A new study finds that the ‘quality’ of a man’s sperm correlates with their longevity.
Sperm may be the canaries in the coalmine for male health, according to research that reveals men with higher-quality semen live longer.
Danish scientists analysed samples from nearly 80,000 men and found that those who produced more than 120 million swimming sperm per ejaculate lived two to three years longer than those who produced fewer than 5 million.
The men with the highest-quality sperm lived to 80.3 years old on average, compared with 77.6 for those with the poorest-quality sperm, the researchers report in Human Reproduction.
“It really seems to be that the better the semen quality, the longer the survival,” said Dr Lærke Priskorn, an epidemiologist at Copenhagen university hospital, who led the study with Dr Niels Jørgensen, an andrologist at the hospital.
This is a major longitudinal study with a large sample of 60,000 people done over 30 years. I hesitate to critique scientific research based on newspaper reports but what one is to do with this information beats me, and the report’s only statement about possible benefits is rather weak.
The researchers now want to find out which diseases are more common in men with poor semen quality. If particular conditions are identified, doctors could ultimately advise men on preventive action should sperm analysis show they are at risk.

Women have long complained that much more time and money and effort is spent on research on even relatively minor aspects of men’s health while research on women’s health is underserved. This kind of news will lend support to that belief.
