Men’s Health, Testosterone Therapy and Functional Medicine
Low testosterone is rarely just a testosterone problem.
At Will Koopal Functional Medicine, I evaluate men’s hormones through a comprehensive functional medicine approach. That means looking beyond testosterone alone and considering the full picture, including lifestyle, sleep, stress, gut health, inflammation, insulin resistance, thyroid function, immune health, nutrient status, muscle mass, body composition, mental, emotional and spiritual health and long-term function.
Testosterone replacement therapy, or TRT, may be appropriate for some men. But the best outcomes often come from understanding why the hormone imbalance developed and what other systems need support.
The goal is not simply to improve a lab number. The goal is to understand why you feel the way you do and build a plan that supports energy, strength, metabolism, sexual health, and long-term function.
Testosterone does not function in isolation.
A man’s hormone health may be affected by:
Poor sleep
Sleep apnea
Chronic stress
Alcohol use
Insulin resistance
Abdominal fat
Gut inflammation
Nutrient deficiencies
Poor protein intake
Overtraining
Under-recovery
Chronic infections
Environmental toxins
Thyroid dysfunction
Inflammation
Emotional stress
Loss of purpose or burnout
If these issues are ignored, TRT may not produce the desired outcome.
A functional medicine approach asks: What is driving the hormone imbalance, and how do we support the whole system?
What Sets This Apart?
All new patients begin with a Discovery Session.
This first appointment allows me to better understand your health history, symptoms, lifestyle, previous labs, goals and the factors that may be contributing to fatigue, low libido, poor recovery, body composition changes or other hormone-related concerns before recommending a care path.
Your Discovery Session may help determine whether the next step includes further investigation, lifestyle strategies, functional or conventional lab testing, TRT, peptide therapy, gut testing, metabolic support or another personalized treatment option.
New Patients Start With a Discovery Session
Men’s hormone care may be a good fit for those experiencing:
Fatigue or low energy
Low motivation
Low libido
Erectile changes
Loss of muscle mass
Increased abdominal fat
Brain fog
Mood changes or irritability
Poor sleep
Reduced exercise recovery
Decreased strength
Depression-like symptoms
Weight gain
Poor metabolic health
Low confidence
Symptoms of low testosterone
Interest in testosterone replacement therapy, or TRT
These symptoms can overlap with many other conditions, including sleep apnea, thyroid dysfunction, insulin resistance, depression, chronic stress, gut inflammation, nutrient deficiencies, medication effects and unresolved emotional stress.
That is why a comprehensive evaluation matters.
Who is This For?
Low testosterone symptoms are often signals from a larger system. All new patients begin with a Discovery Session, where we take time to understand your health history, symptoms, lifestyle, labs, and goals before determining the most appropriate next step for your care.

Understanding Men’s Hormone Health
Men’s hormone health is influenced by more than testosterone alone. Testosterone interacts with sleep, stress, gut health, inflammation, immune function, thyroid function, blood sugar, insulin resistance, detoxification, muscle mass, body composition, cardiovascular health and mental, emotional and spiritual well-being.
Use the sections below to learn more about how these systems may affect low testosterone symptoms, TRT, sexual health, energy, recovery, metabolism and long-term function.

Perimenopause can begin years before menopause. During this time, estrogen and progesterone may fluctuate unpredictably. Some women continue having regular periods but begin experiencing symptoms that feel confusing, frustrating or even alarming.
Common perimenopause symptoms may include:
Irregular periods
Heavier or more painful periods
Hot flashes
Night sweats
Poor sleep
Mood swings
Anxiety or irritability
Brain fog
Fatigue
Weight gain, especially around the abdomen
Low libido
Vaginal dryness
Joint pain
Headaches
PMS changes
Reduced exercise recovery
Loss of muscle tone
Increased inflammation or sensitivity to stress
Many women say, “I just don’t feel like myself.”
I take that seriously.
Perimenopause is not just a reproductive transition. It is also a metabolic, neurological, inflammatory and musculoskeletal transition.
That is why I evaluate hormones alongside gut health, thyroid function, insulin, cortisol rhythm, inflammation, nutrition, sleep, muscle mass and bone density before recommending a care path.
-
Menopause is defined as 12 consecutive months without a menstrual period. But the effects of menopause extend far beyond the menstrual cycle.
Declining estrogen and progesterone may contribute to:
Hot flashes and night sweats
Sleep disruption
Mood changes
Brain fog
Vaginal dryness
Urinary changes
Pain with intercourse
Low libido
Loss of muscle mass
Increased abdominal fat
Changes in cholesterol
Bone density loss
Joint discomfort
Skin and hair changes
Reduced stress resilience
Menopause is not a disease. But it is a major health transition.
