It’s been a controversy for years. And yet, it’s also the butt of jokes, something you do in high school with your friends. You hold up your hand, fingers together. And depending on the length of your ring finger as compared to your index finger, it tells you if you are gay or not. And in high school it is then put aside as a joke.
However, some scientists take it very seriously and there have been several studies that claim to actually show a correlation between the length of your fingers and your sexual orientation.
Scientists in Berkeley, California almost 10 years ago released a study that says lesbian women and gay men have a greater difference in length between their ring finger and index finger than straight women do.

According to a BBC article published at the time about the study, the scientists were testing a theory that higher levels of androgen – male sex hormones – in the womb influence both finger length and sexual orientation.
Normally, it was thought that the ring finger and index finger tend to be about the same length in women, while in men, the index finger is usually shorter. But, the study found that in lesbian women, they seemed to have a shorter index finger.
