Climate change is making fertility, human and otherwise, much more precarious. Climate factors that play a vital role in reproductive health include rising temperatures, extreme weather events, and environmental pollution.

In fact, studies have demonstrated that heat stress can negatively impact sperm quality in humans. On top of this, air pollution and chemical exposure can affect hormonal balance in men and women.

Just as with human species, wildlife species are changing their reproductive behavior, with some unable to keep pace with their environment’s transformation. These changes have big implications for future food security, population growth, and our biodiversity.

Knowing how climate change affects fertility is important. Only by doing so can we effectively address these challenges and find meaningful ways to reduce its impact.

Use the pages below to learn more about these important issues and learn how you can take practical action to reduce these risks.

Climate Change: A Global Threat

Climate change presents a formidable threat to worldwide health, especially reproductive health. Increased heat exposure, changing weather patterns, and decreasing natural environments all have clear effects on fertility and birth outcomes. Future projections indicate that summer temperatures at 5° latitude may increase by 10% by the year 2100. This massive increase will disrupt agricultural cycles and compound threats to food security.

This disruption has a direct and unequivocally harmful effect on reproductive health. Especially during high stress periods, such as during the harvest, malnutrition and physical exertion can lead individuals to switch their family planning practices.

Air pollution and heat stress negatively affect reproductive health and birth outcomes. In fact, they are linked to major health outcomes such as preterm birth and low birthweight. In areas where strong mitigation policies are not implemented, the increase in temperature could be as high as 3.3% above baseline. This increase will significantly escalate the related dangers.

People least able to adapt, particularly pregnant women in developing countries, are suffering the impacts of these developments. Barriers to healthcare and healthy nutrition only heighten the effect, leading to lifelong health issues for mothers and babies alike. Spatial data, national data offset by 3-6 miles for confidentiality, have revealed how localized conditions further strain these communities.

As for the future, the damage to future generations is egregious. Climate models indicate a 15% decrease in skilled-to-unskilled ratios, indicating diminished prospects for children born under these circumstances. The need to rethink fertility transitions with demographic and geographic frameworks has recently become urgent.

The relationship between fertility, reproduction, and climate remains poorly understood especially in many low-income countries. This major gap in knowledge highlights an immediate need for more research.

How Does Climate Change Affect Fertility?

Climate change presents enormous stressors on fertility health, particularly for postpartum women, from changing biological processes to impacting environmental conditions that play instrumental roles in human reproduction. From increased temperatures to heightened air pollution, the effects on prenatal health are complex and interconnected, making it essential to understand their implications.

1. Rising Temperatures and Sperm Health

Increased temperatures have been shown to affect sperm production and mobility, directly affecting male fertility. Research shows that a 1°F rise in summer temperature can lead to fewer births nine months later in many U.S. States.

We know from the effects of prolonged heat exposure that sperm quality is diminished and even long-term reproductive effects are possible. For instance, research has shown that increased temperatures interfere with normal testicular function, leading to reduced sperm count and motility.

The urgent need to monitor temperature trends is necessary to mitigate these risks, especially as heatwaves continue to increase in intensity and frequency.

2. Air Pollution’s Impact on Egg Quality

Increased air pollution has been shown to adversely impact ovarian function and egg quality. Women’s fertility is adversely affected by exposure to PM 2.5.

Research has found that increased air pollution results in decreased reproductive success. This is especially alarming in major metropolitan cities where air quality already exceeds safety standards.

Stronger reproductive health protections against air pollution are critically needed.

3. Endocrine Disruptors and Hormonal Imbalance

Endocrine disruptors, which include common pesticides and prevalent plastics, disrupt hormonal balance, making conception and maintaining a pregnancy more difficult.

These disruptors are everywhere in today’s environments, highlighting the urgent policy imperative to restrict exposure to harmful chemicals to protect fertility.

4. Extreme Weather and Pregnancy Complications

Extreme weather events add considerable stress and danger to the health of pregnant people, resulting in higher rates of complications including preterm births.