For many women, this is the ideal time to evaluate the foundations of long-term health: hormones, muscle, bone, metabolism, gut health, inflammation, detoxification, sleep and emotional resilience.
-
BHRT, or bioidentical hormone replacement therapy, refers to hormones that are chemically identical to hormones naturally produced by the body.
At Will Koopal Functional Medicine, hormone therapy may include, when appropriate:
Estradiol
Bi-est
Progesterone
Testosterone
DHEA
I do not offer hormone pellet therapy.
Instead, I use individualized non-pellet approaches depending on your symptoms, labs, health history, risk factors, goals and clinical needs.
Hormone therapy is not one-size-fits-all. Some women may benefit from BHRT, while others may need to first address inflammation, gut health, detoxification, insulin resistance, thyroid function, nutrient status or stress physiology before hormones are introduced or adjusted.
The goal is not simply to prescribe hormones. The goal is to create the internal environment where hormones can be used safely, thoughtfully and effectively as part of a comprehensive plan.
-
Gut health plays a major role in women’s hormone health.
One important concept is the estrobolome, which refers to the collection of gut bacteria involved in estrogen metabolism. The gut helps influence how estrogen is processed, recirculated and eliminated from the body.
When gut health is disrupted, estrogen metabolism may also be affected.
Factors that can influence the estrobolome include:
Dysbiosis
Constipation
Poor bile flow
Low fiber intake
Chronic inflammation
Gut infections
Antibiotic history
Nutrient deficiencies
Liver detoxification burden
Elevated beta-glucuronidase activity
Beta-glucuronidase is an enzyme produced by certain gut bacteria. When elevated, it may contribute to estrogen being reactivated and recirculated rather than properly eliminated.
This is one reason gut testing may be helpful in selected patients. At Will Koopal Functional Medicine, I may use advanced testing such as the GI-MAP to evaluate gut health, microbial balance, inflammation markers, digestive function and beta-glucuronidase activity when clinically appropriate.
The gut, brain, immune system and hormones are deeply connected.
-
Inflammation can come from many sources. It may be influenced by:
Poor sleep
Chronic stress
Gut dysfunction
Food sensitivities
Insulin resistance
Environmental toxins
Autoimmune activity
Chronic infections
Overtraining
Under-recovery
Nutrient deficiencies
Emotional stress
Poor mitochondrial function
A helpful way to think about inflammation is like a cup. Each stressor adds more water to the cup. Eventually, the cup overflows and symptoms appear.
For some women, the overflowing cup looks like fatigue. For others, it looks like weight gain, joint pain, brain fog, anxiety, hot flashes, poor sleep, hormone sensitivity or poor recovery.
This is why I often work to lower inflammation and improve foundational health before or alongside hormone therapy.
When the system is less inflamed and more resilient, hormone therapy may be better tolerated and more effective for appropriate candidates.
-
Chronic stress can profoundly influence hormone health.
Some people refer to this as “cortisol steal,” describing the way chronic stress may shift the body’s priorities toward survival physiology rather than optimal reproductive, thyroid, metabolic or repair function.
From a functional medicine perspective, I look at the broader HPA axis, which includes communication between the brain, adrenal glands, cortisol rhythm, nervous system, blood sugar, sleep and inflammation.
Chronic stress may contribute to:
Poor sleep
Anxiety
Fatigue
Blood sugar swings
Cravings
Low libido
Irregular cycles
Thyroid changes
Inflammation
Poor recovery
Hormone imbalance symptoms
Mental, emotional and spiritual health are not separate from hormone care. They are part of hormone care.
A comprehensive hormone plan may include nervous system support, boundaries, sleep restoration, breathwork, prayer or spiritual practices, counseling support, mindfulness, connection, movement and other personalized strategies that help restore resilience.
-
Hormone health is closely connected to muscle and bone health.
As women move through perimenopause and menopause, declining estrogen and other hormonal changes can contribute to changes in:
Muscle mass
Strength
Bone density
Fat distribution
Insulin sensitivity
Balance
Recovery
Long-term mobility
Sarcopenia
Sarcopenia refers to the loss of muscle mass and strength that can occur with aging. It is not just a cosmetic issue. Muscle is a metabolic organ.
Healthy muscle supports:
Blood sugar regulation
Metabolism
Strength
Balance
Bone health
Hormone sensitivity
Mobility
Longevity
Injury prevention
A woman can maintain the same weight but lose muscle and gain fat. This is why body composition often matters more than weight alone.
