Prices of Viagra and Cialis

Erectile dysfunction (ED) affects the lives of many middle-aged men and their partners. The term erectile dysfunction covers a range of disorders, but usually refers to the inability to obtain an adequate erection for satisfactory sexual activity. Although erectile dysfunction, formerly called impotence, is more common in men older than 65, it can occur at any age. An occasional episode of erectile dysfunction happens to most men and is normal. As men age, it's also normal to experience changes in erectile function. Erections may take longer to develop, may not be as rigid or may require more direct stimulation to be achieved. Men may also notice that orgasms are less intense, the volume of ejaculate is reduced and recovery time increases between erections. Erectile dysfunction may also be a sign of a physical or emotional problem that requires treatment.

Erectile dysfunction was once a taboo subject, but more men are seeking help. Doctors are gaining a better understanding of what causes erectile dysfunction and are finding new and better treatments.

This Website discusses all about erectile dysfunction, physiology of the normal erection and the pathophysiology, and treatment of ED.

What is Erectile Dysfunction?

Erectile dysfunction or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis for satisfactory sexual intercourse regardless of the capability of ejaculation. There are various underlying causes, such as diabetes, many of which are medically reversible.

The causes may be physiological or psychological viagra price comparison. Psychological impotence can often be helped by almost anything that the patient believes in; there is a very strong placebo effect.

Due to its embarrassing nature and the shame felt by sufferers, the subject was taboo for a long time, and is the subject of many urban legends. Folk remedies have long been advocated, with some being advertised widely since the 1930s. The introduction of perhaps the first pharmacologically effective remedy for impotence, sildenafil (trade name Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories about it and heavy advertising.

The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms.

Signs and symptoms:

Erectile dysfunction is characterized by the inability to maintain erection. Normal erections during sleep and in the early morning suggest a psychogenic cause, while loss of these erections may signify underlying disease, often cardiovascular in origin. Other things leading to erectile dysfunction are diabetes mellitus (causing neuropathy) or hypogonadism (decreased testosterone levels due to disease affecting the testicles or the pituitary gland).

Here are some causes of Erectile Dysfunction:

* Arousal: The first step is sexual arousal, which men obtain from the senses of sight, touch, hearing and smell, and from thoughts about viagra price comparison.

* Nervous system response: The brain communicates the sexual excitation to the body's nervous system, which activates increased blood flow to the penis.

* Blood vessel response:. A relaxing action occurs in the blood vessels that supply the penis, allowing more blood to flow into the shafts that produce the erection.

Physiology of normal erections:

Penile erections involve an integration of complex physiologic processes involving the CNS, peripheral nervous system, and hormonal and vascular systems. Any abnormality involving these systems, whether from medication or disease, has a significant impact on the ability to develop and sustain an erection, ejaculate, and experience orgasm. Tumescence, the vascular filling of the cavernous bodies, relies on neural and hormonal mechanisms operating at various levels of the neural axis. This is unique among visceral functions because it requires central neurological input.

Andersson et al viagra price comparison summarized some of the information related to the pathways involved in erectile function. The degree of contraction of corpus cavernosal smooth muscle determines the functional state of the penis. The balance between contraction and relaxation is controlled by central and peripheral factors that involve many transmitters and transmitter systems. At the cellular level, smooth muscle relaxation occurs following the release of acetylcholine from the parasympathetic nerves.

Pathophysiology of erectile dysfunction:

Erectile Dysfunction is essentially a vascular disease. It is often associated with other vascular diseases and viagra price comparison conditions such as diabetes, hypertension, and coronary artery disease. Other conditions associated with Erectile Dysfunction include neurologic disorders, endocrinopathies, benign prostatic hyperplasia, viagra price comparison, and depression. Conditions associated with reduced nerve and endothelium function, such as aging, hypertension, smoking, hypercholesterolemia, and diabetes, alter the balance between contraction and relaxation factors. These conditions cause circulatory and structural changes in penile tissues, resulting in arterial insufficiency and defective smooth muscle relaxation. In some patients, sexual dysfunction may be the presenting symptom of these disorders.

Treatment:

Sildenafil Citrate is the way to treat Erectile Dysfunction. Generic Viagra contains sildenafil citrate and contains same ingredients like branded drug.

A Peep into the Trademark Name of Viagra

Author: Tracy Whitney

Article source: http://www.goarticles.com/. Used with author's permission.

'Viagra' had become a hero much earlier than its launch. Thanks to the media and its makers. Viagra had been publicized as that one magic wand which could improve a man's sexual health caused because of his impotency or to say according to the medical term prevalent--erectile dysfunction. Every where people could be heard talking about the so called forthcoming magical effects of Viagra much earlier than its launch itself, scattered discussions on Viagra news, countless Viagra jokes and what not!

But have you ever thought that how did Viagra get its much publicized name—'Viagra?' Whose brain child this brand name was? There had been continuous speculation since then. Was it named as Viagra because of its proximity to the word 'Vigor' meaning strength? Many even guessed that may be it was named as 'Viagra' because of its close phonetic sonance to the famous waterfall 'Niagara' epitomizing flow, power and grandeur.

The reality is the reason of naming this anti -impotence drug 'Viagra' is much more banal or uneventful.

The name 'Viagra' was finalized because of its being inoffensive in nature. This word was not in use in English or for that matter in any other foreign language to convey a particular meaning and that is why it was such that it could not cause any embarrassment or confusion to any body for the purpose that it was made for.

Definitely, the credit for publicizing this much famous name 'Viagra' goes to the official makers of this drug. It is a well known fact that just as mostly all the pharmaceutical companies work in consultation with their researchers and consultants similarly the makers of Viagra also work in close coordination with their consultants who work on the potential drug names and later trademark them. Later these names are stored in the trademark drug names databank. When a new drug needs a brand name then all the drug names are considered as a potential candidate for the branding of the new drug.

Every new drug name has to satisfy a long list of criteria. For e.g. it has to be simple so that people find it easy to pronounce, it should be simple enough to be memorized by the people and most importantly it should not bear any particular or unusual meaning in any language. After this the name goes to a series of linguistic screens to check that it does not carry any special meaning in any of the foreign languages and legal as well as trademark screens to check that nobody else is using that particular name. Similarly the researchers of the official makers of Viagra also tested the potential name 'Viagra' in different patterns to check that it does not have any unusual meaning and is not used by anybody else in the world.

So this is how the sojourn of Viagra started in the year 1998 with its launch and ever since then Viagra has never looked back and is persistently proceeding on its journey of fame as one of the first oral pill for men to treat erectile dysfunction.
