To do so, they examined 14 sets of male identical twins and 18 sets of female identical twins with different sexual orientations. They then observed the variations of their hands, particularly measuring the length of the ring and index fingers. After analyzing the results, they found that bisexual and lesbian sisters had different size ring and index fingers, which they said was usually a male trait. On the other hand, the heterosexual sisters had similar size ring and index fingers.

The Science of Gay
Finger length may be an indication of sexual orientation, a controversial study has shown. Scientists from California found that lesbian women have a greater difference in length between their ring finger and index finger than straight women do. The same pattern was also found for homosexual men - but only when the researchers looked at those males that had several older brothers. The scientists from the University of California at Berkeley were testing a theory that higher levels of androgen - male sex hormones - in the womb influence both finger length and sexual orientation.

The length of a child's fingers can point to whether he or she is likely to be gay in later life, according to a study linking finger patterns to sexual orientation. Scientists believe the findings reveal a link between levels of exposure to sex hormones during foetal development and established differences in finger lengths between men and women. In women, the index finger - or forefinger - is typically almost the same length as the ring finger, or fourth digit.
Several studies have shown that there is a correlation between the digit ratio and hormones that people are exposed to in the womb, and hormones in the womb are one of the many avenues researchers are pursuing to find out why some people are gay, others are bi, and others are straight. So a study that compares sexual orientation and digit ratio would provide useful data in that context. First, most people — male or female, gay or straight — have a longer ring finger than index finger.
