Definition:

Erectile dysfunction (ED) is a type of male sexual dysfunction when a man is not able to achieve or maintain a firm erection required for satisfactory sexual intercourse.

ED can be classified into three types (depending on how hard it is to obtain or sustain an erection): mild, moderate, and severe. This condition is also known as male impotence.
Symptoms:

Erectile dysfunction is characterized by the frequent failure to get or maintain an erection.

It is normal for a man not to be able to get an erection in some occasions (for example, when being anxious or sad), but if it happens on a regular basis that may indicate having some degree of erectile dysfunction.
Causes:

A full erection requires a healthy nervous system (to properly transmit signals from the brain to the right parts of the body when sexual arousal occurs), and good blood circulation (since blood is what fills the body of the penis and make it erect and hard). And so, there are many different causes of ED, including:

* Physical causes: arterial disorders and blood diseases, brain and nerve disorders, hormonal disorders, heart disease, diabetes, surgery (prostate, bladder, colon, etc), accident and injury.
* Psychological causes: worry, stress, depression and grief. Men who lack confidence in their sexual ability may suffer from ED due to anxiety.
* Lifestyle: Smoking, drinking alcohol, taking drugs, lack of exercise and obesity all can result in impotence. Smoking is one of the lead causes of impotence since it damages blood vessels.

Treatment:

There are numerous conventional and alternative treatments for erectile dysfunction. Some of these treatments are clinically proven, while the effectiveness of other methods remains disputable. Treatment options include the following:

* Prescription medications: Using FDA-approved, oral anti-impotence drugs is the most effective and easiest way to deal with erectile dysfunction. Currently, there are three FDA-authorized drugs used to treat ED: Viagra (sildenafil citrate), Cialis (tadalafil), and Levitra (vardenafil HCl). These medications are only available with a prescription from a doctor, and may not be safe for everyone.
* Penis pumps (aka vacuum pumps): These devices are used to get a temporary erection. They work by creating vacuum around the penis, which forces more blood to flow into the penis and then you trap it using a rubber ring around the base of the penis. There are many disadvantages of this technique, including: it can be painful, it may cause injury, excessive “pumping” may burst your blood vessels and cause permanent damage, not convenient or practical for regular use, and they erection does not feel “natural”.
* Surgery: Surgical treatment may be required in case of severe ED, or when other options fail. The procedure involves implanting the penis with an inflatable device called “penile prosthesis”. The device contains a valve that can be used for inflating or deflating the device with a special fluid, and thus it creates or ends an erection on demand. Not so many people prefer surgery because it is risky and expensive.
* Herbal medicine: Natural and herbal supplements have been used for thousands of years to treat many different conditions and diseases. There are “tons” of “herbal” supplements that claim to be a “natural Viagra”, but the fact is, none of these supplements is clinically proven or medically approved to be effective in treating erectile dysfunction. Additionally, most herbal Viagra pills sold over the Internet are nothing more than scam/rip-off.

Facts:

* Erectile dysfunction is one of the most common sexual dysfunctions in men (Source: WHO).
* About 40% of men in their 40s experience some degree of erectile dysfunction (Source: WHO).
* Erectile dysfunction can affect men of all ages; young and old. While the numbers and percentages of ED patients are higher in older men, many young men all around the world still suffer from this condition.
* There is nothing to be embarrassed about if you have, or you think you have, ED. Just relax and pick the right time to discuss the issue with your physician and partner, and (hopefully) things will start to get simpler from there. The worst thing you can do about it is just sit down and do nothing.

Cutting Viagra Pills

Some pharmacies sell different doses of Viagra pills at the same rate. You can benefit from this and save lots of money on your Viagra purchases.

Most men use Viagra 50 mg because it gives them the best results, but some of them buy Viagra 100 mg instead and then cut the pills into two identical halves, each treated as a 50 mg dose.

You can try cutting high-dosage Viagra pills and see if it works for you. If you get satisfactory results, then you can start saving a lot of money on Viagra

To cut a Viagra pill effectively without crushing the pill you can use a custom made Viagra pill cutter/splitter (see the image below). These devices are not expensive (usually less than $10) and you may even get it for free when you purchase Viagra from some drugstores.

The best Viagra

Every day we are inundated with emails and pop-up adverts about the best Viagra for sale, but these adverts beg the question: Is there anything like ‘The Best Viagra’?

On the basis of the mails we get, what exactly do these online pharmacies mean by their claims to have the best Viagra for sale? Do they mean there are different versions of brand Viagra and all of them have different qualities? Could it be that there is just one brand of Viagra that is superior to the other types of Viagra available in the market?

Whatever the reason for the claim, Viagra tablets are exclusively produced by Pfizer, and this company produces only one version of the little blue tablets, as it is officially known.

So if one is to talk about Viagra in the context of “the Best Viagra” mode, then would be looking at the Viagra produced by Pfizer.

What is Viagra?
Viagra is the first significant oral medication approved by the FDA for the treatment of men who are suffering from a condition known as erectile Dysfunction (ED). The popular ED drug was originally developed as a cardiovascular medicine intended for the improvement of blood flow to the vessels of the heart.

During initial studies, however, the drug was discovered to have a significant side effect. The men who were given the trial tablets began to report a remarkable difference in their ability to attain and sustain an erection.

Further studies were conducted and later completed and on the 27th of March, 1998, the drug gained approval by the FDA for the treatment of the stated condition. Later that year, Viagra gained approval in the European Union and has since been recognised by regulatory authorities in over 100 countries all over the world as an effective treatment of ED.

How does Viagra work?
Viagra tablets are taken orally, approximately 30 minutes to one hour after which they are absorbed in the bloodstream. Inside the body, Viagra tablets exhibit their erectile effect by acting as inhibitors of an enzyme called phosphodiesterase type (PDE5), which is primarily concentrated in the penis.

By inhibiting PDE5, the smooth muscles in the penis are relaxed for a longer period by a series of connected reactions starting with the raised levels of the cyclic guanosine monophosphate. The relaxation of the smooth muscles allows for increased blood flow into the corpus cavernous tissue of the penis thereby enabling an erection.

A unique thing about Viagra tablets is that they enhance a naturally occurring process; therefore, only through sexual stimulation will an erection be possible.

Why is Viagra sometimes referred to as sildenafil citrate?
Sildenafil citrate is the generic name for Viagra. What is meant by “a generic name” of a medication is that the name represents the nonproprietary or chemical name. A brand name, by contrast, is the name a pharmaceutical company assigns to a drug simply for marketing purposes.

What is the appropriate dose?
The standard dose for taking Viagra is 50mg, usually an hour before sexual activity. However, an impotent man who is older than 65 or have a severe liver or kidney condition, would be recommended to start with the lowest dose of 25mg by physicians.

Viagra should be taken once in a 24-hour period and the maximum doses taken in a day should not exceed 100mg.
