COUNT DOWN
How Our Modern World is Threatening Sperm Counts, Sexual Development, and the Future of the Human Race
Dr. Swan, a world-renowned scientist who has been studying the effects of environmental influences on human reproductive development and health for more than two decades, explores the implications of a 2017 study she published that drew global attention from both the scientific community and the media.
Ranked #26 among all referenced scientific papers ever published worldwide, "Temporal Trends in Sperm Count: a systematic review and meta-regression analysis" tracked global decline in male fertility since 1973.
Between 1973 and 2011, sperm concentration dropped more than 52% among men in Western countries and the total sperm count fell by more than 59%. These conclusions were drawn after examining the findings from 185 studies, involving 52,935 men, conducted during this 38 year period. It included ordinary, everyday men, and while there was much less data from men from South America, Asia, and Africa, recent statistics indicate to a decline in those countries as well.
Swan claims that we're in the midst of a sperm-decline crisis that threatens to foil fertility, put our collective fecundity on notice, and endanger the health of the planet. Some scientists are describing the sperm count decline as a signal to an invisible but dangerous disruption in the safety of the environment that could affect the very survival of the human race.
The questions it raises are without easy answers, and the implications extend far beyond the stuff of dystopian science fiction.
Shanna H. Swan, Ph.D., is one of the leading environmental and reproductive epidemiologists in the world, a professor of environmental health, and an award-winning scientist whose work examines the impact of environmental exposures on reproductive health and the neurodevelopment of children. She's published more than 200 scientific papers and myriad book chapters and has been featured in extensive media coverage around the world. Stacey Colino is an award-winning writer specializing in health and environmental issues and a regular contributor to U.S. News & World Report. She is the co-author with David Katz, M.D., of Disease-Proof: The Remarkable Truth About What Makes Us Well; Strong is the New Skinny with Jennifer Cohen, Good Food Fast! with Jason Roberts, and Taking Back the Month with Diana Taylor, R.N., Ph.D.
