Key Points

• Chemicals increasingly used to replace the toxic plastic additive bisphenol A (BPA) may disrupt fertility, fetal development, and reproductive health through many of the same biological mechanisms, according to a narrative review of human, animal and laboratory studies.
• Concerns about BPA have led some manufacturers to phase it out and replace it with structurally similar compounds, most commonly bisphenol S (BPS), bisphenol F (BPF) and bisphenol AF (BPAF). While BPA exposure has declined, BPS and BPF use is rising, especially in North America and Asia.
• These "cousin chemicals" or analogues were introduced without sufficient evidence of their safety, and subsequent studies show they have adverse effects similar to BPA, warranting more scientific and regulatory scrutiny. BPA has been associated with impaired memory and learning, infertility, heart disease, stroke, metabolic disease, type 2 diabetes, preeclampsia, obesity, and cancer, studies show.
• BPA is banned in baby bottles and sippy cups in both the European Union (EU) and in the United States because the chemical has been shown to leach from plastics into food or liquid.

Have you noticed friends or family members talking about how they, or someone they know is having a hard time getting pregnant? Or maybe they are struggling with hormonal issues? It's not just a coincidence. Exposure to some kinds of chemicals used in household products as well as pollution in our environment are linked to health impacts that can make it harder for women to concieve. Chemicals that mess with our body's ability to manage our hormones (also known as our endocrine system) are one of the culprits. These include groups of chemicals used in plastics and scented products like phthalates.

What you can do about it

In our homes, we try to select products that are made from materials that tend to be safer like glass, stainless steel, and wood while avoiding those made from plastic. We really focus on thes kinds of material choices for products that we use in the kitchen or that come into contact with food and beverages. We also look for companies that have products with higher-quality ingredient safety certifications and that are rated as "Recommended" or "Consider" by Hilde.
