Second to fourth digit ratio: A predictor of adult lung function
Sex and sex hormones play a major role in lung physiology. It has been proposed that the ratio of the second to fourth digits (digit ratio) is correlated with fetal sex hormones. We therefore hypothesized that digit ratio might help predict lung function. We investigated the relationship between digit ratio and pulmonary function test (PFT) findings. A total of 245 South Korean patients (162 ma...
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 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...
متن کاملAssociation between Second to Fourth Digit Ratio with Handwriting Quality and Speed among Elementary School Children
Background Genetic impacts on handwriting legibility and speed, especially in early childhood, are not well understood. The present study used a 2D:4D ratio as a biological marker to investigate the associations between genetic factors with quality and speed of handwriting among the elementary school children. Ma...
متن کاملM.b. Wieling - Second-to-fourth Digit Ratio Related to Jealousy
The ratio of index finger length to ring finger length (2D:4D) is an index of prenatal androgen exposure. The larger the exposure to androgens, the smaller this ratio will be. Androgens “masculinise” people and may influence individual differences in a predictable way. In a study with 109 participants, 46 men and 63 women, the relationship between 2D:4D and jealousy was assessed. In a jealousy ...
