OBJECTIVES: To systematically review and create nomograms on flaccid and erect penile size measurements.
METHODS: Study key eligibility criteria: measurement of penis size by a health professional using a standard procedure; a minimum of 50 participants per sample Exclusion criteria were samples with a congenital or acquired penile abnormality. previous surgery, complaint of small penis size or erectile dysfunction Synthesis methods: Calculation of a weighted mean and pooled standard deviation and simulation of 20,000 observations from the normal distribution to generate nomograms of penis size.
RESULTS: Nomograms for flaccid pendulous (n = 10,704, mean 9.16cm, sd 1.57) and stretched length (n=14,160, mean 13.24cm, sd 1.89), erect length (n = 692, mean 13.12cm, sd 1.66), flaccid circumference (n = 9,407, mean 9.31cm, sd 0.90); and erect circumference (n = 381, mean 11.66cm, sd 1.10) were constructed. Consistent and strongest significant correlation was between flaccid stretched or erect length and height, which ranged from r = 0.2 to 0.6.
CONCLUSIONS: Penis size nomograms may be useful in clinical and therapeutic settings to counsel men and for academic research.
LIMITATIONS: A relatively small number of erect measurements were conducted in a clinical setting and the greatest variability between studies was with flaccid stretched length.
