PCOS, Women's Repro Health, Mitochondria & Oxidative Stress
What Is Oxidative Stress?
Oxidative stress happens when there's an imbalance between free radicals and antioxidants in the body. Free radicals are unstable molecules that can harm cells, while antioxidants act as the body’s natural defense system. When free radicals outnumber antioxidants, oxidative stress occurs.
"Oxidative stress is a phenomenon caused by an imbalance between production and accumulation of oxygen reactive species (ROS) in cells and tissues and the ability of a biological system to detoxify these reactive products."
When the body can't neutralize free radicals effectively, these molecules can damage cells, proteins, and even DNA. This damage can lead to chronic inflammation and interfere with essential processes, like hormone production.
How Reactive Oxygen Species (ROS) Work in Your Body
Reactive oxygen species (ROS) are key players in oxidative stress. These molecules include superoxide anion, hydrogen peroxide, and hydroxyl radicals. While ROS are often associated with harm, they serve important purposes at low levels. For example, they help regulate blood pressure, support brain function, and strengthen the immune system’s ability to fight infections. ROS are also vital for reproductive health.
Your body naturally produces ROS during routine activities. The mitochondria, often called the powerhouses of cells, generate ROS as byproducts of energy production. Interestingly, less than 5% of oxygen molecules processed in mitochondria convert into ROS. Even this small percentage can become problematic if antioxidant defenses are overwhelmed.
Normally, enzymes like catalase and glutathione peroxidase work to neutralize ROS. But when ROS levels rise too high, these defenses may not be enough to prevent damage.
When Oxidative Stress Causes Problems
Oxidative stress becomes harmful when free radical production outweighs the body’s ability to manage it. This imbalance can result from internal processes and external factors. Internally, oxidative stress can be triggered by immune system activity, inflammation, infections, mental stress, overexertion, and the natural aging process. As you age, your antioxidant defenses may weaken, increasing the risk of cellular damage from ROS.
External factors also play a big role. Environmental pollutants, heavy metals, certain medications, chemical solvents, and radiation can all raise ROS levels. Lifestyle choices further contribute - cigarette smoke is particularly damaging, with each puff releasing approximately 10^15 free radicals. Alcohol consumption, poor diet, and exposure to byproducts from smoked meats or reused cooking oils can also worsen oxidative stress.
When oxidative stress takes over, the resulting cellular damage can disrupt hormonal systems that control metabolism, stress response, and reproductive health. The hydroxyl radical, one of the most damaging ROS, has an extremely short lifespan (less than 1 nanosecond), making it nearly impossible to neutralize once formed. For women, this imbalance can significantly affect hormonal health, potentially disrupting menstrual cycles, fertility, and metabolic processes. These effects not only harm cells but also set the stage for broader hormonal issues, which will be explored further below.
How Oxidative Stress Disrupts Your Hormones
Your hormonal system is particularly vulnerable to oxidative stress. When free radicals overpower your body's antioxidant defenses, they interfere with hormone production and balance. Here's how oxidative stress specifically impacts adrenal, thyroid, and reproductive hormones.
Adrenal Hormones and the Stress Response
Your adrenal glands produce cortisol to help manage stress. However, chronic stress leads to excessive cortisol production, which activates stress hormone receptors and increases the generation of reactive oxygen species (ROS) in your cells. This process not only raises oxidative stress but also strains mitochondrial function. Interestingly, up to 40% of the electron flow involved in cortisol synthesis can produce ROS, putting additional pressure on adrenal enzyme systems. This oxidative burden can damage essential enzymes needed for adrenal steroid production, disrupting cortisol and aldosterone levels.
Animal studies have shown that ACTH stimulation can deactivate sulfinic PRDX3, which allows hydrogen peroxide (H₂O₂) to build up. This buildup suppresses STAR protein synthesis and steroidogenesis. Similarly, research on human cells has revealed that excessive glucocorticoids can lead to ROS overproduction, disturbing metabolic processes and impairing vascular endothelial function. These disruptions in adrenal function can worsen stress-related symptoms and throw your hormonal balance further off track.
