There is an increasing agreement that exposure to environmental toxins before conception can have negative impacts on fertility, pregnancy, and the development of fetuses, which may endure throughout infancy, adulthood, and potentially across multiple generations. In this article, we examine current information regarding exposure to various chemicals before conception and during pregnancy, such as heavy metals, substances that disrupt the endocrine system, pesticides, and air pollution. We explore the effects of these substances on obstetrical and reproductive health.
Reproductive endocrinologists and related healthcare providers have a distinctive opportunity to advise patients before they conceive about reducing exposure to harmful chemicals, aiming to enhance reproductive outcomes and promote overall well-being. We offer practical guidance and highlight publicly available resources for reproductive health professionals to evaluate a patient’s risks and recommend strategies for reducing exposure to chemicals and air pollution during the crucial preconception and prenatal periods.
Environmental factors play a crucial role in influencing women’s health, impacting well-being in various ways:
- Air Quality: The presence of pollutants like particulate matter, ozone, and toxic gases can result in respiratory problems and cardiovascular diseases, with potential exacerbation of pre-existing conditions such as asthma. Biological factors and hormone-related differences may render women more susceptible to these effects.
- Waterborne Diseases: Women, particularly during pregnancy and breastfeeding, face risks associated with waterborne diseases that can affect both maternal and child health.
- Chemical Exposure: Everyday exposure to chemicals, such as endocrine-disrupting chemicals (EDCs) found in plastics, pesticides, cosmetics, and personal care products, can disrupt hormonal balance. This interference may lead to reproductive issues, including infertility, menstrual problems, and certain cancers.
- Climate Change: The changing climate introduces diverse health impacts on women. Immediate risks include heatwaves, extreme weather events, and natural disasters, which can lead to heatstroke, injuries, and mental health issues. Long-term effects, such as altered disease patterns, food and water scarcity, and displacement, may disproportionately affect women due to societal roles, cultural factors, and limited resource access.
- Access to Healthcare: Environmental factors indirectly affect women’s health by influencing their access to healthcare services. Limited availability of clean water, sanitation facilities, and healthcare infrastructure can increase the risks of infections, pregnancy complications, and insufficient maternal and child healthcare.
Raising awareness about the intersection of environmental factors and women’s health is essential for driving meaningful change and promoting overall well-being.

How Environmental Toxins Harm Women’s Reproductive Health
Two prominent organizations in reproductive health, the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine, jointly issued a committee opinion highlighting the detrimental impact of environmental toxins on women’s fertility.
Dr. Linda Giudice, President of the American Society for Reproductive Medicine, emphasized that mounting evidence over the past five to seven years indicates that environmental contaminants can significantly harm reproductive health. With more than 7,000 health professionals and researchers in its network, the organization underscores the urgency of addressing this issue.
Giudice expressed hope that increased awareness among patients and healthcare communities regarding the harmful and potentially enduring effects of environmental exposures on reproductive health could lead to their avoidance or minimization.
She emphasized the importance of prevention in reproductive environmental health, as toxic agents have the potential to affect future generations through transmission.
The committee conducted a thorough review of scientific evidence on toxins over two years to formulate their opinion, which not only delineates environmental health concerns but also proposes action at individual, healthcare professional, and governmental levels.
The committee’s opinion will be published in the October issues of the journals Fertility and Sterility and Obstetrics and Gynecology.
Calls to action
Dr. Jeanne Conry, President of The American College of Obstetricians and Gynecologists, emphasized the heightened vulnerability of pregnancy to environmental exposures, highlighting the need for caution among women during this critical period. Representing approximately 57,000 physicians, Conry underscored the concerning proliferation of chemical substances, with over 84,000 currently utilized in manufacturing or processing, and approximately 700 new chemicals introduced annually in the United States.
She noted a troubling trend of increasing disease processes, including birth defects, autism, and breast cancer rates, against a backdrop where genetic factors remain relatively unchanged over the past few decades. Conry suggested that these rising rates are likely attributable to environmental factors.
Conry expressed concerns regarding the insufficient research conducted on the health effects of many chemicals before their release into the environment. Given that these chemicals pervade the air, water, soil, food, and consumer products, limiting exposure proves challenging for individuals. Moreover, certain groups, such as those working in environments with elevated pesticide or industrial chemical exposure, or residing in areas with heightened air pollution or indoor contaminants like lead, face greater vulnerability to these toxic risks.
Minimizing exposures
Furthermore, chemicals such as mercury, sourced from fish consumption, have the ability to pass through the placenta and accumulate in the developing fetus. Dr. Conry highlighted that researchers have long understood the behavioral impacts of mercury on children.
To mitigate risks, women who are contemplating pregnancy, pregnant, or breastfeeding should steer clear of fish varieties high in mercury content, including shark, swordfish, tilefish, and king mackerel. Instead, they should opt for seafood with lower mercury levels.
Additionally, women in these categories should wash fresh fruits and vegetables before consumption to minimize exposure to pesticides, which have been associated with an elevated risk of childhood cancers.
By scrutinizing product labels, women can also make informed decisions to avoid Bisphenol A (BPA), a prevalent hormone disruptor found in the plastic lining of certain canned foods and numerous household items.
Dr. Conry stressed the importance of promoting consumer awareness without inducing undue alarm.
The committee’s opinion paper further urged healthcare professionals to inquire about environmental exposure history during preconception consultations or initial prenatal appointments. This questionnaire would empower doctors and nurses to educate women on strategies for minimizing exposure to toxins in their homes, workplaces, or communities.
Dr. Giudice emphasized the potential for raising awareness to diminish environmental exposure while enhancing reproductive health, asserting it as a significant objective.
Conclusion
In conclusion, environmental exposure poses significant risks to women’s health across various stages of life, particularly during pregnancy and breastfeeding. Chemical pollutants, such as those found in air, water, soil, and consumer products, can disrupt hormonal balance, increase the likelihood of reproductive issues, and contribute to adverse health outcomes in both women and their offspring.
Moreover, substances like mercury from certain fish and pesticides on fruits and vegetables can cross the placenta, affecting fetal development and potentially leading to long-term behavioral and health challenges in children.
Through heightened awareness, proactive measures, and informed decision-making, women can mitigate exposure to harmful environmental toxins. This includes adopting dietary guidelines that minimize consumption of mercury-rich fish, washing produce to reduce pesticide exposure, and selecting products free of hormone-disrupting chemicals like Bisphenol A.
Healthcare professionals play a crucial role in educating women about environmental risks and empowering them to make informed choices to safeguard their reproductive health and that of future generations. By integrating environmental exposure assessments into preconception and prenatal care, healthcare providers can contribute to minimizing risks and optimizing reproductive outcomes.
In essence, addressing the impact of environmental exposure on women’s health requires collaborative efforts among individuals, healthcare professionals, policymakers, and communities. By prioritizing prevention, promoting awareness, and advocating for policies that prioritize environmental health, we can strive towards ensuring a healthier and more sustainable future for women worldwide.
