Why Your Hormones Are Low: The Mitochondrial Connection to Fertility [EP 71]
If you've been trying to conceive for months or years, feel exhausted, and have been told your hormones are low, you may have been focusing on the wrong piece of the puzzle. Many women come to me with low testosterone, low metabolized cortisol, low energy, poor recovery, and low libido. They've tried supplements, changed their diet, and sometimes even pursued hormone replacement therapy, yet they still don't feel like themselves.
In this episode of The Fertility Dietitian Podcast, we're exploring a missing piece of the hormone conversation that almost nobody is talking about: mitochondrial health. Your mitochondria don't just produce energy—they play a critical role in hormone production, egg quality, and fertility outcomes. When mitochondrial function declines, hormone production often struggles too. Understanding this connection can help you take a more effective root-cause approach to improving fertility.

Most people know mitochondria as the powerhouses of the cell.
Yes, they're responsible for producing energy. But what many women don't realize is that mitochondria do much more than that.
They're directly involved in hormone production.
In fact, the very first step of steroid hormone production happens inside the mitochondria.
This means your body relies on healthy mitochondria to produce hormones like progesterone, estrogen, testosterone, cortisol, and DHEA.
When mitochondrial function declines, hormone production can become less efficient.
Your body may have the ingredients needed to make hormones, but it may not have the cellular energy required to do that job well.
That's why looking at hormone levels alone can miss a much bigger piece of the picture.
A Hormone Pattern That May Point to Mitochondrial Dysfunction
One lab pattern I pay close attention to in practice is normal DHEA paired with low testosterone and low metabolized cortisol.
To be clear, there are multiple reasons this pattern can occur. Hormones are complex.
However, this pattern can sometimes point toward mitochondrial dysfunction.
Think of DHEA as one of the building blocks for hormone production.
If DHEA is available but downstream hormones remain low, we have to ask whether the body is having difficulty converting and utilizing those building blocks efficiently.
In some cases, mitochondrial dysfunction may be part of the answer.
This is why a root-cause approach is so important.
Simply replacing hormones doesn't necessarily address why production is struggling in the first place.
What Causes Mitochondrial Dysfunction?
Mitochondria are incredibly sensitive to their environment.
They're constantly responding to signals from your diet, lifestyle, stress levels, gut health, and toxic exposures.
Some of the most common stressors that impact mitochondrial function include chronic stress.
Whether it's emotional stress, work stress, fertility stress, financial stress, or relationship stress, your body doesn't separate these categories.
It's all stress.
Chronic stress increases oxidative stress and can impair mitochondrial performance over time.
Poor Sleep and Fertility
Sleep is one of the most powerful mitochondrial repair tools we have.
When you're consistently sleeping fewer than seven hours per night, or your sleep quality is poor, mitochondrial recovery suffers.
Over time, this can affect energy production, hormone balance, and fertility.
Blood Sugar Instability
Large blood sugar swings create oxidative stress and increase inflammation.
This places additional stress on the mitochondria and can make hormone production less efficient.
Supporting blood sugar balance is one of the most important foundational steps for improving mitochondrial health.
Gut Health and Mitochondrial Function
Gut health plays a major role in hormone production and cellular energy.
An unhealthy gut microbiome can increase inflammation, impair nutrient absorption, and contribute to toxin recirculation.
All of these factors place additional stress on the mitochondria.
This is also why digestion, absorption, and nutrient status matter so much.
If your body isn't absorbing nutrients properly, your cells may not have the resources needed to create energy efficiently.
Mineral Status Matters
Minerals are essential for cellular energy production.
They help provide the resources your mitochondria need to function optimally.
This is one reason I often use Hair Tissue Mineral Analysis (HTMA) in practice.
It can provide valuable insight into mineral balance and help identify areas where mitochondrial support may be needed.
Environmental Toxins and Hormone Production
Environmental toxins are another major contributor to mitochondrial dysfunction.
Plastics, pesticides, heavy metals, synthetic fragrances, and other chemical exposures can interfere with both mitochondrial function and hormone production.
Reducing overall toxic burden can make a meaningful difference in cellular health and fertility outcomes.
