What causes ED in men?
Erectile dysfunction is a condition that affects men. It is characterized by an inability of the male to successfully have an erection. For a long time researchers and medical experts were unclear as to what was responsible for male impotency. Many were convinced that the condition of erectile dysfunction was one caused primarily by psychological factors.

Simply put, the man’s impotency was simply locked up in his head. Although recent events have revealed that this indeed is one of the factors responsible for impotency, it only accounts for less than 30% of the recorded cases.

Instead, most of the men who are diagnosed with erectile dysfunction are found to suffer from physically induced symptoms. There are many reasons why this might occur but men who suffer physically induced impotency find that their body is unable to deliver adequate blood flow to the male organ.

The effect of an erection in a man is triggered by the absorption of blood by tissues located within the penis.. As this tissue absorbs the inflow of blood, it becomes bigger and gains in mass.

It remains this way until ejaculation, at which point the vein responsible for the outflow of blood releases its constricted stance and allows the held blood to flow out of the penile area.

However, for men who are suffering from physical impotence, the inflow of blood which is required for the inflation of this penile tissue does not occur. This might be as a result of insufficient pressure from the heart or weak arteries which are unable to support the required flow of blood.

The treatment of this kind of impotency is achieved with Viagra pills. Viagra tablets are also referred to as PDE-5 inhibitors. As a result of their actions many of the blood vessels in the body—in this case the penile arteries are able to relax and allow an increase flow of blood into the penis.

The arteries remain in this state for as long as the effects of Viagra are found to last. This is normally found to be at least 4 hours.

There are many conditions that have been shown to be responsible for this form of impotency. For instance, cardiac conditions, Multiple sclerosis and diabetes can result in a weakened flow of blood in the system, Popular lifestyle habits such as drinking and smoking also contribute towards the degeneration of the arteries.

For all these conditions and more, the symptom of erectile dysfunction can be treated by using anti impotence pills like Viagra.

Viagra tablets are produced by the pharmaceutical company Pfizer. Since its release 10 years ago, more than a billion Viagra tablets have been sold. One of the reasons behind its huge popularity can be traced to the efficiency of the tablet.

Sold in dosages of 25mg, 50mg and a 100mg Viagra tablets have proven to be successful in more than 80% of the cases treated.

Taking of Viagra pills, just like every other drug, can sometimes result in negative side effects. These is as a result of the increased flow of blood in the body.

Some of these side effects include stomach aches and headaches. It is important when buying Viagra pills to ensure that you only buy original Viagra tablets. Viagra pills are available online.

The release of Viagra pills into the market came with the announcement that the discovery of the magic drug was serendipitous. The drug only became marketed as an anti-impotence drug after it was discovered that the men who were given the little blue pills to take home as part of clinical trials for a newly developed drug that was intended to be used for the treatment of Angina pectoris and pulmonary arterial hypertension produced a surprising, albeit welcome, side effects.

When the men refused to return the pills they were given, the pharmaceutical chemists who worked on the new formulation started asking questions, and it was soon found out that the reason why the men had refused to return the drug was because the drug had made the men attain erection, a scenario which was quiet alien to them prior to using Viagra tablets.

Fast forward more than ten years later, history is about to repeat itself, it seems.

A new drug – Flibanserin – has been developed in similar circumstances, but among women this time around.

Produced by the German drug maker Boehringer Ingelheim, Flibanserin (BIMT-17) is a drug that is currently being investigated as a drug for women who are experiencing a decrease in their sexual desire.

The German company had been simply trying to develop a fast-acting antidepressant, one that patients would respond to in a matter of days, not weeks as in most current treatments and hadn’t set out to produce a Viagra-like drug for women.

However, Boehringer Ingelheim reported on November 16, 2009, that late-stage trials for the Viagra-like drug showed that the drug enhanced sexual desire and increased the number of “satisfying sexual events” in women whose libidos were abnormally low.

The results of four Phase III studies involving over 2,000 woman who were in pre-menopausal stage and who were suffering from a type of disorder known as Hypoactive Sexual Desire Disorder (HSDD) were presented at the congress of the European Society for Sexual Medicine in France.

According to women who use the drug, the average number of times they experienced “satisfying sexual events” increased from 2.8 to 4.5 times a month. Women who used the placebo, however, said the number of times they experienced such satisfying sexual events increased to 3.7 times a month.

Unlike Viagra pills, Flibanserin must be taken once daily and could take up to a month before it can start to produce its effect.

Flibanserin increases dopamine and noradrenalin and decreases serotonin in animals.

Mechanism of action
Flibanserin helps to enhance female libido by directly manipulating the chain of chemical reactions in the brain that are believed to be responsible for triggering sexual desire.

This is quite different from Procter & Gamble’s hormone patch Intrinsa, which is aimed at helping women in their post-menopausal stage.

Clinical trials
As of November 2009, Phase III clinical trials are ongoing. The aim of these trials is to assess the safety and efficiency of the drug in pre- and post-menopausal women.

If this groundbreaking drug is passed safe and efficient for the treatment of sexual dysfunctions in women, it would be a major breakthrough in this widely unknown field.

When men talk of the misery behind aging, their views are normally found centred on the same ills. The onset of aches, the stiffness in their joints and the dreaded possibility of impotency. In many instance, the odds seem to indicate that the development of erectile dysfunction is almost a certainty.

Too many factors exist which can result in its development. For instance, many people experience hypertension as they age past 60. Considering more than half of the men who are diagnosed with hypertension ultimately develop erectile dysfunction the odds are an uncomfortable probability.

Another age related condition that has been found to contribute to impotency is diabetes and multiple sclerosis. The former affects the blood flow rate and function whilst the second attacks the nerves and sensory features. Both of these conditions if left untreated are also common factors of impotency.

One of the events that occur with aging is a weakening of our system. A man at the age of 50 is less likely to run a marathon at the same pace which he did when he was 30.

Men lose muscle mass and their bones become more brittle. Of more importance however is the condition of their hearts. The heart rate of men becomes slower the older they get. In some severe cases, a lifestyle of unhealthy living can cause the onset of cardiac functions.

It is no closed secret that an erection—and subsequent actions of sex—require the function of an efficient heart. For an erection to occur there has to be an increase of blood flow going into the penile areas. This is achieved by the quickening of a man’s pulse rate.

Men who do have weaker hearts are therefore most times unable to develop an erection.

But erectile dysfunction is not always caused by the transition of the body into old age; it is also caused by actions which are done in the early lives of most men. For instance, a lifestyle of drinking and smoking will only result in serious consequences.

Men who drink regularly are found to develop ED much earlier than men who do not. In many cases, men who practice a life style of heavy drinking are found to already possess signs of ED whilst still in their 50s. The same rule is found amongst people who smoke.

The actions of tobacco in their blood stream causes their arteries and blood vessels to stiffen more rapidly than they naturally should. This in turn causes a weakened flow of blood when an erection is required.

Fortunately almost all of these cases are easily treated with the use of Viagra tablets. Viagra tablets are produced by the company Pfizer. They are available in varying doses. For men who are above the age of 60, it is often advised that they seek the counsel and opinion of their doctors before embarking on the use of Viagra.

In most instances, men found in this age demographic are restricted to the use of 25mg pills.

However, this does not mean that ED only affects older men. Cases of this nature has also been known to occur amongst men in their early 20s and 30s.
