Some facts about ED
 
The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology.    


Erectile dysfunction -ranging from complete inability to maintain erection to inadequate length of the erection - affects millions of men all over the world. Alone in the United States thirty million men suffer from erectile dysfunction. Richard E. Spark, M.D, Associate Clinical Professor of Medicine at Harvard Medical School, says  this number is actually an underestimation of how many men suffer from impaired sexual potency. 

Research indicates that erectile dysfunction is common, and it is suggested that approximately 40% of males suffer from erectile dysfunction or impotence, at least occasionally. As many as 50 percent of men over 40 have been dealing with erectile dysfunction occasionally.    
  


Erectile dysfunction is generally thought of as a condition only affecting older men, but a new study shows just how many young men may also have ED. The study, published in The Journal of Sexual Medicine, shows that one in four men at an outpatient clinic who sought help for erectile dysfunction was actually under the age of 40. Plus, nearly half of those men under age 40 — 48.8 percent of them — had a severe case of the sexual condition, compared with 40 percent of men older than age 40.    

According to Ronald W. Lewis, a study in Chinese men showed that sharing a bedroom with another non-spouse was a predictor of sexual dysfunction in the husbands.    

In the same study, published in the Asian Journal of Andrology, he says, that the prevalence rates for ED in Chinese men were 18.9% in 20- to 29-year olds, 10.4% in 30- to 39-year olds and 16.7% in 40- to 45-years olds. And that the prevalence rate for ED in Brazil was 15%, Italy 17.2%, Japan 34.5% and Malaysia 22.4%.    

In another study published in the Asian Journal of Andrology, Christopher CK Ho, Praveen Singam, Goh Eng Hong and Zulkifli MD Zainuddin are stating, that the rates for ED in Malaysia is 26.8–69%, in Mainland China 38.3%, in Taiwan, China 9-17.7%, in Hong Kong, China 63.6%, in Korea 32.2%, in Thailand 37.5% and in Singapore 51.3–73%.  

In Israel, studies have shown that recently-married religious men may experience impotence owing to the guilt men have at experiencing erectile activity before marriage.  

2.3 million men in Britain suffer from ED but only about 10 percent are treated for the problem.  

The survey of 1.000 men in Britain by the polling company TNS Sofres revealed that more than 50 percent of men who suffer from impotence said it caused a loss of self-confidence and self-esteem. Fourteen percent of men with the problem said it affected their family life and six percent reported it had caused a break up in a relationship.  

According to the survey, fourteen percent of British men who suffer from impotence have suicidal thoughts and many wait years before seeking help.  

Vincenzo Myron, professor of urology at the University Federico II of Naples and secretary general of the Italian Society of Urology, says: “(In Italy) about 3 million men suffering from erectile dysfunction.”  

“Erectile function, in general, is a marker for overall cardiovascular function” Irwin Goldstein, editor-in-chief of The Journal of Sexual Medicine, said in a statement.    

A study recently presented at a meeting of the European Association of Urology showed that erectile dysfunction isn’t being treated very often, with only 25.4 percent of men in the study being treated for the condition. According to the Cleveland Clinic, as many as 52 percent of men experience erectile dysfunction, with it affecting 40 percent of men age 40, and 70 percent of men age 70. Men who have heart disease, diabetes and are taking certain medications have higher risks of experiencing erectile dysfunction.    

Men with ED are also at higher risk for developing many diseases, including heart disease, arteriosclerosis (hardening of the arteries), diabetes mellitus, renal failure, liver and vascular disease. All these diseases have been associated with ED.  

ED is a particularly strong predictor of your risk for heart disease and heart attacks. In a 2010 study from the University of Saarland in Germany, researchers found that having erectile dysfunction raises your risk of a heart attack (myocardial infarction) by 200%, your riskfor heart failure by 20% and your risk of suffering a stroke by 10%.  

Perhaps even more significantly, erectile dysfunction raises your risk of dying from all causes by 84%.  

Even more worrisome is the staggering percentage of male infertility. According to the American Chemical Society, sperm count in men worldwide is fifty percent lower than it was fifty years ago. The recent boom in sales of Viagra indicates just how popular a potency drug can be in a sex-oriented society when, ironically, such a large number of men can't perform sexually.
