OBJECTIVE: To establish if the ‘myth’ about whether the size of a man’s penis can be estimated from his shoe size has any basis, in fact. SUBJECTS AND METHODS: Two urologists measured the stretched penile length of 104 men in a prospective study and related this to their shoe size. RESULTS: The median stretched penile length for the sampled population was 13 cm and the median UK shoe size was 9 (European 43). There was no statistically significant correlation between shoe size and stretched penile length. CONCLUSION: The supposed association of penile length and shoe size has no scientific basis.
Their methodology obviously … oh, never mind. It does not end here. The original cite has “Related Articles” that get even farther from reality.
I suppose we should be fortunate that they are not asking this question the other way ’round. For the benefit of shoe sales departments.
