Abstract

PURPOSE
To evaluate the clinical correlation between penile size and prostatic volume.
MATERIALS AND METHODS
A total of 196 men were included in this study, 96 patients diagnosed as benign prostataic hyperpalsia(BPH, mean age: 67.2+/-18.8) by transurethral ultrasonography(TRUS), and 100 healthy volunteers(mean age: 48+/-16.2). The stretched penile length and penile circumference were measured by one examiner. We compared penile size with prostatic volume. BPH patients were classified as group I(30~39 ml), group II(40~49 ml) and group III(above 50 ml) by prostatic volume.
RESULTS
For penile length and penile circumference, the mean values were 12.3+/-2.0 cm and 9.1+/-1.1 cm in group I, 12.6+/-2.2 cm and 9.2+/-1.0 cm in group II, 13.9+/-2.7 cm and 9.8+/-1.2 cm in group III, and 12.3+/-1.3 cm and 9.0+/-1.2 cm in control group, respectively. Compared to the control group, penile size was significantly higher in group III(p <0.05).
CONCLUSIONS
Larger prostatic volume, especially above 50 ml, is associated with a significant increase in penile size.
