What Your Finger Length Can Reveal About Your Sexuality

Let's be honest, this is some pretty handy information to know.

A new study has found that women are more likely to be lesbians if their left index and ring fingers are different lengths.

Before you scoff, yes, this is a legitimate study and not just some random palm reader’s musings.  The University of Essex carried out the research and found that the discrepancy may be down to the exposure of testosterone in the womb.

To get to this conclusion, they measured the fingers of 18 pairs of identical female twins – where one was straight and the other was gay.

They found that on average, the lesbians, but not the straight twins, had different sized index fingers – a trait which is typically seen on men.

The researchers carried out the same study on 14 identical male twins but didn’t find any link.

The author of the study, Dr Tuesday Watts, said that “because identical twins, who share 100% of their genes, can differ in their sexual orientations, factors other than genetics must account for the differences.”

She continued: "Research suggests that our sexuality is determined in the womb and is dependent on the amount of male hormone we are exposed to or the way our individual bodies react to that hormone, with those exposed to higher levels of testosterone being more likely to be bisexual or homosexual.

"Because of the link between hormone levels and difference in finger lengths, looking at someone's hands could provide a clue to their sexuality."

It's not the first time scientists have noticed a discrepancy between our  index and ring fingers.

An study from the 1980s first speculated that the size difference may have something to do with our hormone levels -- as men usually had longer ring fingers than woman.

Then, in 1998, a paper was published by psychologist John Manning, which cemented the theory that the 2D (second digit) and 4D (fourth digit) ratios were determined by the sex hormone testosterone.

It then took another 13 years before scientists could really confirm the theory thanks to prenatal testing.

Science, man.
