Countdown: An expert predicts the West's sperm count will soon be zero
Call it an existential crisis. According to a 2017 analysis co-authored by Shanna, the Western world's collective swimmers have been taking a dive — between 1973 and 2011, there was a 59% decrease in sperm count.

Pete Myers: Our failure on fertility
Your hormones have been hijacked.
<p>Your body's astonishing, finely calibrated signal system – a system that controls everything from your weight to your fertility to your mood – has been scrambled by loosely regulated chemicals manufacturers use in a myriad of ways including in consumer products.</p><p>These hijackers – known to scientists as "endocrine-disrupting chemicals" – are threatening our existence as a species. Driving this problem are chemical companies focused only on cheap plastics and regulators unwilling to do anything about it.</p><p>I know that sounds dramatic. I wish it weren't true. But thousands of rigorous research projects costing hundreds of millions of dollars over the past two decades has made it clear.</p><p>Male fertility is dropping precipitously, and it is clear that these chemicals are at the heart of it. I'm half the man my grandfather was, and my grandsons will be half the man I am. In some countries, half of all couples seeking pregnancy require medical intervention.</p><p>This is what's so important about a ground-breaking book on fertility, <a href="https://www.shannaswan.com/" target="_blank">"Count Down,"</a> published this week by Shanna Swan, my good friend and a pioneering reproductive epidemiologist at Mount Sinai's Icahn School of Medicine. She lays out, in vivid detail, the environmental factors contributing to dropping fertility rates worldwide.</p><p>Grounded in irrefutable science and laced with dry, engaging wit, this epic book asks monumental questions. If you dream of children, grandchildren and generations beyond, you must read it.</p><p>But the problems with endocrine-disrupting chemicals do not stop at our bodies.</p>

Web of life at risk
<p>The web of life on which we depend is also at risk, as these chemicals work their way through sensitive and complex ecosystems. For example, insect populations are collapsing worldwide, and the science shows that these chemicals are playing a significant role in this. When combined with climate change and habitat destruction, the pressures are enormous.</p><p>We also know that early exposure to endocrine-disrupting chemicals reduces IQ. To paraphrase another scientist, we may not be smart enough to solve this problem before we realize how bad it is.</p><p>Our hospitals are full of patients whose chronic diseases are triggered and/or worsened by endocrine-disrupting chemical's, including diabetes, obesity, and cancer. Setting aside for the moment the astonishing emotional cost of not being able to conceive or being saddled with chronic, debilitating illnesses, the impact on our national health, productivity and health care costs is clearly in the hundreds of billions of dollars.</p><p>My granddaughter, now 2 years old, was born in Alta Bates Hospital in Oakland, California, two months premature. The plastics in the devices that were used to save her life were essential. Yet I'd bet a year's salary that the reason she was born prematurely is that my daughter was living in San Francisco during the fires in Paradise, California, of early November 2018, when thousands of pounds of plastics burned for days and coated the Bay Area with their smoke.

We need to test those that we use now. Not a single plastic molecule now in our environment has been fully tested for endocrine-disrupting properties. Not a single one. </p><p> At Environmental Health Sciences, we've been working to reform regulatory science for decades. We know that the Food and Drug Administration is using inaccurate standards for testing derived from 16th century science. We know that tiny amounts of these chemicals can corrupt hormonal responses. The high dose testing used by the FDA are utterly incapable of detecting these low dose effects. Hence federal regulatory standards—what is safe and what is not—are laughable and irrelevant to human health.</p><p> We need all sectors of our economy and society involved in this. Every single victory we've had in this work has included demand for safer materials and better products from the end consumer. It is an absurd situation that we live in this First World economy, where any number of conveniences and products are available, yet we remain awash with endocrine-disrupting chemicals that are hijacking our most sensitive and essential human functions. </p><p> Please excuse my scientific jargon - but that's just nuts.

