Sperm count down nearly 60 percent: Chemicals of concern in food, products, environment one possible suspect

We have posted numerous scientific studies over the past several years linking chemicals like PCBs and phthalates commonly found in processed foods, personal care products and the environment, as linked with infertility.  Now this latest study indicates that sperm counts are way down–a whopping 60 percent drop–in rich countries across the globe.  While there are likely a number of culprits, we should not dismiss the potential role chemicals of concern may be playing in infertility.


Sperm count has fallen by nearly 60 per cent in richer countries

New Scientist

An analysis of research into male fertility suggests that there has been a steep decline in sperm counts for men living in richer nations.

The review pooled data from 185 different studies, and found a 59.3 per cent drop between 1973 and 2011 in the average amount of sperm produced by men from North America, Europe, Australia and New Zealand. No similar pattern was seen in South America, Asia and Africa, although fewer studies had been conducted in these countries…

Exposure to chemicals in the womb, adult exposure to pesticides, smoking, stress and obesity have all previously been linked to lower sperm counts.
