Skyrocketing Male Infertility

Human fertility is in a downward spiral, scientists warn and modern life — with its technological and chemical “progress” — is likely to blame. Female infertility tends to get the most attention, but in this case, it’s male infertility that has made headlines, as recent research shows sperm concentration and quality has dramatically declined in recent decades.1,2,3,4,5

According to the first of two recently published papers,6 a meta-analysis of 185 studies and the largest of its kind, sperm counts around the world declined by more than 50 percent, to 47 million sperm per milliliter (mL), between 1973 and 2013, and continue to dwindle.

The most significant declines were found in samples from men in North America, Europe, Australia and New Zealand, where many had sperm concentrations below 40 million/mL. (Men suspected of infertility, such as those attending IVF clinics, were excluded from the study.) Overall, men in these countries had a 52.4 percent decline in sperm concentration and a 59.3 percent decline in total sperm count (sperm concentration multiplied by the total volume of an ejaculate)

Male Infertility Rates Warn of Impending Human Extinction

According to the World Health Organization, 40 million sperm per mL is considered the cutoff point at which a man will have trouble fertilizing an egg, which means half of the men in most developed nations are near or at the point of being infertile. South American, Asian and African men had no noticeable decline, although this discrepancy could be due to the smaller sample sizes obtained from those countries.
