PURPOSE: Is there any relationship between penile size and physical stature? This study was performed to answer this question and provide guidelines of penile size to assist in counseling patients for penile augmentation. MATERIALS AND METHOD: Penile size, body weight and height were measured in 150 young healthy men, and the body mass index(BMI) was calculated in weight(kg)/height(m)2. The penile length and circumference were measured with tape in flaccid and erect states. The 'lengthening ratio' was calculated by 'erect length/flaccid length', and 'tumescent ratio' was calculated by 'erect circumference/flaccid circumference'. All the data was statistically evaluated and the following results were obtained. Result : The average length and circumference were 8.26+/-1.07cm and 8.34+/-1.03cm respectively in the flaccid state, and 13.42+/-1.38cm and 11.17+/-1.05cm in the erect state. The average lengthening and tumescent ratios were 1.64+/-0.22 and 1.35+/-0.08, and were negatively correlated to the flaccid penile length and circumference. Height was positively correlated to erect penile length and lengthening ratio. There was a relationship between body weight and erect penile length in a positive direction, but with other penile parameters there were none. There was no relationship between BMI and any parameters of penile size. However, the erect penile length of the normal BMI group was longer than that of the lower BMI group.
The results show that the flaccid penile size is related to the erect penile size and there is some relation between penile size and physical stature. We believe these results will be applicable to the penile augmentation.
