Direct effects of DBP and MBP on androgen biosynthetic and metabolizing enzyme activities in rat testes. Rat testis enzymes were measured with 50 μM DBP and MBP. The % activity of control was calculated. Mean ± SEM, ; , , and indicate significant difference when compared to control at , 0.01, and 0.001, respectively.
