Real patient story — shared publicly by Dr. Shanna Swan on Joe Rogan Experience #2476
A man came in with severely low testosterone. Healthy lifestyle. No obvious cause. Testing revealed extremely high levels of microplastics and plastic-derived chemicals in his body. He eliminated every plastic he could find — the coffee machine, the water bottles, the food containers, all of it. His testosterone climbed to 1,200 ng/dL. Naturally. No injections. No therapy. The plastic was the problem.
That story isn’t an outlier. It’s a mechanism I see echoed in my practice regularly. And it points to something most doctors — and most testosterone clinics — never check: the chemical load that may be suppressing your hormones before you ever consider treatment.
I’m Dr. Michael Duben, a board-certified endocrinologist at Restore Health in Fairfield, CT. I trained at Mount Sinai and Albert Einstein College of Medicine, and I’ve spent over 20 years in clinical endocrinology. Before I prescribe testosterone to any man, I want to know why it’s low. In many cases, the answer involves what’s in his water, his food packaging, his cookware, and his grooming products. This post is about those chemicals — what they are, what they’re doing to you, and what to actually do about it.
This is exactly what I look for at Restore Health before ever prescribing testosterone. See my full guide to low testosterone treatment and men’s sexual health for the bigger picture.
First: What Are These Things, Actually?
The terms get thrown around interchangeably. They’re not the same thing. Here’s the short version.
Plastics vs. Plasticizers
Plastics are the solid material — your water bottle, your food container, the tubing inside your coffee maker. Plasticizers (mainly a class of chemicals called phthalates) are what manufacturers add to make plastics soft and flexible. The problem: plasticizers aren’t locked into the plastic. They leach out — into your hot coffee, your food, your skin. Every time you microwave in a plastic container or run boiling water through a plastic coffee machine, you’re getting a dose.
Microplastics
These are tiny plastic fragments — under 5mm — that form when larger plastics break down from heat, UV light, and wear. They’re now found in human blood, lungs, placenta, and brain tissue. In 2024, researchers found microplastic particles inside human testicular tissue in every single sample they tested. The concentrations correlated inversely with sperm count. This isn’t theoretical anymore.
Endocrine Disruptors
This is the umbrella category. An endocrine disruptor is any chemical that interferes with your hormones — mimicking them, blocking them, or scrambling the signals your body uses to regulate testosterone, thyroid, insulin, and more. The key insight: these chemicals don’t need to be present in large amounts to cause harm. Some are more disruptive at low doses than high ones — which is why standard toxicology doesn’t cleanly apply here.
PFAS — “Forever Chemicals”
Around 12,000 synthetic compounds used in non-stick pans, stain-resistant clothing, food packaging, and firefighting foam. They’re called “forever chemicals” because the human body has essentially no way to eliminate them. They accumulate in tissue over your entire lifetime and have been linked to lower free testosterone, thyroid disruption, immune dysfunction, and elevated cancer risk.
Heavy Metals and Pesticides
Lead, mercury, cadmium, and arsenic accumulate in tissue and disrupt the hormone command chain at multiple levels. The herbicide atrazine — used on corn and found widely in U.S. groundwater — directly triggers your body to convert testosterone into estrogen. More on that below.
The Testosterone Killers: Plain-English Breakdown
Here are the major offenders and what each one actually does to a man’s body.
The Testosterone Thief
Phthalates
Directly shut down the cells in your testes responsible for making testosterone. Linked to lower sperm count, reduced motility, and permanent developmental changes with prenatal exposure.
Found in: plastic food containers, cling wrap, coffee pods, fragranced grooming products, vinyl flooring
The Estrogen Impostor
BPA / BPS / BPF (Bisphenols)
Mimics estrogen, telling your brain to produce less testosterone. “BPA-free” alternatives BPS and BPF are equally or more potent. Disrupts sperm production.
Found in: canned food linings, plastic bottles, receipt paper — 10 seconds handling a receipt delivers more BPA than a full day of food packaging
The Forever Hormone Blocker
PFAS
Compete with thyroid hormones, lowering active thyroid levels. Low thyroid raises SHBG — a protein that binds testosterone and takes it out of circulation. Never leave the body.
