INTRODUCTION AND OBJECTIVES:
We are interested in the relation between penile length (PL) and prostate volume (PV) because we have been impressed that PL is relatively long among the patients with benign prostatic hyperplasia…..
From April 2010 to September 2011, consecutive 431 male patients who underwent transrectal ultrasound-guided prostate needle biopsy were recruited for this study…. PL was measured by a ruler along the dorsum of the penis from the pubopenile junction to the tip of the glans as described by Wessells et al (J Urol 156:995-997, 1996)….
The mean age of patients was 67.9 +/- 7.0 (range: 47-84) years. Mean PL in flaccid and stretched states was 94.1 +/- 15.4 mm and 122.2 +/- 17.2 mm, respectively….

Note: Age distribution of participants could cause depressed values, measured PL value is non-bone pressed stretched length (NBPSL) and study is much larger (n = 421) than Wessel (n = 80). It is however, similar to Wessel’s majority European sample study [90% European and African, 10% Asian, flaccid = 88.5 mm +/- 23.8, stretched = 124.5 +/- 27.1 mm, age: 54 +/- 14.37] as well as Chen et al. (2000) for European Jews in Israel: flaccid = 83 mm +/- 13 mm, stretched = 125 +/- 14 mm (mean: 47 yrs, n = 55). This study further invalidates the WorldPenisSize 109.2 mm value for Japan.
