The Relationship of Digit Ratio (2D:4D) and Gender-Role Orientation in Four National Samples
Abstract. The ratio of second to fourth finger length (2D:4D ratio) is sexually dimorphic with women having higher 2D:4D ratio than men. Recent studies on the relationship between 2D:4D ratio and
It is argued that assortative mating on 2D:4D operates indirectly and may be mediated through the assortment on other, more perceptible, physical traits and psychological phenotypes that entertain associations with 2D-4D and are relevant for courtship and mate choice.
Intrauterine Position Effects on Anogenital Distance and Digit Ratio in Male and Female Mice
The lack of correlation between 2D:4D and AGDs in this mouse strain suggests that these two measures do not reflect a common influence of androgen exposure, and the possible roles of temporal and localized effects of masculinization are discussed.
Digit ratio ( 2 D : 4 D ) and gender role orientation in health and medical students
The ratio of index finger length to ring finger length(2D:4D) is an index of prenatal testosterone and /or estrogen exposure. The aim of this study is to investigate digit ratio and the type of
Anxiety, Sex-linked Behavior, and Digit Ratios
The second to fourth (2D:4D) digit ratio, a sexually dimorphic, phenotypic characteristic putatively associated with perinatal androgen action, has been used to evaluate the hypothesized relation
Relationship between second to fourth digit ratio (2D:4D) and academic performance among students in Nigeria.
The second to fourth digit ratio (2D:4D), is a sexually dimorphic trait, with males on the average having lower ratios than females 2D:4D. It had been correlated with several psychosocial features.

Finger-length ratios and sexual orientation
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.
Relation between testosterone concentration, sex role identity, and personality among females.
Adjectival correlates indicated that females with higher testosterone concentrations perceive themselves as self-directed, action-oriented, resourceful individuals; women with lower testosterone concentration view themselves as conventional, socialized individuals, possessing a caring attitude coupled with an anxious and dejected mood.
The 2nd:4th digit ratio and asymmetry of hand performance in Jamaican children
Testosterone, particularly prenatal testosterone, has been implicated in the aetiology of many extragenital sexually dimorphic traits and it is suggested that the 2D:4D ratio may be associated with the expression of other sexuallyDimorphic behavioural traits.
The ratio of 2nd to 4th digit length: a new predictor of disease predisposition?
Prenatal levels of testosterone and oestrogen have been implicated in infertility, autism, dyslexia, migraine, stammering, immune dysfunction, myocardial infarction and breast cancer and it is suggested that 2D:4D ratio is predictive of these diseases.

The results of the meta-analysis were most supportive of the masculinity model and showed that the strength of observed relations between sex role orientation and self- esteem varied as a function of both the sex role measure and the type of self-esteem measure used in the studies.
Human behavioral sex differences: a role for gonadal hormones during early development?
The evidence is strongest for childhood play behavior and is relatively strong for sexual orientation and tendencies toward aggression, and high levels of hormones do not enhance intelligence, although a minimum level may be needed for optimal development of some cognitive processes.
