Emerging Biomarkers: AMH in Androgen Dysregulation

Androgen dysregulation, particularly in conditions like PCOS, affects millions of women worldwide, with symptoms like irregular periods, excess hair growth, and infertility. Anti-Müllerian Hormone (AMH) is gaining attention as a reliable diagnostic tool for PCOS, outperforming traditional methods like serum androgens, LH/FSH ratios, and ovarian ultrasounds in many cases. Here's what you need to know:

Key Takeaways:

• PCOS Prevalence: Affects 6%–20% of women of reproductive age; 60%–80% experience hyperandrogenism.
• AMH as a Biomarker: AMH levels are 2–4 times higher in PCOS patients, with a sensitivity of 78% and specificity of 87%.
• Diagnostic Strength: AMH shows higher accuracy (AUC = 0.888) compared to traditional markers like testosterone and LH.
• Practical Benefits: AMH testing can be done anytime during the menstrual cycle, making it convenient and cost-efficient.

Why It Matters:

AMH not only aids in diagnosing PCOS but also helps predict metabolic risks and tailor treatments. While serum androgens and ultrasounds remain useful, AMH provides a more stable and accessible option, especially when imaging or symptom variability complicates diagnosis.

For those managing PCOS, telehealth platforms like Oana Health are simplifying care by integrating AMH testing and offering targeted treatments for symptoms like excess hair growth, hair loss, and insulin resistance - all delivered conveniently to your door. This shift is transforming how hormonal health is diagnosed and treated, making care more accessible and precise.

Anti-Müllerian Hormone Levels: A New Perspective on PCOS Management

1. Anti-Müllerian Hormone (AMH)

Anti-Müllerian Hormone (AMH) has emerged as a key biomarker in diagnosing PCOS, particularly for assessing androgen dysregulation. Its stability over time makes it a flexible option for testing, while also providing valuable insights into ovarian reserve and function.

Diagnostic Accuracy

Research highlights AMH's diagnostic strength compared to other markers. For instance, in a study involving 421 women, AMH outperformed serum testosterone (AUC = 0.725) and luteinizing hormone (LH, AUC = 0.779), achieving an overall AUC of 0.888. It demonstrated a sensitivity of 83.93% and a specificity of 80.63%. These results held strong across different populations, with an AUC of 0.879 in obese women and 0.903 in non-obese women.

Another study conducted at Isra University in Karachi (June 2023–June 2024) further reinforced AMH's diagnostic relevance. Among 100 participants clinically diagnosed with PCOS, there was a significant positive correlation between AMH levels and polycystic ovarian morphology (p < 0.0001).

However, AMH is not without limitations. When used alone, its diagnostic performance for PCOS peaks at a threshold of 3.44 ng/mL, yielding a sensitivity of 77.78% and specificity of 68.89%. These findings underscore the need to evaluate AMH alongside other diagnostic markers.

Ease of Access

One of AMH's biggest advantages is its practicality. Unlike estradiol and follicle-stimulating hormone, AMH levels remain stable throughout the menstrual cycle, allowing for off-cycle blood testing. This makes it especially useful in areas with limited access to advanced imaging technologies. A simple blood test can provide critical diagnostic insights without requiring specialized equipment or highly trained personnel.

Cost Effectiveness

AMH testing is also cost-efficient. By eliminating the need for multiple cycle-timed blood draws, it streamlines the diagnostic process and optimizes resource use in clinical settings.

Clinical Applicability

Elevated AMH levels have been linked to metabolic disturbances such as insulin resistance, hyperglycemia, and dyslipidemia. Recent international guidelines on PCOS highlight AMH's importance in diagnosis. When incorporated into the Rotterdam criteria as an additional parameter, AMH improved diagnostic sensitivity to 80% and achieved 100% specificity. Replacing the subjective criterion of polycystic ovarian morphology with AMH levels further enhanced sensitivity to 86.67%, while maintaining 100% specificity.

