The digit ratio is the ratio of the lengths of different digits or fingers typically measured from the midpoint of bottom crease where the finger joins the hand to the tip of the finger. There are also studies that suggest that the 2D:4D ratio is also influenced by prenatal estrogen exposure, and that it thus correlates negatively not with prenatal testosterone alone, but rather with the prenatal testosterone to estrogen ratio T:O. 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. The 2D:4D 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. A number of studies have shown a correlation between the 2D:4D digit ratio and various physical and behavioral traits.
By Telegraph Men. This time, researchers at McGill University in Canada suggest men with ring fingers longer than their index fingers are more likely to be kind and caring than those whose second digit is longer. A day study of men found that men with comparatively longer ring fingers were more likely to laugh, compromise, compliment others and smile. A longer ring finger indicates greater exposure to the male hormone. Why are so many middle-aged men committing suicide? Circumcised men may soon be able to regrow their foreskin. Men with longer ring fingers are more likely to be promiscuous, according to a joint study carried out by the Oxford University Department of Experimental Psychology and Northumbria University and published earlier this month.
BERKELEY -- The level of male hormones in the womb can influence an unborn child's future sexual orientation, according to new research from a University of California, Berkeley, professor who used an unusual technique - measuring finger length - to gather evidence. Marc Breedlove, professor of psychology, also found that higher levels of these male hormones, or androgens, can create a greater than normal tendency for both males and females to develop a homosexual orientation. Breedlove looked at relative finger length because it is influenced by androgen levels in the womb and thus is an approximate measure of fetal androgen levels.
If you need further proof that we, as humans, are travelling back in time to the s, look no further than this latest batch of research from Essex University. A study by Dr Tuesday Watts has discovered that the difference in length between your index and ring finger could indicate whether you are gay or not. The study was conducted by measuring the fingers of 18 pairs of identical female twins, where one was straight and the other identified as homosexual.
