dc.identifier.citation(2015) Correlation between 2D:4D and 'Masculine' Characteristics, no. 37.
dc.description.abstractBackground: 2D:4D has been shown to be an indicator of prenatal testosterone exposure. In utero levels of the sex hormone are considered to have an affect on various sexual traits. 'Masculine' characteristics are considered a direct result of higher foetal testosterone exposure. Objectives: To investigate the role of pre-natal testosterone levels indicated through 2D:4D ratios in a QMU cohort. Testosterone exposure will be analysed in relation to digit ratio, spatial ability and sexual orientation. Study Method: The study compromises repeated 2D and 4D measurements of both hands. Subjects (n=65) are asked to complete a short demographic questionnaire, indicate sexual orientation on the Kinsey Scale and complete the SBST; answers to all are kept anonymous. Results are analysed using SPSS 21 and Excel 2010. Results: RH 2D:4D indicated a significant negative correlation between genders. 2D:4D of the RH was significantly associated with programme of study. No significance was found between gender and sexual orientation. Discussion: 2D:4D ratio is has been found to be possibly correlated with 'masculine' characteristics. Association has not been identified with all 'masculine' characteristics. However previous research has been reflected in the associations that have been observed. This study strengthens previous research; 2D:4D ratio can act as a possible indicator for prenatal testosterone exposure. Key words: 2D:4D, Testosterone, Prenatal
