Mr. Lu is in his middle age, is the boss of a private company, living in excellent conditions, but suffering from diabetes for many years, the current poor quality of sexual life, mainly short, his wife some complaints, so to the hospital to seek help from doctors. Through a detailed consultation, we learned that Mr. Lu’s erectile function also has a certain degree of decline, diabetes is prone to ED, because under the influence of high blood sugar, the relevant nerve fibers innervating the genitalia degenerate or nerve conduction dysfunction, the feeling of “information” and action “instructions “can not pass up and down, ED will also naturally occur. In addition, diabetes also involves the blood vessels of the penile corpus cavernosum, so that its diastolic function is impaired, the blood vessels can not be well filled, causing erectile dysfunction. The actual fact is that you can get a lot of the same things you need to do in order to be able to get a lot of the same things. After conducting the necessary tests, we developed a treatment plan for Mr. Lu, taking oral testosterone preparations to regulate endocrine secretion, in addition to using PED5 preparations to promote erection. Through a phase of treatment, Mr. and Mrs. Lu’s faces were smiling when they visited again. The percentage of premature ejaculation from diabetes is similar to that of the general population, so it is not certain that diabetes can directly cause premature ejaculation. Although there is no direct relationship between diabetes and premature ejaculation, because diabetic patients are prone to erectile dysfunction, patients fear that they will not be able to sustain an erection and therefore give up their weapons first, and the possibility of premature ejaculation symptoms cannot be ruled out. In the early stages of diabetes-induced sexual dysfunction, as long as the diet is controlled, reasonable medication, good control of blood sugar, to avoid further development of the disease, sexual function is expected to recover. If it reaches an advanced stage, nerve fiber degeneration and vascular sclerosis will be more difficult to cure. Therefore, early consultation, blood sugar control and prevention of complications is the best policy.
