Sperm Counts Drop Precipitously in Western Nations

Sperm Counts Drop Precipitously in Western Nations

Riverside, CA

New Science magazine recently reported a study has again confirmed observations made by smaller studies in recent years “that there has been a steep decline in sperm counts for men living in richer nations.” 

According to the report, to complete the analysis, data was pooled from 185 separate studies. The investigators found a 59.3 per cent drop in the average amount of sperm produced by men from North America, Europe, Australia and New Zealand between the years 1973 and 2011. Interestingly, this pattern did not exist in South America, Asia, and Africa, although fewer studies have been conducted in those countries. 

When the report was published, Hagai Levine of the Hebrew University of Jerusalem, who worked on the analysis, said, “Given the importance of sperm counts for male fertility and human health, this study is an urgent wake-up call for researchers and health authorities around the world to investigate the causes of the sharp, ongoing drop in sperm count.” 

Another member of the analysis group, Shanna Swan of the Icahn School of Medicine at Mount Sinai, New York, noted, “The fact that the decline is seen in Western countries strongly suggests that chemicals in commerce are playing a causal role in this trend.”
