Erectile dysfunction is commonly known as erectile dysfunction, erectile dysfunction, erectile dysfunction or impotence. In reality, this is not accurate. These terms are sometimes used to describe other disorders, or to generalise several disorders that are not necessarily related to each other - erectile dysfunction, such as erectile dysfunction or premature ejaculation, on the one hand, and infertility, i.e. the inability to have children, on the other.

How common is erectile dysfunction?

Erectile dysfunction is more common with age. Erectile dysfunction affects almost one in ten men aged 40-49 and one in three men aged 60-69. This was shown in a study conducted by the University of Cologne in 2000. Many other studies in many other countries have found similar results. Experts suspect that there are many unreported cases. So the true number may be higher.

Causes: how do erectile dysfunction occur? 

Erectile dysfunction can be linked to physical and psychological factors. If men suffer from physical potency problems, this can easily lead to additional psychological problems.Purely psychological causes are most common in younger men. In addition to conflicts in the partnership, stress, problems or anxiety disorders, depression is very often associated with erectile dysfunction.

• Circulatory disorders

The most common problems are impaired blood flow to the penis and/or problems with the penile muscles themselves, which are very similar to the muscles in the walls of blood vessels. Or not enough blood flows into the penis because the arteries that feed it are 'calcified' (arteriosclerosis). Or the blood is draining too fast through the veins. Or both. Either way, the amount of blood in the penile erectile tissue is no longer enough for a satisfactory erection.Various diseases that contribute to circulatory problems also increase the risk of erectile dysfunction:    • Diabetes mellitus    • high blood pressure    • Disorders of lipid metabolism

• Testosterone deficiency 

Adequate levels of the male sex hormone testosterone are an important prerequisite for satisfactory erections. With age, the level of testosterone in men's blood usually decreases. Testosterone deficiency (hypogonadism) does not, but can cause erection problems. Therefore, low testosterone levels should be considered as a possible cause (see section "Therapy").

 • Side effects of medicines

Medicines can cause erectile problems as a side effect, including beta-blockers for high blood pressure, dehydrating medicines, lipid-lowering medicines or medicines for depression. Patients should consult their doctor if the package leaflet contains a relevant note and there is a suspicion that the medicine may cause erectile dysfunction. Another preparation may be prescribed. Warning: Do not discontinue or change medication at your own discretion!

 • Other causes

For an erection to occur, it is not only the blood flow to the penis that must be correct. All the nerve pathways involved - from the penis to the spinal cord and brain - must also be intact.Disc herniation, trauma, radiation or surgery in the pelvic area or spinal cord can cause erectile dysfunction. Diseases that can damage peripheral nerves (neuropathy), such as diabetes (diabetes mellitus) or chronic alcohol abuse.Other possible causes of erectile dysfunction are diseases affecting the central nervous system: for example, multiple sclerosis , Parkinson's disease , Alzheimer's dementia or stroke.

Treatment for Erectile Dysfunction:

To treat erectile dysfunction, doctors usually prescribe sildenafil citrate (sold as Viagra or Kamagra). Kamagra is effective medicine for the treatment of declining sexual performance.It works by increasing the blood flow to the penis following by sexual stimulation. Sildenafil allows men to keep an erection hard enough for sexual intercourse.Kamagra is mostly available at online pharmacies. Sildenafil is no longer available without a prescription due to regulatory changes. To be on the safe side, though, you should consult with a doctor or pharmacist to check that it is safe for you to ingest.
