A new study by researchers in Japan has found a stronger correlation between nose length and penis size than with hand or foot size.

Researchers at Kyoto Prefectural University of Medicine analysed autopsy data from 124 men, measuring various body parts and comparing them to each man’s “stretched penile length” – the length of the penis when gently pulled while flaccid.
Their findings, published in the journal Basic and Clinical Andrology, suggest that nose size may indeed be a more reliable physical indicator.
Men with larger noses had an average penile length of about 5.3 inches (13.5cm), while those with smaller noses averaged about 4.1 inches (10.4cm).
The team said this difference was unrelated to height, weight or age, implying that the relationship may be determined by developmental factors established before birth.
“The link between nose size and penile length suggests that male hormone exposure during fetal development may influence both traits,” said the study’s lead author, Dr Hiroshi Ikegaya. “The prenatal environment may play a greater role than post-pubertal growth”.

Rena Malik, a urologist based in Beverly Hills, also cited the study, saying that traditional beliefs linking penis size to hand or foot size lack strong scientific evidence.
