The original prescription has been used to treat erectile dysfunction(ED), while the detailed indications and specific treatment mechanisms of Ela tablets remain unclear. In the present study, we aimed to investigate whether Ela tablets could protect mice from ED caused by repeated restraint stress and to explore the possible mechanisms. Mice were restrained daily in centrifuge tubes with venting holes for 14 consecutive days and administered Ela tablets at 1 h before restraining. On the 14 th night, mating experiments were conducted. Thereafter, blood, testicular, and penile samples were collected. Serum testosterone levels were measured using a kit. Testicular tissue morphology was observed by H&E staining. The PDE5 expression in the corpus cavernosum was measured by Western blotting analysis. The results indicated that Ela tablets significantly shortened the sexual arousal time, increased the number of sexual encounters, maintained the normal morphology of testicular tissue, increased the serum testosterone levels, and decreased the PDE5 expression in the corpus cavernosum. Our data showed that Ela tablets elicited protective effects on the sexual ability of mice exposed to repeated restraint stress. Moreover, the underlying mechanism was related to the preservation of testicular tissue morphology, maintenance of testosterone levels, and inhibition of penile PDE5 expression.展开更多
