<p>Researchers with the Chinese Medical Association say among men over 40, at least 40 percent experience male impotence, a sexual dysfunction characterised by the inability to develop or maintain an erection of the penis, the China Daily reported Monday.<br /><br />About 83 percent of the sufferers in China "never sought medical treatment for the disease", said Wang Xiaofeng, director of the urology surgery department with Peking University People's Hospital. <br /><br />Wang said poor public awareness and the underlying social stigma related to the disease are mainly to be blamed.<br /><br />He made the remarks while making a report during the Fifth China Andrology Forum in Beijing over the weekend. <br /><br />The released figures are based on surveys on erectile dysfunction carried out in 11 cities. <br />Men who reported being sometimes able or never able to get and keep an erection in the past three months were defined as suffering erectile dysfunction, Wang said. <br /><br />For the majority of sufferers the cause was psychological, only 7.2 percent was caused by physical conditions. Some 30 percent suffered from both mental and physical causes, he said. <br /><br />The research showed that lifestyle changes like more exercises and measures to prevent cardiovascular disease and diabetes, would help prevent erectile function. <br /><br />In a 2009 survey on people's sex life satisfaction, China ranked 11th among 13 Asian countries. <br /></p>
