Conversations about fertility are evolving.

While age, hormones, and medical history remain central, there is growing awareness of another important factor: environmental toxic chemical exposure.

The Netflix documentary The Plastic Detox brings this topic into a more visible, mainstream conversation and highlights how everyday exposure to environmental toxic chemicals may intersect with reproductive health.

The documentary reflects what we are increasingly seeing in both clinical practice and research: fertility is influenced by factors beyond what happens inside the body alone, and many of these exposures are modifiable.

Why environmental exposures are part of the fertility conversation

Infertility rates have increased over time, though the causes are complex and nuanced. 

In addition to known medical factors, a growing body of research has found associations between environmental toxic chemical exposures and reproductive health outcomes. Microplastics, for example, have now been detected in reproductive tissues and are being studied for their role in hormone disruption, inflammation, and fertility.

Studies have also shown that higher exposure to certain endocrine-disrupting chemicals, such as BPA, is associated with poorer outcomes in patients undergoing IVF, including effects on egg quality and embryo development.

This is the conversation that The Plastic Detox explores: how modern, everyday toxic chemical exposures may contribute to broader health patterns, including fertility.

What the documentary shows about everyday chemical exposure

One of the key takeaways from The Plastic Detox is how common and often invisible environmental exposures are.

These exposures can come from:

• Food packaging and storage
• Plastics used in food and beverage containers
• Personal care products
• Household items and cleaning products

They are not always obvious, and in many cases, they are part of daily routines.

The documentary highlights an important concept: it is not one single exposure, but the cumulative effect of many small exposures over time that matters.

Endocrine-disrupting chemicals and reproductive health

Many of the chemicals discussed in The Plastic Detox fall into the category of endocrine-disrupting chemicals (EDCs).

EDCs are substances that can interfere with the body’s hormone systems.

Common examples include:

• BPA (bisphenol A)
• Phthalates
• Certain pesticides and industrial chemicals

Hormones play a central role in fertility, regulating ovulation, sperm production, and the menstrual cycle.

Disruption in hormone signaling has been linked to altered reproductive function, including changes in ovulation, sperm quality, and overall fertility outcomes, as demonstrated across multiple studies.

How environmental exposures may impact fertility

Research shows that environmental exposures may influence fertility in several ways.

These include:

• Effects on egg quality
• Impacts on sperm health and motility
• Changes in hormone regulation

In patients undergoing fertility treatment, higher levels of certain environmental chemicals have been associated with lower IVF success rates and changes in embryo development.

There is also increasing evidence linking environmental exposures to inflammation and oxidative stress, both of which are known to play a role in reproductive health.

Practical ways to reduce exposure (without overwhelm)

A key message, both from The Plastic Detox and from clinical practice, is that small, consistent changes can make a difference over time.

This does not require perfection.

Some practical starting points include:

• Using glass or stainless steel instead of plastic for food storage
• Limiting the heating of food in plastic containers
• Being mindful of personal care and household product ingredients
• Reducing reliance on single-use plastics when possible

The goal is not to eliminate all exposures, which is unrealistic, but to reduce overall exposure where feasible.

The Collab Way: turning environmental research into patient care

At Collab Fertility, environmental health is part of a broader, evidence-based approach to care.

Through The Collab Way, we:

• Educate patients on environmental exposures and reproductive health
• Provide personalized, realistic recommendations
• Focus on sustainable, practical changes

We recognize that fertility is influenced by many factors, and environmental health is a meaningful and actionable part of that picture.

The Plastic Detox helps bring visibility to an important and evolving area of research.

While many questions remain, one takeaway is clear: fertility is not only biological, but also environmental, and small daily changes can greatly improve fertility outcomes for patients. 

Understanding this connection allows for more informed decisions, more comprehensive care, and a more complete view of reproductive health.

If you’re thinking about your fertility, or simply want to better understand how environmental factors may be impacting your health, our team is here to guide you with clear, personalized next steps. Book an appointment today.