Beyond diagnosis, AMH shows promise in risk stratification. It may help identify women with PCOS who are at higher risk for cardiometabolic complications. Early detection is critical for effective management and can shape treatment strategies to address both reproductive and metabolic concerns.

2. Serum Androgens (e.g., Testosterone, DHEAS)

Serum androgen testing plays a key role in identifying biochemical hyperandrogenism in PCOS. It involves measuring markers like total testosterone (TT), calculated free testosterone (cFT), free androgen index (FAI), androstenedione (A4), and dehydroepiandrosterone sulfate (DHEAS).

Diagnostic Accuracy

The 2023 International PCOS Guidelines recommend total testosterone and free testosterone as the primary tests for detecting biochemical hyperandrogenism. According to meta-analyses, here’s how these tests perform:

Testosterone levels exceeding 0.41 ng/ml demonstrate high diagnostic accuracy, with 85% sensitivity and 96.7% specificity. Androstenedione is elevated in 88% of PCOS cases, compared to 65% for testosterone. When markers are combined, diagnostic accuracy improves significantly, reaching 94.2%.

Ease of Access

Serum androgen tests are widely available across U.S. clinical labs. However, the accuracy of results depends heavily on the testing method. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is considered the gold standard due to its superior sensitivity and specificity, outperforming direct immunoassays. It's worth noting that androgen levels can fluctuate, so timing the test correctly is particularly important for women with irregular menstrual cycles.

Cost Effectiveness

These tests are also budget-friendly. Measuring testosterone and androstenedione is often sufficient for diagnosis, with A4 and DHEAS serving as secondary markers when needed. This approach helps streamline the diagnostic process while keeping costs manageable, making it a practical option for clinical decision-making in PCOS management.

Clinical Applicability

Beyond diagnosis, serum androgen levels provide valuable insights for ongoing care. These measurements can assist in predicting metabolic risks and tailoring treatment plans for PCOS-related concerns like unwanted facial hair, hair thinning, and acne. For telehealth providers like Oana Health, integrating these tests into hormonal assessments ensures a more personalized approach to managing PCOS symptoms and improving patient outcomes.

3. LH/FSH Ratio

The LH/FSH ratio, which compares luteinizing hormone (LH) to follicle-stimulating hormone (FSH), offers valuable insight into hormonal imbalances linked to PCOS, complementing serum androgen assessments. In women without PCOS, this ratio typically falls between 1 and 2. However, in those with PCOS, it often increases to a range of 2 to 3, reflecting disruptions in hormonal regulation.

Diagnostic Accuracy

Research on Sudanese women with PCOS revealed that an LH/FSH ratio cutoff of 0.749 achieved an impressive diagnostic performance, with an AUC of 0.932, 86.3% sensitivity, and 95% specificity. In comparison, Anti-Müllerian Hormone (AMH) demonstrated a slightly higher predictive value (AUC = 0.888) than LH alone (AUC = 0.779). Interestingly, as serum AMH levels rise, follicular phase gonadotropin levels shift to become more LH-dominant, highlighting the importance of evaluating both markers together for a more complete clinical picture.

Ease of Access

LH and FSH tests are widely accessible in clinical labs across the United States and are often included in standard hormonal panels. However, because gonadotropin levels vary throughout the menstrual cycle, timing the test appropriately is crucial for accurate results. Despite some variability, the availability of these tests makes them a practical option for many healthcare providers.

Cost Effectiveness

LH and FSH tests are relatively affordable and generally covered by insurance, making the calculation of the LH/FSH ratio an economical first step in hormonal evaluations. That said, its slightly lower sensitivity compared to AMH may require follow-up testing in certain cases to confirm findings.

Clinical Applicability

The LH/FSH ratio is not only useful in diagnosing PCOS but also in gauging symptom severity. For instance, LH levels above 7 iU/L are associated with a 13.9-fold increase in the likelihood of oligo/amenorrhea compared to levels below 1.

