Penile length and circumference: are they related to nose size?

We investigated the relationship between the size of the penis and that of the nose.

We retrospectively analyzed 1,160 patients whose nose and penis sizes were measured. These participants were selected from a subset of 1,531 patients who visited the Dr. JOMULJU Urology Clinic between March and October 2022. Patients aged <20 years and those who underwent surgery for the nose and penis were excluded. Nose size was determined by measuring the length, width, and height of the nose, which were used to calculate the volume of the triangular pyramid. Stretched penile length (SPL) and penile circumference before erection were measured. The participants' height, weight, foot size, and serum testosterone levels were measured. Testicular size was measured using ultrasonography. Predictors of penile length and circumference were assessed using linear regression analysis.

The participants' average age was 35.5 years, mean SPL was 11.2 cm, and mean penile circumference was 6.8 cm. Univariate analysis revealed that body weight, body mass index (BMI), the serum testosterone level, and nose size were associated with SPL. Multivariable analysis revealed that BMI (P=0.001) and nose size (P=0.023) were significant predictors of SPL. Univariate analysis revealed that penile circumference was related to an individual's height, weight, BMI, nose size, and foot size. Multivariable analysis revealed that body weight (P=0.008) and testicular size (P=0.002) were significant predictors of penile circumference.

Nose size was a significant predictor of penile size. The sizes of the penis and nose increased with a decrease in BMI. This interesting study confirms the truth of an erstwhile myth about penis size.
