in addition to the histology of epithelial and stromal elements of prostates from intact dogs ( group 0 ) and castrated dogs ( group i ) , the latter of which were treated with androstenedione ( group ii ) , androstenedione plus the aromatase inhibitor 1-methyl-1,4-androstadiene-3,17-dione ( group iii ) , or androstenedione plus aromatase inhibitor and cyproterone acetate ( group iv ) ( habenicht and el etreby : the prostate 11:133-143 , 1987 ) it was of interest to study the influence of such in vivo treatment on the prostatic 5 alpha-reductase , which is responsible for the cellular conversion of testosterone to 5 alpha-dihydrotestosterone .
