Testosterone Tumbling in American Males Who controls the food controls the people. "It is in the biological sciences that the most exciting possibilities suggest themselves... I will only speculate on a few among these possibilities which might have great effects on human life. "I have already referred to the possibility of quite new sources of food and I need not enlarge on that further. ". . . hormones, those internal chemical secretions which so largely regulate the operations of the human body. The artificial use of hormones has already been shown to have profound effects on the behaviour of animals. . . might have similar effects on man. . . ". . . might be a drug, which... removed the urgency of sexual desire, and so reproduced in humanity the status of workers in a beehive. "To produce effects of these kinds there must be a master and the master must be above and not subject to the procedure he is enforcing on his subjects." - Excerpt From "The Next Million Years", (1952) by Charles Galton Darwin, grandson of evolutionist Charles R. Darwin Related: > Preschool Puberty, and a Search for the Causes > Food wrap linked to prostate cancer: Lines tin cans "Bisphenol A is widely used in the food industry to make polycarbonate drinks bottles and the resins used to line tin cans, even though it is known to leach into food and has long been suspected of disrupting human sex hormones."The testosterone-fueled American male may be losing his punch. Over the past two decades, levels of the sex hormone in U.S. men have been falling steadily, a new study finds. For example, average total testosterone levels in men aged 65 to 69 fell from 503 nanograms/decileter (ng/dL) in 1988 to 423 ng/dL in 2003. The reasons for this trend are unclear, said researchers at the New England Research Institutes in Waterdown, Mass. They noted that neither aging nor certain other health factors, such as smoking or obesity, can fully explain the decline. "Male serum testosterone levels appear to vary by generation, even after age is taken into account," study lead author Thomas G. Travison said in a prepared statement. Testosterone is the primary male sex hormone and plays an important role in maintaining bone and muscle mass. Low testosterone levels have been linked to health problems, including lowered libido and diabetes. It's normal for men's testosterone levels to peak in their late 20s and then start to gradually decline, experts say. But this study found that overall testosterone levels are lower than they were 20 years ago. "In 1988, men who were 50 years and older had higher serum testosterone concentrations than did comparable 50-year-old men in 1996. This suggests that some factor other than age may be contributing to the observed declines in testosterone over time," Travison said. He and his colleagues analyzed blood samples -- along with health and other information -- from about 1,500 men in the greater Boston area who took part in the Massachusetts Male Aging Study. That study collected data in 1987-89, 1995-97, and 2002-04. "This analysis deals with men who were born between 1915 and 1945, but our baseline data were not obtained until the late 1980s, when the elder subjects were about 70 years old, and the youngest about 45," Travison said. "Events occurring in earlier decades could certainly help explain our results, if their effects persisted into recent years," he noted. The findings were published in the Journal of Clinical Endocrinology and Metabolism.

Not only in American males... ----------------------------------------------------------- No aspect of the extensive scientific evidence considered in Our Stolen Future commanded more media attention than the controversial reports of declining sperm counts, launched by the 1992 paper by Carlsen et al. reporting 40% decline in sperm count over the second half of the 20th century. Animal studies clearly demonstrated that in utero exposure to low levels of endocrine disruptors at critical times in development cause low sperm counts and other sperm maladies. Human studies document exposure to these compounds. Data presented by Carlsen et al. suggested that major declines were occurring in people. <a href="http://www.ourstolenfuture.org/NewScience/reproduction/sperm/sperm.htm">www.ourstolenfuture.org</a> ----------------------------------------------------------- Is it a pharmafeminist plot to undermine manhood and rebalance the Yin and The Yang? I doubt it.

I'm sure I read that estrogen in the water supply is affecting frogs and other animals due to all the birth-control pill runoff from humans. Anti-depressents are getting into the water supply at an alarming rate, too. We are all down-stream and down-wind on this planet. (Something to do with the shape.)

I heard the eostrogen tale too and there's probably something in it but it isn't the full story. I also heard somewhere of the fifty year water cycle which says it takes fifty years for the water dumped on land to seep out. Think what went into the ground over the last fifty years and imagine it seeping into your water supply for the next fifty. Humankind has some serious adjustments to make.

When push comes to shove here, few young men will have the cajones to fight back. The NWO takeover will be a snap. Listening to current rock music, I hear nothing but whiny, whipped shoe-gazers caterwauling about whatever. Where are the Gregg Allmans, John Fogartys, and Eric Burdons of yesteryear? No doubt, America is being demasculated, and it's no accident.