To meet these risks, climate disaster preparedness and mental health care is essential.

Specific Climate Factors and Reproduction

Environmental factors have always played a role in reproductive health, but climate change is creating new threats to global reproductive health. Temperature extremes and high temperatures have extreme and widespread implications for postpartum women and fertility. For males, they lower sperm counts and sperm motility. Recognizing these relationships will allow us to educate communities about the wider impact climate change has on population health.

Temperature Extremes: Male Fertility

Long-term exposure to extreme heat leads to detrimental effects on male reproduction. Heat stress, for example, can lead to increased mortality and defects in sperm, complicating conception. Research suggests that repeated exposure to temperatures greater than 90°F is seen to negatively impact testicular function and fertility potential.

Seasonal temperature fluctuations exacerbate this problem, with decreases in fertility reported in the summer months. Educating the public, especially those experiencing male infertility, about the role of temperature in male fertility is crucial, particularly as global temperatures increase. Employers and their workers in sweltering climates stand to gain from protective measures that reduce heat exposure.

Air Quality: Female Fertility

Specifically, women’s reproductive health is impacted by poor air quality. Higher exposure to endocrine disruptors and pollutants such as fine particulate matter (PM2.5) disturb endocrine homeostasis and ovarian activities. Studies have found that women who live in more polluted neighborhoods have a harder time getting pregnant.

Protecting clean air through measures like the Clean Car Standards and curtailing industrial emissions are vital for addressing and protecting reproductive health. More long-term controlled studies are needed to uncover the full extent of air quality’s impact on female reproduction.

Water Scarcity: Nutritional Impacts

Nutritional health is central for fertility and healthy pregnancies, and water stress has direct implications on nutritional health. When access to clean water is limited, food availability, including nutrient-rich foods, decreases, increasing the burden on reproductive health.

For instance, dehydration and malnutrition can contribute to issues such as missed or irregular menstrual cycles or low sperm count. More sustainable water management policies are clearly needed, both to protect people’s nutrition and their fertility.

Vulnerable Populations and Disparities

Climate change exacerbates the inequities that already exist, specifically harming lower-income, marginalized populations, and people of color. Vulnerable populations including low-income families, rural families, and communities of color face compounded burdens.

These barriers severely affect their ability to conceive and their reproductive health. The Intergovernmental Panel on Climate Change (IPCC) underscores the plight of socially vulnerable peoples. Those who face both the impacts of pollution and urban heat, or who live in communities with fewer resources for climate adaptation, face increased harms.

These disparities highlight the urgent need for targeted action.

Socioeconomic Factors Worsen Impacts

These economic hardships exacerbate existing reproductive health disparities. People of lower socioeconomic status are at great risk for adverse health effects because they may have less access to healthcare and transportation resources.

Consider that 46 million rural Americans face the double burden of uninsurance. This puts up a lot more barriers to them seeking reproductive care. Climate change exacerbates economic instability through events such as droughts, which can push back marriage or lower the likelihood of conception, shifting patterns of fertility.

Addressing these disparities means enacting policy reforms that improve access to affordable healthcare, invest in climate adaptation programs, and provide financial assistance to our most underserved communities.

Geographical Disparities in Fertility

We know that geographical location has a huge impact on fertility outcomes. In sub-Saharan Africa, although high fertility rates have declined with mortality, this is due to a lack of access to healthcare and cultural norms.

Adverse climate conditions such as failing rainy seasons can alter reproductive schedules by postponing marital age or spacing births longer. Targeted, region-specific strategies, whether that be supporting the resilience of agricultural communities or provisioning reproductive health services to demographic communities, are key to reducing these disparities.

Further research into these geographical trends is imperative for developing solutions that work.

Healthcare Access and Climate Change

Environmental changes further tax already strained healthcare systems. In addition, disruption of reproductive health services through rising temperatures, extreme weather, and pollution may worsen existing disparities, particularly in low-resource communities.

