Insufficient blood supply to the penis is the most common cause of male erectile dysfunction, usually due to lesions of the corpus cavernosum or penile vascular lesions, which can be clearly diagnosed through penile blood flow Doppler examination. To restore the blood supply to the penis, oral medication, such as Rhodiola rosea capsules and Thromboxane tablets, can effectively improve the blood supply to the corpus cavernosum in 4-8 weeks of continuous treatment, and the erectile function of the penis can be effectively restored. If oral medication is ineffective or there is obvious penile arteriovenous fistula, it is necessary to ligate the penile arteriovenous fistula through interventional surgery, or through the implantation of a prosthesis to improve the hardness of the corpus cavernosum, in order to alleviate the erectile dysfunction due to insufficient blood supply.
