“…Evidence regarding total finger ridge count is inconsistent: prenatal testosterone treatment in monkeys affected total count, but only if it was given early and, opposite to expectation, was associated with lower ridge count [269]; females with CAH had higher ridge count than controls in one study [270], but not in another [271], but both had small samples. There is no direct evidence for testosterone effects on fingerprint asymmetry: several measures of asymmetry were reported to be related to circulating testosterone in 39 adult males, and taken to provide indirect support for effects of prenatal testosterone, but there are no direct data showing that postnatal levels of sex hormones reflect prenatal levels of those hormones.…”

There is now good evidence that human sex-typed behavior is influenced by sex hormones that are present during prenatal development, confirming studies in other mammalian species. Most of the evidence comes from clinical populations, in which prenatal hormone exposure is atypical for a person's sex, but there is increasing evidence from the normal population for the importance of prenatal hormones. In this paper, we briefly review the evidence, focusing attention on the methods used to study behavioral effects of prenatal hormones. We discuss the promises and pitfalls of various types of studies, including those using clinical populations (concentrating on those most commonly studied, congenital adrenal hyperplasia, androgen insensitivity syndrome, ablatio penis, and cloacal exstrophy), direct measures of hormones in the general population (assayed through umbilical cord blood, amniotic fluid, and maternal serum during pregnancy), and indirect measures of hormones in the general population (inferred from intrauterine position and biomarkers such as otoacoustic emissions, finger length ratios, and dermatoglyphic asymmetries). We conclude with suggestions for interpreting and conducting studies of the behavioral effects of prenatal hormones. q

“…Polymorphism in the estrogen receptor-α gene accounted for some variance (11%) in digit ratios of birds (32), although there is evidence that the epidermis only has androgen receptors, but not estrogen receptors-α (33). Moreover, testosterone injection experiments in primates during early gestational age have evidenced male-typical changes in dermatoglyphic variables (34) and in ventral, but not bone, 2D:4D ratios (35). It is therefore possible that prenatal testosterone has effects on both the bones and the epidermis, whereas estrogen effects are limited to the bones.…”

Sexual Dimorphism in Digit Ratios Derived from Dorsal Digit Length among Adults and Children

Sexual dimorphism in ventrally measured digit ratios (2D:4D and other) has been related to prenatal sex-hormone levels. In the present series of three studies, we measured all digit lengths (excluding the thumb) on the dorsal, rather than the ventral, side of left and right hands and investigated the sexual dimorphism in digit ratios in three independent samples, two of them comprising adults (Study I, N = 104; Study II, N = 154), and one further, comprising kindergarten children (Study III, N = 64). Results show that men have lower digit-ratio values compared to women in digit ratios that include digit 5 as one of the constituents of the ratio (i.e., the 4D:5D, 3D:5D, and 2D:5D ratios). Boys have lower values compared to girls for the 4D:5D and 3D:5D ratios, and there is a similar trend of sexual dimorphism in the 2D:5D ratio. Thus, based on the evidence from dorsally measured digit ratios, the present findings from three samples are consistent with the idea that early sex-hormonal effects might be stronger for digit ratios involving digit 5, as compared to the classic, and frequently studied, ventrally measured 2D:4D ratio.

“…It may be hypothesized that only minutiae that depends on finger size and or/ masculinity respond to effect of testosterone. This is due to the fact that level of testosterone correlated positively with symmetry and fingerprint ridges (Jamison et al, 1994). That leads to expression of low asymmetry in male compared to females.…”

“…It was reported that dermatoglyphic asymmetries are related to adult testosterone (Jamison et al, 1993). In another separate study pregnant Rhesus positive mothers exposed to testosterone tend to have offspring with fewer dermal ridges than controls (Jamison et al, 1994). Since men have higher average ridge number than women it is generally suggested that higher levels of androgens may lead to an increased complexity in ridge patterns and a higher ridge count (Mustanski et al, 2002).…”

The present study was aimed at determining the existence of FA in Hausa populations using thumbprint minutiae. The participants included 112 males and 105 females of Hausa Ethnic descent, aged between 18-25 years. The minutiae of the plain thumbprints were determined from a circle with radius that cut across the nucleus of the fingerprints. The result showed that in signed asymmetry bifurcation, crossbar, break, point/dot into ridges and point/dot between ridges exhibited sexual dimorphism. The left ward asymmetry in male was exhibited in bifurcation, cross bar, trifurcation bifurcation, break, bridge, opposite bifurcation, in "M" convergence, in "M" bifurcation and Point/Dot into ridges. Similarly, in female bifurcation, trifurcation bifurcation, enclosure big, opposite bifurcation, convergence, in "M" bifurcation and return exhibit left ward asymmetry. For absolute and composite asymmetry the significant differences was observed in end, enclosure (small), bridge and return. In the entire minutiae types only ridge bifurcation exhibited directional asymmetry in males and six other minutiae types in females. In conclusion, the presence of sexual dimorphism in thumbprint ridge minutiae was demonstrated in the present study. The leftward asymmetry was observed in both sexes in different types minutiae. Females were observed to exhibit directional type of asymmetry more than the males in this population.
