Abstract

PURPOSE: There have been a few reports investigating the measurement of penile lengths, but none that compare the results of circumcision with penile length. The aim of this study was to determine the correlation between penile length and circumcision, and the mean penile length of physically and sexually active young men in Korea.
MATERIALS AND METHODS
The penile lengths in the flaccid and stretched states were measured, between November 2002 and April 2003, in a random group of 2,335 young men without endocrine disorders or an anomaly of the penis. Patients were classified as circumcised (group 1, n=1,767) or uncircumcised (group 2, n=568). The age, body height, body weight, and flaccid and stretched penile lengths were analyzed.
RESULTS
The mean values of the flaccid and stretched penile lengths were 7.92+/-3.00 and 12.03+/-2.66cm, and 8.07+/-1.19 and 11.71+/-1.81cm in groups 1 and 2, respectively, with statistical significance according to the stretched length between the two groups (p<0.05). The flaccid and stretched lengths were correlated with height and weight in group 1 (p<0.05).
CONCLUSIONS
In this study, we confirmed the normal range for penile length of young adults in Korea. The results of this study showed that a circumcision did not influence the penile length or increase the penile length postoperatively.
