What’s Going On with Those Scandinavian Sperm?

Looking around the ever-more-crowded globe, you might conclude that human sperm counts are just fine, thank you very much. Hitting the 7 billion mark as a species can lead to such conclusions. Yet that inference would counter what some involved in the field of endocrine-disruption research have long asserted: that sperm counts have, in fact, been dropping, and a Children of Men scenario of creakingly empty playground swings and absent children’s voices menaces the future of our species
