Digit ratio (2D:4D) and behavioral differences between inbred mouse strains

TLDR
Large differences in digit ratio between the strains are found and it is suggested that inbred mice are a promising system for investigating the correlation between digit ratio and behavioral traits.

Digit ratio ( 2 D : 4 D ) and behavioral differences between inbred mouse strains

TLDR
Large differences in digit ratio between the hind paw digit ratio in mice of eight inbred strains are found and it is suggested that inbred mice are a promising system for investigating the correlation between digit ratio and behavioral traits.

Varsity athletes have lower 2D:4D ratios than other university students

TLDR
A smaller 2D:4D ratio appears to be consistent with participation in varsity sports among both males and females, and that male athletes had significantly lower ratios than female athletes.

Study of Aggressive Behavior of an Individual from Ratio of Index and Ring Fingers' Length

TLDR
Physical aggression is more in male but verbal aggression, anger and hostility are more in female and ratio of index finger and ring finger (2D:4D) is higher in female.

2D:4D Ratios and FA 1 Running head: AGGRESSION, FINGER LENGTH RATIOS, AND FLUCT UATING Aggression, Finger Length Ratios, Fluctuating Asymmetry, a nd Verbal/Spatial Abilities in Male and Female College Students

The 2D:4D (second to fourth digit) ratio is thought to be a measure of prenatal testosterone exposure, and has been linked to traits such as aggression, sexual tendencies, and verbal/spatial

Sex Differences in 2D:4D Rations, Aggression, and Spatial/Verbal Abilities

Finger length ratios (2D:4D) in anthropoids implicate reduced prenatal androgens in social bonding.

TLDR
Test the relationship between digit ratios and behavior across nonhuman anthropoids; polygynous species, with higher levels of intrasexual competition, should have more pronounced markers of PAE (lower 2D:4D) than pair-bonded species, and results accord with those found in humans.

Sexual dimorphism in digit‐length ratios of laboratory mice

TLDR
The mouse may be a useful animal model for studying the factors that influence finger length patterns, which have recently been correlated with several specific behaviors and disease predispositions in humans.

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.

Second to fourth digit ratio, testosterone and perceived male dominance

TLDR
High prenatal levels of testosterone serve to ‘organize’ male facial features to subsequently reflect dominance and masculine characteristics presumably activated during puberty, and attractiveness is not directly related to testosterone levels.

Differences in Finger Length Ratios Between Self-Identified “Butch” and “Femme” Lesbians

TLDR
It is concluded that increased early androgen exposure plays a role in only some cases of female homosexuality, and that the sexual orientation of “femme” lesbians is unlikely to have been influenced by early androgens.

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.

In-utero androgen exposure and 2nd to 4th digit length ratio-comparisons between healthy controls and females with classical congenital adrenal hyperplasia.

TLDR
2D:4D ratios determined directly from radiographs of the left hand confirm significant differences between males and females, however, female patients with virilizing CAH do not have a male digit ratio pattern suggesting that in theleft hand digit ratio development is not influenced by in-utero exposure to androgens.

Sex-Specific Finger-Length Patterns Linked to Behavioral Variables: Consistency across Various Human Populations

TLDR
With samples from Brazil, Canada, India, Turkey, and Korea, it was shown that patterns of distal extent of finger tips are similar across different human populations, and consistent sex differences were found across the samples.

Finger-length ratios and sexual orientation

TLDR
The androgen-sensitive pattern of finger lengths is examined, and there is evidence that homosexual women are exposed to more prenatal androgen than heterosexual women are, and men with more than one older brother, who are more likely than first-born males to be homosexual in adulthood, are exposure to more pregnancies than eldest sons.
