The hardness of the penis is the state of erection. If the hardness of the penis is not enough, it is because there is a problem with the erectile function of the penis, which means impotence. It can be regulated by Chinese patent medicines, such as Wu Zi Yan Zong Wan, Jin Kui Kidney Qi Wan, Qilin Wan, Liu Wei Di Huang Wan, and Yu Gui Wan, which have the effect of tonifying the kidneys and strengthening the yang, and have a certain effect against the change of penis hardness. However, while using these drugs, patients also need to combine other complementary treatment measures, such as avoiding staying up late, quitting smoking and alcohol, preventing excessive masturbation and having an appropriate frequency of sexual life. It is also necessary to prevent the occurrence of genitourinary infections, such as prostatitis and testicular epididymitis, which can also have an impact on the hardness of the penis. If you have any of these diseases, you must have an early examination and diagnosis, and have early treatment.
