Erectile dysfunction
Due to the sensitive nature of the condition, it is difficult to estimate how many men it affects.
However, it is believed about 5% of 40-year-old men and up to 25% of 65-year-old men may have the condition.
How does an erection occur?
The penis contains two chambers full of spongy tissue called the corpora cavernosa.
When a man becomes sexually aroused impulses from the brain and local nerves cause muscles in the corpora cavernosa to relax, allowing blood to flow in and fill the spaces within the tissue.
This creates pressure in the corpora cavernosa, making the penis expand.
A membrane called the tunica albuginea helps trap the blood in the corpora cavernosa, thereby sustaining erection.
The erection is lost when the muscles contract to stop blood flowing into the penis, and open outflow channels.
What causes erectile dysfunction?
A successful, sustained erection requires a sequence of events to occur in a precise fashion.
Anything which disrupts this sequence can lead to problems either getting, or keeping an erection.
The most common cause of erectile dysfunction is damage to the tissues, either the nerves, arteries, muscles or fibrous tissue.
This is often linked either to disease. Conditions such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis and cardiovascular disease account for around 70% of cases of erectile dsyfunction.
In some cases the condition is caused by damage to the nerves and arteries near the penis which can occur during surgery, particularly for prostate and bladder cancer.
Physical injury to the penis, spinal cord, prostate, bladder or pelvis can also be a factor.
Erectile dsyfunction is also a side effect of some common medications, including blood pressure drugs, exercise for erectile dysfunction remedy
, antidepressants and ed tablets
.
Experts believe that psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure cause up to 20% of cases.
Smoking, which affects blood flow, has also been linked to the condition.
Can it be treated?
Yes. There is a range of ways to treat erectile dysfunction.
Doctors will consider psychotherapy for patients who are likely to benefit, but alternatives include drugs, vacuum devices, and surgery.
Drug Therapy:
One drug in particular, Viagra (Sildenafil Citrate), has become an international phenomenon since its launch in the late 1990s.
The drug, also known as Sildenafil, does not directly give a man an erection. It works by boosting the natural mechanism that leads to an erection.
When a man is sexually aroused, certain tissues in his penis relax. This allows large amounts of blood to flow into the muscle, thus producing an erection. Viagra helps by elevating the levels of the chemical that causes the tissues to relax.
These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers.
In a small number of cases, people who have taken Viagra have complained of headaches, flushing and erectile dysfunction new drugs
.
It can also cause some visual problems, including an increased sensitivity to light, blurred vision or an inability to tell the difference between blue and green. Men who are already taking medicines that contain nitrates, such as nitro-glycerine, are strongly advised not to use Viagra because the combination can lower blood pressure too much.
Another drug, Levitra (Vardenafil), works first time for nearly nine out of 10 men (87%) who are experiencing erection difficulties.
Penile injections:
The injection of drugs directly into the tissues of the penis to trigger an erection was more common before the advent of new drugs such as Viagra.
The drugs relax muscles and increase blood flow to create an erection.
Vacuum Devices:
These work by creating a partial vacuum around the penis, which draws blood into the organ.
The devices have three components: a plastic cylinder, into which the penis is placed; a pump, which draws air out of the cylinder; and an elastic band, which is placed around the base of the penis to maintain the erection after the cylinder is removed and during intercourse.
Surgery:
There are different types of surgery:
Implanted devices, known as prostheses, can restore erection in many men.
These can come in different forms. For instance, paired rods can be inserted into the corpora cavernosa to enable the user to manually adjust the position of the penis.
Alternatively, inflatable cylinders can be inserted inside the penis and expanded using pressurized fluid.
In some cases doctors may attempt to repair blockages in damaged arteries. However, this usually only works if the blockages are not widespread.
It is also possible to tie off veins to reduce the leakage of blood that can reduce the rigidity of an erection. However, experts have raised questions about the long-term effectiveness of this procedure, and it is rarely done.

