The Hidden Link Between Autoimmunity and Infertility [EP 73]
If you've been trying to conceive for months or even years and no one has talked to you about your immune system, this episode is for you.
One of the biggest misconceptions in fertility is that autoimmune diseases only matter once they've been diagnosed. But the reality is that immune dysfunction often begins years before symptoms ever appear. During that time, chronic low-grade inflammation can quietly influence hormone production, egg quality, implantation, and your ability to maintain a healthy pregnancy. In this episode, I'm breaking down why your immune system matters for fertility, why autoimmune conditions have become so much more common, and—most importantly—what you can do to create a healthier environment for conception.
The good news? Having an autoimmune condition does not mean you can't have a healthy pregnancy. Your genes are not your destiny. Every meal, every night of restorative sleep, every walk outside, every effort to improve gut health, stabilize blood sugar, and lower inflammation sends your immune system new information. Small changes, repeated consistently over time, can completely change the environment where fertility begins.

Transcript:
This is a highly requested topic, and I'm excited to finally dive into it.
If you've been trying to conceive for months or even years and no one has talked to you about your immune system, this episode is for you. Even if you already have an autoimmune condition, you'll likely learn something new about how immune health influences fertility.
One of the biggest misconceptions in fertility is that autoimmune diseases only matter after they've been diagnosed. In reality, autoimmunity often begins years—sometimes even a decade—before symptoms appear.
During that time, the immune system can quietly create inflammation that affects hormone production, egg quality, implantation, and maintaining a healthy pregnancy.
Today, we're talking about why your immune system matters for fertility, how autoimmune conditions develop, why they're becoming more common, and what you can do to help regulate immune function and create a healthier environment for pregnancy.
I also want to start with something incredibly important.
Having an autoimmune condition does not mean you can't have a healthy pregnancy.
I've worked with many couples where immune dysfunction was one of the missing pieces. When we stopped chasing symptoms and started improving the environment the immune system was functioning in, inflammation decreased, lab work improved, and pregnancies followed.
Your genes are not your destiny. They're simply instructions waiting for signals from your environment.
What Is Autoimmunity?
Autoimmune diseases are now the third most common category of chronic illness behind cardiovascular disease and cancer.
Women account for nearly 80% of autoimmune diagnoses and are about four times more likely than men to develop an autoimmune condition.
There are now more than 100 recognized autoimmune diseases, including:
Hashimoto's thyroiditis
Graves' disease
Rheumatoid arthritis
Lupus
Psoriasis
Multiple sclerosis
Celiac disease
Inflammatory bowel disease
Although these diseases affect different tissues, they all share one thing in common.
The immune system loses tolerance and begins reacting against healthy tissues instead of protecting them.
Functional medicine asks an important question that conventional medicine often doesn't:
Why did the immune system lose tolerance in the first place?
Autoimmune diseases don't appear overnight. They develop over years through a combination of genetic susceptibility and environmental exposures that influence how our genes are expressed.
Your DNA may load the gun, but your environment pulls the trigger.
How Autoimmunity Affects Fertility
Many people think of the immune system as something that only fights infections.
In reality, reproduction is one of the most immune-dependent processes in the body.
A developing embryo contains half of your partner's genetic material. From an immune perspective, it isn't completely "self."
Your immune system has to perform an incredible balancing act.
It must remain strong enough to protect both mother and baby from infection while also becoming tolerant enough to support implantation and pregnancy.
Before implantation, the uterine lining becomes populated with specialized immune cells that help prepare the endometrium, remodel blood vessels, support placental development, regulate inflammation, and communicate with the embryo.
Implantation itself is actually a carefully controlled inflammatory event.
For a brief period, inflammation helps the embryo attach. Immediately afterward, the immune system should shift into a more tolerant, anti-inflammatory state to support pregnancy.
When immune regulation is disrupted, that transition may not occur efficiently.
Research has associated immune dysfunction with:
Longer time to conception
Implantation failure
Recurrent miscarriage
Placental dysfunction
Pregnancy complications
Reduced IVF success rates
This doesn't mean autoimmunity is always the cause.
But if you've experienced unexplained infertility, recurrent pregnancy loss, repeated implantation failure, thyroid antibodies, or multiple autoimmune conditions within your family, your immune system deserves a much closer look.
Hashimoto's and Fertility
Hashimoto's thyroiditis is the autoimmune condition I see most often in fertility practice.
Many women are told their thyroid is "normal" because thyroid hormone levels fall within the reference range.
The problem is that thyroid antibodies often aren't measured.
You can have normal thyroid hormone production while antibodies are actively attacking thyroid tissue.
