There are many treatments for impotence, but before treating impotence, we must first make clear whether it is false impotence or psychological impotence. The general diagnostic standard of pseudoimpotence is that erectile function is normal at night, but it is impossible to have sex. The main reasons of psychological yang deficiency include the following aspects: First, the inhibition of excessive excitement before sexual life causes smooth muscle contraction and arterial congestion disorder. Second, lack of sexual skills, unfamiliar with the anatomical structure of male and female organs, prone to impotence after erection. Solution: First, take sildenafil orally before sexual life to improve the hardness of penis erection. Second, learn adult movies and gradually master sexual skills. Organic impotence, excluding psychological impotence, is generally due to abnormal arteriovenous function. The solution is to treat arteriovenous fistula with surgical ligation, venous impotence with vacuum negative pressure device and arterial congestion with prosthesis implantation.
