Rat dorsolateral prostate 5alpha-reductase activity. Activity (mean ± SEM) of 5alpha-reductase was determined in dorsolateral prostates of rats fed the 0 Se supplement-10 mg/kg phytoestrogen diet, and compared with activity in rats fed the 3.0 mg/kg Se supplement-600 mg/kg phytoestrogen diet. *The combination of high levels of both dietary components significantly reduced enzyme activity (p < .001).
