A fertility doctor is telling patients that common household items like plastic containers and scented candles may be quietly messing with their hormones.
Quick Take
- Dr. Natalie Crawford, a double board-certified reproductive endocrinologist, recommends eight household swaps to cut exposure to hormone-disrupting chemicals.
- Scientific reviews confirm these chemicals, found in plastics, canned food, and personal care products, can interfere with the body’s hormone system.
- Research shows cutting exposure is possible, but proof that it improves fertility or health outcomes is still limited.
- Experts warn some “safer” replacement chemicals may carry similar risks to the ones they replace.
A Fertility Doctor’s Case For Household Swaps
Natalie Crawford, MD, practices as a double board-certified reproductive endocrinologist in Austin, Texas. She trained in reproductive endocrinology and infertility at the University of North Carolina and holds a master’s degree in clinical research. Her credentials give her advice on hormone health real medical weight, especially when she tells patients that small changes at home might lower their exposure to chemicals linked to fertility problems.
Crawford’s video lays out eight specific swaps, including ditching plastic food containers, canned goods, and certain personal care products. These are not random tips. They match patterns found across years of scientific study into how everyday chemicals interact with the body’s hormone systems.
What The Science Says About These Chemicals
Endocrine-disrupting chemicals are substances that get in the way of the body’s natural hormones. They can copy or block hormones like estrogen, testosterone, and thyroid hormone. A 2025 review of a decade’s worth of human studies found real links between these chemicals and fertility problems, giving scientific backing to Crawford’s warnings.
A committee opinion from the International Federation of Gynecology and Obstetrics states that chemicals such as PFAS and phthalates can hurt testosterone production and lower sperm quality in men. These chemicals show up in plastics, nonstick cookware, and some cosmetics. That is why swapping out these products at home lines up with what major medical groups have flagged as a concern.
Do The Swaps Actually Help?
Here is where the evidence gets murkier. A review of 13 intervention studies found that 12 of them involved diet changes or swapping household and personal products. But the results on whether these changes actually improved health were inconsistent. Reducing exposure is measurable. Whether that reduction leads to better hormone or fertility outcomes is still an open question researchers have not fully answered.
Other reviews back up specific swaps Crawford recommends. One study found that avoiding plastic containers, canned food, and processed food, while eating fresh or organic food, effectively lowered chemical exposure. Vitamin C and iodine supplements also showed up as possible tools to offset some chemical effects, according to the same research.
A Catch With “Safer” Replacements
Not every swap is a clear win. The Endocrine Society has warned that some replacement chemicals, like BPF and BPS used instead of BPA in plastics, can cause similar hormone problems as the originals. Scientists call these “regrettable substitutions,” where a company swaps one risky chemical for another that has not been studied enough to know if it is actually safer.
This is the hidden trap for consumers trying to do the right thing. A label that says “BPA-free” does not always mean a product is free of hormone-disrupting chemicals. Researchers say chemicals in the same class often carry similar risks, even with different names on the packaging.
Why This Resonates With Everyday Families
This story taps into a wider frustration many Americans share. People feel they cannot fully trust that products on store shelves are safe, no matter what the label claims. Whether the worry is over food ingredients, water quality, or plastic packaging, the pattern is the same: official safety approval does not always match what independent research later finds.
Crawford’s eight swaps give families a practical, low-cost way to act now, without waiting on regulators or new studies. That kind of self-reliance is exactly why her advice has found an audience among people who want results they can control, right in their own kitchens and bathrooms.
