Penile length and circumference among normal adult Egyptian men

Abstract

Accurate measurement of penile length is important for both clinical and academic purposes. For this reason, a standard practice for measurement has been defined to maintain consistency. Rather than measuring a flaccid penis, which offers limited clinical significance, stretched penile length (SPL) measurement is considered best practice for adult men as it most closely replicates normal erect penile length. In this study, we aimed to assess the stretched penile length and penile circumference in a sample of physically normal Egyptian men and to determine the penile anthropometry-somatometric parameters relationship. The current study demonstrated that the mean stretched penile length of this sample of Egyptian men was 13.0 ±1.9 cm and the flaccid penile circumference was 9.3±1.1; which are consistent with the results of previous studies done in Egypt and with studies done within the same geographical region. There were significant positive correlations between penile measures and height, weight, and BMI with no significant correlations between penile measures and age. Our study results revealed as well that there was no significant difference between age grades regarding penis length and penis circumference. The previous correlations agree with most of the studies except for BMI which remains controversial whether it has positive or negative correlation with the penile anthropometry.
