Researchers from the University of Essex reported that women are given their sexual orientation – in particular, it is necessary to pay attention to the length of index and ring fingers.
“Women whose index and ring fingers on his left hand vary in length, often have a sexual orientation”, – quotes the experts of the BBC.
A similar pattern was discovered by experts after a survey of 18 pairs of female twins in which sisters had a different sexual orientation. Those of them who preferred non-traditional relationships, index finger on his left hand was obviously longer.
According to the researchers, human sexuality is determined in the womb and depends on the impact on the fetus of the male sex hormone in the womb. Elevated levels of testosterone influencing the future of daughters increases the likelihood that they will later gravitate towards bisexuality or homosexuality, said experts. Testosterone also determines the difference in the length of the fingers in women.
Interestingly, a study involving twins-men of different orientation showed no relationship between the difference in the length of the fingers and the features of sexual preference.
