Impotence - impaired ability to achieve an erection

Erectile dysfunction is the inability to achieve and maintain an erection to enable satisfactory sexual activity. Most commonly, orgasm is experienced in conjunction with erection and ejaculation. But it can also be experienced without.

Half of all men between the ages of 40 and 70 experience some form of erectile dysfunction. At a young age, the problems are more severe and increase with age.

A man with erectile dysfunction experiences this as very negative and feelings of inadequacy, anxiety, depression, anger and frustration are common. The man's problems also affect his partner.
The causes of erectile dysfunction are 80% somatic and the remaining 20% psychological disorders.

There are also drugs that can cause erectile dysfunction and these include antihypertensives such as non-selective beta-blockers and diuretics, antidepressants, antipsychotics, cholesterol-lowering drugs, narcotics and painkillers such as opiates and NSAIDs.

Orgasm and ejaculation disorders.
Early ejaculation.
Also known as premature ejaculation, premature ejaculation means that the man is unable to control his ejaculation which comes after a very short period of time after the start of sexual activity. The man also experiences a poorer quality orgasm experience and interpersonal and personal distress over this.

The cause is unknown but it has been shown that psychological and interpersonal factors are associated with the condition, for example, there are reports of men experiencing relationship problems and often experience anxiety in relation to sexual life.

Hypersexual disorder.
An increasing number of patients describe a difficulty in managing their sexual acts. They have sexual fantasies and devote considerable time to sexual activity. This affects their daily life as caregivers. However, it is not the sexual behavior that is the problem, but the extent and difficulty in controlling or reducing the frequency of the sexual behavior. Negative consequences include STDs, unwanted pregnancies, genital damage, guilt, social shame, low self-esteem, relationship, work and financial difficulties. People with this problem describe that they may take risks where they or others may be subjected to coercion and violence that can lead to pain and physical harm.
