The first thing you need to do is to have an erectile dysfunction, which is the so-called “impotence”, whenever you want to have intercourse under sexual stimulation, the penis can not get an erection, or erection is not firm, or erection can not be maintained long enough to complete satisfactory intercourse. The first thing you need to do is to get a good idea of what you are getting into. Some sildenafil component of the drug to take, of course, with the introduction of such drugs, the basic treatment of erectile dysfunction has been a very good improvement. However, there are many kinds of treatments for male erectile dysfunction other than medication. Medication cannot solve the ailments of all erectile dysfunction patients, and it is necessary to understand the advantages and disadvantages of several more methods. Medication is preferred, safe and effective Oral medication is safe, non-invasive and easily accepted by patients. In particular, PDE5-I is 70-80% effective and has been proven to be safe and reliable through years of clinical research. Approved by the U.S. Food and Drug Administration (FDA), there are currently three selective PDE5 inhibitors on the market, namely sildenafil, vardenafil and tadalafil. Viagra is the representative of sildenafil drugs and is the most popular and widely used ED drug, and its therapeutic effect on ED is obvious to all. However, experts remind that Viagra needs to be taken in the right way to maximize its efficacy. It has been clinically found that many of the people who are ineffective in taking Viagra are caused by improper usage. A research group in Taiwan conducted a questionnaire survey for patients who claimed that taking Viagra was ineffective, and found that 1/3 of the patients did not have any sexual stimulation after taking the drug, 60% took it less than 4 times, and 45% of the patients did not take enough doses. The entry of Viagra into retail pharmacies is convenient for patients, but it is hoped that patients must take it in the correct way under the guidance of a doctor. Many people think that they will get an erection after taking Viagra, but this is actually not the case, and they need to be sexually stimulated after taking Viagra. Viagra does not “create” an erection, but only works when the patient is in a state of sexual stimulation. After taking Viagra, you need to be sexually stimulated in order to function. In addition, ED patients need to master the time of medication, generally 30 minutes to 1 hour before sex, older patients, due to the slow absorption of drugs, need to take an hour earlier. Secondly, taking Viagra also need to master the dose, Viagra first application of the recommended dose of 50 mg, 50 mg is not enough can be increased to 100 mg. Another non-invasive method available for treatment is vacuum negative pressure suction. When used this apparatus produces negative pressure on the penis, causing venous blood to flow into the penis while a visible strap is tied to the root of the penis, causing the cavernous body and penile skin to fill with blood resulting in penile enlargement. This method reduces venous blood flow back to the penis, but arterial blood flow is not increased. The disadvantage of negative pressure suction treatment is that it causes penile pain, paralysis and delayed ejaculation. Second-line treatment is very traditional and ineffective Intracavernosal vasoactive drug injections can be tried for patients who have failed first-line treatment, and this method can also be used for diagnosis as described earlier. There are many drugs that can be used alone or in combination for intracavernous injections (e.g., prostacyclin E1, phentolamine + vasoactive intestinal peptide, phentolamine + opiates, etc.). Patient comfort and giving patient instructions are essential. 60-90% of patients are treated effectively with injections. The penis starts to erect 5-15 minutes after injection and the duration is related to the drug dose. Common complications include pain at the penile injection site, abnormal erections, and long-term injections can lead to cavernous fibrosis. Other complications such as local hematoma, urethral bleeding, hypotension, etc. Abnormal erection is defined as persistent erection for more than 4 hours after injection. This may cause permanent ED by damaging the smooth muscle of the corpus cavernosum and needs to be treated promptly once it occurs. Intraurethral drug delivery (MUSE) is another minimally invasive second-line treatment. Prostacyclin E1 is available in a semi-solid pellet form and can be administered intraurethrally with a strap around the base of the penis to enhance erectile hardness. About 70% of patients are satisfied or very satisfied with this method, but there are some side effects, including penile pain and hypotension, and the clinical success rate is lower than that of intracavernosal injections. Surgical treatment is risky and should be considered carefully before surgery. For patients who do not respond to medication or wish to solve the problem once and for all, surgical implantation of a penile prosthesis may be considered. There are two types of prostheses: extensible and expandable. The expandable type better simulates the erection process and is more satisfying to the patient. Post-operative prosthesis infection is the main complication because the body’s rejection of the prosthesis is often combined with infection. Diabetic patients are usually the most susceptible to infection. Warm tip: specific medication please combine with clinical, by the doctor’s face to face guidance shall prevail.
