Fink et al. (2006) have reported that men with higher grip strength (GS) have lower digit ratios (2D:4D), interpreting this as evidence for organizational effects of prenatal androgens on strength. In this study, I attempted to replicate their finding with 99 women. I found no evidence that digit ratios were associated with GS, suggesting that 2D:4D is not associated with GS in women. The null findings are discussed in light of gender and statistical considerations.Am. J. Hum. Biol. 19:437–439, 2007. © 2007 Wiley-Liss, Inc.
