Physical causes: About 8 in 10 cases of ED are due to a physical cause. In most cases due to physical causes (apart from injury or after surgery) the ED tends to develop slowly. So, you may have intermittent or partial ED for a while, which may gradually get worse. If the ED is due to a physical cause, you are likely still to have a normal sex drive (libido) apart from if the cause is due to a hormone problem. In some cases, ED causes poor self-esteem, anxiety, and even depression. These reactions to ED can make the problem worse. online pharmacy for levitra buy levitra

Many cases of sexual dysfunction can be corrected by treating the underlying physical or psychological problems. Treatment strategies may include the following: Psychological therapy: Therapy with a trained counselor can help a person address feelings of anxiety, fear, or guilt that may have an impact on sexual function. Erectile dysfunction, heart disease and other vascular diseases: The root cause of the narrowing of the arteries is caused by atheroma. Atheroma is like fatty patches or plaques that develop within the inside lining of arteries. (This is similar to water pipes that get furred up with scale.) Plaques of atheroma may gradually form over a number of years in one or more places in the body, commonly in arteries going to the heart, brain, legs and penis. In time, these can become bigger and cause enough narrowing of one or more of the arteries to cause symptoms and problems. Penile erection is managed by two mechanisms: the reflex erection, which is achieved by directly touching the penile shaft, and 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 the 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. Can Sexual Problems Be Cured? The success of treatment for sexual dysfunction depends on the underlying cause of the problem. The outlook is good for dysfunction that is related to a treatable or reversible physical condition. Mild dysfunction that is related to stress, fear, or anxiety often can be successfully treated with counseling, education, and improved communication between partners. cialis online new zealand cialis online without prescription
