A decade-long study of 135,000 men found that those who remained child-free had a higher risk of dying from heart disease than those who ‘sowed their oats.’ U.S researchers said it raised the possibility that infertility may be a potential early warning sign of future heart trouble. ‘There is emerging evidence to suggest that infertility may be a window into a man’s later health,’ said study leader Dr Michael Eisenberg of Stanford University in California. He said men who are infertile have a higher risk of certain cancers, and his team wanted to look for other signs that infertility might be playing a role later in a man’s life. The researchers, reporting in the journal Human Reproduction, followed more than 130,000 men who were retired and over 50 for a decade.
