But don’t worry if you don’t fit the picture – lots of things other than androgen exposure affect both finger length and the traits mentioned here. These hormones have masculinising effects. Why? Your digit ratio reflects the extent of your exposure to male sex hormones (eg testosterone) while still a foetus. 05) and mean 2D:4D did not change with gestational age (Malas et al., 2006). Straight women (and gay men) with higher digit ratios prefer partners with more masculine faces. The 2D:4D ratio was significantly higher in females compared to males (p <. Men with higher ratios do better in exams but are more likely to have paranormal and superstitious beliefs. People with higher digit ratios tend to score higher for the personality trait of agreeableness (ie they’re just nicer people). Men with lower ratios are perceived as more masculine and dominant and – among professional musicians – more skilled than their high-ratio counterparts (unsuprisingly, the authors didn’t ask people to rate women for their masculinity). Hand dominance or handedness has also been suggested to be a marker of in utero testosterone exposure and therefore few studies have explored the relationship between the 2D:4D ratio and. They are also more likely to have “masculine” handwriting (whatever that looks like). Men with lower (masculine) 2D:4D ratios showed lower aggression scores while men with higher (feminine) ratios scored higher on a test for depression 2,10. In the literature, to the best of our knowledge, only one pre-vious study has investigated this relation in line with our ndings, those authors found a higher right-hand 2D:4D ratio in the bipolar disorder group. Endocrinology, 150(11), 5119–5124.People with lower digit ratios tend to be more assertive, perhaps even more aggressive, and are less likely to suffer from eating disorders. our sample, the right-hand 2D:4D ratio was higher in the bipolar disorder group than in the control group.

Several studies suggest that both men and women with lower 2D:4D ratios tend to be more promiscuous than men and women with higher 2D:4D ratios, suggesting prenatal exposure to testosterone can influence sexual behavior into adulthood. Diagnostic and statistical manual of mental disorders (5th ed.). Women with lower 2D:4D have higher waist-to-hip ratio, are more masculine, and are more athletic (Csathó et al., 2003a Manning et al., 2000 Pokrywka et al., 2005). FtM GD patients showed significantly masculinized right-hand 2D:4D ratios, while there was no evidence of feminization in MtF GD patients.ĢD:4D Digit ratio Gender dysphoria Prenatal androgen exposure Sexual orientation Siblings.Īmerican Psychiatric Association. There was no significant difference in left-hand 2D:4D ratios between MtF GD patients, and their brothers, or female and male controls. There were significant sex differences in 2D:4D and occupational preference. MtF GD patients had lower right-hand 2D:4D ratios than female controls (p <.001), but their right-hand ratios did not differ from those of their brothers and male controls. Men and women provided information about interest in occupations and rated themselves on Masc/Fem. While there was no significant difference in right hands between FtM's sisters and male controls, left-hand 2D:4D ratios were significantly higher in FtM's sisters (p =. FtM GD patients had no significant difference in their left-hand 2D:4D ratios compared to their sisters or female and male controls. 001) but their ratios did not differ from those of their sisters or male controls. Regarding right hands, FtM GD patients had lower 2D:4D ratios than female controls (p <. 003) were lower in male controls than in female controls. We found that 2D:4D ratios in the both right hand (p <. FtMs were gynephilic and MtFs were androphilic. Sixty-eight GD patients (46 Female-to-Male 22 Male-to-Female ), 68 siblings (46 sisters of FtMs 22 brothers of MtFs), and 118 heterosexual controls (62 female 56 male) were included in the study. ![]() We compared gender dysphoria (GD) patients and their same-sex siblings in terms of their 2D:4D ratios, which may reflect prenatal exposure to androgen, one of the possible etiological mechanisms underlying GD. ![]()