Consumers Beware Of The Internet: Americas Watchdog Declares War on Counterfeit Drug & Counterfeit Cigarette …
|
After a two year investigation into the murky world of on line pharmacies and Internet “cheap cigarettes”, Americas Watchdog and its Global Piracy & Counterfeiting Consultants have a worldwide recommendation to all consumers. This can be summed up in three words: “Don't Do It”. The investigation concluded that the “on line drugs and cigarettes could be lethal or you could get charged for something you never get”. By doing business with a on line cigarette or drug “retailer”, a consumer may have just given their credit information to the Russian Mafia or organized crime. (PRWEB) May 21, 2007 — Americas Watchdog is one of the premier consumer advocacy groups in the United States. The group has formed a piracy & sildenafil citrate and discount task force to take on sellers of “on line” counterfeit drugs or cigarettes. The group is warning all consumers worldwide to avoid doing business with “on line” pharmacies or cigarette “retailers” unless they can provide credentials. Aside from potential lethal counterfeit drugs or cigarettes, consumers expose them selves to possible identity theft or paying for something they never get. “Who wants to do business with the Russian Mafia or organized crime”? Americas Watchdog's Global Piracy & Counterfeiting Consultants are seeking corporate partnerships to curb this growing worldwide problem with buy operations designed to expose the counterfeiters or their “retail” outlets. The two areas to be targeted are: *Counterfeit Cigarettes The cigarette industry, like many other industries, faces an unprecedented challenge from counterfeit products. The WCO estimates that 190 billion counterfeit cigarettes are produced each year in China, making it “a major source country for European/US markets”. Americas Watchdog and its Global Piracy & Counterfeit Consultants warn that counterfeit cigarettes, which may look identical to those purchased legitimately over the counter, can contain hazardous levels of damaging toxins, including arsenic. The black-market cigarettes have higher levels of tar, nicotine and carcinogenic chemicals from contaminated tobacco leaves. In other words, counterfeit cigarettes could be dangerous. Americas Watchdog and its Global Piracy & Counterfeiting Consultants are warning consumers not to purchase counterfeit cigarettes or “on line cigarettes” as they could be a serious health hazard. In addition by purchasing counterfeit cigarettes a consumer may actually be enriching terrorists or organized crime. Americas Watchdog would welcome the opportunity to work directly with British Tobacco, the Altria Group, Reynolds American, Altadis or other cigarette manufacturers in order to curb and or disrupt the manufacturing or distribution of counterfeit cigarettes. *Counterfeit Drugs ” /> Lipitor, Diovan, Actonel, Nexium, Hyzaar, Ezetrol (known as Zetia in the United States), Crestor, Celebrex, Arimidex and Propecia. All of these medications require a prescription from a licensed health care provider to be legally dispensed. DRUG NAME LIPITOR CRESTOR ZETIA (US name) / EZETROL (Canadian name) DIOVAN HYZAAR ACTONEL NEXIUM CELEBREX ARIMIDEX PROPECIA According to the FDA, drug counterfeiters defraud consumers by selling products that resemble legitimate drugs but may contain inactive or incorrect ingredients; contain improper doses of active ingredients; or be otherwise contaminated. Purchasing ED products on line from illegitimate websites involve risks such as:: — Fake or “generic” ED drugs may be manufactured in unregulated factories, often in regions of the world that do not share the same rigorous standards for bayer levitra patent — The drugs may contain dangerous additives — The illegal drugs may not work as claimed, or at all — Illegitimate pharmacies may take payment but not ship ordered products, or shipped products may be seized by the U.S. government because they are illegal — Web sites that distribute counterfeit ED pills, including “generic Viagra”, Cialis and Levitra have been found to abuse credit card information. Americas Watchdog and its Global Piracy & Counterfeiting Consultants (Http://GP-CC.Com ) strongly encourage consumers in the US and worldwide to stay away from Internet cigarette “retailers”, Internet pharmacies or computer pop ups for ED or other medical conditions. According to Americas Watchdog's President, “these counterfeit drugs could actually kill you. If a consumer wants to be safe, consult a physician or a licensed pharmacy, rather than trusting someone you don't know anything about on the Internet.” As a part of one of their investigations, Americas Watchdog ordered a sedative from an “on line pharmacy”, and they were sent a blood thinner instead. Americas Watchdog wants to shut down all illegal Internet pharmacies and assist in the prosecution of illegal “on line pharmacies” or counterfeit drug manufacturers and counterfeit cigarette manufactures or “retailers”.