Osteopenia and Osteoporosis Risk
Estrogen plays an important role in bone remodeling. As estrogen declines, some women experience accelerated bone loss, which can lead to osteopenia or osteoporosis.
A DEXA scan can help evaluate bone mineral density and may also provide valuable body composition data depending on the scan type.
At Will Koopal Functional Medicine, I view DEXA results through a broader functional lens. Bone health may be influenced by:
Estrogen status
Progesterone balance
Testosterone levels
Vitamin D
Calcium and mineral status
Protein intake
Resistance training
Gut absorption
Inflammation
Thyroid function
Medications
Family history
Menopause timing
Alcohol and tobacco exposure
Muscle mass
A strong midlife women’s health plan should include both hormone evaluation and muscle and bone preservation.
Men’s Hormone Health FAQ
-
BHRT stands for bioidentical hormone replacement therapy. It refers to hormones that are chemically identical to hormones naturally produced by the body, such as estradiol, progesterone, testosterone and DHEA.
-
BHRT may help some women with symptoms such as hot flashes, night sweats, sleep disruption, mood changes, vaginal dryness, low libido and quality-of-life concerns. Treatment should be individualized based on health history, symptoms, labs, risk factors and goals.
-
No. Hormone therapy is not appropriate for everyone. Some women may benefit from lifestyle, nutrition, gut support, resistance training, sleep optimization, metabolic care or non-hormonal options. Treatment should be individualized.
-
The gut microbiome helps influence estrogen metabolism through the estrobolome. Gut inflammation, dysbiosis, constipation and elevated beta-glucuronidase may affect estrogen clearance and hormone balance.
-
Beta-glucuronidase is an enzyme produced by certain gut bacteria. When elevated, it may contribute to estrogen being reactivated and recirculated rather than properly eliminated.
-
The DUTCH test is a dried urine test that may provide information about hormone metabolites, cortisol rhythm and hormone clearance patterns. It may be used when clinically appropriate.
-
The GI-MAP is a stool test that evaluates aspects of gut health, including microbial patterns, inflammation markers, digestive function and beta-glucuronidase activity.
-
DEXA scans measure bone density and may help identify osteopenia or osteoporosis risk. Hormonal changes during menopause can affect bone density, making DEXA data valuable in long-term women’s health planning.
-
Sarcopenia is the loss of muscle mass and strength that can occur with aging. Hormonal changes, low protein intake, poor sleep, inflammation and lack of resistance training may contribute.
-
Testing is not about collecting data for the sake of data. It is about understanding your pattern so the plan can be more precise.
Depending on your needs, advanced testing may include:
Comprehensive bloodwork
Estradiol
Progesterone
Testosterone
Free testosterone
SHBG
DHEA-S
Thyroid panel
Fasting insulin
Glucose
Hemoglobin A1c
Lipids
Vitamin D
CBC/CMP
Inflammatory markers
Iron/ferritin
DEXA scan
GI-MAP testing
DUTCH testing
-
In some cases, peptide therapy may be considered as an additional tool alongside hormone optimization, lifestyle changes, gut support, nutrition, and functional medicine care.
Peptides are not a shortcut or a replacement for foundational health. I still want to understand the full picture first — your symptoms, health history, goals, labs, lifestyle, and whether peptide therapy is clinically appropriate for you.
When used, peptides are part of a broader plan that may support:
Recovery
Inflammation
Body composition
Metabolic health
Tissue repair
Sleep
Resilience
Like everything else in functional medicine, peptide therapy is highly individualized and should be discussed as part of your overall care plan.
At Will Koopal Functional Medicine, I do not believe men should be rushed into testosterone therapy or treated based on one lab value alone.
Low testosterone symptoms matter, but they deserve a deeper look. Testosterone is important, but it is only one part of the picture. I also consider estradiol, DHEA, cortisol rhythm, thyroid function, gut health, inflammation, immune function, insulin resistance, muscle mass, body composition, sleep, nutrition, stress physiology, and mental, emotional, and spiritual well-being.
My training includes certification through the Institute for Functional Medicine Certified Practitioner program, a multi-year process with in-depth coursework across the major systems represented in the functional medicine matrix, including hormones, gut health, immune function, detoxification, cardiometabolic health, energy, and more.
Additional hormone-focused training through organizations such as A4M has further informed my approach to men’s and women’s hormone optimization.
This background helps me evaluate hormones as part of the whole person — not as isolated lab values.