WATCH: Fertility crisis leaves little time for solutions
On fertility, we are running out of time.
And the growing number of plastics in our lives are accelerating the crunch.
<p>That's the core message in a pair of webinars this week on humanity's infertility crisis, centered around Tuesday's publication of "<a href="https://www.shannaswan.com/" target="_blank">Count Down</a>," by reproductive health expert Dr. Shanna Swan.</p><p>Worldwide, sperm counts have declined 50 percent in males the past 50 years, Swan noted. Other key aspects of human fertility – miscarriages, testosterone levels, premature egg depletion, difficulty conceiving – are all changing at a similar rate.</p><p>The data worldwide are so clear and so consistent, Swan noted on a webinar hosted by <a href="https://www.plasticpollutioncoalition.org/ppc-webinar-022421" target="_blank">Plastic Pollution Coalition</a> Wednesday, that the trend is unmistakable: by 2045 median sperm counts in men are headed toward zero.</p><p>"This means that half the men would have zero" viable sperm, Swan said, "and the rest would have very close to zero."</p><p>"We want to push this curve in a direction that keeps it from hitting zero."</p>

Count Down: Hormonal havoc in our midst
Editor's note: The following is an excerpt from the book "Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race" by EHS adjunct scientist Shanna Swan, PhD.

The drop heard round the world

<p>In late July 2017, it seemed as if every media outlet around the globe had become obsessed with the state of human sperm counts. <em>Psychology Today </em>cried, "Going, Going, Gone? Human Sperm Counts Are Plunging," while the BBC declared, "Sperm Count Drop Could Make Humans Extinct," and the <em>Financial Times </em>announced, "Urgent Wake-Up Call' for Male Health as Sperm Counts Plummet." A month later, <em>Newsweek </em>published a major cover story on the same subject: "Who's Killing America's Sperm?" </p><p>By the end of the year, my scientific paper "Temporal Trends in Sperm Count: A Systematic Review and Meta-Regression Analysis," which sparked these stories—and hundreds of others around the world— was ranked number 26 among all referenced scientific papers published worldwide, according to Altmetric's 2017 report. This truly was the drop heard round the world.</p>Chance of extinction?
<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTY0MzQzMS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2NzAzNjk0MH0.vs_JYl7Mja_8p3COxXUEBNCbKs5HH11riVvI2Tsnk_I/img.jpg?width=980" id="bfdc9" class="rm-shortcode" data-rm-shortcode-id="61019d548f67fe2b9d9897277d982554" data-rm-shortcode-name="rebelmouse-image" data-width="5760" data-height="3840" />Credit: Johnny Cohen/Unsplash
<p>These days, the world as we've known it feels as though it's changing at warp speed. The same could be said for the status of the human race. It's not only that sperm counts have plummeted by 50 percent in the last forty years; it's also that this alarming rate of decline could mean the human race will be unable to reproduce itself if the trend continues. As my study collaborator Hagai Levine, MD, asks, "What will happen in the future—will sperm count reach zero? Is there a chance that this decline would lead to extinction of the human species? Given the extinction of multiple species, often associated with man-made environmental disruption, this is certainly possible. Even if there is low probability for such a scenario, given the horrific implications, we have to do our best to prevent it."</p><p>This is especially worrisome because the sperm-count decline that's occurring in Western countries is unabating; it's steep, significant, and continuing, with no signs of tapering off. As Danish researcher and clinician Niels Skakkebaek, MD, who was the first person to alert the scientific community to the role of environmental factors in sperm decline, said, "It's an inconvenient message, but the species is under threat, and that should be a wake-up call to all of us. If this doesn't change in a generation, it is going to be an enormously different society for our grandchildren and their children." </p><p>Indeed, if the decline continues at the same rate, by 2050 many couples will need to turn to technology— such as assisted reproduction, frozen embryos, even eggs and sperm that were recreated from other cells in the laboratory (yes, this is actually being one)—to reproduce.</p>A dystopian future?

