The penis becomes soft after a short erection

An adult male's penis should feel very powerful and his whole body excited after an erection, but some people may feel their body go limp and their legs may even tremble after an erection. Symptoms like these are mostly caused by kidney deficiency or excessive physical exertion. It is necessary to find out the cause and give appropriate treatment to help recovery.

There are many causes of erectile dysfunction, but they can be generally classified into two categories. One is psychological erectile dysfunction; the other is organic erectile dysfunction. In the past, it was believed that 80% to 90% of erectile dysfunction was a psychological disorder, but in recent years, with the continuous development of science, research has become more in-depth, and it has been found that organic lesions are on the rise, exceeding 15% to 40%, and some patients have multiple organic lesions. With age, sexual function will change in quality and quantity, and erectile dysfunction will also increase. The incidence rate is reported to be 7% before the age of 55; it can increase to 18.5% to 75% after the age of 60.

Among endocrine diseases, especially diabetes, erectile dysfunction is 2 to 5 times higher than other people. Its pathogenesis is mainly due to neurological and vascular lesions caused by metabolic abnormalities. There are also primary hypogonadism, thyroid, adrenal, pituitary dysfunction, nervous system diseases, vascular diseases, systemic diseases, smoking, alcoholism and other bad habits. In addition, many drugs can cause erectile dysfunction. Common drugs that affect sexual function include antihypertensive drugs such as pheniramine, methyldopa, reserpine, propranolol, clonidine, phentolamine, etc.; heart disease drugs include digoxin, coronary artery disease, etc.; diuretics include spironolactone, furosemide, etc.; antipsychotic and sedative drugs include diazepam, amitriptyline, phenothiazines, etc.; antiandrogen drugs include estrogen, progesterone, gonadotropin-releasing hormone, ketoconazole, etc.; in addition, there are barbiturates, phenytoin sodium, cimetidine, indomethacin, antihistamines, etc.
