Penile length not associated with shoe size

There is no scientific basis for the supposed association between shoe size and penile length. A study from London has laid to rest the common myth about shoe size once and for all.

The study recruited 104 men presenting at a urology department for various reasons. The authors measured stretched penile length, which apparently correlates well with erect length in other studies. The measurement was done by two urologists to reduce observer bias and recorded to the nearest 0.5cm. The age and shoe size of the patient were also recorded.

The mean patient age was 54 (range 17-84 years), with peaks in the fourth and eighth decades of life. The median stretched penile length was 13cm (6-18cm) and the median UK shoe size was nine (5.5 to 13). The linear regression between stretched penile length and shoe size suggested no statistically significant relationship.

I was slightly bemused by the number of studies in respected peer-reviewed journals about penis size. I now feel equipped with expert knowledge to reassure all the men who come to me wanting penis enhancements, and can quote the ‘average' size after reading papers that measured thousands of men from countries including India, Jordan, Brazil and Italy. There are also some interesting studies that have looked at the association between gluteal size and penile length in Nigerian men and other somatometric parameters among Greeks.
