Studies indicate they are most common in men with longer than average ring fingers. Digits are subtly affected by testosterone and estrogen produced in the womb by the fetus not by the mother. In women, these fingers are usually the same length or the index digit is just a bit longer.

Because of the influx of sex hormones at this prenatal stage, men tend to have ring fingers that are slightly longer than their index fingers. They are not only claiming that the 2D:4D ratio is predictive of homosexuality, but also that exposure to prenatal androgen is the root cause of both finger lengths and sexual orientation.

Between weeks 8 and 14, tiny fetal testes, ovaries and adrenal glands secrete the baby's own supply of sex hormones. The length of one’s index and ring fingers could be linked to sexual. The same study, published in Early Human Development , found that boys with female-type finger lengths are on average more emotional than other boys.

He believes digit ratio is an important, if indirect, tool for studying the fetal brain and the womb, an environment that's off-limits to scientists except for analysis by amniocentesis. Girls with masculine-type finger ratios tend to have higher hyperactivity scores and more problems relating to their peers than do other girls.

Scientists measured the fingers of 18 pairs of female identical twins, where. The question isn’t if the lengths are different, but how different they are.
