2D:4D Finger Length Ratios in Individuals with Gender Dysphoria.
TLDR
Evidence is presented that the AFB-GD individuals were exposed to testosterone in the prenatal period, and the 2D:4D digit ratio, which is considered to be a morphological indicator of exposure to testosterone at birth, in individuals with GD.
2D:4D Digit Ratios in Adults with Gender Dysphoria: A Comparison to Their Unaffected Same-Sex Heterosexual Siblings, Cisgender Heterosexual Men, and Cisgender Heterosexual Women.
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…
Prenatal Influences on Sexual Orientation: Digit Ratio (2D:4D) and Number of Older Siblings
Prenatal androgen levels are suggested to influence sexual orientation in both sexes. The 2D:4D digit ratio has been found to associate with sexual orientation, but published findings have often been…

TLDR
The findings are consistent with a biologic basis for transgender identity and the possibilities that FTM gender identity is affected by prenatal androgen activity but that MTF transgender identity has a different basis.
The relationship between second-to-fourth digit ratio and female gender identity.
TLDR
The finger length ratio 2D : 4D in GID-FtM was significantly lower than in female controls in the right hand and 2D: 4D showed a positive correlation with GIS score.
2D:4D Suggests a Role of Prenatal Testosterone in Gender Dysphoria
TLDR
The findings support the idea that high levels of prenatal T in natal females and low levels inNatal males play a part in the etiology of GD, and add to the evidence demonstrating the convergent validity of 2D:4D as a marker of prenatalT effects.
An anthropometric study of sexual orientation and gender identity in Thailand
TLDR
It appears the various anthropometrics inform separate biodevelopmental processes that differentially relate to sexual orientation and gender identity/expression depending on the measure in question as well as birth-assigned sex.
Digit ratio (2D:4D) and transgender identity: new original data and a meta-analysis
TLDR
This original investigation and the updated meta-analysis clarify the association between transgender identity and 2D:4D indicating the influence of prenatal androgen on the development of gender identity in subjects born as males.
The Relationship Between Digit Ratio (2D:4D) and Sexual Orientation in Men from China
We examined the relationship between 2D:4D digit ratio and sexual orientation in men from China and analyzed the influences of the components used to assess sexual orientation and the criteria used…
Sexual Dimorphism of Digit Ratio (2D:4D) in Madhya Pradesh
TLDR
It is suggested that the 2D:4D ratio is a constant feature among different age groups in different population, which will prove useful to determine sex when more reliable means of sex estimation are not available during medicolegal examination.

Finger Length Ratio (2D:4D) in Adults with Gender Identity Disorder
TLDR
The results indirectly point to the possibility of a weak influence of reduced prenatal testosterone as an etiological factor in the multifactorially influenced development of MtF GID, where the development of FtM GID seems even more unlikely to be notably influenced by prenatal testosterone.
Typical female 2nd–4th finger length (2D:4D) ratios in male-to-female transsexuals—possible implications for prenatal androgen exposure
Sexual Dimorphism in the Prenatal Digit Ratio (2D:4D)
TLDR
The 2D:4D ratio, thus, seems to increase after birth in both men and women, with the second digit growing faster than the fourth digit (positive allometric growth of digit two) and perhaps more so in women than in men.
On the Relation Between 2D:4D and Sex-Dimorphic Personality Traits
TLDR
The 2D:4D digit ratio may be a valid, though weak, predictor of selective sex-dependent traits that are sensitive to testosterone.
Masculinized Finger Length Patterns in Human Males and Females with Congenital Adrenal Hyperplasia
TLDR
Results are consistent with the idea that prenatal androgen exposure reduces the 2D:4D and plays a role in the establishment of the sex difference in human finger length patterns, and finger lengths may offer a retrospective marker of perinatal androgens exposure in humans.
A follow-up study of girls with gender identity disorder.
TLDR
The rates of GID persistence and bisexual/homosexual sexual orientation were substantially higher than base rates in the general female population derived from epidemiological or survey studies and there was some evidence of a "dosage" effect, with girls who were more cross-sex typed in their childhood behavior more likely to be gender dysphoric at follow-up and to have been classified as bisexual/Homosexual in behavior.
Psychosexual outcome of gender-dysphoric children.
TLDR
Both boys and girls in the persistence group were more extremely cross-gendered in behavior and feelings and were more likely to fulfill gender identity disorder (GID) criteria in childhood than the children in the other two groups.

Relative Lengths of Fingers and Toes in Human Males and Females
TLDR
For both homosexual females and homosexual males, nearly all of the length ratios for fingers were intermediate to those for heterosexual females and heterosexual males; that is, the ratios of homosexual females were masculinized and those of homosexual males were hypomasculinized, but few of these differences were significant.
