Patient: Dr. Tian, I saw from the Chutian Jinbao that you have opened a column called Male Disease Lecture, I would like to ask you a question, what kind of disease is impotence? Is there a good treatment? Doctor: When it comes to impotence, it is easy to associate the penis with being weak and firm. Impotence is a term used in Chinese medicine. In Chinese medicine, the penis is said to be the phallus, and the inability to lift the penis is, of course, impotence. The name impotence, although very graphic, is slightly derogatory, and modern medicine, from respect for human dignity, has renamed impotence as erectile dysfunction, abbreviated as ED. textbooks define ED as the inability of the penis to erect or maintain an erection sufficient to achieve satisfactory sexual intercourse. ED is a superficial phenomenon that is caused by many different causes, and the only good treatment is one that addresses the cause. The patient: Can you introduce me to the causes of impotence? The company’s main business is to provide a wide range of products and services to its customers. ED is a significant organic lesion or organ dysfunction, according to different causes, organic ED is divided into neurological ED, endocrine ED, vascular ED, drug ED, penile cavernous lesions, etc.. Neurological ED is caused by neurological lesions, such as high paraplegia, pelvic surgery resulting in pelvic nerve injury, urethral rupture resulting in cavernous nerve injury, etc. Endocrine ED is due to endocrine system dysfunction, such as hyperthyroidism, hypothyroidism, cortisolism, primary hypogonadism, secondary hypogonadism, etc. Vascular ED is the supply and drainage of the penile corpus cavernosum vascular lesions caused by insufficient arterial blood supply or venous closure can cause ED, the most common type is atherosclerosis. In many cases, ED is the result of many factors, such as diabetes mellitus can cause peripheral neuropathy and microangiopathy, so the ED caused by diabetes mellitus is both neurological and vascular. The ED is both neurological and vascular, and may even be interspersed with some psychological factors. Patient: I am an impotent patient, how do I know which cause I have? Doctor: It depends on the doctor’s diagnosis. The doctor’s detailed medical history and careful physical examination are important, in addition to some auxiliary tests. Patient: What are some of the ancillary tests? Doctor: Due to the limited space in this issue, I will leave this question to the next issue.