Found in: non-stick cookware, stain-resistant clothing, microwave popcorn bags, tap water, food packaging
The Testosterone-to-Estrogen Converter
Atrazine
Activates the enzyme that converts your testosterone into estrogen. In famous Florida alligator studies, atrazine-contaminated water dropped male testosterone by 70% and physically altered reproductive anatomy. Second most-used herbicide in the U.S.
Found in: U.S. tap water (especially Midwest), non-organic corn products, groundwater runoff
The Hormone Command Center Saboteur
Lead
Disrupts the pituitary signal (LH) that tells your testes to produce testosterone. Stored in bone for decades — a slow, invisible leak into your bloodstream long after the original exposure.
Found in: old paint, aging plumbing (especially CT homes built before 1986), some imported products
The Thyroid and Testes Wrecker
Mercury
Accumulates directly in testicular tissue and disrupts the cells that support sperm production. Also impairs thyroid function, which amplifies testosterone suppression through the SHBG mechanism.
Found in: large predatory fish (tuna, swordfish, king mackerel), dental amalgam fillings, some freshwater fish
The Zinc Impersonator
Cadmium
Mimics zinc at the enzyme binding sites your body uses to make testosterone. Zinc is essential for testosterone production — so cadmium quietly stalls it, even when blood zinc looks normal.
Found in: cigarette smoke, some non-organic leafy vegetables, contaminated soil and water
The Fat-Storage Accelerator
BPA + Phthalates (metabolic effect)
Disrupt insulin signaling, driving visceral fat gain. Visceral fat is loaded with the enzyme that converts testosterone to estrogen. More belly fat → more conversion → lower testosterone → more fat. A self-reinforcing cycle with a chemical trigger.
The metabolic mechanism layered on top of the direct hormonal effects of bisphenols and phthalates
Where Is All This Stuff Hiding?
The short answer: everywhere you haven’t thought to look. Here are the highest-impact daily exposure points.
☕ Your morning coffee machine. If it uses plastic pods or internal plastic tubing, boiling water is running through phthalate-releasing plastic every morning. Switch to a glass or stainless steel French press — the single easiest swap with immediate impact.
🚰 Your tap water. PFAS contamination in U.S. municipal water is widespread. Lead from aging pipes is a separate concern — especially relevant in older Connecticut homes. Standard filters don’t remove PFAS. Reverse osmosis or distillation does.
🥫 Canned food. The epoxy lining inside cans is BPA- or BPS-based. This includes “healthy” canned fish, beans, and tomatoes. Glass jars or fresh/frozen are the alternatives.
🧴 Your grooming products. Phthalates are used to make fragrance last longer — and under FDA rules, “fragrance” on a label can mean hundreds of undisclosed chemicals. This includes body wash, shampoo, deodorant, and cologne. Switch to fragrance-free or check products on the EWG Skin Deep database.
🧾 Receipts. Thermal receipt paper is coated with BPA or BPS. Handling a receipt for 10 seconds — especially with wet or warm hands — delivers more BPA than an entire day of food packaging exposure. Decline receipts when you can.
👕 Your workout clothes. Stain-resistant and water-resistant athletic clothing is PFAS-treated. When you sweat during exercise, pores dilate and skin absorption increases — making the gym ironically a high PFAS exposure window.
🍳 Non-stick cookware. Scratched or overheated Teflon releases PFAS. Cast iron, stainless steel, and ceramic are safe. If the surface is damaged, replace it.
🥗 Non-organic produce. The EWG Dirty Dozen identifies the highest-pesticide fruits and vegetables each year. Strawberries, spinach, peaches, and apples consistently top the list. Full organic isn’t necessary — prioritize these.
Think your testosterone might have a chemical cause? At Restore Health in Fairfield, CT, I look at the full picture — environmental load, thyroid, metabolic function — before recommending any hormone therapy.

What to Actually Do About It
Two tracks: what you can start today without a doctor, and what requires clinical supervision. Both matter. Neither replaces the other.
Start Today — No Doctor Needed
🥦 Eat cruciferous vegetables daily. Broccoli, cauliflower, Brussels sprouts. They activate your liver’s detox enzymes and help clear excess estrogen — directly improving the testosterone-to-estrogen ratio.
