Ribeiro E Jr, Neave N, Morais RN, Kilduff L, Taylor SR, Butovskaya M, Fink B, Manning JT   Abstract   BACKGROUND: Digit ratio (2D:4D) is a putative marker for prenatal testosterone and is correlated with performance in many sports. Low 2D:4D has been linked to strength but the evidence is mixed and strength is also influenced by mass, testosterone, and behavioural factors. It has been hypothesised that the 2D:4D-strength correlation may be strongest in challenge conditions when short-term changes occur in steroid hormones.   AIMS: We tested this suggestion in men.   STUDY DESIGN: We used a cross-over study design with a challenge (an
