• The relationships of digit ratio (2D:4D) with the length of AR (CAG)n, and testosterone levels from saliva and blood have been extensively debated over the years. This research including three studies further clarifies such controversies. To do so, we re‐examined the relationships between the length of AR (CAG)n, 2D:4D, and current testosterone levels, through replication study and meta‐analysis for each study. The results indicate: (a) the length of AR (CAG)n is not significantly associated with 2D:4D; (b) current testosterone levels are not significantly associated with the ratio; and (c) the length is not significantly associated with testosterone levels. Thus, AR (CAG)n and current testosterone levels are not significantly related to 2D:4D at individual level. The results from study 1 indicated that the length of AR (CAG)n is not significantly associated with 2D:4D; the results from study 2 show that current testosterone levels are not significantly associated with 2D:4D; and according to study 3, the length is not significantly associated with testosterone levels.
