How Everyday Chemicals Could Affect Women’s Hormones and Fertility

Growing evidence suggests everyday endocrine-disrupting chemicals deserve greater attention for their potential impact on women’s reproductive health.

Female reproductive health begins taking shape long before puberty and depends on healthy ‘hormonal signalling’ throughout life. A review published in Nature Reviews Endocrinology highlights growing evidence that exposure to endocrine-disrupting chemicals (EDCs) may contribute to a rise in female reproductive disorders by interfering with key stages of reproductive development and hormone regulation (1^✔ ✔Trusted Source

).
The review brings together findings from epidemiological and experimental studies to examine how these chemicals may affect the ovarian reserve, follicle development, and the hypothalamic-pituitary-ovarian (HPO) axis, which plays a central role in regulating puberty, ovulation, and fertility. At the same time, the authors note that proving direct causality between EDC exposure and reproductive disorders in humans remains challenging.

How Endocrine-Disrupting Chemicals May Affect Women’s Hormones

Endocrine-disrupting chemicals are substances that can interfere with the body’s natural hormone system. Common examples include bisphenol A (BPA), phthalates, certain pesticides, per- and polyfluoroalkyl substances (PFAS), and some flame retardants, although not every product contains these chemicals. They are found in various everyday products and environmental sources, such as certain plastics, food containers and packaging, cosmetics, pesticides and personal care products, making exposure common throughout life. Most people are exposed to low levels of multiple endocrine-disrupting chemicals through everyday life, making it difficult for researchers to study the effects of individual chemicals separately.According to the review, exposure to these chemicals may influence reproductive health by affecting:

• Formation of the ovarian reserve during early development
• Maintenance of healthy ovarian follicles during adulthood
• Hormonal signalling that regulates puberty and ovulation
• Neuroendocrine pathways involved in reproductive function

Rather than acting only during adulthood, the evidence suggests that exposure during early life may also influence reproductive health later in life. Researchers believe that fetal development, infancy, childhood, and puberty may represent particularly sensitive periods because the hormone system is still developing during these stages.

Evidence Links EDC Exposure to Female Reproductive Disorders

The review highlights epidemiological evidence linking exposure to endocrine-disrupting chemicals with several reproductive disorders, including:
Experimental studies in animals also demonstrate that exposure during early life as well as adulthood can negatively affect ovarian reserve, follicle development, and hormonal control of puberty and ovulation.

Researchers increasingly recognize that female reproductive health is influenced not only by genetics and lifestyle but also by environmental factors that may interact with the body’s hormone system throughout different stages of life.

Why Early Development Matters for Reproductive Health

A healthy ovarian reserve is established before birth and supports fertility during the reproductive years. Proper development of the hypothalamic-pituitary-ovarian axis is equally important because it coordinates hormone production and regulates menstrual cycles and ovulation.

A young girl entering puberty or a woman planning a pregnancy may never think about how early-life environmental exposures could influence reproductive health. The review suggests these developmental windows deserve greater attention when studying reproductive disorders.

Similarly, women experiencing irregular menstrual cycles or concerns about fertility may benefit from understanding that reproductive health is shaped by a combination of biological and environmental influences rather than a single factor.

Growing Evidence on Endocrine-Disrupting Chemicals and Women’s Hormones

Endocrine-disrupting chemicals may play a meaningful role in female reproductive disorders by influencing reproductive development and hormonal regulation across the lifespan.

At the same time, the authors emphasize important knowledge gaps, particularly in understanding how prenatal exposure may affect reproductive health later in life and across future generations. Establishing clear cause-and-effect relationships in humans remains an important scientific challenge.

Staying aware of how environmental factors interact with the body’s natural hormone system can help with informed conversations about women’s reproductive health.
