New research suggests that sperm counts are declining among men in North America, Europe, and Australia. Worse, it also appears that sperm quality has seen better days among Western men, with both metrics declining drastically since the 1970s.
According to a report from USA Today, the new study suggests that for men in the Western world, sperm count declined by close to 60 percent as of 2011, as compared to figures from 1973. This was based on data from 185 previous studies profiling close to 43,000 men in North America, Europe, Australia, and New Zealand, with the subjects getting sperm counts because of infertility, or due to other medical problems. As USA Today noted, this could potentially skew the results of the recent study, as the studies didn’t include perfectly healthy men.
