How FINGER LENGTH could reveal your sexuality: Study finds women with more ‘male’ hands – where the ring and index digits are of different sizes – ‘are more likely to be lesbian’

The length of a person’s fingers could provide a clue to their sexuality, with women whose ring fingers are longer than their index digits more likely to be lesbian, a study has suggested.

Researchers at Essex University looked at sets of identical twins where one of the siblings was heterosexual.

They found that the homosexual twin tended to have a greater difference between the length of their index and ring finger, with the difference most pronounced among women.

Previous research has indicated that exposure to the male hormone testosterone in the womb could be linked to differences in finger length and also to sexuality.

Women’s index and ring fingers are typically of similar length while in men there is a greater difference.

Both men and women are exposed to the ‘male’ hormone testosterone in the womb.

The study observed that in 18 sets of female twins, the lesbian twin had more ‘male-typical’ hands than her straight sister.

In 14 sets of male twins the gay twin had slightly more ‘male-typical’ hands than their straight brother but the difference between the two was not viewed as significant.

A chart indicated that the index finger of non-straight women was typically around 90 to 100 per cent as long as the ring finger.
