1. Understanding Testosterone: The Master Hormone

Testosterone in men is crucial for muscle growth and maintenance, bone health, metabolic efficiency, sexual function, mood, and overall vitality (Rojas-Zambrano et al., 2025). Women also require testosterone, albeit in lower concentrations, to support libido, bone strength, mood, and cognitive function. As Derek shared on the How To Increase Your Testosterone Levels Naturally | Derek from MPMD podcast, “Testosterone is the primary anabolic hormone men rely on for the sustainment or growth of muscle tissue, bone health, and inhibiting degradation indirectly through some of those pathways as well, like insulin sensitivity.”

In both sexes, testosterone also acts as a vital precursor for estrogen synthesis, which is essential for reproductive and systemic health. Normative reference ranges differ greatly: men typically range from 264–916 ng/dL, women from 15–46 ng/dL (Rojas-Zambrano et al., 2025).

2. Recognizing Hormonal Imbalance: Symptoms and Challenges

Hormonal imbalances can be subtle or pronounced, often emerging with age, lifestyle stressors, or specific health conditions. Symptoms of suboptimal testosterone in men may include:

• Reduced libido and sexual function

• Loss of muscle mass, strength, or increased body fat

• Fatigue and low energy

• Mood changes, irritability, or depressive symptoms

• Decreased bone density

For women, symptoms can present as low libido, decreased well-being, mood swings, cognitive fog, and bone or joint pain, especially during perimenopause and menopause (Donovitz, 2022).

Challenges in diagnosis include the overlap of symptoms with other medical or lifestyle issues and the natural variability in hormone levels over time. As Derek noted, “It does get tough because, as you would imagine, a lot of the lifestyle-related things that lead to low testosterone will come with a decrement to quality of life just via, you know, if you have poor sleep, you’re not going to feel great… It’s often a constellation of things.” (How To Increase Your Testosterone Levels Naturally | Derek from MPMD)

3. The Science Behind Hormonal Regulation

Testosterone synthesis and function are controlled by the hypothalamic-pituitary-gonadal (HPG) axis, with feedback loops ensuring precise regulation. In men, Leydig cells in the testes produce testosterone; in women, the ovaries and adrenal glands contribute smaller amounts. SHBG (sex hormone-binding globulin) regulates the amount of free, bioactive testosterone available for tissue effects. Both lifestyle and age influence SHBG and testosterone levels, with free testosterone often declining faster than total levels due to rising SHBG as we age (Bhasin, 2021).

For optimal assessment, both total and free testosterone should be evaluated, ideally with morning blood tests and repeat measures. As Derek emphasized, “The two numbers you care about the most are going to be the total testosterone, which is like total production reflection… and free testosterone, about 2 to 3% in an optimally healthy male. That is just freely available to be used.” (How To Increase Your Testosterone Levels Naturally | Derek from MPMD)

4. Personalized Hormone Optimization: Approaches and Key Benefits

Hormone optimization is not a one-size-fits-all process. It requires careful evaluation of symptoms, laboratory values, lifestyle factors, and personal health history. Expert-guided, individualized protocols can include:

• Evidence-based lifestyle interventions (nutrition, exercise, sleep, stress management)

• Targeted supplementation (vitamin D, zinc, magnesium for those deficient)

• Pharmacologic therapies (TRT or HRT) when clinically indicated and symptomatically necessary

Key Benefits of Hormone Optimization:

• Body Composition: Improved muscle mass, strength, and reduced fat mass (Rojas-Zambrano et al., 2025)

• Bone Health: Increased bone mineral density and decreased risk of osteoporosis (Donovitz, 2022)

• Mood and Mental Vitality: Enhanced mood, reduced depressive symptoms, and greater sense of well-being (Bhasin, 2021)

• Sexual Health: Restored libido, improved erectile and sexual function in men and women

• Metabolic & Cardiovascular Health: Better insulin sensitivity, improved lipid profile, and lower risk markers for cardiometabolic disease (Traish et al., 2017)

5. Addressing Unique Challenges for Men and Women

Men experience a gradual decline in testosterone beginning around age 30, with total levels decreasing about 1% per year, and free levels declining even faster due to rising SHBG. Obesity, poor sleep, nutritional deficiencies, alcohol, and stress can further accelerate this decline and blunt hormone action (Almehmadi et al., 2016).

For women, perimenopause and menopause bring marked drops in estrogen and sometimes testosterone, contributing to symptoms such as reduced libido, bone loss, and mood changes. Notably, some forms of oral contraceptives and hormone therapies can suppress free testosterone, intensifying symptoms (Donovitz, 2022). Individualized assessment—considering symptom patterns, risk factors, and personal goals—is essential for both sexes.

6. Latest Research and Current Trends in Hormone Health

Recent studies highlight the importance of long-term, expert-supervised hormone optimization for metabolic and cardiovascular health. For example:

• Long-term testosterone therapy in men with deficiency improves weight, waist circumference, glycemic control, and lipid profiles, and is associated with a lower risk of cardiovascular events (Traish et al., 2017).

• Meta-analyses suggest that testosterone therapy in women with hypoactive sexual desire disorder can improve sexual satisfaction and may benefit bone density, with low rates of significant adverse effects when physiological doses are used (Davis et al., 2019).

Emerging evidence continues to refine the indications, dosing, and monitoring practices for safe and effective hormone therapy. Trends include a shift towards more personalized, data-driven protocols and a recognition of the role of lifestyle optimization in conjunction with (or sometimes instead of) pharmacologic interventions.

7. Risks, Side Effects, and Safety Considerations

While hormone optimization can be transformative, it must be approached with caution. Potential risks and side effects include:

• Polycythemia (increased red blood cells, requiring monitoring)

• Increased risk of sleep apnea

• Acne, hair loss, or mood changes

• Suppressed fertility (especially in men using exogenous testosterone without adjunctive support)

• Potential impact on prostate health in men; rare risk of virilization in women if overdosed

It is essential to work with qualified providers who regularly monitor labs, symptoms, and side effects, adjusting protocols as needed for safety. “When you work with Marek Health, our team will work with you to minimize any side effects through personalized protocols and ongoing monitoring.”

9. Frequently Asked Questions

• Is testosterone optimization safe for everyone?
  Not everyone is a candidate for hormone therapy. Safety depends on individual health status, risk factors, and careful monitoring. Always consult a qualified provider before considering any changes.

• Can women benefit from testosterone optimization?
  Yes, particularly for specific conditions like hypoactive sexual desire disorder or perimenopausal symptoms. Dosing and monitoring are especially important due to the narrow therapeutic window (Davis et al., 2019).

• What lifestyle changes support healthy testosterone?
  Maintaining a healthy weight, regular resistance exercise, balanced nutrition (with adequate protein, healthy fats, and key micronutrients), high-quality sleep, and stress management all support optimal hormone balance.

• Can supplements boost testosterone naturally?
  Correcting deficiencies in vitamin D, zinc, and magnesium may help if you are deficient. Some herbal supplements like ashwagandha or Tongkat Ali show potential, but evidence is mixed and effects are generally modest.

• How often should hormone levels be checked?
  For those on therapy or with symptoms, monitoring every 3–6 months is typical. Your provider will tailor the frequency based on your unique plan and needs.
