Hepatitis C May Cause Erectile Dysfunction

NEW YORK (Reuters Health) - Infection with the hepatitis C virus may increase the risk of erectile dysfunction, the results of a new study suggest.
 
The virus itself may play a direct role in causing erectile dysfunction, the findings suggest, since investigators took into account liver failure and treatment for hepatitis C, both of which are suspected of increasing the risk of erectile dysfunction in men with hepatitis C.
 
Nearly 4 million American have hepatitis C, making it the most common chronic viral infection in the US. Chronic inflammation of the liver develops in many patients, and about 20% of people with hepatitis C will develop cirrhosis, a severe and sometimes fatal scarring of the liver. Cirrhosis increases the risk of liver cancer.
 
Hepatitis is spread through contact with blood and other body fluids, but the route of transmission remains undetermined in a substantial percentage of infections. People who share needles to inject drugs have a high risk of contracting the disease.
 
Cases of erectile dysfunction in men with hepatitis C have been reported, but it is unclear whether the blame should be placed on the virus itself or on poor liver function caused by the infection. A drug used to treat hepatitis C, interferon alfa, is another prime suspect.
 
A team led by Dr. Clodoveo Ferri of the University of Pisa in Italy, compared the frequency of erectile dysfunction in 207 men with hepatitis C and 207 healthy men. Among men with hepatitis C, 39% had erectile dysfunction, compared with 14% of healthy men, according to a report in the August 14th issue of the Journal of the American Medical Association ( news - web sites).
 
But neither the presence of liver failure nor interferon alfa therapy seemed to affect a man's odds of having erectile dysfunction, according to the researchers.
 
"Nonetheless, both liver failure and interferon alfa may also contribute to erectile dysfunction, and treatment should be individualized," Ferri's team writes. Suggesting that antiviral treatment may relieve erectile dysfunction, the researchers recommend that this approach be studied in clinical trials. They also advise physicians to consider hepatitis C infection when diagnosing erectile dysfunction.
