What was done
Two urologists measured the stretched penile length of 104 men in a prospective study to determine whether penile dimensions correlate with shoe size.
What was found
The median stretched penile length in the cohort was 13 cm, and the median UK shoe size was 9 (European 43). The authors found no statistically significant correlation between shoe size and stretched penile length (exact correlation coefficients and p-values were not reported in the abstract).
Why it matters
This study provides empirical anatomical measurements refuting the popular belief that a man's shoe size reliably reflects penile length.
Limits
The sample size is relatively small (104 men). The abstract does not provide exact correlation coefficients, p-values, or demographic details of the participants, and stretched flaccid length was used rather than erect length.
