Studies indicate that finger length ratios but not the size of the fingers themselves can provide some clue about member length. Nobody has ever hit my hands. I have never heard of this. Look at those hands.
Penis Size: It May Be Written in the Length of His Fingers
Can hand size help predict erect penis size? – The Daily Evergreen
The second to fourth digit ratio 2D:4D has been proposed as a putative biomarker for prenatal testosterone and covaries with the sensitivity of the androgen receptor AR. Both prenatal testosterone and the AR play a central role in penile growth. In this study, we investigated the relationship between digit ratio and penile length. Korean men who were hospitalized for urological surgery at a single tertiary academic centre were examined in this study, and men aged 20 years or older who gave informed consent were prospectively enrolled. Right-hand second- and fourth-digit lengths were measured by a single investigator prior to measurement of penile length. Under anaesthesia, flaccid and stretched penile lengths were measured by another investigator who did not measure nor have any the information regarding the digit lengths.
Penis Size Linked to Finger Length
A small difference between ring and index fingers could indicate a larger erect penis. A larger difference could imply a smaller penis. There have been several studies that have found that finger ratio does correspond with penis length. A smaller difference in length between these two fingers means a higher likelihood of a larger penis. The first of such study was a Korean study in
The lower the ratio, the longer the penis. The new study was conducted on Korean men who were hospitalized for urological surgery. They data suggested that those with a lower ratio, whose index finger or second finger, 2D was shorter than the ring finger or fourth finger, 4D , had a longer stretched penis length, which is well correlated with erect size. Previous studies have linked the so-called 2D:4D ratio of finger length with exposure to the sex hormones estrogen and testosterone in the womb. Higher testosterone levels during fetal development are associated with a lower 2D:4D ratio, while higher estrogen levels are connected with a higher one.
