The protein level of the dopamine D2 and D3 receptors of male rats in all studied groups were detected by Western blots. A The electrophoretic band of D2/D3 and the reference gene, actin. B The value of gray analysis of D2/D3 to actin. Student’s T test was used to compare the statistical difference between two groups. **p < 0.01, ***p < 0.001, indicate a significant difference. Drd2/Drd3, dopamine D2/D3 receptors; PE, premature ejaculation; Sul, sulpiride; SY, Shugan Yidan fang
