So if your index finger is 2.9 inches long and your ring finger is 3.1 inches long, you have a 2D:4D ratio of .935 (2.9/3.1 = .935). A longer ring finger compared to your index finger is considered a “low 2D:4D ratio.” If your index finger is 3.1 inches long and your ring finger is 2.9 inches long, your 2D:4D ratio would be 1.06 (3.1/2.9 = 1.06). A longer index finger compared to your ring finger is considered a “high 2D:4D ratio.”

Women whose left index and ring fingers are different lengths are more likely to be lesbians, a study suggests. This may be the result of exposure to more testosterone in the womb, the

Guys with long index fingers? Eh, not so much. It sounds bizarre, but it goes back to what we told you before: The longer your ring finger, the more testosterone you received in the womb. A study led by scientist Camille Ferdenzi of the University of Geneva confirmed that above all other factors Women whose left index and ring fingers are different lengths are more likely to be lesbians, a study suggests. This may be the result of exposure to more testosterone in the womb, the It is thought exposure to high levels of testosterone in the womb has a long-lasting effect on finger length. Those with a longer ring finger are likely to have been exposed to more testosterone. Well, it all has to do with testosterone. Scientists have known for a while that index fingers that are longer than ring fingers are a result of higher exposure to testosterone in the womb. While a long index finger is considered a more feminine hand — men who have them are more likely to be homosexual — a short index finger relative to the ring finger is a more masculine hand.

25 Jul 2016 Scientists have long noticed that men's ring fingers are generally longer than their index fingers. With women, it tends to be the reverse: their 

The ratio between them is known as the 2D:4D ratio. For instance, if your index finger is 2.9 inches long and your ring finger is 3.1 inches long, you have a ratio of 0.935. Oddly enough, the ring finger seems to have a higher number of receptors for testosterone and during early fetal development, So if your index finger is 2.9 inches long and your ring finger is 3.1 inches long, you have a 2D:4D ratio of .935 (2.9/3.1 = .935). A longer ring finger compared to your index finger is considered a “low 2D:4D ratio.” If your index finger is 3.1 inches long and your ring finger is 2.9 inches long, your 2D:4D ratio would be 1.06 (3.1/2.9 = 1.06). A longer index finger compared to your ring finger is considered a “high 2D:4D ratio.” A longer ring finger and shorter index finger typically indicates a low 2D:4D ratio and greater in utero exposure to testosterone. The ratio of two digits in particular, the palmar 2nd (index finger) and 4th (ring finger), is affected by exposure to androgens, e.g., testosterone while in the uterus and that this 2D:4D ratio can be considered a crude measure for prenatal androgen exposure, with lower 2D:4D ratios pointing to higher prenatal androgen exposure. But Galaburda thinks fetal testosterone plays a role too by reducing plasticity in the young brain, making males, susceptible to brain malformations that females manage to overcome. Intriguingly, when female rats are given extra testosterone, they too show signs of dyslexia. Ratios of 2nd digit (index finger) to 4th digit (ring finger). But there could be other secrets hiding in your hands: See, researchers have long known that relatively high levels of exposure to testosterone (the male sex hormone) in the womb can slow the growth of your index fingers, leaving you with a greater difference in length between your index and ring fingers (i.e. digit ratio).
