Nose Size Predicts Adult Erectile Penile Length

Previous studies have proved that nose size has a positive correlation with stretched penile length but stretched penile length does not fully represent erectile penile length. It is considered that the formation and growing ability of the penis is determined by the action of androgen in the fetal period and nose size has also been determined to some extent before birth. If the nose size is indeed related to the length of the penis, there must be a common mechanism behind it. To further confirm the relationship between nose size and penile length, especially erectile penile length, a correlation analysis was carried out by collecting general data and the data related to the nose, ears, and genitals of 377 males aged 20–56 years, including erectile penile length and erectile penile circumference. The results revealed that nose size had the highest correlation with erectile penile length (r = 0.507, p = 0) and flaccid penile length (r = 0.451, p = 0). Therefore, it is believed that nose size is an independent predictor of flaccid and erectile penile length, and the common factors that contribute to this correlation may appear in the fetal period.
