title: [Methods for evaluation of penile erection hardness].
abstract: Penile erection hardness is one of the key factors for successful sexual intercourse, as well as an important index in the diagnosis and treatment of erectile dysfunction (ED). This article gives an overview on the component and impact factors of erection hardness, summarizes some commonly used evaluation methods, including those for objective indexes, such as Rigiscan, axial buckling test and color Doppler ultrasonography, and those for subjective indexes of ED patients, such as IIEF, the Erectile Function Domain of IIEF (IIEF-EF), and Erection Hardness Score (EHS), and discusses the characteristics of these methods.
