Humans show intra- and intersexual variation in second (2D) relative to fourth (4D) finger length, men having smaller 2D:4D ratio, possibly because of differential exposure to sex hormones during fetal life. The relations between 2D:4D and phenotypic traits including fitness components reported by several studies may originate from the organizational effects that sex hormones have on diverse organs and their concomitant effect on 2D:4D. Evolutionary theory posits that sexual preferences are… 

Determinants of Hand Attractiveness—A Study Involving Digitally Manipulated Stimuli

Young women and men were presented with pairs of digitally manipulated images of opposite-sex hands and asked to indicate the hand perceived to be the more attractive in each pair, and adaptive and non-adaptive mechanisms underlying these preferences are discussed.

The Tell-Tale Hand

Abstract. The second-to-fourth digit ratio (2D:4D), an inconspicuous, but sexually differentiated anatomical trait (men present lower 2D:4D than women), has received intense research interest

An analysis of the sexual dimorphism of hands : atractiveness, symmetry and person perception

Relationships of Toe-Length Ratios to Finger-Length Ratios, Foot Preference, and Wearing of TOE Rings

The majority of toe-length ratios exhibited significant sex differences, which was similar to finger- length ratios, but of weaker effect size, and among women, feminized finger-length ratio corresponded to masculinized toe- lengths, however, these associations were directionally opposite.

Sex Differences in Relative Foot Length and Perceived Attractiveness of Female Feet: Relationships among Anthropometry, Physique, and Preference Ratings

The sex difference in relative foot length and inter-relations among foot length, physique, and foot preference ratings in samples from Austria and Canada were investigated and women with small feet preferred small feet in women in general.

Hand attractiveness—its determinants and associations with facial attractiveness

Hand and facial attractiveness was correlated with each other for each sex and mediated by shape typicality and fattiness in men and by grooming and, possibly, fattness in women.

Digit Ratio (2D:4D) and Wearing of Wedding Rings

Digit ratio (2D:4D), a putative marker for prenatal androgen levels, and absolute finger length, a marker for pubertal androgen action, were not associated with wearing of wedding rings in a sample

Avian hind‐limb digit length ratios measured from radiographs are sexually dimorphic

These findings show for the first time in avian species that sex differences in digit ratios have an osteometric basis, a fundamental prerequisite for a role of Hox genes in originating such dimorphism.

Perturbations in finger length and digit ratio (2D:4D) in ICSI children.



Sex hormones and finger length: What does 2D:4D indicate?

Examination marks of male university students positively correlate with finger length ratios (2D:4D)

Finger length ratio (2D:4D) correlates with physical aggression in men but not in women

Relative Lengths of Fingers and Toes in Human Males and Females

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.

Second to fourth digit ratio, testosterone and perceived male dominance

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.

Human digit ratios depend on birth order and sex of older siblings and predict maternal fecundity

2:4D and 4D:H may represent powerful tools to investigate the relationships between fetal environment, offspring phenotype and maternal life history at mechanistic and evolutionary levels and suggest that maternal fecundity co-varies with length ratios.

Relative digit lengths predict men’s behavior and attractiveness during social interactions with women

It is confirmed that male 2D:4D was significantly negatively correlated with women’s ratings of men”s physical attractiveness and levels of courtship-like behavior during a brief conversation, providing novel evidence for the organizational effects of hormones on human male attractiveness and social behavior.

Masculinized Finger Length Patterns in Human Males and Females with Congenital Adrenal Hyperplasia

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.