This ratio also has implications for fertility outcomes. Women with LH/FSH ratios between 1 and 2 tend to experience higher clinical pregnancy rates (odds ratio = 1.71) and live birth rates (odds ratio = 1.73). Conversely, ratios between 2 and 3 have been linked to lower miscarriage rates (odds ratio = 0.38).

The LH/FSH ratio remains a reliable tool for assessing hormonal imbalances, even when considering factors like BMI. Studies have shown consistent values in both normal-weight and overweight women with PCOS (2.76 vs. 2.79, P = 0.48), underscoring its stability as a diagnostic marker. While AMH may outperform the LH/FSH ratio as a standalone diagnostic tool, incorporating the ratio into assessments provides a broader perspective, aiding in both diagnosis and treatment planning for androgen-related disorders.

4. Ovarian Ultrasound for Polycystic Morphology

Ovarian ultrasound plays a key role in identifying polycystic ovary morphology (PCOM), which is often linked to androgen imbalances in polycystic ovary syndrome (PCOS). By providing a clear view of ovarian structure and follicle patterns, this imaging method helps clinicians assess the physical characteristics associated with the condition.

The Rotterdam criteria define PCOM as the presence of 12 or more follicles measuring 2–9 mm in diameter or an ovarian volume exceeding 10 cm³. However, updated PCOS guidelines from 2018 suggest a higher threshold, requiring the identification of 20 or more follicles on at least one ovary for a sonographic diagnosis.

Diagnostic Accuracy

Ovarian ultrasound demonstrates impressive diagnostic performance:

• Follicle number per ovary (FNPO): 84% sensitivity, 91% specificity, and an AUC of 0.905.
• Ovarian volume (OV): 81% sensitivity, 81% specificity, and an AUC of 0.856.
• Follicle number per cross-section (FNPS): 81% sensitivity, 83% specificity, and an AUC of 0.870.

Using a threshold of 12 follicles measuring 2–9 mm achieves 99% sensitivity and 75% specificity in differentiating PCOS features. Research applying the Rotterdam criteria has shown improved sensitivity for FNPO, though studies from North America report slightly lower diagnostic accuracy compared to findings from Asia and Europe. These metrics complement earlier biochemical tests, offering a structural perspective on the condition.

Ease of Access

Pelvic ultrasounds are widely available across the U.S., with costs typically ranging from $150 to $500, depending on the facility and expertise of the operator. Antral follicle count (AFC) procedures, another common imaging option, generally cost between $200 and $400. When combined with hormonal markers, these imaging techniques provide a more comprehensive diagnostic approach.

Clinical Applicability

While tests like AMH and serum androgen levels remain essential, ultrasound adds a valuable structural layer to PCOS diagnosis. However, it does have limitations. For example, polycystic-appearing ovaries are common in adolescents, making the method less reliable for younger patients. To address this, the 2023 international evidence-based PCOS guidelines now recommend using AMH levels to define PCOM in adults, reducing some of the challenges associated with ultrasound.

"In our view, the primary advantage to having specific diagnostic criteria for PCOS relates to research, because varying criteria cloud the conclusions and questions the generalizability of results from studies involving women with 'PCOS.' In clinical medicine, simply knowing and understanding the health implications and consequences of chronic anovulation and methods for their effective management are far more important than assigning a specific diagnosis of PCOS…" – Fritz and Speroff

While ultrasound is a helpful tool for confirming a PCOS diagnosis, it cannot definitively rule out the condition. Polycystic ovaries found incidentally do not always indicate PCOS. Additionally, diagnostic thresholds for follicle number may vary by ethnicity, emphasizing the importance of considering patient demographics.