Nutrient Deficiencies and Low Hormones
Mitochondria require nutrients to function properly.
Deficiencies in nutrients such as magnesium, B vitamins, iron, selenium, zinc, CoQ10, and omega-3 fats can all impact energy production.
Even when you're consuming these nutrients, chronic stress, inflammation, gut dysfunction, and toxic burden can increase demand and divert resources away from hormone production.
This is why we need to look at the whole picture rather than focusing on a single nutrient or lab value.
Why Mitochondria Matter for Egg Quality
If you've listened to this podcast for a while, you've probably heard me talk about egg quality.
Mitochondria are one of the most important factors influencing egg quality.
In fact, the egg contains more mitochondria than any other cell in the body.
That tells us just how energy-intensive reproduction truly is.
Mitochondria provide the energy required for:
Egg maturation
Ovulation
Fertilization
Embryo development
Implantation support
Hormone production
When mitochondrial health improves, we often see improvements in fertility outcomes over time.
Egg Quality Is Responsive
One of the biggest misconceptions in fertility is that egg quality cannot be improved.
That simply isn't true.
Research, clinical experience, and client outcomes consistently show that egg quality is responsive to the environment it's exposed to during development.
The most influential window is approximately 90 days before ovulation.
However, continued improvements can occur over six to twelve months as new follicles continue to develop.
The more consistently you support mitochondrial health, reduce toxic burden, improve gut health, and optimize nutrient status, the greater the opportunity for improved egg quality.
Hormone Replacement Isn't Always the Full Answer
Hormone replacement can absolutely have a place.
In some situations, it can be extremely beneficial.
In others, it may not be the most appropriate solution.
If we only replace hormones without asking why production declined in the first place, we may miss an important opportunity to improve the underlying environment.
It's like pouring water into a bucket with a leak.
The water may temporarily help, but we still need to repair the leak.
That's the goal of root-cause fertility care.
We ask why hormone production is struggling and what stressors may be impacting the system.
How to Support Mitochondrial Health Naturally
If I were supporting mitochondrial health for fertility, these are the foundational areas I would focus on first.
Prioritize Protein
Protein provides the amino acids needed for hormone production, detoxification, tissue repair, and metabolic health.
Aim to include high-quality protein at every meal.
This also helps stabilize blood sugar.
Balance Blood Sugar
Build meals around protein, healthy fats, and fiber-rich carbohydrates.
Stable blood sugar means less oxidative stress and better support for mitochondrial function.
Eat More Antioxidant-Rich Foods
Antioxidants help protect mitochondria from oxidative damage.
Focus on colorful fruits and vegetables, herbs, spices, seafood, pasture-raised meats, and other nutrient-dense whole foods.
Prioritize Sleep
Aim for eight to nine hours of sleep whenever possible.
Morning sunlight exposure and limiting bright light after sunset can help improve sleep quality.
Support Gut Health
Focus on fiber-rich foods, fermented foods when tolerated, adequate stomach acid production, and addressing chronic digestive symptoms.
Simple habits like slowing down during meals and chewing thoroughly can also support digestion.
Reduce Toxic Burden
Choose glass over plastic when possible.
Filter your drinking water.
Reduce exposure to synthetic fragrances and unnecessary chemicals.
Small changes can add up over time.
Consider Targeted Nutritional Support
Depending on your individual needs, nutrients such as CoQ10, carnitine, magnesium, omega-3 fats, selenium, zinc, and B vitamins may provide additional support.
Always work with a qualified healthcare provider to determine what is appropriate for your situation.
The Bottom Line
One of the biggest takeaways from today's episode is this:
Low hormones are often a symptom.
They are not the root cause.
Your hormones are responding to the environment they're being produced in.
When your cells are healthy, your mitochondria are functioning well, your nutrient status is optimized, your gut is thriving, and your body feels safe, hormone production becomes much more efficient.
That's why we look beyond hormone levels alone.
We ask why the body is struggling to make hormones in the first place.
Because when we address the root cause, we often see improvements in energy, metabolism, hormone balance, fertility, and overall health.
Your hormones don't function in isolation.
They're a reflection of how well your cells are functioning.
And when you support your cells, you support your fertility.
