Comprehensive study shows a significant ongoing decline in sperm counts of Western men

Comprehensive study shows a significant ongoing decline in sperm counts of Western men: A rigorous and comprehensive meta-analysis of data collected between 1973 and 2011 finds that among men from Western countries, sperm concentration declined by more than 50 percent, with no evidence of a 'leveling off' in recent years. These findings strongly suggest a significant decline in male reproductive health that has serious implications beyond fertility and reproduction, given recent evidence linking poor semen quality with higher risk of hospitalization and death.
