When men seek care for hormonal concerns, the conversation almost always centers on testosterone. Low testosterone has become the primary lens through which male hormonal health is discussed, evaluated, and treated in both conventional medicine and the broader wellness space. Testosterone replacement therapy is frequently the first and only intervention offered, and while it produces symptomatic relief for some men, it leaves a significant proportion still struggling with fatigue, low libido, mood changes, body composition shifts, and reduced vitality because the root cause of their hormonal dysfunction was never identified or addressed.
The problem with treating every male hormonal concern as a testosterone deficiency is the same problem that arises when every female hormonal concern is treated as an estrogen problem: it addresses a downstream hormonal measurement without asking why that measurement is where it is, and without evaluating the full hormonal and metabolic picture that determines how a man actually feels and functions. Male hormonal health is more complex than a single hormone level, and understanding that complexity is what makes it possible to get to answers that testosterone replacement alone consistently fails to provide.
Testosterone is an important hormone, and its decline has genuine clinical consequences. But male hormonal health is a system, not a single hormone, and the system involves multiple interconnected players whose balance and function collectively determine how a man feels, functions, and ages.
The hypothalamic-pituitary-gonadal (HPG) axis is the communication pathway that governs testosterone production. The hypothalamus produces gonadotropin-releasing hormone, which signals the pituitary to produce luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which signal the testes to produce testosterone. Disruption at any point in this axis produces downstream effects on testosterone levels and reproductive function. Understanding where in the axis the disruption is occurring is essential for understanding what’s driving the hormonal picture and what addressing it requires.
Estrogen is relevant to male hormonal health in ways that the testosterone-centric conversation frequently ignores. Men produce estrogen through the conversion of testosterone by an enzyme called aromatase, and maintaining an appropriate testosterone-to-estrogen ratio is important for male hormonal health. When aromatase activity is elevated, testosterone converts to estrogen at higher rates, reducing available testosterone and producing elevated estrogen levels that drive symptoms including fatigue, mood changes, reduced libido, increased body fat particularly around the chest and abdomen, and the hormonal picture that many men describe as feeling “off” without being able to identify a clear cause.
According to research published in the Journal of Clinical Endocrinology and Metabolism, estrogen plays important roles in male bone health, cardiovascular function, libido, and cognitive function, and both deficiency and excess are clinically meaningful. The testosterone replacement approach that doesn’t account for estrogen metabolism frequently produces incomplete results or worsens the estrogen picture by providing additional substrate for aromatization.
Cortisol and the HPA axis have direct effects on testosterone production. Cortisol and testosterone share precursor hormones in the adrenal steroidogenesis pathway, and under conditions of sustained cortisol demand, the hormonal pathway shifts toward cortisol production at the expense of testosterone and other sex hormones. According to research published in Psychoneuroendocrinology, chronic psychological stress and HPA axis dysregulation produce measurable reductions in testosterone levels through this pathway, independent of age-related decline. Men whose testosterone has dropped significantly during periods of high stress, sleep deprivation, or sustained physical demand may be experiencing a stress-physiology driven hormonal shift rather than a primary testosterone deficiency.
Thyroid function affects male hormonal health through multiple mechanisms that are rarely evaluated in standard male hormonal workups. Thyroid hormone regulates the metabolic rate of every cell in the body, including Leydig cells in the testes that produce testosterone. Hypothyroidism reduces Leydig cell function and testosterone production, increases sex hormone binding globulin (SHBG) which reduces free testosterone availability, and produces symptoms of fatigue, low libido, mood changes, and body composition shifts that overlap significantly with low testosterone symptoms. According to research published in the International Journal of Endocrinology, thyroid dysfunction is a significantly underdiagnosed contributor to male sexual and hormonal health issues, and addressing it produces improvements in testosterone levels and related symptoms in a meaningful proportion of affected men.
Insulin resistance and metabolic health are central to male hormonal health in ways that standard testosterone evaluation doesn’t assess. Adipose tissue, particularly visceral fat, expresses high levels of aromatase, meaning that as visceral fat increases, testosterone-to-estrogen conversion accelerates. Insulin resistance drives visceral fat accumulation, creating a self-reinforcing cycle where metabolic dysfunction worsens the hormonal picture, and the hormonal dysfunction in turn worsens metabolic function. According to research published in Diabetes Care, insulin resistance and testosterone deficiency co-occur at significantly higher rates than chance would predict, with a bidirectional relationship that makes addressing the metabolic picture an essential component of male hormonal health care.
