Association between International Index of Erectile Function and axial penile rigidity in patients with erectile dysfunction

摘要

We investigated the association between the International Index of Erectile Function (IIEF) and axial penile rigidity parameters in patients with erectile dysfunction (ED). A total of 516 male patients (491 patients with ED and 25 patients without ED) were assessed using IIEF. Patients were assessed for axial penile rigidity (APR) using a digital inflection rigidometer. Mean ages.d. was 52.49.9y. ED was mild in 11.4% of the patients, moderate in 40.1%, and severe in 48.5%. Regarding APR, the following was found: (1) no significant difference between patients who had a mild degree of ED and patients who had no ED (P>0.05); (2) a significant difference between patients with different degrees of ED (PP<0.05). IIEF score is associated with APR and can differentiate between patients with and without ED.
