DIAGNOSIS OF ERECTILE DYSFUNTION PROLARGENT5X5 EXTREME

  DIAGNOSIS OF ERECTILE DYSFUNTION

There are no formal tests to diagnose erectile dysfunction. A useful and simple way to distinguish between physiological and psychological impotence is to determine whether the patient ever has an erection. If never, the problem is likely to be physiological; if sometimes (however rarely), it could be physiological or psychological. The current diagnostic and statistical manual of mental diseases  has included a listing for impotence.

Duplex ultrasound

Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. Ultrasound is then used to see vascular dilation and measure penile blood pressure.

Penile nerves function

Tests such as the bulbocavernosus reflex test are used to determine if there is sufficient nerve sensation in the penis. The physician squeezes the glans (head) of the penis, which immediately causes the anus to contract if nerve function is normal. A physician measures the latency between squeeze and contraction by observing the anal sphincter or by feeling it with a gloved finger inserted past the anus.

Nocturnal penile tumescence (NPT)

 It is normal for a man to have five to six erections during sleep, especially during rapid eye movement (REM). Their absence may indicate a problem with nerve function or blood supply in the penis. There are two methods for measuring changes in penile rigidity and circumference during nocturnal erection: snap gauge and strain gauge. A significant proportion of men who have no sexual dysfunction nonetheless do not have regular nocturnal erections.

Penile biothesiometry

This test uses electromagnetic vibration to evaluate sensitivity and nerve function in the glans and shaft of the penis.

Dynamic infusion cavernosometry (DICC)

technique in which fluid is pumped into the penis at a known rate and pressure. It gives a measurement of the vascular pressure in the corpus cavernosum during an erection.

Corpus cavernosometry

Cavernosography measurement of the vascular pressure in the corpus cavernosum. Saline is infused under pressure into the corpus cavernosum with a butterfly needle, and the flow rate needed to maintain an erection indicates the degree of venous leakage. The leaking veins responsible may be visualised by infusing a mixture of saline and x ray contrast medium and performing a cavernosogram.;[19] Digital Subtraction Angiography: In DSA, the images are acquired digitally.

Magnetic resonance angiography (MRA)

This is similar to magnetic resonance imaging. Magnetic resonance angiography uses magnetic fields and radio waves to provide detailed images of the blood vessels. Doctors may inject a "contrast agent" into the patient's bloodstream that causes vascular tissues to stand out against other tissues. The contrast agent provides for enhanced information regarding blood supply and vascular anomalies.

Erectile Dysfunction

Erectile Dysfunction May Signal Heart Disease

TUESDAY, Jan. 29 (HealthDay News) -- Doctors should look more closely at the overall health of impotent men, a large new study suggests.

Men with even mild erectile dysfunction -- but no known heart problems -- face a major extra risk of developing cardiovascular conditions in the future. And as erectile dysfunction becomes more pronounced, signs of hidden heart disease and earlier death risk grow.

Not surprisingly, men already known to have a heart condition along with severe erectile dysfunction fare worst of all, the Australian researchers found.

Among men aged 45 and up without diagnosed heart disease, those with moderate or severe erectile dysfunction were up to 50 percent more likely to be hospitalized for heart problems, according to an adjusted analysis. Erectile dysfunction boosted the risk for hospitalization even more when men had a history of cardiovascular disease.

Erectile problems, which become more likely as men grow older, aren't a guarantee of heart problems. Still, men with erectile dysfunction should "take action by seeing a health professional and asking for a heart check," said study lead author Dr. Emily Banks. "Men with erectile dysfunction need to be assessed for their future risk of cardiovascular disease, and any identified risk must be managed appropriately."

Banks is a professor of epidemiology at the Australian National University's National Center for Epidemiology and Population Health.

Banks said an estimated 60 percent of men aged 70 and up suffer from moderate to severe erectile dysfunction. The condition can place major limits on sexual activity and require the use of drugs like Viagra that can come with side effects and awkward challenges when it comes to the timing of doses.

A variety of causes can contribute to impotence, but "it is widely acknowledged that erectile dysfunction is predominantly the result of underlying cardiovascular disease," Banks said.

Doctors already believe that erectile dysfunction is an early warning sign of heart problems, but it's not clear why. It's possible, Banks said, that the arteries of thepenis are smaller than those of other parts of the body and may be more likely to reveal problems when their lining deteriorates.

The new study aims to gain more insight into how the severity of erectile dysfunction translates into a higher risk of cardiovascular disease. The researchers tracked more than 95,000 men aged 45 and up, and compared data collected between 2006 and 2009 to data collected in 2010.

The researchers adjusted their statistics so they wouldn't be thrown off by factors like high or low numbers of men who smoked or drank alcohol, or were wealthy or poor. They found that the men with severe erectile dysfunction, compared to those with no problem, were eight times more likely to have heart failure, 60 percent more likely to have heart disease and almost twice as likely to die of any cause.

Low Testosterone and Sex Drive

Testosterone isn't the only fuel for a man's sex drive and performance. But low testosterone can reduce your ability to have satisfying sex. Lack of sex drive and erectile dysfunction are sexual problems that can result from low testosterone. If low testosterone is the cause, treating it can help.

Researchers haven't unraveled the mystery of just how testosterone increases libido. It's normal for a man's sex drive to slowly decline from its peak in his teens and 20s, but libido varies widely between men. What one man might consider a low sex drive, another might not. Also, sex drive changes within each man over time and is affected by stress, sleep, and opportunities for sex. For these reasons, defining what's a "normal" sex drive is next to impossible. Usually, the man himself identifies a lack of sex drive as a problem. Other times, his partner may consider it to be an issue.  

Low testosterone symptoms don't always include feeling like you have no sex drive. Some men maintain sexual desire at relatively low testosterone levels. For other men, libido may lag even with normal testosterone levels. Low testosterone is one of the possible causes of low libido, however. If testosterone is lowered far enough, virtually all men will experience some decline in sex drive.

In a large study of men in Massachusetts, about 11% overall said they had a lack of sex drive. The researchers then tested all the men's testosterone levels. About 28% of men with low testosterone had low libido. These men were relatively young, with an average age of 47; older men might have worse sexual symptoms.

Low testosterone is only one of the causes of low libido. Stress, sleep deprivation, depression, and chronic medical illnesses can also sap a man's sex drive.

Low Testosterone and Erectile Dysfunction

Surprisingly, low testosterone by itself rarely causes erectile dysfunction, or ED. Low testosterone alone -- with no other health problems -- accounts for a small minority of men with erectile dysfunction. 

Erection problems are usually caused by atherosclerosis -- hardening of the arteries. If damaged, the tiny blood vessels supplying the penis can no longer dilate to bring in the strong flow needed for a firm erection. Diabetes, high blood pressure, and high cholesterol are the three main causes of atherosclerosis and erectile dysfunction.

• ·         Metabolic syndrome

• ·         Obesity

• ·         Endothelial dysfunction

• ·         Diabetes

At the same time, low testosterone is a frequent accomplice to atherosclerosis in creating erectile dysfunction. In studies, as many as one in three men mentioning ED to their doctor have low testosterone. Experts believe that in men with other factors causing erectile dysfunction, low testosterone can strongly contribute, making a difficult situation even worse.

Strengthening the connection, low testosterone is linked in some way with many of the conditions that lead to erectile dysfunction:

Although low testosterone isn't known to cause them, the associations between other medical conditions and low testosterone can be significant.

Testosterone therapy improves sex drive and satisfaction with sex in many men. However, the long-term risks and benefits of testosterone replacement are unknown. Research trials on testosterone replacement in men are ongoing, although results are years away.