Thyroid Hormones and Metabolism
The thyroid gland naturally generates ROS during iodide oxidation, a key step in hormone production. When antioxidant defenses fall short, excess ROS can damage enzymes like thyroid peroxidase (TPO), disrupting the production of thyroid hormones. In cases of hypothyroidism, inadequate antioxidant support allows free radicals to accumulate, as seen in elevated malondialdehyde (MDA) levels - even in mild or subclinical conditions. On the flip side, hyperthyroidism ramps up mitochondrial respiration, leading to excessive ROS production and increased lipid peroxidation.
This oxidative imbalance is particularly concerning in autoimmune thyroid disorders. For example, studies have found a link between lower glutathione levels and higher anti-TPO antibody levels in individuals with Hashimoto's thyroiditis. Additionally, patients with papillary thyroid cancer often show a more severe oxidative stress profile. These disruptions can have a profound effect on metabolism and energy regulation.
Sex Hormones and Reproductive Health
Oxidative stress can also interfere with reproductive hormones, including estrogen, progesterone, and testosterone, potentially leading to fertility challenges. While estrogen generally helps reduce oxidative stress, progesterone may increase it. An imbalance between these hormones can lower levels of sex hormone–binding globulin, which can contribute to hyperandrogenemia - a hallmark of polycystic ovary syndrome (PCOS).
Oxidative stress also impacts ovarian cell function, which can lead to reduced progesterone levels and irregular menstrual cycles. Over time, as the body’s antioxidant capacity diminishes with age and ROS levels rise, reproductive function may decline further. In assisted reproductive treatments, higher ROS levels and lower antioxidant activity in oocytes, cumulus oophorus, and follicular fluid have been associated with poorer outcomes. For men, oxidative damage can impair sperm motility. More broadly, oxidative stress can disrupt the hypothalamic-pituitary-gonadal axis, affecting overall reproductive health and fertility. These hormonal imbalances underscore the critical role of oxidative stress in reproductive wellness.
Oxidative Stress and PCOS: What You Need to Know
For women with polycystic ovary syndrome (PCOS), oxidative stress plays a significant role in the condition's progression. It’s not just a side effect - it’s deeply intertwined with the underlying mechanisms of PCOS. This creates a feedback loop where oxidative stress worsens PCOS symptoms, and those symptoms, in turn, fuel more oxidative stress.
PCOS impacts 6–10% of women. Research has consistently shown that women with PCOS have noticeably different oxidative stress profiles compared to those without the condition. For instance, studies reveal that circulating mean malondialdehyde (MDA) levels - an indicator of lipid damage caused by free radicals - are 47% higher in women with PCOS compared to healthy controls. Let’s explore how healthcare providers test for these markers to develop tailored treatment plans.
Testing for Oxidative Stress in PCOS
Doctors use specific blood tests to measure oxidative stress and antioxidant levels in women with PCOS. These tests focus on markers like malondialdehyde (MDA) and nitric oxide (NO), which indicate oxidative damage. MDA, for example, reflects the extent of lipid damage caused by free radicals. Other markers, such as advanced glycosylated end products (AGEs) and xanthine oxidase (XO), also help assess oxidative stress levels.
On the flip side, antioxidant markers are tested to gauge the body’s defense against oxidative stress. These include total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione (GSH). Interestingly, studies have shown that SOD activity is 34% higher in women with PCOS compared to healthy individuals, possibly as a compensatory response to increased oxidative stress.
| Oxidative Stress Markers | Blood Source | PCOS vs. Healthy Women |
|---|---|---|
| Malondialdehyde (MDA) | Serum/Red blood cells | 47% higher |
| Nitric oxide (NO) | Serum | Higher or similar |
| Advanced glycosylated end products (AGEs) | Serum | Higher |
| Xanthine oxidase (XO) | Serum | Higher |
Additionally, vitamin levels are often assessed, as women with PCOS tend to have lower concentrations of vitamin E and vitamin C. These tests provide a detailed picture of oxidative stress and help guide personalized treatment strategies aimed at breaking the cycle of PCOS-related complications.
How Oxidative Stress Worsens Insulin Resistance and High Androgens
Oxidative stress doesn’t just coexist with PCOS - it actively worsens two of its hallmark challenges: insulin resistance and elevated androgen levels. Insulin resistance affects 50–80% of women with PCOS, and oxidative stress makes it even harder for the body to manage insulin effectively. Elevated androgens, in turn, increase oxidative stress, which further reduces insulin sensitivity in skeletal muscles.
