Navigating Hormonal Complexities: Advanced Insights into SHBG, PCOS, PSA, and DHEA

As a practitioner dedicated to integrative wellness, I am Dr. Alex Jimenez. With credentials including DC, APRN, FNP-BC, CFMP, IFMCP, ATN, and CCST, my focus is on integrating the latest evidence-based research into clinical practice to deliver comprehensive care. This educational post will explore several complex yet crucial topics in hormone health. We will delve into the nuances of Sex Hormone Binding Globulin (SHBG), challenging the conventional wisdom that it should simply be lowered. We will then unravel the multifaceted nature of Polycystic Ovary Syndrome (PCOS), discussing its varied presentations and integrative treatment strategies. Following that, we will clarify the best practices for interpreting Prostate-Specific Antigen (PSA) levels to accurately assess prostate cancer risk. Finally, we will highlight the often-underestimated importance of Dehydroepiandrosterone (DHEA) and its role in overall well-being. This journey will be illuminated by findings from leading researchers and grounded in the principles of functional and integrative medicine, including the vital role of chiropractic care in restoring systemic balance.

The Misunderstood Role of Sex Hormone Binding Globulin (SHBG)

In my years of clinical practice, one of the most frequent questions I encounter concerns Sex Hormone Binding Globulin (SHBG). Many practitioners and patients alike believe that the primary goal should be to lower SHBG levels to increase the amount of “free” hormones available to the body. However, I am here to present a more nuanced perspective, supported by robust scientific evidence, that challenges this simplistic view.

Understanding SHBG’s Function

First, let’s understand what SHBG does. Think of it as a transport vehicle. SHBG is a protein produced by the liver that binds to sex hormones—primarily androgens like testosterone, but also estrogens—and carries them through the bloodstream to various cells throughout the body. Once a hormone is bound to SHBG, it is considered inactive. When SHBG arrives at a target cell, it releases the hormone, which then binds to a receptor and becomes active, carrying out its specific function within that cell.

A key point to remember is that SHBG has a higher affinity for androgens than for estrogens. This means it will preferentially bind to testosterone. This is clinically significant. For instance, A patient saw their lab work, where their total testosterone was 130 ng/dL, a level at which they were experiencing symptoms of low testosterone. The reason was a high SHBG level, which was binding up most of their testosterone, leaving very little “free” or bioavailable testosterone to do its job.

Why Lowering SHBG Isn’t Always the Answer

The common impulse is to find ways to lower SHBG. But is that truly beneficial? The research suggests otherwise. In fact, a high SHBG level is often associated with positive clinical outcomes, while low SHBG is a red flag for underlying metabolic issues.

• Low SHBG as a Predictive Marker: Numerous studies have established a strong link between low SHBG levels and a higher risk for cardiovascular disease, metabolic syndrome, and even cardiovascular mortality.
• Insulin Resistance Connection: Low SHBG is a strong predictor of insulin resistance and metabolic dysfunction. We often see a drop in SHBG levels long before we see a rise in Hemoglobin A1c (HbA1c), making it an early warning sign. In my clinical observations, this correlation is undeniable, especially in higher-weight or PCOS patients.
• Increased Diabetes Risk: Research published on this topic has shown that low SHBG is associated with an increased risk of developing type 2 diabetes. One study found that women with low SHBG had an 80% increased risk, while men had a 50% increased risk.

Attempting to artificially lower SHBG can be counterproductive, as the most effective ways to do so—by increasing insulin or estrogen levels—carry significant health risks. Therefore, instead of fighting SHBG, we must learn to work with it.

The Integrative Approach: Saturating the Receptors

The solution isn’t to reduce the number of transport vehicles but to ensure there are enough passengers to go around. The strategy is to saturate the SHBG receptors. By raising total testosterone levels, we can ensure that even after SHBG binds its share, sufficient free testosterone remains to exert its physiological effects. This is why certain supplements, like Shilajit, can be so effective. They help raise total testosterone, which has allowed me to avoid pushing my female patients’ total testosterone levels to excessively high numbers (e.g., 400-450 ng/dL) just to achieve a therapeutic free testosterone level.

