Gay men fingers
The length of your finger could provide clues to your sexuality, according to a study published in the journal Archives of Sexual Behavior.
In women, the index (second) finger and ring (fourth) fingers are typically of similar length, while in men there is usually a greater difference between the two (shorter index fingers and longer ring fingers).
Previous studies have suggested that there may be a link between prenatal hormone levels and differences in finger length, with those exposed to higher levels of the hormone testosterone more likely to have "male-typical hands". In the womb, both males and females are exposed to testosterone.
For their research, a team from the University of Essex in the U.K. examined sets of exact twins (14 male and 18 female) with alternative sexual orientations.
"We are interested in investigating the factors that contribute to such a fundamental difference between these genetically identical individuals," Tuesday Watts, lead creator of the study from Essex's Department of Psychology, told Newsweek. "The motivation for this study was to investigate whether differences in the level of exposure to testosterone during early development, was l

Previous research has uncovered a potential link between pre-natal hormone levels and differences in finger length, with those exposed to higher levels of ‘male’ hormone more likely to have ‘male-typical’ hands. Both men and women are exposed to the ‘male’ hormone testosterone in the womb.
Now an Essex examine of identical twins with different sexualities has discovered that not only is their sexuality different – their hands are too.
The study looked at 18 sets of female twins and found on average the lesbian twin had more ‘male-typical’ hands than her straight sister. Researchers also looked at 14 sets of male twins and found the gay twin had slightly more ‘male-typical’ hands than their straight brother – but the difference between the two was not viewed as significant.
Dr Tuesday Watts, who worked on the study with Dr Gerulf Rieger, both from the Department of Psychology, said: “Because exact twins, who share 100% of their genes, can differ in their sexual orientations, factors other than genetics must account for
Study links sexuality to length of fingers

BERKELEY, Calif.—Gay students have expressed skepticism about a University of California-Berkeley study that claims sexual orientation can be revealed through finger length.
Led by psychology professor Marc Breedlove and undergraduates Terrance Williams and Michelle Pepitone, the study start that the hands of lesbian women closely resemble those of men.
The study indicates that on women the index finger tends to be same in length to the ring finger, but on men and lesbians the index finger is slightly shorter.
Differences in finger lengths are evident in young children, researchers initiate , implying that lengths are determined by hormones in the womb.
“Our results suggest that events before birth (or even before conception in the case of older brothers) effect human sexual orientation,” the study states.
The researchers, however, found no difference between t
The author, science writer Mitch Leslie, gives us the rather startling number that over the past 20 years, more than 1400 papers have been published linking finger lengths to personality, sexual orientation, cardiovascular disease, cancer, and more.
What is this magical finger length ratio? Simple: it's the ratio between the lengths of your index (2nd) and ring (4th) fingers, also called the 2D:4D ratio. Take a look: is your index finger longer than your ring finger?
It turns out that most people contain slightlylonger ring fingers than index fingers, and in men the difference is a bit larger. If the ringer finger is longer, than the 2D:4D ratio is less than one. One recent research reported that this ratio was 0.947 in men and 0.965 in women. Another study found average beliefs of 0.984 and 0.994 for men and women. Not only is this a tiny difference, but in every study, the 2D:4D ratio among men and women overlapped, meaning the number alone doesn't reveal you very much.
Nonetheless, some researchers have taken this tiny physiolo
