Does digit ratio (2D:4D) predict penile length?
Now advertized in at least one locale as the ‘sexy ratio’ with the caption, ‘Your hands give away your hotness’ (http://io9.com/ #!5794008; accessed 3 May 2011), an online summary of a recent study linking facial attractiveness to the ratio of the index and ring fingers indicates that digit ratio (2D:4D) research has reached mainstream culture.

متن کاملSecond to fourth digit ratio: a predictor of adult penile length.
The second to fourth digit ratio (2D:4D) has been proposed as a putative biomarker for prenatal testosterone and covaries with the sensitivity of the androgen receptor (AR). Both prenatal testosterone and the AR play a central role in penile growth. In this study, we investigated the relationship between digit ratio and penile length. Korean men who were hospitalized for urological surgery at a...
متن کاملMaternal 2nd to 4th digit ratio does not predict lifetime offspring sex ratio at birth.
The low ratio of second-to-fourth digit length (2D:4D) of parents, a putative indicator of high prenatal and even adult testosterone levels, has been suggested to predict a male-biased secondary offspring sex ratio. We investigated this question in 244 contemporary postreproductive Finnish women. Information on the lifetime offspring birth sex ratio of women was collected by questionnaires and ...
متن کاملCan shoe size predict penile length?
OBJECTIVE To establish if the 'myth' about whether the size of a man's penis can be estimated from his shoe size has any basis, in fact.

متن کاملThe Ratio of Second to Fourth Digit Length (2D:4D) in Children with Autistic Disorder
Introduction Emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of Autism spectrum disorders (ASD). The ratios of the lengths of the bones of the 2nd to the 4th digits (2D:4D) are purported to be markers for prenatal androgen exposure and to be established early in gestation. Ratio of second and fourth digits (2D:4D) is usually used as a proxy for prenatal t...