It’s especially important to strengthen healthcare infrastructure in our most vulnerable communities. Equitable access to care is especially important now. By engaging rural health programs in the difficult work of addressing these challenges, we can protect the reproductive health impacts of climate change.

Long-Term Reproductive Health Effects

Climate change impacts on reproductive health go beyond the present, affecting generations before and after us. Rising temperatures and more extreme weather exacerbated by climate change are putting a growing negative impact on fertility and pregnancy outcomes.

Moreover, environmental toxins are threatening the long-term health of future generations. For example, women engaging in intense outdoor labor during hot periods report physical and psychological stress, fearing miscarriage or complications at birth. Seasonal changes impact pregnancy outcomes as well, with workload, diet, and overall fertility having major influences.

Generational Impacts of Climate Change

Climate change adds an array of new environmental stressors with generational impacts, jeopardizing reproductive health in the here and now as well as for the coming decades. Communities where women divide their labor between cooler and hotter parts of the day illustrate how environmental pressures influence fertility decisions.

Some avoid pregnancy during peak farming seasons due to physical demands, while others face risks tied to cultural norms or economic activities, like collecting and selling resources. Policies that counter these intergenerational harms are critical to advancing reproductive health, rights, and justice in an increasingly hot planet.

Research on Climate and Fertility

Interdisciplinary, policy-relevant research is needed to understand climate change’s indirect effects on fertility. By 2050, today’s infants will need to navigate reproductive health challenges in an environment that is much more likely to be dangerously hot.

In order to find these solutions, funding for studies that can help bridge environmental science and reproductive health is crucial. Multidisciplinary collaboration guarantees that all aspects of these complex problems are considered.

Environmental Toxins and Fertility

Toxins, such as pesticides and environmental pollutants, directly reduce fertility in postpartum women and create poor pregnancy outcomes. By regulating these harmful substances and raising public awareness, we can avoid significant risks and protect our future generations.

Mitigating Climate Change’s Impact

Mitigating climate change’s impact is a shared responsibility that rests on the shoulders of citizens, communities, and leaders. Its profound effects on health—including on postpartum women and fertility—necessitate aggressive efforts to limit exposure and strengthen resilience. Through understanding the importance of collective action, adoption of sustainable practices, and the need for individual responsibility, we can create a healthier tomorrow.

Advocate for Climate Action

Mobilizing communities to push for local and state-level, climate-friendly policies will be key. Grassroots movements like these have brought about change, frequently pressuring lawmakers to pass legislation that mitigates environmental dangers at their source.

For example, campaign efforts to advance clean energy have decreased air pollution in cities, leading to healthier, more vibrant environments for families. Participating in local efforts such as public hearings or funding groups working on the frontlines of climate justice issues can help raise your voice.

Advocacy plays a crucial role in shaping a future where health, including reproductive health, is less threatened by environmental factors.

Support Sustainable Practices

Sustainable living is an easy way to mitigate the impact of climate change. Every little bit helps.

Simple, everyday actions such as composting, using reusable products or platforms that connect with local farmers can minimize waste and save valuable resources. In addition, sustainable agriculture decreases use of harmful chemicals, improving soil and water quality.

Community-led projects, like the urban gardens pictured below, help foster healthier diets while improving social cohesion. These efforts to help mitigate climate change’s impact on reproductive health aren’t just good for the environment—it promotes healthier communities, including improving fertility.

Reduce Your Carbon Footprint

Reducing actions that emit carbon truly makes a difference. Whether through making the switch to energy efficient appliances, using public transit or taking part in tree-planting initiatives, these actions help cut greenhouse gases and protect air quality.

Cleaner air means fewer people suffering from respiratory conditions, leading to improved reproductive health indirectly. Local programs can provide direct incentives, like tax rebates for residential solar panel installations, that put sustainable choices within reach.

