What causes ED?

ED usually has a physical cause, such as disease, injury, or side effects of drugs. Any disorder that causes injury to the nerves or impairs blood flow in the penis has the potential to cause ED.

Because an erection requires a precise sequence of events, ED can occur when any of the events is disrupted. The sequence includes nerve impulses in the brain, spinal column, and area around the penis, and response in muscles, fibrous tissues, veins, and arteries in and near the corpora cavernosa.

Damage to nerves, arteries, smooth muscles, and fibrous tissues, often as a result of disease, is the most common cause of ED. Diseases-such as diabetes, high blood pressure, nerve disease or nerve damage, multiple sclerosis, atherosclerosis, and heart disease-account for the majority of ED cases. Patients should be thoroughly evaluated for these conditions before they begin any form of treatment for ED.

Lifestyle choices that contribute to heart disease and vascular problems also raise the risk of ED. Smoking, drinking alcohol excessively, being overweight, and not exercising are possible causes of ED.

Surgery-especially radical prostate and bladder surgery for cancer-can also injure nerves and arteries near the penis, causing ED. Injury to the penis, spinal cord, prostate, bladder, and pelvis can lead to ED by harming nerves, smooth muscles, arteries, and the fibrous tissues of the corpora cavernosa.

In addition, ED can be a side effect of many common medicines such as blood pressure drugs, antihistamines, antidepressants, tranquilizers, appetite suppressants, and cimetidine, an ulcer drug.

Psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure can also cause ED. Even when ED has a physical cause, psychological factors may make the condition worse.

Hormonal abnormalities, such as low levels of testosterone, are a less frequent cause of ED.

Erectile Dysfunction and ED

Erectile dysfunction is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction, tied closely as it is about ideas of physical well being, can have severe psychological consequences. Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery. The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology.

Erectile Dysfunction Pathophysiology

Penile erection is managed by two different mechanisms. The first one is the reflex erection, which is achieved by directly touching the penile shaft. The second is the psychogenic erection, which is achieved by erotic or emotional stimuli. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. In both conditions, an intact neural system is required for a successful and complete erection. Stimulation of penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems. Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light.

Casting auditions

Casting means selecting the actors, dancers, singers or other talent for a live or recorded performance. It typically involves auditions before a panel that may include the production's producer, director, and choreographer. In the early stages of casting auditions, the performers may present prepared audition pieces such as monologues or songs. Major productions that need to fill many roles may use a casting director and a specialized staff. Casting calls of celebrity performers may follow strictly personal channels; e.g. direct contact with the director. In entertainment, casting auditions are a pre-production process for selecting a cast of actors and other talent for a live or recorded performance.

Since most dance related productions involve both men and women, more often than not, the two will audition together. When performing dance auditions, you must first be confident in your training. You have worked hard to get an audition and you cannot forget what ultimately got you there. Stay focused and confident and you should do well.

What Causes Sexual Problems?

Some illnesses, disabilities, medicines, and surgeries can affect your ability to have and enjoy sex. Problems in your relationship can also affect your ability to enjoy sex.

Arthritis. Joint pain due to arthritis can make sexual contact uncomfortable. Joint replacement surgery and drugs may relieve this pain. Exercise, rest, warm baths, and changing the position or timing of sexual activity can be helpful.

Chronic pain. Any constant pain can interfere with intimacy between older people. Chronic pain does not have to be part of growing older and can often be treated. But, some pain medicines can interfere with sexual function. You should always talk with your doctor if you have unwanted side effects from any medication.

Diabetes. This is one of the illnesses that can cause ED in some men. In most cases, medical treatment can help. Less is known about how diabetes affects sexuality in older women. Women with diabetes are more likely to have vaginal yeast infections, which can cause itching and irritation and make sex uncomfortable or undesirable.

Heart disease. Narrowing and hardening of the arteries can change blood vessels so that blood does not flow freely. As a result, men and women may have problems with orgasms, and men may have trouble with erections. People who have had a heart attack, or their partners, may be afraid that having sex will cause another attack. Sexual activity is often safe. Always follow your doctor’s advice.

Incontinence. Loss of bladder control or leaking of urine is more common as we grow older, especially in women. Extra pressure on the belly during sex can cause loss of urine, which may result in some people avoiding sex. This can be helped by a change in positions. The good news is that incontinence can usually be treated.

Stroke. The ability to have sex is sometimes affected by a stroke. A change in positions or medical devices may help people with ongoing weakness or paralysis to have sex. Some people with paralysis from the waist down are still able to experience orgasm and pleasure.

Dementia. Some people with dementia show increased interest in sex and physical closeness, but they may not be able to judge what is appropriate sexual behavior. Those with severe dementia may not recognize their spouse, but still seek sexual contact. This can be a confusing problem for the spouse. A doctor, nurse, or social worker with training in dementia care may be helpful.