🧖 Use a sauna regularly. Sweat is a real excretion route for BPA, phthalates, and heavy metals — confirmed in lab studies. Three to four sessions a week, 20–30 minutes. One of the most underrated testosterone support tools available.
🏋️ Lift weights. Resistance training directly stimulates testosterone production and activates antioxidant pathways that help your body manage chemical stress.
🚰 Install a reverse osmosis filter. Removes PFAS, lead, and chlorine byproducts at the source. The single highest-yield physical change a man can make to his daily environment.
🧴 Switch to fragrance-free grooming products. Measurably lowers urinary phthalate levels within days. No other lifestyle change works that fast.
🍱 Replace plastic food contact. Glass containers, stainless steel bottle, wooden cutting board, glass or stainless French press. Stop microwaving in plastic.
🌾 Take fiber seriously. Psyllium husk, ground flax, and oat bran bind toxins in the gut and prevent your body from reabsorbing them through what I call the “toxic loop” — where your liver processes a chemical, sends it to the gut via bile, and the gut reabsorbs it before it can exit.
😴 Protect your sleep. Most of your daily testosterone is produced during deep sleep. EDC-related hormone disruption makes this worse. Sleep hygiene is part of the protocol, not optional.
Clinical Protocols — Physician Supervised
EDTA chelation (IV). FDA-approved for lead poisoning. Binds lead, cadmium, and other metals for urinary excretion. The NIH TACT trial showed meaningful cardiovascular benefits in the right patients. At Restore Health, I only initiate this after documented testing — never as a generic “detox.” Essential minerals must be replaced throughout. Physician supervision required.
DMSA (oral chelation). For mercury and arsenic under clinical supervision. Crosses into the brain more readily than EDTA — preferred when neurological symptoms accompany high metals. Careful dosing and kidney monitoring required.
IV glutathione. Your body’s master antioxidant. Supports liver detox pathways. Most useful when testing shows oxidative stress alongside metal or solvent exposure.
Cholestyramine. A prescription bile binder that interrupts the toxic loop at a clinical level. Must be timed away from food and medications.
Testosterone therapy — when it’s actually indicated. If chemical burden has been addressed, thyroid is optimized, sleep is fixed, and testosterone is still low — then targeted hormone therapy is appropriate. I individualize every decision. For men who want to preserve fertility, I often prefer stimulating the body’s own production first. See my posts on low testosterone treatment and men’s hormone health for the full protocol.
Peptide therapy. Certain peptides support metabolic recovery alongside detox protocols. PT-141 addresses libido through brain pathways independently of testosterone levels — useful when desire is low even with adequate T. See my post on peptide therapy at Restore Health.
Clinical note on chelation: EDTA and DMSA are prescription-grade interventions, not supplements. At Restore Health, chelation is only initiated after documented testing showing elevated metals. The goal is precision, not generic detox. If you’ve been told your heavy metal levels are fine without a provoked urine metals panel or whole-blood metals test, you may not have the full picture.
The 5-Step Priority List: Start Here
If you take nothing else from this post, do these five things. In this order.
1. Test before you do anything else. A urine panel (Million Marker), a blood PFAS test (Quest, ~$250, no doctor needed), and a heavy metals panel give you actual data. Without it, every other step is guesswork. This costs less than three months of testosterone therapy.
2. Fix your water. Reverse osmosis removes PFAS, lead, and chlorine byproducts. The highest single-point exposure reduction available to most men — and a one-time installation.
3. Replace your coffee machine. If it uses pods or plastic parts, boiling water is running through phthalate-releasing plastic every morning. A glass or stainless steel French press costs $30 and lasts forever.
4. Go fragrance-free. Audit your grooming products using the EWG Skin Deep app. Fragrance-free deodorant, shampoo, and body wash measurably lower urinary phthalate levels within days. No other lifestyle change produces results that fast.
5. Add weekly sauna. If testing shows elevated BPA, phthalates, or heavy metals, sauna provides a documented excretion pathway no supplement can replicate. It also directly supports testosterone through heat-stress adaptation.
