text_B: The digit ratio is the ratio of the lengths of different digits or fingers typically measured from the midpoint of bottom crease -LRB- where the finger joins the hand -RRB- to the tip of the finger .. digit. finger. It has been suggested by some scientists that the ratio of two digits in particular , the 2nd -LRB- index finger -RRB- and 4th -LRB- ring finger -RRB- , is affected by exposure to androgens , e.g. , testosterone while in the uterus and that this 2D  :4 D ratio can be considered a crude measure for prenatal androgen exposure , with lower 2D  :4 D ratios pointing to higher prenatal androgen exposure .. index finger. index finger. ring finger. ring finger. androgen. androgen. testosterone. testosterone. uterus. uterus. The 2D  :4 D ratio is calculated by dividing the length of the index finger of a given hand by the length of the ring finger of the same hand .. index finger. index finger. ring finger. ring finger. A longer index finger will result in a ratio higher than 1 , while a longer ring finger will result in a ratio lower than 1 .. index finger. index finger. ring finger. ring finger. The 2D  :4 D digit ratio is sexually dimorphic  : although the second digit is typically shorter in both females and males , the difference between the lengths of the two digits is greater in males than in females .. digit. finger. sexually dimorphic. sexually dimorphic. A number of studies have shown a correlation between the 2D  :4 D digit ratio and various physical and behavioral traits .. digit. finger