This creates a self-reinforcing loop: insulin resistance leads to higher insulin levels (hyperinsulinemia), which then stimulate the ovaries to produce even more androgens. These excess androgens not only worsen oxidative stress but also contribute to other PCOS symptoms. It’s worth noting that 60–75% of women with PCOS have higher androgen levels, and 40–70% struggle with obesity, both of which amplify oxidative stress and insulin resistance.
The promising news? Reducing oxidative stress can help break this cycle. Antioxidant therapies, along with lifestyle changes like a balanced diet, regular exercise, and weight management, have been shown to improve insulin sensitivity in skeletal muscles. By addressing oxidative stress directly, women with PCOS can see improvements in both insulin resistance and androgen levels.
For women navigating PCOS, tackling oxidative stress and insulin resistance is essential.

How to Reduce Oxidative Stress and Improve Your Hormones
The encouraging news is that there are practical steps you can take to reduce oxidative stress and support better hormone balance. Research highlights that the right combination of nutrition, lifestyle changes, and medical treatments can significantly enhance your body’s ability to combat oxidative damage while promoting hormonal well-being.
Foods and Supplements That Help Combat Oxidative Stress
What you eat plays a huge role in managing oxidative stress. Antioxidants, found in food and supplements, are key players in reducing the damage caused by free radicals. The goal is to focus on nutrients that have been shown to protect your cells and support hormone production.
Some of the most effective antioxidants include vitamins A, C, and E, along with minerals like selenium and zinc. For instance, vitamin C acts as a water-soluble antioxidant essential for collagen production, while vitamin E is a lipid-soluble antioxidant that protects cell membranes.
Incorporate antioxidant-rich foods into your meals, such as colorful fruits, vegetables, spices, and even dark chocolate. While supplements like vitamins C and E can also help, it’s best to consult with a healthcare professional before adding them to your routine. Whole foods generally provide antioxidants in a more effective form compared to supplements.
"The foundation of good nutrition - fruit, veggies, nuts, seeds, beans - hasn't changed. If you're eating animal protein, [try] seafood options and stay away from processed meats." - Taylor Wolfram, RDN
Beyond improving your diet, making adjustments to your daily habits can further reduce oxidative stress.
Lifestyle Adjustments That Make a Difference
Changing certain lifestyle habits can not only lower oxidative stress but also help balance your hormones. Key strategies include regular exercise, maintaining a healthy weight, avoiding smoking and excessive alcohol, and managing stress.
Exercise is particularly effective, as it enhances your body’s antioxidant defenses and reduces inflammation. Aim for 150 minutes of moderate aerobic activity each week.
Maintaining a healthy weight is equally important, as both obesity and being underweight can contribute to oxidative stress and hormone imbalances. A body mass index (BMI) between 18.5 and 24.9 kg/m² and a waist circumference below 40 inches for men and 35 inches for women are ideal targets.
Steering clear of tobacco and limiting alcohol consumption can also significantly reduce oxidative stress and support hormonal health.
Stress management is crucial, as chronic stress can lead to excessive cortisol production, disrupting hormonal balance. Incorporate practices like mindfulness, therapy, or relaxation techniques into your routine to help keep stress in check.
A 2019 study highlighted how an intensive lifestyle intervention - combining nutrition education, exercise goals, and regular check-ins - led to measurable improvements in oxidative stress markers, such as increased superoxide dismutase (SOD) and reduced malondialdehyde (MDA), in individuals with type 2 diabetes.
While these lifestyle changes are impactful, medical treatments can provide additional support when needed.
Medical Treatments for Hormonal Issues
If lifestyle changes aren’t enough, medical treatments can offer targeted solutions. Antioxidant supplements are increasingly being used alongside conventional therapies for hormone-related conditions. These treatments complement lifestyle adjustments by directly addressing oxidative stress and hormonal imbalances.
For women with PCOS, medications like Metformin can help manage insulin resistance, a major contributor to oxidative stress. Oana Health offers Metformin starting at $22 per month, and their Metformin & Spironolactone combination pack, priced at $32 monthly, targets both insulin sensitivity and androgen-related symptoms.
Plant-based compounds, including alkaloids, flavonoids, phenolic acids, and coumarins, have shown promise in reducing oxidative stress and supporting hormone health.

When to Get Medical Help for Hormone Problems
It's important to seek medical advice when symptoms like irregular menstrual cycles, persistent hair loss, or unwanted hair growth don't improve with lifestyle changes. These issues could signal a deeper hormonal imbalance connected to oxidative stress.
