The Fabric of Fertility: How Polyester and BPA Are Disrupting Women's Hormones with Dr. Jeffrey Brown
I’ve spent years exploring the intersection of fashion and sustainability with ReFashion Workshop, but this conversation with Dr. Jeffrey Brown cracked something open for me that goes way beyond eco-consciousness. It’s personal. It’s about your body. And it’s about the chemicals hiding in your favorite leggings.If you’ve ever wondered why more women than ever are struggling with infertility, painful periods, or hormonal chaos, and why your conventional doctor keeps handing you birth control instead of answers, this episode is for you. Dr. Brown, a functional medicine physician who’s spent over 15 years helping women reclaim their fertility after conventional medicine told them surgery was their only option, pulled on a thread most of us have never even noticed: the polyester hanging in our closets.The Thread We Need to PullHere’s what most people don’t realize: the polyester in our closets is often processed along plastics containing BPA, a chemical directly linked to hormone disruption and fertility struggles. We talk about diet. We talk about stress. We talk about sleep. But how often does your doctor ask about the synthetic fabrics touching your skin every single day?“When it comes to environmental exposures,” Dr. Brown told me, “it’s one of the hallmarks of healing and helping hormones to rebalance itself.”One month of his six-month program for women with endometriosis and adenomyosis is devoted entirely to detoxification, understanding toxins, improving your body’s ability to get rid of them, and learning how to eliminate those exposures altogether. Because here’s the thing: if we don’t tackle the source of the problem, the hormones won’t reestablish balance.The Big Three Endocrine DisruptorsLet me introduce you to the chemicals you’ve probably never heard of but are definitely carrying in your body right now:BPA, PFAs, and phthalates.These are the heavy hitters. And they’re everywhere—especially in the clothing industry.Dr. Brown explained it better than I could: “These chemicals interfere with the body’s chemical messengers. Hormones are the body’s way of delivering messages, right? They’re signals. And these chemicals get in the way of those messages.”Think of it like this: your hormones are trying to have a conversation with your body, and these chemicals are just creating noise—misdirection, interference, chaos.When your hypothalamus (the control center of your entire hormonal system) tries to send signals for estrogen production, but BPA is already pretending to be estrogen? Your body doesn’t produce the hormones it actually needs. Your ovulation gets disrupted. Your progesterone drops. And suddenly you’re living in an estrogen-dominant state with all the painful cramps, irregular periods, and PMS symptoms that come with it.“It disrupts the whole hormonal cascade,” Dr. Brown said. “Too many women are suffering because of these chemicals, and they’re just disrupting the body’s way of communicating with itself.”We’re Literally Passing This to Our ChildrenThis is the part that kept me up at night.Studies have found over 100 chemicals in fetal cord blood. Children are being exposed to endocrine-disrupting chemicals in the womb. And one theory about why endometriosis rates are skyrocketing? Fetal exposure to these chemicals is affecting genetic expression and hormonal development before a girl even gets her first period.Dr. Brown shared something sobering: “You start seeing childhood cancers, all these things we know are contributing to these chemicals. Cancer is an adult disease as you age. It shouldn’t be in children.”The chemicals are changing our DNA. They’re affecting genetic expression. And the kicker? Fertility rates are declining at an alarming rate—we’re seeing about a 40% decline in fertility based on chemical involvement alone.The Microplastics Problem (And How They Work)Here’s where it gets really interesting. Microplastics aren’t just floating around doing nothing. They’re carriers. They attract and hold onto these endocrine disruptors, traveling through your body and storing themselves in your organs and tissues.“We’ve tested every bodily fluid you can think of,” Dr. Brown told me. “Stool, urine, semen, blood—microplastics are everywhere. And here’s the problem: it’s extremely challenging for your body to get rid of them.”The microplastics themselves already contain BPAs and phthalates because that’s literally what they’re made from. The BPA makes the plastic rigid. The phthalates make it flexible. So when that plastic breaks down into microplastics, those chemicals come with it.And they’re storing themselves in our tissues. They’re wreaking havoc on our hormonal systems. And our bodies don’t have an easy way to get rid of them.But Here’s the Good News (Yes, There Is Some)Dr. Brown doesn’t believe in doom and gloom—he believes in optimization. And that’s actually empowering.You can’t necessarily break down the “forever chemicals” already in your body. But you can help your liver, kidneys, and GI system work more efficiently. You can support your body’s natural detoxification pathways. You can reduce inflammation. You can stop introducing new toxins.“Our bodies are wonderfully made,” he said. “We just need to help them work more efficiently. Too many of these chemicals and habits interfere with that efficiency.”His detoxification protocol focuses on:* Supporting liver and kidney function through targeted nutrition* Improving gut health (do you know how many women are chronically constipated? When you’re not having regular bowel movements, you’re just reabsorbing those toxins)* Reducing inflammation by cutting out processed foods and the SAD diet* Eating cleaner and making intentional choices about what touches your bodyAnd the results? People see a difference. Energy improves. Brain fog lifts. Pain decreases.The Practical Changes You Can Actually MakeHere’s what I love about Dr. Brown’s approach: he doesn’t want you to stress yourself into financial ruin trying to overhaul your entire life.Instead, he recommends incremental change:The next time you’re shopping, make one healthier choice.Buy one organic cotton t-shirt instead of polyester. Switch one plastic food container to glass. Replace one synthetic sports bra with a natural fiber option. That’s it. One item at a time.Before you know it, you’ve replaced your entire wardrobe without the financial or emotional stress of trying to do it all at once.Dr. Brown’s hierarchy of change makes sense:* Start with diet. Cut out processed foods. Reduce inflammation.* Then household items. Glass containers instead of plastic. Stop heating food in plastic.* Then clothing. Natural fibers, especially for things touching your skin all day (looking at you, yoga pants).* Then cosmetics and cleaning products. One at a time.And here’s the thing: if it stresses you out, it defeats the purpose. Stress is another toxin. So go slow. Go steady. Go with intention.California Just Changed the GameI have to mention this because it’s huge: California passed a law two years ago requiring clothing companies to test their apparel for chemicals.Last month, Nike, Adidas, Fabletics, and Lululemon all had their workout clothes tested. 100% of their products tested at 40 times the safe level of BPA.They’re getting sued. And they’re going to be forced to change.Until we have better federal regulation, the courts are where these battles get won. But this is a massive shift. The system might be set up to let corporations get the green light quickly, but we have the power to hold them accountable.What Dr. Brown Would Change About Women’s HealthcareIf he could redesign one thing about women’s health, it would be this: reverse the burden of proof.Right now, in America, chemicals have to be proven unsafe before they’re pulled from the market. Other countries do the opposite, chemicals have to be proven safe before they’re allowed.Think about the difference: We’ve been using chemicals for years that are causing cancer, infertility, and ho… Get full access to ReFashion Workshop at courtneybarriger.substack.com/subscribe
