Finger Size Determinants of Male Attraction

The ratio of the size of this man's finger is known related to sexuality and fertility.

The length of the index finger (index finger/2D) compared with the fourth finger (ring finger/4D) known by the ratio of 2D: 4D. Comparisons were considered proportional to show a man's attractiveness. The ratio of the size of this man's finger is known related to sexuality, fertility, and the level of competition.

A low ratio, with a longer ring finger than index finger, indicating a high level of testosterone. Not only that, the ratio was also depict a man look more attractive and has a symmetrical figure.

This effect is more noticeable on the finger of right hand than the finger of his left hand. That's according to research conducted by Dr. Camille Ferdenzi and his team from the University of Geneva, Switzerland.

They measured the ratio of digits 2D: 4D in 49 men. Then show pictures of the man on the women included in the study. The women were asked to assess the attractiveness of short-term, such as the desire to have dinner with him. Including long-term appeal, such as a future partner. Figure symmetrical and masculinity is also taken into account.

Researchers found that the second appeal, the long and short-term, highly correlated with the ratio of 2D: 4D. The lower the ratio, the higher the attractiveness scores given by the women. Symmetrical figure is also known to have strong ties, but the masculinity factor was not found.

"This illustrates the preference of women to men with a ratio of 2D: 4D. It may also be driven by the fact that these people have more symmetrical faces," said Dr. Ferdenzi, as quoted by the Telegraph.co.uk.

Testosterone level indicators such as scent and sound pressure did not have a relationship with the ratio of 2D: 4D. According to the researchers, this may be because these developments happen in the future so that is not affected exposure to hormones in the womb.
