Study explores potential links between facial and bodily measurements and genital size
Researchers from Ulsan University Hospital in South Korea investigated whether measurable traits in men might relate to genital dimensions. The team reported that, in their sample, a larger nose was associated with a longer penis, while greater foot length appeared linked to increased penile girth. The study was published in Translational Andrology and Urology.
In this work, data from 1,160 men in their 30s were analyzed. Measurements included the nose, feet, and penis when not erect. The researchers observed that nose size correlated with penis length, and that longer feet tended to correspond with a larger circumference of the penis.
The scientists noted that several earlier investigations have suggested a possible explanation: higher levels of testosterone exposure in the womb may influence the development of both facial features and male genitalia. Testosterone is known to play a key role in the formation of the nose and genitals during male fetal development.
Importantly, the authors stressed that their findings are not definitive, largely due to the relatively small participant pool. They called for additional research with larger and more diverse groups to determine whether these associations hold across broader populations.
The report also touched on historical observations related to sexual arousal, noting that certain reproductive responses can be linked to sensations of pain when orgasm is delayed or inhibited, a point discussed within ancient medical and philosophical writings.