Adaptive Strategies and Interventions

Understanding climate change is impacting reproductive health, particularly for postpartum women. Adaptive strategies and interventions should focus on resilience, sustainability, and inclusivity from their inception to lessen the negative effects on fertility and overall health outcomes for future generations.

Improve Healthcare Infrastructure

Strengthening our healthcare infrastructure, proactively making it more resilient to climate-related disruptions, must be a priority. Robust systems equipped to handle extreme weather events, such as hurricanes or heatwaves, can maintain access to reproductive health services.

Emergency preparedness plans should be in place. They should have backup power for critical facilities, as well as provision for mobile clinics to be deployed for continuity of care during disasters.

Investments in green infrastructure, which reduce environmental impacts while improving community resilience, offer benefits like economic growth and enhanced livability. Switching to reusable medical equipment such as stainless steel specula reduces GHG emissions by roughly 75%. This practice reduces the amount of waste produced.

Develop Climate-Resilient Agriculture

Food security, essential to reproductive justice ideals, is fundamental to reproductive health. Climate-resilient agricultural practices such as crop diversification and soil conservation are crucial to maintaining stable access to healthy food.

Providing this assistance results in healthier pregnancies and lessens the risk of malnutrition. Sustainable agriculture reduces soil erosion, pollution, and salinization, thereby maintaining fertility in an indirect way.

Policies geared towards these adaptive strategies and interventions are key to establishing lasting resilience.

Promote Family Planning Access

Expanding accessible, quality family planning services empower people with the tools to navigate reproductive health in an increasingly climate-challenged world. Robust educational initiatives can mitigate the impact of climate-induced stressors on fertility and promote reproductive autonomy and informed family planning.

Healthcare providers and climate advocates alike can collaborate to boost these efforts. Together, they can make sure that the most vulnerable populations are given deep access and assistance.

Innovative Healthcare Policies

Climate change is the greatest and most urgent challenge to global health today, particularly impacting postpartum women and their reproductive health. In order to address these challenges, we need bold and innovative reproductive healthcare policies that consider the effects of high temperatures on prenatal health. Aligning climate action with healthcare systems increases sustainability and enhances overall health outcomes.

Integrating Climate into Reproductive Care

Making climate awareness a core component of reproductive healthcare is imperative. Given that extreme heat and pollution have direct, negative effects on fertility outcomes, such integration is imperative. When healthcare providers are trained on these risks, they are best equipped to guide patients through the choices available to them.

Teaching individuals how air quality can impact pregnancy will help them take control of their health. This information enables people to make informed decisions about when and how many children to have. Creating regulations that focus on the environment, like regulating exposure to extreme heat or the safety of drinking water, further composes the web of reproductive care.

That’s why it’s critical to have reproductive health experts work hand in hand with environmental researchers to bring reproductive health practices in line with sustainable, healthy goals.

Funding Climate-Fertility Research

Greater investments into climate-fertility research are needed to comprehend the long-term impacts of these environmental changes on our reproductive health. Interdisciplinary studies bridging medical, environmental and social sciences can shed light on complicated links like how increasing temperatures affect hormonal health.

This is a critical moment, and we encourage Rebuild priorities to drive bold innovations in reproductive medicine. As just one example, research on impacts of air pollution on outcomes from in vitro fertilization could inform future healthcare policies and practice.

Public Health Initiatives

To be effective, public health initiatives that tackle the intersections between climate and reproductive health should center communities and their needs. Campaigns that promote eco-friendly healthcare practices, such as recycling medical waste, show tangible results.

For example, recycling programs in surgical units have reduced waste by 50-67%, proving that even small steps can contribute to climate resilience. Sustained investment in these kinds of programs is what brings long-term benefits to communities and ecosystems alike.

Conclusion

The impacts of climate change go beyond the physical environment, extending deep into personal and societal health—fertility included. Increasing temperatures, pollution, and more frequent extreme weather events pose new, intersecting challenges for reproductive health and justice, which require urgent action. Other communities are at an increased risk, underscoring the importance of tailored solutions and equitable access to health care.