<p>Some of what we've been thinking of as fiction, from stories such as <em>Th</em><em>e Handmaid's Tale </em>and <em>Children of Men</em>, is rapidly becoming reality. In the winter of 2017, I presented my sperm-decline findings at the One Health, One Planet conference, which focused on the interconnected health of different species on the planet, the damage being inflicted by our mad "industrialization" of the environment, and its devastating effects on frogs, birds, polar bears, and other species. After presenting the results of our analysis, which were shocking enough to the audience, I spoke for the first time about what sperm decline could mean for <em>Homo Sapiens</em>. That night, I awoke from a dream, feeling incredibly anxious as I suddenly realized the full implications of the story I'd put together— that given the declines in sperm count and testosterone levels and the increases in hormonally active chemicals that are being spewed into the environment, we really <em>are </em>in a dangerous situation for mankind and world fertility.</p><p>This was no longer only a matter of scientific study for me. I felt and remain genuinely <em>scared </em>by these findings on a personal level.</p><p>In some ways, the picture looks even worse when you delve deeper because it's not just an issue for men. Women, children, and other species are also having their reproductive development and function commandeered in a dysfunctional direction. In some countries throughout the world, including the United States, a massive sexual slump is underway, due to declines in people's sex drives and interest in sexual activity; men, including younger guys, are also experiencing greater rates of erectile dysfunction. In animals, there have been changes in mating behavior, with more reports of male turtles humping other male turtles, and female fish and frogs becoming masculinized after being exposed to certain chemicals.</p><p>Taken together, these trends are causing scientists and environmentalists to wonder, how and why could this be happening? The answer is complicated.</p>About the author

Dismaying biological realities

<p>It's hardly a news flash that human beings often take things for granted. Fertility is no exception—unless people discover they have a problem in this area. As with having access to basic necessities and certain fundamental freedoms, many people take it as a given that they'll be able to have babies when the time is right and help perpetuate the species. All of these assumptions reside under the notion that we don't always appreciate what we've got till it's gone, as folk singer/songwriter Joni Mitchell suggested in her hit song "Big Yellow Taxi."</p><p>It's difficult enough for a man or a woman, when experiencing reproductive disorders or fertility troubles, to accept that he or she may not be able to have children. Now there's an even greater challenge as human beings collectively are forced to contend with some dismaying biological realities. In Western countries, sperm counts and men's testosterone levels have declined dramatically over the last four decades, as my own research and that of others has found. Also, increasing numbers of girls are experiencing early puberty, and grown women are losing good-quality eggs at younger ages than expected; they're also suffering more miscarriages.</p>An age of reproductive reckoning
<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTYzNDA0MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY3MDUyMjE5MX0.QKEuCNb4j_CFtTpAUFj6L40qTA0ow_FuUug_xdG8b8k/img.jpg?width=980" id="6e293" class="rm-shortcode" data-rm-shortcode-id="45ba99f013c6f6d3802fb3a7da5b219f" data-rm-shortcode-name="rebelmouse-image" alt="Human fertility decline" data-width="5184" data-height="3456" />Credit: Eva Hartnagel/Unsplash
<p>It's no longer business as usual when it comes to human reproduction. Other species are suffering, too. There's been a rise of abnormal genitals in wildlife, including unusually small penises in alligators, panthers, and mink, as well as an increase in fish, frogs, birds, and snapping turtles that have both male and female gonads or ambiguous genitalia. At first glance, these issues may seem like bizarre anomalies or cruel tricks from Mother Nature—but they're all signs that something very wrong is happening in our midst. Exactly what that culprit is continues to be hotly debated, but evidence pointing to likely suspects is mounting on a regular basis.</p><p>This much is clear: The problem isn't that something is inherently wrong with the human body as it has evolved over time; it's that chemicals in our environment and unhealthy lifestyle practices in our modern world are disrupting our hormonal balance, causing varying degrees of reproductive havoc that can foil fertility and lead to long-term health problems even after one has left the reproductive years. Similar effects are occurring among other species, adding up to widespread reproductive shock. Simply put, we're living in an age of reproductive reckoning that is having reverberating effects across the planet.</p>Putting the puzzle together

<p>If these alarming trends continue unabated, it's difficult to predict what the world will look like in a hundred years. What does this dramatic decline in sperm count portend if it stays on its current trajectory? Does it signal the beginning of the end of the human race—or that we're on the brink of extinction? Does the environmental emasculation of wildlife suggest that the earth really is becoming much less habitable? Are we on the verge of experiencing a global existential crisis? These are good questions, and we don't have clear answers to them, at least not yet. But pieces of the puzzle are being put together, as you'll see in the chapters that follow. You'll learn more about the breadth of these scary declines in sperm counts and other aspects of reproductive function, as well as the factors that are likely to blame for these unfortunate effects in human beings and other species, based on scientific research. The following is clear: The current state of reproductive affairs can't continue much longer without threatening human survival.</p>About the author
