title: Association between International Index of Erectile Function and axial penile rigidity in patients with erectile dysfunction.
abstract: 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 age+/-s.d. was 52.4+/-9.9 y. 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 (P<0.05 for each); (3) a significant association between overall presence of ED and low APR (P<0.05). IIEF score is associated with APR and can differentiate between patients with and without ED.
