Study links men's finger length to other factors
A Korean study has shown that there is a relationship between the length of the ring finger compared to the index finger (the 2D:4D ratio) and the size of the male genitalia. It is believed that testosterone levels in the fetus influence the development of these fingers, and the longer the ring finger relative to the index finger, the larger the genitalia. The study, conducted on 144 men in Korea, revealed that the finger length ratio provides a more accurate estimate of penis size than overall height, and its analysis links hormones to the development of male characteristics. The findings contribute to a deeper understanding of the biological factors that influence masculine traits in men.
