Physiological research has focused on finger-length patterns, specifically the relative length of the index and ring fingers, as a potential indicator of sexual orientation. Studies have shown that lesbian women and gay men tend to have a greater difference in length between these two fingers, with the index finger being shorter than the ring finger, compared to heterosexual individuals. This has been attributed to differences in prenatal hormone exposure. Research on the other options (body shape, voice tone, amount of body hair) has not consistently shown clear differences between heterosexual individuals and those who identify as LGBTQ+.