Research shows elevated thyroid antibodies are associated with increased miscarriage risk and fertility challenges—even when thyroid hormone levels appear normal.
This is why I recommend including thyroid antibodies as part of every comprehensive fertility workup.
We're not simply asking whether the thyroid is functioning today.
We're asking whether the immune system is creating unnecessary inflammation that could interfere with fertility.
Why Autoimmune Diseases Are Increasing
Our genes haven't changed dramatically over the past few generations.
Our environment has.
Several factors are contributing to increased immune dysfunction, including:
Environmental toxins
Heavy metals
Plastics and endocrine disruptors
Air pollution
Mold exposure
Chronic infections
Poor gut health
Circadian rhythm disruption
Chronic stress
Nutrient deficiencies
Blood sugar instability
Physical inactivity
These factors increase inflammation, oxidative stress, and immune dysregulation while placing additional demands on the body.
How to Calm the Immune System Naturally
The goal is not to suppress your immune system.
The goal is to help it become more regulated.
The first step is identifying what's keeping the immune system activated.
That may include infections, food sensitivities, mold exposure, poor sleep, insulin resistance, oxidative stress, or other hidden barriers.
At the same time, I like monitoring inflammatory markers over time, including CRP, ESR, ferritin, and additional immune markers when appropriate.
Focus on Nutrition
Your immune cells require an incredible amount of energy and nutrients to function properly.
Build meals around:
High-quality protein
Colorful fruits and vegetables
Healthy fats
Fiber-rich whole foods
Herbs and spices
Adequate minerals
This isn't about restriction.
It's about supplying the building blocks your immune system needs to regulate itself.
Heal the Gut
Nearly 70% of immune cells are associated with the gastrointestinal tract.
When the gut barrier becomes damaged or the microbiome loses diversity, immune activation increases.
Addressing infections, improving microbial diversity, repairing the gut lining, and feeding beneficial bacteria with fiber-rich foods can significantly improve immune function.
A healthier gut often leads to a healthier immune response.
Reduce Toxic Exposure
You can't eliminate every toxin.
Perfection isn't the goal.
Instead, focus on lowering your overall toxic burden by:
Improving indoor air quality
Drinking filtered water
Choosing lower-tox personal care products
Staying hydrated with electrolytes
Prioritizing fiber
Sweating regularly through exercise or sauna when appropriate
Eating antioxidant-rich foods daily
Support Your Stress Response
It's impossible to eliminate stress completely.
Instead, help your body adapt more effectively.
Support your circadian rhythm by getting outside within the first hour of waking.
Limit artificial light at night.
Strength train.
Walk regularly.
Stabilize blood sugar.
Prioritize sleep.
Create routines that tell your nervous system it's safe.
Remember, your nervous system and immune system are constantly communicating.
Support Your Mitochondria
Your mitochondria produce the energy every immune cell requires.
When inflammation and toxins damage mitochondria, immune regulation becomes much more difficult.
Support mitochondrial health with:
Adequate protein
Regular movement
Magnesium
Omega-3 fatty acids
CoQ10
L-carnitine
Antioxidant-rich foods
Restorative sleep
Food should always be the foundation.
Supplements should be individualized based on your specific needs.
Healthy mitochondria support healthy immune cells, healthy eggs, healthy sperm, and healthy fertility.
Testing I Commonly Consider
When autoimmunity is on my radar, testing may include:
ANA with reflex testing
Comprehensive thyroid panel with thyroid antibodies
High-sensitivity CRP
ESR
Hemoglobin A1C
Fasting insulin
Ferritin and complete iron panel
Advanced lipid markers when appropriate
Comprehensive stool testing
Hair Tissue Mineral Analysis (HTMA)
Mycotoxin testing when indicated
Heavy metal testing when indicated
Post-Viral Immune Activation
This is an area receiving much more attention.
Sometimes an infection resolves, but the immune system never fully returns to baseline.
Instead, it remains in a heightened state of activation.
When clinically appropriate, additional testing may include:
Cytokine panels
Epstein-Barr virus antibodies
HHV-6 antibodies
The goal isn't simply identifying past infections.
It's understanding whether your immune system is still responding to them.
Final Thoughts
If there's one thing I hope you take away from today's episode, it's this:
Autoimmunity isn't simply a diagnosis.
It's a reflection that the immune system has lost balance—and that balance can often be improved.
Every meal, every night of quality sleep, every walk outside, every effort to improve gut health, stabilize blood sugar, reduce inflammation, support your mitochondria, and lower your toxic burden is sending your immune system new information.
This isn't about perfection.
It's about consistently making choices that create a healthier environment for fertility.
Small changes, repeated over time, can have a profound impact.
Your body is always listening.
The question is: What messages are you sending it?
