A large study published in the journal Human Reproduction has found a significant link between sperm quality and male longevity. Scientists analyzed data from 78,284 men over a 50-year period and found that men with higher total motile sperm counts were more likely to live longer and healthier lives.
According to the results, men with a count of more than 120 million motile sperm can expect to live 2.7 years longer than those with a count of 0 to 5 million.
The study also showed that all sperm quality parameters, such as sperm volume, sperm concentration, and motility, were negatively correlated with mortality.
“We observed a clear negative association between all sperm parameters and overall mortality,” the study authors note. “These associations were not explained by education level or medical conditions at the time of semen evaluation.”
The researchers emphasize that men with impaired sperm quality may have less healthy aging and need early diagnosis. However, further research is needed to identify specific biomarkers that can help identify men at increased risk.
