Index-to-ring finger length ratio (2D:4D) predicts levels of salivary estradiol, but not progesterone, over the menstrual cycle.

چکیده
We tested the association between the index-to-ring finger length ratio (2D:4D) and ovarian steroid hormone concentrations measured over the course of a menstrual cycle in the saliva of 38 young women. Estradiol levels were positively associated with right-hand, but not left-hand, 2D:4D, and also with the difference between right- and left-hand 2D:4D. None of these measures predicted progesterone level.

Background: Sex determination from human remains is a challenge for forensic experts. Many studies have shown that the finger length ratios might be characteristic for sexual dimorphism. The aim of this study was to determine sexual dimorphism in finger length ratios among Iranian population. Methods: The study group comprised of a random sample of 100 healthy people without congenital or acqu...
متن کاملSex Hormones and Choice under Risk∗
We correlate choice under risk in Holt-Laury lottery tasks for gains and losses with salivary testosterone, estradiol, progesterone, and cortisol, the use of hormonal contraceptives, menstrual cycle information as well as the digit ratio (2D:4D) in more than 200 subjects. Risk aversion is negatively correlated with testosterone and positively correlated with cortisol, a stress hormone, for gain...
متن کاملFinger lengths, 2D:4D ratios, and their relation to gender-related personality traits and the Big Five.
Finger lengths and the ratio of index finger to ring finger length (2D:4D) may be markers of gonadal hormone exposure. The current study investigated possible associations between absolute finger lengths, 2D:4D ratios, and gender-related personality traits in over 2000 participants. Regression analyses showed no associations between men's 2D:4D ratios and gender-related personality traits and w...
متن کاملReplicated nil associations of digit ratio (2D:4D) and absolute finger lengths with implicit and explicit measures of aggression.
Preliminary evidence suggests that within-sex individual variation in the length ratio of the index finger to the ring finger (2D:4D), a putative marker of prenatal androgen levels, may be more strongly or consistently related to implicit measures (Implicit Association Test, IAT) than to corresponding explicit (self-report) measures of candidate personality traits. The underlying logic is that ...