Testosterone replacement therapy produces symptomatic improvement for a subset of men with genuine testosterone deficiency, and it is an appropriate clinical intervention in specific circumstances. The limitations become apparent when it’s applied as the primary response to male hormonal symptoms without investigating what’s driving the hormonal picture.
When low testosterone is a symptom rather than the primary problem, replacing the testosterone doesn’t address what’s causing it to be low. A man whose testosterone has declined because of HPA axis dysregulation from chronic stress continues to have that stress physiology dysregulation during testosterone replacement. A man whose testosterone is low because of thyroid dysfunction continues to have thyroid dysfunction on testosterone replacement. A man whose testosterone-to-estrogen ratio is unfavorable because of elevated aromatase activity driven by visceral fat and insulin resistance continues to have that metabolic picture.
In each of these cases, testosterone replacement may produce some symptomatic improvement by addressing the hormonal measurement while the underlying driver continues. It does not produce the degree of improvement that addressing the underlying driver would, and it creates a dependency on exogenous hormone replacement that persists indefinitely because the condition driving the deficiency was never resolved.
According to research published in the European Journal of Endocrinology, a significant proportion of men who present with low testosterone have identifiable secondary causes, including lifestyle factors, metabolic dysfunction, thyroid disorders, and HPA axis dysregulation, that when addressed produce meaningful improvement in testosterone levels and associated symptoms without replacement therapy. Identifying those secondary causes requires a more thorough evaluation than measuring a testosterone level and comparing it to a reference range.
Testosterone replacement also suppresses the body’s own testosterone production by providing negative feedback to the HPG axis, which reduces LH and FSH secretion and testicular function over time. For men who might have addressed the secondary cause of their low testosterone and restored normal function, beginning replacement before that investigation has occurred forecloses that possibility and creates a long-term dependency that may have been avoidable.
A root cause approach to male hormonal health begins with a clinical question that standard care rarely asks: why is this man’s hormonal picture the way it is, and what does understanding that make possible?
At True Health Clinic, a male hormonal health evaluation begins with a thorough history that covers the full timeline of when symptoms began and what was happening in the patient’s life at that time, the stress history and current stress load, sleep quality and any sleep disruption patterns, dietary habits and body composition changes over time, exercise patterns and recovery, any significant health changes or medical events that preceded the hormonal symptoms, and the full symptom picture beyond the presenting concern.
The testing ordered reflects what the history and clinical picture suggest is most relevant for that individual. A comprehensive hormone panel that evaluates not just total testosterone but free testosterone, SHBG, LH, FSH, estradiol, DHEA-S, and other markers relevant to the full hormonal picture. A complete thyroid panel with antibody testing that evaluates the thyroid dimension that standard male hormonal workups miss. Metabolic markers that evaluate insulin resistance and the metabolic factors driving aromatase activity and visceral fat accumulation. Cortisol evaluation that assesses the HPA axis pattern relevant to the stress-physiology driven hormonal changes described above. Nutrient status evaluation in areas relevant to testosterone production, including zinc, vitamin D, and magnesium. Inflammatory markers that capture the systemic inflammatory burden affecting hormonal health.
The care plan built from that evaluation addresses the specific combination of drivers identified in that individual’s case. For a man whose primary driver is insulin resistance and visceral adiposity, the most impactful intervention is targeted at the metabolic picture. For a man whose primary driver is HPA axis dysregulation from chronic stress and sleep disruption, the care plan prioritizes stress physiology support and sleep restoration. For a man with thyroid dysfunction contributing to the hormonal picture, addressing the thyroid is a prerequisite for meaningful hormonal improvement. The interventions vary because the drivers vary, and applying the same approach to every man with a low testosterone value produces the same inconsistent results that standard care consistently delivers.
A root cause functional health evaluation for male hormonal issues is particularly valuable for men whose symptoms haven’t responded adequately to testosterone replacement, men who have been told their testosterone is “low normal” and have received no intervention despite ongoing symptoms, men who are reluctant to start testosterone replacement without understanding whether an alternative approach might produce equivalent results without the dependency, and men whose hormonal symptoms are accompanied by other unexplained health changes including fatigue, gut issues, mood symptoms, or body composition shifts that suggest a systemic driver rather than an isolated hormonal deficiency.
It’s also worth pursuing for men who have noticed a significant decline in energy, libido, mood, and vitality over a period of years and want to understand what’s actually driving that decline rather than simply replacing the downstream hormonal measurement it produces.
At True Health Clinic, Dr. Skidmore sees both male and female patients and brings the same thorough, root cause functional health approach to male hormonal health that she brings to every complex hormonal presentation.
