Plastics and Hormones: A Hidden Link
When you enjoy hot takeaway from a hawker center or microwave a ready meal in a plastic container, you might be consuming chemicals that could affect your fertility. Heat can release bisphenol A (BPA), phthalates, and PFAS from plastics. These are endocrine disrupting compounds (EDCs) that interfere with hormone function.
Common Sources of EDCs
Common sources include takeout containers, cling wrap, pizza boxes, and popcorn bags (with PFAS grease-proof linings). Unexpected sources include thermal receipts, household dust, and certain personal care products.
Impact on Female Fertility
Studies link EDC exposure to premature ovarian insufficiency, polycystic ovary syndrome, reduced egg number and quality during IVF, and poor embryo quality. Male exposure may also lower sperm count or motility, affecting IVF success.
Singapore Study
A local study found that women with higher PFAS levels in their blood had lower chances of pregnancy. PFAS are known as “forever chemicals” because they persist in the environment and human body.
How to Reduce Exposure
- Avoid heating food in plastic containers; use glass or ceramic instead
- Reduce use of disposable plastic utensils and bags
- Choose fresh over processed foods
- Clean indoor dust regularly to reduce microplastic inhalation
- Wash hands after handling thermal receipts