PCOS, or polycystic ovary syndrome, is a common and complex cause of hormonal disruptions. It often involves insulin resistance, elevated androgen levels, and oxidative stress, all of which may require medical intervention.
Monitoring Your Oxidative Stress and Hormone Levels
If symptoms persist, the next logical step is to evaluate your oxidative stress and hormone levels. Testing can uncover how oxidative stress affects your hormones. Healthcare providers often measure biomarkers such as MDA, 8-OHdG, and antioxidant enzymes like SOD, catalase, and glutathione peroxidase. These tests help to assess the balance between oxidative damage and your body's antioxidant defenses.
For hormone evaluation, cortisol testing is particularly insightful. Chronic stress can disrupt hormonal balance, and cortisol levels provide valuable clues. Normal blood cortisol levels range from 0.05 µg/mL to 0.25 µg/mL, while urinary free cortisol levels typically fall between 36 µg/24 h and 137 µg/24 h. Salivary cortisol testing offers a convenient, non-invasive method that aligns closely with blood cortisol readings.
The DUTCH Complete™ test is another powerful tool, providing a detailed overview of sex hormones, cortisol levels, and related metabolites, along with oxidative stress markers. This comprehensive analysis helps healthcare providers design precise treatment plans tailored to your needs. Regular testing also allows your healthcare team to monitor your progress and adjust treatments as needed.

Conclusion: Better Hormones Through Managing Oxidative Stress
Tackling oxidative stress can play a key role in restoring hormonal balance and easing symptoms, especially for conditions like PCOS. Studies show that reducing oxidative stress can lead to noticeable improvements in hormonal health.
As mentioned earlier, oxidative stress doesn’t just disrupt hormones - it also contributes to conditions like PCOS. Since PCOS impacts a large number of women of reproductive age, addressing oxidative stress becomes a vital part of managing this condition.
Research highlights antioxidant therapy as a promising avenue for PCOS treatment. For instance, findings from Jamilian et al. revealed that combining vitamin D and omega-3 significantly lowered total testosterone levels and inflammatory markers while enhancing the body's antioxidant capacity. Similarly, pairing vitamin E with omega-3 showed improvements in inflammatory gene expression. These studies underscore the importance of a well-rounded approach.
The most effective strategies combine lifestyle changes with targeted treatments. Weight loss, regular exercise, and a balanced diet provide the foundation for managing hormone imbalances. When necessary, additional treatments like hormonal contraceptives with anti-androgen properties, metformin, or specific anti-androgens can offer extra support.
Even small steps with antioxidants can make a difference. Supplements such as CoQ10, magnesium and zinc blends, or natural compounds like quercetin and ellagic acid have been shown to improve hormone levels and symptoms.

FAQs
How does oxidative stress affect women with PCOS, and what steps can help manage it?
Oxidative stress (OS) plays a major role in the challenges faced by women with PCOS. It can throw hormonal balance off course, aggravate symptoms like insulin resistance, and lead to ovarian dysfunction. On top of that, OS can trigger irregular ovulation and inflammation, making PCOS even harder to manage.
Taking steps to reduce oxidative stress can make a difference. Lifestyle adjustments are a great place to start. For instance, maintaining a healthy weight can help lower the production of harmful reactive oxygen species (ROS). Adding antioxidant-rich foods - like berries, nuts, and leafy greens - or supplements to your diet can also help restore balance. These measures may improve ovulation, protect ovarian follicles from oxidative damage, and promote better reproductive health. For tailored advice, it’s a good idea to consult a healthcare provider who specializes in hormonal health, such as Oana Health.
What lifestyle changes can help lower oxidative stress and improve hormonal balance?
Reducing oxidative stress and maintaining hormonal balance can be achieved with a few straightforward lifestyle adjustments. Start with regular moderate exercise, which not only helps keep hormones in check but also reduces inflammation. Try to get at least 150 minutes of physical activity each week. Additionally, focus on managing stress through practices like mindfulness, yoga, or deep breathing exercises. Chronic stress often worsens oxidative stress and disrupts hormonal balance, so finding ways to relax is key.
Your diet is another critical factor. Include plenty of antioxidant-rich foods in your meals - think berries, leafy greens, nuts, and seeds.
