An erection works by allowing blood into the spongy tissues of the penis but stopping it from flowing back out again.. Anything affecting the arteries, veins or nerves that supply the penis will influence the ability to have an erection. These can include:
Medicines such as anti-depressants and drugs for high-blood pressure (such as ACE inhibitors and beta-blockers);
Alcohol, smoking, and taking illegal drugs;
Hormonal conditions, such as not having enough testosterone in your body, or having too much of another hormone called prolactin;
Conditions affecting the erectile tissue of the penis, such as prostate cancer;
Serious long-term conditions such as kidney or liver failure.
As you get older, you're more likely to have another condition that causes erection problems, such as heart disease or diabetes. But that doesn't mean you shouldn't seek treatment for your erection problems, as well as the underlying condition.
Some of the most common psychological causes of erectile dysfunction include:
Stress or anxiety,
Relationship or sexual identity issues.
Sometimes an occasional erection problem caused by a minor everyday problem such as a few too many drinks, or a particularly hard day at work, can begin a cycle of worrying. This can turn into a psychological cause of further erectile difficulties.
Treatment depends on the cause. Testosterone supplements may be used for cases with hormonal deficiency. However, usually the cause is lack of adequate penile blood supply as a result of age-dependent damage of inner walls of blood vessels. Previously, medical substances (e.g. apomorphine) were directly injected into the erectile tissue of penile shaft to treat impotence. In some cases refractory to the medical treatment, a penile implant (penile prosthesis) could be advised. After the discovery of orally active agents that increase the efficacy of NO, which dilates the blood vessels of corpora cavernosa, more conservative methods started to be used.
The prescription PDE5 inhibitors sildenafil (Viagra?, vardenafil (Levitra? and tadalafil (Cialis? are prescription drugs which are taken orally. They work by blocking the action of PDE5, which causes cGMP to degrade. cGMP causes the smooth muscle of the arteries in the penis to relax, allowing the corpus cavernosum to fill with blood.This article is the property of www.medical-store.info and this article is written only for educational and information purpose so that our reader can get more knowledge about impotence.
