(3alpha,5alpha)-3-[(2,5-dimethyl-4-{[2-(trifluoromethyl)phenyl]sulfonyl}piperazin-1-yl)methyl]-3-hydroxyandrostan-17-one
the inhibitor RM-532-105 seems to have difficulties in penetrating inside the testis and is concentrated in the testicular capsule. Therefore it is unable to inhibit the 17bets-HSD3 located inside the testis. At a higher concentration, RM-532-105 significantly decreases the level of testosterone and dihydrotestosterone in rat plasma, in vivo effects of the inhibitor in testis and plasma, detailed overview

activities of the two key enzymes for testosterone biosynthesis, 3-beta-HSD and 17-beta-HSD, are significantly affected by rats subjected to semi-synthetic diet. Both enzyme activities are significantly decreased in interstitial cell homogenates from rats fed with a soybean diet and a grape seed diet compared with the levels observed in the group fed a olive or coconut diet

male pigs with high androstenone concentrations in fat have low 3betaHSD gene expression in liver and testis. Immunocastrated and surgically castrated male pigs shows significant increase of 3betaHSD expression. Fat androstenone is negatively correlated with liver 3betaHSD gene expression.
