The Case of PCOS: Evaluating Ovarian and Adrenal Hormones

Main Hormonal Biomarkers in PCOS

Pinpointing hormonal biomarkers in PCOS plays a key role in accurate diagnosis and personalized treatment. These indicators give healthcare providers clear data to evaluate hormonal imbalances. Each biomarker - whether related to ovarian reserve, gonadotropin balance, or androgen levels - offers unique insights into the hormonal complexities of PCOS.

Anti-Müllerian Hormone (AMH)

AMH is one of the most dependable markers of ovarian function and is notably elevated in PCOS. Women with PCOS often have AMH levels about three times higher than those without the condition. This increase reflects the higher number of small follicles typically seen in PCOS.

Produced by granulosa cells, AMH serves as a reliable measure of ovarian reserve. In PCOS, the abundance of small follicles leads to an overproduction of AMH, which is why blood tests often reveal elevated levels. This makes AMH particularly useful for distinguishing PCOS from other conditions with similar symptoms.

Beyond diagnosis, AMH levels help assess the severity of ovarian dysfunction and track treatment progress over time. Unlike many hormones that fluctuate during the menstrual cycle, AMH remains relatively stable. This consistency makes it an excellent biomarker for both initial diagnosis and ongoing management.

Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH)

The balance between LH and FSH is a critical factor in understanding reproductive hormone dynamics in PCOS. An elevated LH/FSH ratio is a common finding in PCOS, caused by increased LH pulse frequency, which stimulates androgen production in the ovaries. However, it’s important to note that not all women with PCOS show this pattern.

In a typical cycle, LH triggers ovulation. But in PCOS, persistently high LH levels lead to excessive androgen production instead of supporting normal ovulation. This creates a feedback loop where high LH levels drive the ovaries to produce more testosterone and other androgens, disrupting the menstrual cycle and preventing regular ovulation.

FSH, which helps stimulate follicle development, often remains within normal ranges in PCOS. However, the altered LH/FSH ratio highlights the hormonal imbalance at play. Since this ratio varies among individuals, comprehensive hormonal testing is essential rather than relying on a single measurement.

Factors like stress, weight fluctuations, and medications can influence LH and FSH levels, further emphasizing the need for a thorough hormonal evaluation rather than isolated tests.

Androgens: Testosterone, DHEAS, Androstenedione

Elevated androgen levels are found in roughly 80% of women with PCOS, making them a cornerstone of both diagnosis and treatment planning.

• Testosterone: This is the primary androgen measured in PCOS. High testosterone levels are linked to common PCOS symptoms like hirsutism (excess facial and body hair), acne, and male-pattern hair loss. The Free Androgen Index (calculated as total testosterone divided by SHBG) is also elevated in PCOS.
• DHEAS (Dehydroepiandrosterone sulfate): This marker provides insight into adrenal androgen production. Elevated DHEAS levels suggest that the excess androgens may be coming from the adrenal glands instead of solely from the ovaries. Identifying the source of androgen excess is crucial for determining the most effective treatment approach.
• Androstenedione: A precursor to testosterone, androstenedione is often elevated in women with hyperandrogenic PCOS. Measuring this biomarker helps clarify androgen metabolism in PCOS.

Accurately measuring androgen levels can be challenging, as some common assays lack sensitivity or specificity. To ensure reliable results, androgens should ideally be measured using liquid chromatography-mass spectrometry (LC-MS) or high-quality assays. Inaccurate measurements could lead to misdiagnosis or inappropriate treatment.

Additionally, SHBG (sex hormone-binding globulin), a glycoprotein that binds to and reduces the activity of androgens, is consistently lower in women with PCOS. Lower SHBG means more biologically active "free" androgens, which amplifies the impact of elevated androgen levels. This explains why even moderate increases in total testosterone can result in pronounced symptoms of hyperandrogenism.

Together, these biomarkers form a comprehensive picture of PCOS, enabling targeted and effective treatment strategies.

How Biomarkers Help Diagnose PCOS

Hormonal biomarkers are a key tool in diagnosing PCOS, offering clarity and precision when differentiating it from other conditions. By combining these biomarkers with clinical observations, healthcare providers can make more accurate diagnoses and refine treatment plans. This section delves into the criteria and modern practices that rely on these biomarkers.

