What was done
Multivariate analysis evaluating the relationships between stretched penile length (SPL) and other anthropometric and genital measurements—specifically flaccid penile length, nose size, height, and body weight—in 126 adult males in their 30s to 50s.
What was found
The factor most strongly correlated with SPL was flaccid penile length (r = 0.565, P < 0.0001), followed closely by nose size (r = 0.564, P < 0.0001). Penile stretched rate correlated inversely with flaccid penile length (r = -0.690, P < 0.0001), but showed no significant correlation with SPL or penile circumference.
Why it matters
The observed correlation between nose size and stretched penile length suggests that penile dimension may be linked to developmental factors established prior to birth rather than being driven primarily by adult age, height, or weight.
Limits
The study is observational and cross-sectional, precluding causal conclusions. The sample is relatively small (n = 126) and restricted to males aged 30–50. Specific demographic background, measurement protocols, and biological mechanisms underlying the correlation are not detailed in the abstract.