<a href="http://www.panna.org/resources/panups/panup_20020802.dv.html">New Evidence That Endocrine Disruptors Block Sperm Function</a> New Evidence That Endocrine Disruptors Block Sperm Function August 2, 2002 The link between male fertility and hormone disrupting chemicals is now more fully understood. A new study shows that adult sperm, when exposed to hormone disrupting chemicals (often called endocrine disruptors), mature too quickly and fail to reach and fertilize the egg. Dozens of pesticides are known or suspected endocrine disruptors. The list includes widely used carbamates such as aldicarb and carbaryl, common organophosphates (e.g., malathion and chlopyrifos), and persistent chlorinated pesticides such as endosulfan, lindane and DDT. Individuals face potential exposure to endocrine disrupting pesticides through food residues, home pesticide use, and soil, water and air contaminated by agricultural pesticide use. The study, released in early July 2002 at Europe's annual human reproduction conference by scientists from King's College in London, provides the first direct evidence that endocrine disruptors affect sperm function. For many years, the debate over male fertility has focused on the effects of prenatal exposure to such compounds on development of testicles in infants and evidence of declining sperm counts worldwide. In the past ten years, dozens of studies have linked endocrine disrupting chemicals to a number of reproductive and other health effects. The chemicals closely mimic naturally occurring hormones and can disrupt the functioning of hormone systems in humans and other animals at very low levels of exposure. Dr. Theo Colburn's research more than a decade ago linking reproductive failure in alligators with chemical exposure led researchers to further explore the reproductive and other effects of this class of chemicals. Exposure to endocrine disrupting pesticides adds to an individual's ongoing exposure to dozens of other chemicals that also mimic hormones, from by-products of industrial production and incineration (dioxins and furans) to chemicals in widespread use in formulating products for everyday use. Phthalates, for example, are endocrine disrupting chemicals used as softening agents in many plastic products (including medical devices) and in beauty products such as deodorants, lotions and nail polish. The 12 chemicals (nine pesticides) to be banned worldwide under the international Stockholm Convention on Persistent Organic Pollutants are all known or suspected endocrine disruptors. While most of these chemicals have been banned in industrialized countries for many years, low-level residues continue to be found in the U.S. food supply (See Nowhere to Hide: Persistent Toxic Chemicals in the U.S. Food Supply, PANNA & Commonweal, 2001 on the PANNA website: http://www.panna.org/resources/document ... il.dv.html.) In the sperm function study, researchers found that mouse sperm bathed in low levels of endocrine disrupting chemicals matured early, releasing the enzymes they need to penetrate the egg's jelly coat before making contact with the egg. Scientists note that human sperm is known to be even more sensitive than mouse sperm to female hormones such as estrogen. The lead researcher, Dr. Lynn Fraser, also notes that given the wide variety of endocrine disruptors present in the environment, it is quite possible that sperm face exposure to multiple endocrine disrupting chemicals, with possible synergistic effects. This evidence of the direct effects of endocrine disruptors on sperm function adds a new dimension to the ongoing debate over the links between male fertility and chemical exposures. Declining sperm counts became a focus of discussion in 1992, when a landmark study was released by Carlsen et al reporting a 40% decline in sperm count worldwide over the second half of the 20th century. The study initiated a decade's heated exchange within the scientific community over sperm count data, and spurred many follow up studies producing a range of conflicting results. There now appears to be agreement that there have been significant sperm count declines, with unexplained regional variations. There is no agreed explanation for the declines, and endocrine disruption is considered one of the possible contributing sources. The other area of intensive research linking chemicals and male fertility focuses on the increasing rates of "cryptorchidism," or undescended testicles, which can result in infertility. Here the discussion is less controversial, as evidence from both animal studies and studies of children with cryptorchidism point toward a link with endocrine disrupting chemicals, and the process through which chemicals can block the hormonal signal controlling testicular descent is clearly understood. The recent evidence on blocked sperm function adds new urgency to regulatory efforts to understand and address endocrine disruptors. The U.S. Environmental Protection Agency's Endocrine Disruptor Screening Program, established in 1996 under the Food Quality Protection Act to test pesticides and other chemicals for endocrine disrupting effects and prioritize them for regulatory action, has been unacceptably slow to identify and recommend action on priority chemicals. Evidence of the health effects of endocrine disrupting chemicals continues to mount. In terms of male fertility, it now seems that these ubiquitous chemicals are a significant threat at various stages, from testicular development to sperm production to the functionality of healthy sperm. This class of chemicals appears to be threatening male fertility on several fronts. <a href="http://www.pan-uk.org/pestnews/actives/endocrin.htm">Endocrine disrupting pesticides</a> ** "..Other man made chemicals, with unintentional hormone-like activity include: pesticides such as DDT, vinclozolin, endosulfan, toxaphene, dieldrin, and DBCP, and industrial chemicals and byproducts such as polychlorinated biphenyls (PCBs), dioxins, and phenols. Some of these phenols are breakdown products of surfactants, found in soaps and detergents. Also implicated are heavy metals, plastics, cosmetics, textiles, paints, lubricants. Sewage treatment effluent may contain a variety of natural and man made endocrine disruptors, including natural hormones from animal and human waste. Currently, there are no standard tests to determine if a chemical is an endocrine disruptor. .."<a href="http://extoxnet.orst.edu/faqs/pesticide/endocrine.htm">link</a> <a href="http://www.mindfully.org/Pesticide/EDs-PWG-16jun01.htm">Fundamentals of Naturopathic Endocrinology </a>  Contents * What are Endocrine Disruptors (EDs)? * The Endocrine System * The Creation of EDs * Bioaccumulation * Synergy * Human Exposure * Health Effects of Endocrine Disruptors * Children are at Greater Risk * Measure EDs in Parts Per Trillion * Why Haven't I heard About EDs? * What Do Chemical Manufacturers Have to Say? * Isn't the Government Watching Out For Our Safety? * Precautionary Principle * Avoiding EDs * Recommendations
