Abstract
Objectives : To determine the penile size in adult Egyptians and to clarify the relationship between fully stretched penile measurements in normal subjects and erectile dysfunction patients.
Methods : This study included 1027 adult Egyptians presenting to
Kasr El-Aini outpatient clinic. Two groups of patients were included in this
research work. Group one,normal adults(949)and Group two, erectile
dysfunction patients(78). There were no differentiation of race,age, height
and weight. Penile length and girth were measured using a ruler and a tapemeasure respectively in the fully stretched states in both groups. All penile measurements were performed by the same physician.
Results : In group one : The mean of fully stretched length was 12.9 ±
1.9 cm and the mean of fully stretched girth was 8.9 ± 0.9 cm.
In group two : The mean of 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 statistically
significant difference (P<0.001) between them, while comparing the mean
of fully stretched penile girths in both groups revealed statistically nonsignificant difference (P=0.474) between them. There was 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 Egyptians is 12.9 cm, while the patients with erectile dysfunction
tend to have significantly shorter penises (11.2 1.5 cm).
