The Devastating Impact of Pseudo Estrogens in Our Environment| Updated: Jul 08, 2019
Worse, those otters are also likely to have undescended testicles and cysts on the tubes that transport their sperm.
These worrisome studies have implications for human males as well despite the fact that men don’t have a baculum.
The reason is that the otter problem is but one manifestation of a worldwide increase in male reproductive birth defects. Indeed, it’s happening in all species tested, and also includes decreases in both the quality and quantity of sperm.
The bad news about otters comes from British scientists working on the Cardiff University Otter Project and at the Chemicals, Health and Environment Monitoring (CHEM) Trust. Between 1992 and 2009, the researchers collected 755 otter carcasses and focused on measuring, weighing and closely examining their reproductive parts.
Although the scientists admit they don’t know for sure what’s causing the changes, they think pseudo estrogen exposure should take the blame. BPA, phthalates and other estrogenic chemicals commonly found in cosmetics, drugs, plastics, cans, takeout food packaging, and pesticides have contaminated the environment, including the rivers where the otters live.
What’s the takeaway for humans regarding the negative health effects of pseudo estrogens? First of all, it’s not just male fertility at stake.
Environmental pseudo estrogens adversely affect women as well, contributing to thyroid disorders, difficulty conceiving, painful menstrual cycles, difficult menopause, and increased breast cancer risk. Secondly, pseudo estrogens polluting our environment play a role in the modern epidemic of depression, anxiety, ADD/ADHD and other mental health disorders.
Given the extent of the problem, it’s easy to fall into despair, but the bottom line is every one of us can make dietary and lifestyle choices that will reduce our exposure to pseudo estrogens. These choices include:
- Refusing to buy commercial produce and factory-farmed meats, and opting instead for organic, free-range and pastured foods.
- Investing in the best home water filter system you can afford. Tap water includes environmental estrogens from pesticides and other sources as well as residues from birth control pills and hormone replacement therapies. Good filters also take out fluoride and chlorine, poisons that potentiate estrogens, further putting our thyroids and reproductive systems at risk.
- Purchasing non-toxic toilet paper and feminine hygiene products (vetted sources). These products come in contact with intimate parts of the body where tissues are thin and access to the bloodstream easy, providing yet another worrisome source of exposure. Sadly, many “BPA free” products contain estrogenic BHT or the cousin chemical BPS which is just as toxic.
- Rejecting soy infant formula, and limiting the consumption of soy milk, edamame, and soy protein foods, particularly for children. The presence of soy on this list may surprise people because it does not usually turn up on lists of environmental estrogens. However, all soybeans — organic, hybrid and GMO — contain high levels of plant estrogens (phytoestrogens). Although not identical to human estrogens, they are close enough to cause considerable hormonal havoc. The results are similar to the reproductive tract problems caused by excessive exposure to other environmental estrogens. Eating soy has been linked to hypospadias, a birth defect in which the opening of the penis is located on the underside rather than at the tip. A European Commission study is currently underway, investigating a possible link between vegetarian diets, soy consumption, and hypospadias. While soy consumption is clearly not part of the otter problem, soy should be understood to be one more environmental estrogen capable of contributing to the constellation of birth defects found by the UK researchers in otters, and increasingly prevalent in humans and other species.
In a statement to the UK Daily Mail about the otter research, Gwynne Lyons, director of the CHEM Trust, summed up the situation well:
“These findings highlight that it is time to end the complacency about the effects of pollutants on male reproductive health. . . . The effects reported in otters may be caused by the same EDCs (endocrine disrupting chemicals) that are suspected to contribute to the declining trends in men’s reproductive health and cause testicular cancer, undescended testes and low sperm count. In reality humans and wildlife are exposed to a cocktail of many chemicals every day and some may be adding up to cause problems.”