Advantages and Disadvantages

Each diagnostic tool for assessing androgen dysregulation has its own set of strengths and challenges, requiring a tailored approach based on individual needs and clinical scenarios. Here's a closer look at the key tools:

AMH has several benefits. It can be measured at any point in the menstrual cycle and isn't influenced by oral contraceptives. Studies show it has strong diagnostic accuracy for PCOS, performing well across different BMI categories with cut-off values of 5.63 for obese individuals and 5.06 for non-obese individuals. However, its cost (around $90 and not covered by Medicare) and its relatively new status as a biomarker can make interpretation more challenging.

Serum androgens, including testosterone and DHEAS, directly measure hormone levels. Free testosterone, in particular, is more sensitive for detecting androgen excess than total testosterone. However, measuring free testosterone can be complex and results may vary depending on the timing of the test.

LH/FSH ratio is widely available and offers insights into hormonal balance. While it has diagnostic utility, its accuracy is lower compared to AMH and the results can be influenced by the timing within the menstrual cycle.

Ovarian ultrasound allows for direct visualization of ovarian morphology, helping to identify polycystic features. However, its reliability can be affected by operator expertise and imaging challenges, particularly in patients who are obese, virginal, or have poorly echogenic ovaries.

The table below summarizes the key advantages and limitations of each diagnostic method:

A combined approach often enhances diagnostic precision. For instance, combining AMH with antral follicle count yields an AUC of 0.913, which is higher than the 0.901 AUC achieved when combining AMH with LH alone.

In cases where ultrasound is difficult - such as with obese patients, virginal individuals, or those with poor ovarian imaging - AMH offers a dependable alternative. Its ability to be tested at any point in the cycle reduces the need for repeat testing, potentially making it a more practical and efficient choice overall.

Telehealth Solutions for Hormonal Health Management

Telehealth platforms are revolutionizing the way hormonal health is managed, offering faster and more personalized care than ever before. For conditions like PCOS, which sees an average diagnostic delay of 4.3 years, these platforms fill critical gaps in traditional healthcare by streamlining both diagnosis and treatment.

Conclusion

The way we diagnose androgen dysregulation is changing, and Anti-Müllerian Hormone (AMH) is proving to be a game-changer. For years, PCOS diagnosis has relied on tools like serum androgens, LH/FSH ratios, and ovarian ultrasounds. While these methods have their merits, AMH brings something new to the table, particularly in more nuanced or challenging cases.

Research highlights how significant AMH can be: women with PCOS show serum AMH levels two to three times higher than those without the condition (7.34 vs. 2.24 ng/mL). Even better, AMH often outperforms traditional markers in terms of reliability. Dr. Sezai Sahmay from Istanbul University sums it up well:

"Serum AMH measurement is very valuable in the diagnosis of PCOS women. The serum AMH level in women with hyperandrogenism or oligo-anovulation could indicate the diagnosis of PCOS when reliable ultrasonography data are not available or when typical clinical and laboratory findings are not available. The serum AMH level is a new and useful diagnostic tool in PCOS diagnosis."

Combining AMH with other markers like LH/FSH, testosterone, and insulin improves both the accuracy and precision of PCOS diagnoses. This is especially crucial since 80% of PCOS patients have normal LH and LH/FSH ratios. AMH fills in these gaps, offering insights where traditional methods fall short.

What’s more, tailoring AMH thresholds by age enhances its effectiveness. For example, studies suggest thresholds of 8.16 ng/mL for women aged 20–29 and 5.89 ng/mL for those aged 30–39.

Beyond diagnostics, AMH testing is paving the way for more personalized care. Platforms like Oana Health are integrating AMH monitoring into telehealth services, making it easier to deliver tailored treatments remotely. With 75% of employers now emphasizing women’s health in their benefits plans, virtual care solutions that incorporate advanced biomarkers like AMH are becoming increasingly vital. Remote tracking of AMH levels not only personalizes treatment but also addresses the logistical challenges of traditional in-person appointments.

This shift toward integrating cutting-edge biomarkers with modern healthcare delivery systems is reshaping how we approach androgen dysregulation, offering a more accessible and precise path forward.
