Cialis online uk Erectile Dysfunction (Impotence) - Erectile dysfunction (ED) means that you cannot get a proper erection. There are various causes. However, most cases are due to narrowing of the arteries that take blood to the penis. This is due to a build up of atheroma in these arteries. This is similar to the way the heart arteries are affected in people with heart disease. As with heart disease, smoking and heavy alcohol drinking are important risk factors. There are various other causes of ED listed below. Most cases of ED can be treated. The common treatment is to take a tablet before you plan to have sex. There are also various other treatment options. If you have ED, you may also be advised on lifestyle factors and treatments to minimise your risk of developing heart disease. What are the side effects of vardenafil (Levitra)? Vardenafil is generally well tolerated with only mild side effects. These side effects include headache, flushing, nasal congestion, dyspepsia, body aches, dizziness, nausea, and increased blood levels of the muscle enzyme creatine kinase. viagra online quality best
What is normal penis anatomy? The penis contains two chambers, called the corpora cavernosa, which run the length of the upper side of the penis (see figure 1 below). The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa. Filling the corpora cavernosa is a spongy tissue consisting of smooth muscles, fibrous tissues, spaces, veins, and arteries. A membrane, called the tunica albuginea, surrounds the corpora cavernosa. Veins located in the tunica albuginea drain blood out of the penis. Sildenafil has been found to be well tolerated without important side effects. The reported side effects are usually mild and include headache, flushing, nasal congestion, nausea, dyspepsia, (stomach discomfort), diarrhea, and abnormal vision (seeing a bluish hue or brightness). Phosphodiesterase type 5 inhibitors - The cyclic nucleotide phosphodiesterases constitute a group of enzymes that catalyze the hydrolysis of the cyclic nucleotides cyclic AMP and cyclic GMP. They exist in different molecular forms and are unevenly distributed throughout the body.

Hypertension (high blood pressure): People with essential hypertension or arteriosclerosis have an increased risk of developing erectile dysfunction. Essential hypertension is the most common form of hypertension; it is called essential hypertension because it is not caused by another disease (for example, by kidney disease). It is not clearly known how essential hypertension causes erectile dysfunction; however, those with essential hypertension have been found to have low production of nitric oxide by the arteries of the body, including the arteries in the penis. High blood pressure also accelerates the progression of atherosclerosis, which in turn can contribute to erectile dysfunction. Scientists now suspect that the decreased levels of nitric oxide in patients with essential hypertension may contribute to erectile dysfunction.

Call Your Doctor immediately or Go to an Emergency Room If: You have an extended or painful erection, unrelated to sexual desire, lasting more than a few hours. Erectile dysfunction, heart disease and other vascular diseases: Although ED can be caused by various conditions, about 7 in 10 cases are due to narrowing of the small arteries in the penis. This causes reduced blood flow to the penis. This is the same problem that can occur in other blood vessels. For example, narrowing of the blood vessels in the heart (the coronary arteries) is a cause of angina and other heart problems. Narrowing of blood vessels to the brain is a risk factor for having a stroke. Narrowing of blood vessels in the legs can cause peripheral vascular disease. Who should not use tadalafil (Cialis)? Tadalafil can cause hypotension (abnormally low blood pressure, which can lead to fainting and even shock) when given to patients who are taking nitrates. Patients taking nitrates daily should not take tadalafil. Most commonly used nitrates are medications to relieve angina (chest pain due to insufficient blood supply to heart muscle because of narrowing of the coronary arteries). These include nitroglycerine tablets, patches, ointments, sprays, pastes, and isosorbide dinitrate and isosorbide mononitrate. Other nitrates such as amyl nitrate and butyl nitrate are found in some recreational drugs called "poppers."
