1115: Down for the Sperm Count

Irina Mindlis, Research Project Manager, Mount Sinai School of Medicine & Co-Author of “Temporal Trends in Sperm Count: A Systematic Review and Meta-Regression Analysis”

Why have men in the developed world lost 59.3% of their total sperm count?

If one is concerned about the future of humanity, the sperm count numbers are truly daunting.

• In the past 40 years, sperm counts around the world declined by 50%, to 47 million sperm per milliliter, and the counts are continuing to decline.

• The most significant declines were found in the developed world – North America, Europe, Australia and New Zealand – where men have lost 59.3% of their total sperm count.

• 50% of men in the developed world are now at the point of being – or are – unable to reproduce.

• No declines in sperm counts were found in men from developing nations.

Commenting on the research papers that revealed the numbers, Danish fertility researcher Dr. Neils Skakkebaek said,

“Here in Denmark, there is an epidemic of infertility. More than 20% of Danish men do not father children. Most worryingly is that semen quality is in general so poor that an average young Danish man has much fewer sperm than men had a couple of generations ago, and more than 90% of their sperm are abnormal.”

That men in developed nations are losing their fertility, while men in developing nations are losing none, leads us to ask…

Why have men in the developed world lost 59.3% of their total sperm count?