Biomarkers and Diagnostic Criteria

The Rotterdam criteria remain the most widely accepted framework for diagnosing PCOS. For a diagnosis, a patient must meet at least two of the following three conditions: hyperandrogenism (either clinical signs or biochemical evidence), oligo-anovulation, and polycystic ovarian morphology as seen on an ultrasound. Hormonal biomarkers are instrumental in confirming these conditions.

Biochemical hyperandrogenism, a hallmark of PCOS, is identified by elevated androgen levels. Research shows that approximately 80% of women with PCOS exhibit high circulating androgens. Another valuable biomarker is anti-Müllerian hormone (AMH). A threshold of 5.8 ng/mL for AMH has been shown to have 86% specificity and 70% sensitivity in diagnosing PCOS. This makes AMH a practical alternative to ultrasounds, especially for identifying polycystic ovarian morphology in adults.

The LH to FSH ratio is another useful marker. Women with PCOS often show an elevated ratio, typically around 2:1 or even 3:1, reflecting the hormonal imbalance that characterizes the condition. Biomarker testing also helps rule out other conditions with overlapping symptoms, such as thyroid disorders, hyperprolactinemia, and congenital adrenal hyperplasia.

Reading Biomarker Results

Interpreting biomarker results requires careful consideration of factors like age, ethnicity, body weight, and individual metabolic differences. These elements can influence hormone levels and impact diagnostic accuracy.

AMH has proven more effective than the antral follicle count (AFC) in distinguishing women with menstrual irregularities from those with regular cycles. However, combining both markers yields even better diagnostic accuracy. When it comes to androgen testing, the reliability of results depends on the method used. Techniques like liquid chromatography-mass spectrometry (LC-MS) or high-quality assays are preferred over standard immunoassays for consistent and accurate measurements.

For clinical hyperandrogenism, tools like the modified Ferriman-Gallwey score provide a standardized way to evaluate hair growth patterns in androgen-sensitive areas. While AMH levels remain stable throughout the menstrual cycle, hormones like LH and FSH can vary significantly, often requiring repeat tests for confirmation.

Biomarkers in Telehealth and Personalized Medicine

Telehealth is transforming how PCOS is diagnosed and managed, with biomarkers playing a central role in these advancements. By leveraging biomarker data, telehealth platforms can offer more accessible and precise diagnostic services. AI and machine learning are particularly effective in this area, with studies reporting diagnostic accuracy rates exceeding 98%.

"The effectiveness of AI and machine learning in detecting PCOS was even more impressive than we had thought." – Janet Hall, M.D., senior investigator and endocrinologist at the National Institute of Environmental Health Sciences (NIEHS)

Companies like Oana Health are taking this a step further by using biomarker data to craft personalized treatment plans. Their platform tailors therapies based on individual biomarker profiles, aligning with the principles of precision medicine.

This integration of biomarker testing with telehealth addresses a critical gap in healthcare. An estimated 70% of PCOS cases go undiagnosed, often due to limited access to specialists. Telehealth platforms make it easier to identify these cases early, improving outcomes for women who might otherwise remain undiagnosed. With AI and machine learning enhancing both detection and diagnostic accuracy, the future of PCOS care is heading toward more personalized and effective solutions.

These advancements not only improve diagnosis but also open the door to tailored treatments, marking a significant step forward in managing PCOS. By embracing biomarker-guided approaches, healthcare providers can better meet the needs of individuals living with this condition.

This approach moves away from generic treatments, offering more precise interventions that improve outcomes for women managing PCOS. Below, we explore how specific hormonal imbalances influence treatment choices.

Hormonal Treatments Based on Biomarker Profiles

Biomarker patterns play a key role in determining treatment plans. For instance:

• Elevated Androgen Levels: Anti-androgens like spironolactone are commonly prescribed. These medications block androgen receptors, helping to reduce symptoms such as acne, hair loss, and unwanted hair growth.
• Insulin Resistance and Elevated Glucose: Insulin sensitizers like metformin are often recommended. This treatment is vital for many women with PCOS, as it helps regulate glucose levels and improve insulin sensitivity.
• High AMH Levels: Elevated Anti-Müllerian Hormone (AMH) levels often indicate more severe metabolic and hormonal challenges. Research shows that women with high AMH may require more aggressive or specialized interventions.
• Elevated LH to FSH Ratios: Hormonal contraceptives are effective in regulating cycles for women with imbalanced LH and FSH levels. These medications suppress LH production and stabilize hormone levels, with specific formulations chosen based on individual symptoms.
• Inflammatory Markers: Many women with PCOS exhibit elevated pro-inflammatory cytokines like TNF-α and IL-6, while having lower levels of anti-inflammatory cytokines like IL-10. Treatments targeting inflammation alongside hormonal imbalances can be particularly beneficial for these patients.

