Digit ratio and risk taking in post-menopausal Finnish women

Although an indicator of prenatal testosterone (PT), 2D:4D ratio, has been extensively studied in the domain of financial risk taking, other domains of risk have received less attention. It is thought that elevated levels of PT relate to more masculinised behaviours, including increased risk taking propensity. In this study, we report negative findings with regards to health (average weekly drinking and daily smoking) and sexual (lifetime number of sexual partners) risk in a sample of post-menopausal Finnish women (N = 146–262). Our results suggest that PT may not masculinise health and sexual risk taking in women, at least at an older age.
