A decade old theory hypothesizes that brain exposure to androgens promotes involvement in criminal behavior. General support for this hypothesis has been provided by studies of postpubertal circulating levels of testosterone, at least among males. However, the theory also predicts that for both genders, prenatal androgens will be positively correlated with persistent offending, an idea for which no evidence currently exists. The present study used an indirect measure of prenatal androgen…

Results are consistent with the idea that prenatal androgen exposure reduces the 2D:4D and plays a role in the establishment of the sex difference in human finger length patterns, and finger lengths may offer a retrospective marker of perinatal androgens exposure in humans.

There were no strong associations between any adult circulating concentration of sex hormone or SHGB measured in adulthood and 2D:4D, and these results contribute to the growing body of evidence indicating that 2D:[4D]4D is unrelated to adult sex hormone concentrations.

The androgen-sensitive pattern of finger lengths is examined, and there is evidence that homosexual women are exposed to more prenatal androgen than heterosexual women are, and men with more than one older brother, who are more likely than first-born males to be homosexual in adulthood, are exposure to more pregnancies than eldest sons.

Current evidence for the relationship between digit ratios and prenatal androgen action is evaluated, opportunities for future validation tests are described, and the potential advantages and disadvantages of digit ratio measures are compared with more established methods for studying the effects of prenatal androgens.
