According to the findings, a woman whose index finger is longer than her ring finger is likely to have a symmetrical and more appealing face.
For men, it is the opposite - those whose ring fingers are longer than their index fingers are more likely to be attractive to women. The initial statement is that that the length of the finger depends on the amount of testosterone that has been slammed onto them while still in their mothers' wombs.
However, the study showed that female felt attracted to these men's facial features and not voice or smell, meaning that it is more likely that the testosterone that is currently in the male's body and not the one that he's been stuffed with in a prenatal state is the actual women-attractor.
The discovery was made by Bernhard Fink of the University of Vienna, who measured the fingers of 100 men and women and photographed their faces using a digital camera. He used a computer programme to assess the symmetry of each face.
In another research by experimental psychologists from Oxford University and Northumbria University.
People whose ring fingers and index fingers were the same length were more likely to be faithful lovers, the research found.
In contrast, those with a longer ring finger, pictured, could be more likely to cheat.
They studied 600 men and women in Britain and the US. The study was specifically looking at the link between hand shape and sexual habits.
