In a survey published by Chinese Medical Development Research Council 70 percent of Chinese men marked their satisfaction with their sexual life below the "pass score" of 60 points, China.org.cn reports.

The survey polled more than 30,000 men. Pressure from work is the largely to blame, 47 percent of participants cited this as the main reason.

?Lack of exercise is also an issue. Less than 1 percent of young people work out once a week.
