Figure 2: Effect of BPME and BPEAF on mRNA expression corresponding to 3β-HSD and StAR in testicular tissues (n=6 in each group). Values are expressed as mean±SD. *P<0.05 and **P<0.01 compared to the normal control group. 3β-HSD: 3β-hydroxysteroid dehydrogenase; StAR: steroidogenic acute regulatory protein.