It’s also important to be aware of factors that can raise SHBG, such as:

• Certain medications, including oral contraceptives
• Alcohol consumption
• Estrogen therapy

In our practice, as we address underlying metabolic issues and optimize hormone levels, we often see a patient’s initially low SHBG level rise into a healthier range, which is a positive indicator of improved metabolic health.

Demystifying Polycystic Ovary Syndrome (PCOS)

PCOS is one of the most common endocrine disorders in women, yet it is frequently misunderstood and missed. The classic image of a PCOS patient— increased weight, with acne and hirsutism (excess hair growth)—represents only a fraction of those affected.

The Changing Face of PCOS

We now understand that PCOS is a spectrum disorder with different phenotypes. Many women I see do not fit the classic mold. They may be fit, have no acne, and their primary complaint might be infertility or painful, irregular periods.

A recent case from March 20, 2026, involved a 21-year-old, 5’11” collegiate volleyball player. She was incredibly fit, but her labs told a different story. Her Luteinizing Hormone (LH) was nearly triple her Follicle-Stimulating Hormone (FSH), resulting in an LH: FSH ratio much greater than 2:1. Her total testosterone was a seemingly normal 40 ng/dL, but her free testosterone was over 8 pg/mL (well above the reference range high of 4.5), and her SHBG was on the low end of normal. Her chief complaint was debilitatingly painful and irregular periods. She had no hirsutism, hair thinning, or acne. This is a perfect example of a non-traditional PCOS presentation.

Diagnostic Criteria and Underlying Causes

The Rotterdam criteria are used for diagnosis, requiring two of the following three conditions:

1. Oligo-ovulation or anovulation (irregular or absent ovulation) often presents as irregular periods.
2. Hyperandrogenism (high androgen levels), which can be clinical (acne, hirsutism) or biochemical (high free testosterone).
3. Polycystic ovaries on ultrasound (importantly, not all women with PCOS have cysts, and not all ovarian cysts indicate PCOS).

At its core, the primary defect in PCOS is often hyperinsulinemia (high insulin levels) stemming from insulin resistance. This process frequently begins in the gut with dysbiosis (an imbalance of gut bacteria).

The Physiological Cascade:

1. Gut dysbiosis and inflammation contribute to insulin resistance.
2. The pancreas produces excess insulin to compensate (hyperinsulinemia).
3. High insulin levels suppress the liver’s production of SHBG, leading to low SHBG levels.
4. Low SHBG results in higher levels of free, active testosterone.
5. High free testosterone causes the classic symptoms of PCOS, like acne, hirsutism, and hair loss.

An Integrative Treatment Protocol for PCOS

Our treatment approach targets the root causes, not just the symptoms.

• Address the Gut and Insulin Resistance: This is non-negotiable.
  • Metformin: Historically, the go-to, it can be very effective but requires titration up to 2,000 mg/day, which can cause significant GI side effects. It works by lowering insulin levels, which in turn raises SHBG and reduces testosterone hypersensitivity.
  • GLP-1 Agonists: Medications like semaglutide are game-changers for addressing insulin resistance.
  • Nutritional Supplements: I have found supplements containing Akkermansia muciniphila, such as Advaglif Pro, to be incredibly beneficial. Akkermansia is a keystone gut bacterium that has been shown in multiple studies to naturally increase GLP-1 production, supporting metabolic health.
  • Lifestyle: An anti-inflammatory diet and intermittent fasting are powerful tools.
• Manage Androgen Symptoms:
  • Spironolactone: This medication blocks androgen receptors, reducing symptoms like hirsutism and acne. For PCOS, a dose of 100 mg daily is often used. However, it’s crucial to understand that this only masks symptoms; it does not fix the underlying metabolic problem.
• Restore Hormonal Balance and Fertility:
  • By fixing the gut and resolving insulin resistance, we can see a natural resolution of hormonal dysregulation. I had a patient who, after years of struggling with PCOS-related infertility, finally addressed her diet, gut health, and hormones. It took three years for her ovulation to normalize, but she successfully conceived at 37 and then again, unexpectedly, a year later. It works.
  • Chiropractic Care: As an integrative practitioner, I find that chiropractic adjustments are essential. Spinal misalignments, or subluxations, can interfere with the nerve supply to the endocrine glands and digestive organs. By restoring proper neurological function, we support the body’s innate ability to regulate hormones and improve gut health, which are central to managing PCOS.

