Purpose:
We provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation.
Materials And Methods:
We prospectively measured flaccid and erect penile dimensions in 80 physically normal men before and after pharmacological erection.
Results:
Mean flaccid length was 8.8 cm., stretched length 12.4 cm. and erect length 12.9 cm. Neither patient age nor size of the flaccid penis accurately predicted erectile length. Stretched length most closely correlated with erect length.
Conclusions:
Only men with a flaccid length of less than 4 cm., or a stretched or erect length of less than 7.5 cm. should be considered candidates for penile lengthening.
