Limiting Endocrine Disrupting Chemicals – Why It Matters for Fertility, Endometriosis, and PCOS
Kristy Wiseman - APD
When you're trying to conceive, or managing a condition like endometriosis or PCOS, nutrition and lifestyle choices matter more than ever. But there's one area that often gets overlooked, and that’s exposure to endocrine disrupting chemicals (EDCs).
These are chemicals that interfere with the function of our body’s hormonal system. EDCs can mimic, block, or alter our natural hormones—especially oestrogen—which can have significant effects on reproductive health and hormone-related conditions.
How EDCs Impact Fertility, Endometriosis & PCOS
Research has linked EDC exposure to:
Reduced egg and sperm quality
Irregular menstrual cycles
Hormonal imbalances and impaired ovulation
Increased inflammation (a key driver of endometriosis and PCOS)
Increased risk of miscarriage or IVF failure
For those with PCOS, EDCs may worsen insulin resistance and androgen excess. In endometriosis, they may fuel inflammation and hormonal dysregulation, contributing to symptom flares and disease progression.
Common Sources of EDCs:
Bisphenol A (BPA) – found in plastics and food packaging
Phthalates – in personal care products and soft plastics
Parabens – used as preservatives in cosmetics and skincare
Pesticides – found on non-organic produce
Dioxins – released from industrial processes
Simple Swaps to Reduce Your Exposure
We’re exposed to EDC’s in the air we breathe, the water we drink, the personal care products, plastic containers, and household items we use, and especially through the foods we eat.
But, the good news is, we can reduce our exposure to EDCs through some simple everyday swaps:
Use a stainless steel or glass drink bottle instead of plastic
Avoid microwaving food in plastic containers
Choose fresh or frozen produce over canned (many cans are lined with BPA)
Switch to fragrance-free personal care products
Look for “BPA-free” and “phthalate-free” labels
Wash fruits and veggies thoroughly, or buy organic when possible
Use natural cleaning products or make your own
Minimising your exposure to EDCs is one piece of the puzzle when it comes to supporting fertility and managing hormonal conditions like endometriosis and PCOS.
If you're trying to conceive or living with a reproductive health condition, taking a closer look at your environment can be just as important as what's on your plate. And, even small changes can lower your body’s chemical burden and support your hormone balance and fertility.
