There are many causes of erectile dysfunction in the penis, which may be caused by psychological causes, medications, hormonal abnormalities, neurological disorders, or vascular disease. Overview of treatment: 1. Identify the underlying cause, including medications that may cause or contribute to erectile dysfunction (ED), such as antidepressants or antihypertensives. Identify and treat cardiovascular risk factors, such as smoking, obesity, hypertension, and dyslipidemia, as both lifestyle measures to reduce risk factors and pharmacotherapy are sometimes effective in preventing and treating ED. 3. For first-line treatment, PDE-5 inhibitors are recommended because they are effective, easy to use and have a more desirable side effect profile. Sildenafil, vardenafil, tadalafil and the latest drug avanafil seem to be as effective, but the duration of action of tadalafil longer, avanafil may be more rapid onset of action. PDE-5 inhibitors are contraindicated in men who use nitrates, and PDE-5 inhibitors should be used with caution in men who receive an alpha adrenergic receptor blocker. 4, Use testosterone replacement therapy for men with ED and definite low testosterone serum levels (i.e., hypogonadism), unless the patient has a contraindication. 5, If PDE-5 inhibitors are ineffective, negative pressure devices, penile injection drugs and intraurethral prostil may be used as second-line therapy. 6. For men who cannot use first- and second-line treatment options or for whom these treatments are ineffective, surgical implantation of a penile prosthesis may be used, but some patients will choose penile prosthesis implantation directly as first-line treatment for a variety of reasons. 7, for men whose ED is caused by depression or anxiety, psychotherapy alone or a combination of psychotherapy and psychotropic drugs can be used. 8, lifestyle changes – lifestyle changes (weight loss, physical activity) and cardiovascular risk factors of medical treatment can be effective in improving the sexual function of some men with ED. 9, because the above first-line, second-line treatment and surgical treatment have certain side effects, you can also first try Chinese medicine such as compound Xuanju capsule treatment. Also pay attention to not too strenuous, do not sit for a long time, do not drive for a long time, do not stay up late, appropriate exercise exercise. Do not drink alcohol and do not eat spicy food.
