INTRODUCTION: With the increase in penile augmentation procedures it becomes important to assess what is the normal erect penile size in both potent men and men with erectile dysfunction (ED). AIM: The aim of this work is to define the average stretched penile size in normal men and ED patients. MAIN OUTCOME MEASURES: Penile length and girth. METHODS: This study included 1,027 adult men presenting to a university hospital outpatient clinic. Two groups of patients were included in this research work. Group I comprises normal adult men (949) and Group II, ED patients (78). There were no differences of race, age, height, and weight. Penile length and girth were measured using a tape measure and rigid ruler in the fully stretched states in both groups. All penile measurements were performed by the same physician. RESULTS: In normal men (Group I) the mean of the fully stretched length was 12.9 +/- 1.9 cm and the mean of the fully stretched girth was 8.9 +/- 0.9 cm. In ED patients (Group II), the mean of the fully stretched length was 11.2 +/- 1.5 cm and the mean of fully stretched girth was 8.8 +/- 0.8 cm. Comparing the mean of fully stretched penile lengths in both groups revealed statistical significant difference (P < 0.001) between them, whereas comparing the mean of fully stretched penile girths in both groups revealed statistical nonsignificant difference (P = 0.474) between them. There were significant positive correlations between fully stretched penile lengths and fully stretched penile girths in both groups. CONCLUSION: The average of fully stretched penile length in normal potent men is 12.9 cm, whereas the patients with ED tend to have significantly shorter penises (11.2 +/- 1.5 cm).
