Penis Length Data

The graph above is based on the following data. All measurements are made NBP, along the top of the shaft. To measure NBP place a ruler or tape at the bottom of the shaft without pressing in towards the pubic bone. Kinsey measured uncircumcised men with the foreskin fully retracted.