The Importance of Free PSA in Prostate Health

Prostate-Specific Antigen (PSA) screening guidelines have shifted over the years, creating confusion for both clinicians and patients. Relying solely on the total PSA number is insufficient for accurately assessing prostate cancer risk.

Beyond Total PSA: The Role of Free PSA

We must also look at the percent-free PSA. PSA exists in the blood in two forms: bound to proteins and “free” (unbound).

• The Rule: There is an inverse relationship. A low percent-free PSA in the context of an elevated total PSA indicates a higher risk for prostate cancer.
• Velocity Change: Another critical metric is the year-over-year change in PSA. A rapid increase (e.g., more than 2.0 ng/mL in one year) is a major red flag for aggressive cancer, even if the total PSA remains within the “normal” range.

Practical Guidelines for PSA Interpretation

To streamline this process, here are the guidelines we use in our practice:

1. Reflex Testing: We set up our lab accounts to automatically run a percent-free PSA test if the total PSA comes back greater than 4.0 ng/mL. This avoids a second blood draw.
2. Interpreting the Results:
   • Free PSA > 20%: Very low likelihood of cancer. We re-check in a few months.
   • Free PSA 10-20%: Intermediate risk. We may treat for prostatitis (a common cause of elevated PSA) if symptomatic and then retest.
   • Free PSA < 10%: High likelihood of cancer (>50%). This warrants further investigation.

The Next Step: Prostate MRI

Before referring a patient for an invasive biopsy, our gold standard next step is a 3-Tesla multi-parametric prostate MRI. This advanced imaging can:

• Detect and characterize lesions with high accuracy.
• Confirm the presence of acute or chronic prostatitis, often the real cause of an elevated PSA.
• Provide peace of mind and help avoid unnecessary biopsies. Nine out of ten men would prefer an MRI to a biopsy.

It is crucial to hold off on testosterone therapy for any patient with a suspicious PSA profile until prostate cancer has been definitively ruled out.

DHEA: The Overlooked Neurosteroid

Finally, let’s discuss Dehydroepiandrosterone (DHEA), a vital hormone produced by the adrenal glands and, to a lesser extent, the central nervous system. I often see patients who, despite having optimized testosterone levels, still complain of low libido, depression, and cognitive fog. Very often, the culprit is low DHEA.

Why DHEA Matters

DHEA is classified as a neurosteroid because it has independent receptors in the brain. Its age-related decline, which begins in our 30s, can profoundly affect well-being, mood, and cognitive function. Low DHEA is also linked to a host of health issues, including inflammation, atherosclerosis, and poor bone density.

In women, DHEA is a significant precursor to androgens, converting readily to DHT, which plays a major role in libido and sexual function. Supplementing with DHEA can often be the missing piece for women who don’t respond fully to testosterone therapy alone.

Dosing and Considerations for DHEA

• Optimal Levels: Like with other hormones, we aim for the upper quartile of the lab reference range, not just the “average.”
• Supplementation: If a patient’s DHEA is in the double digits, I will treat them from the outset. I prefer using compounded, prescription-grade DHEA over over-the-counter supplements, which are unregulated and often less effective. In most countries outside the US, DHEA is a prescription medication, which speaks to its potency.
• Starting Doses: A typical starting dose is 5-10 mg for females and 20 mg for males, with levels rechecked after about six weeks.
• Contraindications: We do not give DHEA to patients with PCOS, as they typically have elevated DHEA levels.

By integrating these advanced diagnostic and treatment strategies, we can move beyond a one-size-fits-all approach and provide truly personalized, effective care that addresses the root causes of hormonal imbalance and promotes lasting health and vitality.
