Where is Testosterone Produced?

Introduction: Why Hormonal Health Needs a Functional Approach

Testosterone is more than just a “male hormone”—it plays a critical role in energy, libido, muscle strength, mood, and overall wellness in both men and women. Yet millions live with symptoms of hormonal imbalance, often without realizing it.
At Patients Medical in New York City, we take a root-cause approach to hormone health, including testosterone. We combine functional medicine, advanced diagnostics, and natural therapies to restore balance—not just mask symptoms.

What Is Low Testosterone?

Testosterone is a steroid hormone primarily associated with male sexual characteristics, but it’s vital to many other biological functions. It’s produced in both male and female bodies, though in different amounts.

Where Is Testosterone Produced?
  • In Males: Testosterone is mainly produced in the testes by specialized cells called Leydig cells, regulated by the brain through the hypothalamic-pituitary-gonadal (HPG) axis.

In Females: Small amounts are produced in the ovaries and adrenal glands.
In Both Genders: The adrenal glands (located above the kidneys) also produce a small amount of testosterone.

Common Symptoms of Low Testosterone (Low T)

Testosterone levels decline naturally with age but can also drop prematurely due to stress, toxins, inflammation, and other root causes.
Signs you might have low testosterone include:

Root Causes: Why Do You Have Low Testosterone?

We look beyond numbers to uncover why your testosterone levels are low. Common contributors include:

  • Chronic stress (elevated cortisol suppresses testosterone)
  • Poor liver detoxification
  • Estrogen dominance
  • Leaky gut and microbiome imbalances
  • Nutrient deficiencies (zinc, vitamin D, magnesium)
  • Environmental toxins (BPA, phthalates)
  • Excess alcohol or poor sleep
  • Blood sugar issues or insulin resistance
  • Underactive thyroid function

Advanced Diagnostic Testing We Use

We use comprehensive testing to evaluate your hormone health—not just a single blood test.

Total & Free Testosterone

DHEA, Estradiol, Progesterone

Sex Hormone Binding Globulin (SHBG)

Cortisol (saliva or urine testing)

Comprehensive Thyroid Panel

Vitamin D, Zinc, and Magnesium levels

Heavy metal testing

Leaky gut & microbiome panels

Mitochondrial and adrenal function

Integrative Treatments for Low Testosterone

Nutritional Therapy

We design anti-inflammatory meal plans that support hormone production, blood sugar balance, and detox.

  • Mediterranean or Paleo-style diets
  • Intermittent fasting (when appropriate)
  • Liver support foods (cruciferous vegetables, garlic)
  • Elimination diets to reduce endocrine disruptors

IV Vitamin Therapy

Custom IV infusions to replenish key nutrients and support adrenal and mitochondrial function.

  • B-complex, glutathione, magnesium
  • Alpha-lipoic acid and NAD+

Herbal & Nutraceuticals

Physician-guided supplementation based on labs:

  • Zinc, magnesium, vitamin D3
  • Tribulus terrestris, fenugreek, ashwagandha
  • Tongkat Ali, maca root, and ginseng
  • Omega-3 fatty acids
  • DIM and calcium D-glucarate (for estrogen balance)

Stress Reduction & Hormonal Balance

  • Adaptogens like rhodiola, holy basil, and licorice root
  • Meditation, breathwork, and acupuncture
  • Adrenal glandulars (case-dependent)

Bioidentical Hormone Replacement Therapy (BHRT)

For qualified patients, we may use:

  • Topical or injectable testosterone
  • Bioidentical DHEA or progesteron
  • Tailored doses monitored regularly for safety and effect

Toxin & Gut Repair Protocols

  • Binder therapy for toxins (charcoal, zeolite)
  • Leaky gut repair (L-glutamine, probiotics, DGL)
  • Mold detoxification if indicated

 

Real Case Study: John’s Journey with Low Testosterone

John, Age 49, presented with fatigue, low libido, belly fat, and mood swings. His labs showed low free testosterone, high SHBG, and elevated cortisol. He’d previously been told his levels were “normal.”
We developed a 4-month plan including:

  • Herbal testosterone support
  • Gut-healing protocol
  • Adrenal adaptogens
  • Testosterone cream (BHRT)
  • Weekly nutrient IVs

Results:
By month 4, John reported increased energy, improved libido, sharper focus, and 12 pounds lost—without synthetic drugs.

Frequently Asked Questions

 Symptoms like low libido, fatigue, and muscle loss are clues—but lab testing is essential for confirmation.

 When properly monitored and prescribed, BHRT is safe and highly effective for many men and women.

 Yes. Many patients recover using nutrition, lifestyle, herbs, and targeted supplements.

 Absolutely. Women also need testosterone in small amounts for energy, libido, and mood.

 For many people, yes—especially belly fat and muscle tone improve with hormone balance.

Yes, chronic stress increases cortisol levels, which can suppress testosterone production and exacerbate symptoms of Low T.

Improving diet, exercising regularly, managing stress, getting adequate sleep, and losing excess weight are key lifestyle changes that can support healthy testosterone levels.

TRT is generally safe when monitored by a healthcare provider, but it may have risks, including cardiovascular issues or prostate enlargement. Regular check-ups are important during treatment.

Many men notice improvements in energy, mood, and sexual health within a few weeks of starting testosterone replacement therapy. Full benefits may take a few months.

If left untreated, low testosterone can lead to further complications such as osteoporosis, cardiovascular disease, and diabetes. Early intervention is key to preventing these issues.
