    BACKGROUND. Anogenital distance (AGD), the distance from the centre of the anus to the genitals, is a sexually dimorphic phenotype in mammals. Experimental studies have shown that AGD is a biomarker of prenatal androgen exposure during the masculinisation period of development. The aim of this study is to assess the relationship between anogenital distance (AGD), as an indirect marker of prenatal hormonal environment, and prostate cancer (PCa) severity. MATERIALS. We conducted a cross-sectional study with a total of 120 PCa patients with confirmed biopsy of the tumour from April 2007 to July 2015. Two variants of the anogenital distance were assessed, from the anus to the posterior base of the scrotum (AGDAS) and to the cephalad insertion of the penis (AGDAP). We compared differences in groups to evaluate the association between AGD measurements and severity of the preoperative biopsy and clinical scores. RESULTS. Longer AGDAS was significantly associated with the highest Gleason score (P = 0.015) and D'Amico nomogram (P = 0.048). In contrast, no statistical differences were found in the AGDAP and severity of the preoperative biopsy. CONCLUSIONS. These findings are consistent with the hypothesis that a higher prenatal androgen exposure is associated with higher severity of PCa. Prostate.
