with controversy. In tiffs study, we sought to establish normative Chinese evaluation criteria lbr penile tumescence and rigidity by utilizing audiovisual sexual stimulation and RigiScanTM test （AVSS-Rigiscan test） with the administration of phosphodiesterase-5 inhibitor. Methods： A total of 1169 patients （aged 18-67 years） complained of erectile dysfunction （ED） underwent AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor. A total of 1078 patients whose final etiological diagnosis was accurate by means of history, endocrine, vascular, and neurological diagnosis, International Index of Erectile Function 5 questionnaire, and erection hardness score were included in the research. Logistic regression model and receiver operating characteristic curve analysis were performed to determine the cutoffvalue of the RigiScanTM data. Then, the multivariable logistic analysis was used in the selected variables. Results： A normal restllt is defined as one erection with basal rigidity over 60% sustained for at least 8.75 rain, average event rigidity of tip at least 43.5% and base at least 50.5%, average maximum rigidity of tip at least 62.5% and base at least 67.5%, △tumescence （increase of tumescence or maxinaum-mininaum tumescence） of tip at least 1.75 cm and base at least 1.95 cm, total tumescence time at least 29.75 rain, and times of total tumescence at least once. Most importantly, basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5%, and base at least 50.5% would be the new normative Chinese evaluation criteria for penile tumescence and rigidity. By multivariable logistic regression analysis, six significant RigiScanTM parameters including times of total tumescence, duration of erectile episodes over 60%, average event rigidity of tip, Atumescence of tip, average event rigidity of base, and Atunaescence of base contributeBackground： Currently available evaluation criteria lbr penile tumescence and rigidity have been fraught with controversy.
