Current treatments can successfully treat impotence, but they cannot cure it. Only psychological impotence, post-traumatic arterial impotence in young patients and impotence due to hormonal causes (e.g., hypogonadism and hyperprolactinemia) may be cured. In case of mild impotence or psychological impotence, the patient may be cured by psychotherapy; however, for organic pathologies, such as impotence with severe diabetes, hypertension, hyperlipidemia, metabolic syndrome, etc., successful erection may be achieved by taking medication. For patients, as long as the drugs are effective, they can continue to take them, and there are no side effects of the drugs themselves, so don’t worry about that. An erection is an arterial blood vessel filling with blood, and a good erection relies on good vascular function. As people get older, the elasticity of blood vessels will become less and less, and people with high blood lipids will have narrower and narrower blood vessels, all of which will lead to a decrease in blood vessel function. A sign of declining vascular function is a bad erection. Psychological impotence is sometimes difficult to be cured by psychological guidance alone, and should be supplemented by medication such as Viagra. Sexual function also follows the principle of using in and out, which means that the more you use it, the better it works. Some psychological causes of impotence, if left untreated for a long time, the penis will cause fibrosis due to lack of oxygen and other reasons, which will lead to organic impotence. That is why sexual life to maintain a certain frequency (such as 2-4 times a week) can prevent impotence. That is why most impotence cannot be cured, but can be successfully treated.
