|abstract=Previous in vitro studies have demonstrated that the UDP glucuronosyltransferase (UGT)2B15 and [[UGT2B17]] glucuronidate androgens and their metabolites. Our objective was to determine in vivo whether the [[UGT2B15]] D85Y and the [[UGT2B17]] deletion polymorphisms predict androgen glucuronidation and body composition. Two population-based cohorts including young adult (n = 1068; age = 18.9 yr) and elderly (n = 1001; age = 75.3 yr) men were included in the study. Serum and urine levels of testosterone (T) and dihydrotestosterone (DHT) were measured by gas chromatography-mass spectrometry, and serum levels of the major glucuronidated androgen metabolites androstane-3alpha,17beta-diol(androstanediol)-3-glucuronide, androstanediol-17-glucuronide, and androsterone-glucuronide were measured by liquid chromatography-tandem mass spectrometry. Body composition was measured by dual-energy x-ray absorptiometry. Both the [[UGT2B15]] D85Y and the [[UGT2B17]] deletion polymorphisms were associated with serum levels of androstanediol-17-glucuronide (P < 0.001) but not with levels of androstanediol-3-glucuronide or androsterone-glucuronide in both cohorts. Glucuronidation of T and DHT was associated with the [[UGT2B17]] deletion but not with the [[UGT2B15]] D85Y polymorphism, suggested by strong associations between the deletion polymorphism and urine levels of these two hormones. Both polymorphisms were associated with several different measures of fat mass (P < 0.01). The [[UGT2B17]] deletion polymorphism was associated with insulin sensitivity (P < 0.05) as indicated by the homeostasis model assessment index. The [[UGT2B15]] D85Y and the [[UGT2B17]] deletion polymorphisms are both predictors of the glucuronidation pattern of androgens/androgen metabolites. Our findings indicate that [[UGT2B17]] is involved in 17-glucuronidation of mainly T but also of DHT and androstanediol and that [[UGT2B15]] is involved in the 17-glucuronidation of androstanediol. Furthermore, these two polymorphisms are predictors of fat mass in men.
