BEIJING (AFP) – The percentage of men showing signs of early ageing in Shanghai, China’s most modern and one of its richest cities, has doubled over the past two decades, state media said, citing a survey.
Symptoms of “male menopause,” which includes weariness, vesicular diseases and deteriorating sexual ability, trouble 20 percent of Shanghai men under the age of 45, the China Daily quoted the survey saying.
This compares to about 10 percent in the early 1980s, according to the survey by Shanghai’s Renji Hospital, the report said.