These targeted strategies highlight how biomarker-driven care can address the complex needs of women with PCOS. Platforms like Oana Health are leading the way in integrating these insights into patient care.

"There is an urgent need for biomarkers that address both the reproductive and non-reproductive aspects of this complex syndrome."

Building on established markers, researchers are investigating new indicators that could offer a more complete understanding of PCOS.

New Biomarkers for PCOS

Emerging research is uncovering potential biomarkers that target areas traditional markers may overlook:

• 11-Oxygenated Androgens (11OHA4 and 11OHT): These provide more precise insights into hirsutism compared to standard androgen measurements.
• MicroRNAs: As non-coding RNAs that regulate gene expression, these could offer a broader view of hormonal imbalances in PCOS.
• Anogenital Distance (AGD): This marker reflects prenatal androgen exposure and might help identify PCOS risk early, potentially allowing for preventive measures before symptoms appear.
• Urinary ACE2: This marker could predict kidney complications in PCOS, independent of factors like diet, helping identify women who may require closer health monitoring.

Role of Multi-Omics and Artificial Intelligence

Beyond individual biomarkers, the integration of multi-omics data with artificial intelligence (AI) is reshaping our understanding of PCOS. Multi-omics approaches allow researchers to analyze vast biological datasets, offering deeper insights into the condition.

AI is proving especially transformative. In 2023, Su Z introduced a support vector machine (SVM) model using genetic data that achieved an impressive area under the curve (AUC) of 100% for predicting PCOS. AI is also helping to identify distinct PCOS subtypes. For example, in 2024, Van der Ham K and colleagues demonstrated that metabolic, reproductive, and background subtypes of PCOS could be distinguished using additional clinical variables. This suggests that PCOS may actually consist of several different conditions, each requiring a tailored treatment approach.

"Given the large burden of under- and mis-diagnosed PCOS in the community and its potentially serious outcomes, we wanted to identify the utility of AI/ML in the identification of patients that may be at risk for PCOS", stated Janet Hall, M.D., senior investigator and endocrinologist at the National Institute of Environmental Health Sciences (NIEHS).

Some AI models using metabolomic data have achieved perfect sensitivity and specificity in predicting treatment responses. Beyond diagnosis, these technologies can forecast how patients will respond to specific medications, enabling doctors to choose the most effective treatments from the start. AI can also track treatment compliance and suggest personalized dosing schedules, refining care to match individual needs.

"Across a range of diagnostic and classification modalities, there was an extremely high performance of AI/ML in detecting PCOS, which is the most important takeaway of our study", noted Skand Shekhar, M.D., senior author and assistant research physician at NIEHS.

These advancements are paving the way for personalized PCOS management, especially in telehealth settings.

Impact on Telehealth Delivery

Breakthroughs in biomarker research are set to revolutionize how PCOS care is delivered via telehealth. Telehealth platforms, with their ability to quickly adopt new diagnostic tools, stand to benefit significantly. For instance, platforms like Oana Health could use advanced biomarkers to guide treatment decisions during initial consultations. This could eliminate much of the trial-and-error typically involved in finding effective therapies, reducing delays and minimizing side effects from unsuitable medications.

AI integration could further enhance telehealth services. Predictive algorithms might analyze biomarker trends to detect when treatments need adjustment, preventing symptom escalation and improving long-term outcomes.

However, challenges remain. Data bias in AI systems could lead to unequal treatment effectiveness across different populations. Additionally, advanced biomarker testing may initially be costly, requiring telehealth providers to balance precision medicine with affordability.

Despite these hurdles, the potential benefits are immense. Combining advanced biomarkers, AI-driven analysis, and telehealth could make high-quality PCOS care accessible to patients no matter where they live.

"The field of biomarkers in PCOS is rapidly evolving, continuously bringing new developments for this complex and challenging disease."

The ability to monitor biomarker patterns in real-time could also transform follow-up care.
