Men in the United States die, on average, about five years earlier than women. They are significantly less likely to visit a doctor for preventive care, more likely to be diagnosed with a serious condition at a later stage, and less likely to discuss symptoms — physical or mental — before they become urgent. These patterns are not inevitable. They are, in large part, the product of cultural norms around masculinity, self-sufficiency, and a healthcare system that has historically been better at treating illness than supporting the conditions for men to seek help before it arrives.
Men’s Health Month, observed every June, is a dedicated opportunity to shift that dynamic. It is a moment to normalise preventive screening, reduce the stigma that keeps men out of clinical settings, and build the kind of health literacy that supports better long-term outcomes — not just for men, but for the families and communities that depend on them.
Central to that literacy is understanding biomarkers: the measurable indicators in blood and other biological samples that reflect how key systems in the body are functioning. Knowing what PSA measures, why a lipid panel matters, or what HbA1c reveals about metabolic health gives men a factual foundation for the conversations they have — or have not yet started — with their healthcare providers.
Why Men’s Health Month Matters
The Life Expectancy Gap
The five-year life expectancy gap between men and women in the United States is not explained by biology alone. Men are significantly more likely to die from heart disease, cancer, stroke, diabetes, and suicide — all conditions with well-characterised risk factors and, in many cases, measurable early signals that can support earlier clinical attention.
According to the CDC, heart disease remains the leading cause of death for men in the U.S., accounting for roughly one in four male deaths. Prostate cancer is the most common non-skin cancer among American men, with approximately one in eight men diagnosed during their lifetime. Type 2 diabetes and its precursor, insulin resistance, affect millions of men — many undiagnosed. These are not conditions without warning. They develop over years, and the biological changes that precede symptoms can often be observed in routine laboratory tests long before a crisis presents.
Barriers to Preventive Care
Understanding why men avoid preventive care is not a matter of finding blame — it is a practical prerequisite for reducing those barriers. Research consistently identifies several contributing factors: a cultural emphasis on stoicism and self-reliance that frames help-seeking as weakness; practical barriers including work schedules, cost, and geographic access; and a perception that clinical appointments are something one does when something is already wrong, not as a regular maintenance practice.
Direct-to-consumer lab testing has emerged as a meaningful bridge for some men in this situation — offering a private, convenient, and accessible entry point to health data that does not require navigating a clinical appointment. The goal is not to circumvent medical care, but to lower the activation energy required to start engaging with it.
The Most Common Health Risks Facing Men
Prostate Health
The prostate is a small gland in the male reproductive system that tends to receive limited attention until symptoms develop. Prostate cancer is the second leading cause of cancer death among American men, after lung cancer, though many cases are slow-growing and may not pose an immediate threat to life. Benign prostatic hyperplasia (BPH) — a non-cancerous enlargement of the prostate — is also extremely common, affecting the majority of men to some degree by their 70s and causing urinary symptoms including increased frequency, weak flow, and difficulty fully emptying the bladder.
Prostate health is one area where routine screening has a clear role and a clear biomarker associated with it.
Heart and Metabolic Disease
Cardiovascular disease and metabolic conditions — including obesity, insulin resistance, and type 2 diabetes — share a common biological terrain in many men: excess visceral adiposity, chronic low-grade inflammation, dyslipidaemia (abnormal cholesterol and triglyceride levels), and dysregulated blood glucose. These conditions often develop together and reinforce one another, collectively described as metabolic syndrome when several are present simultaneously.
Men are, on average, more susceptible to cardiovascular events at a younger age than women, with risk rising sharply after 45. Yet many men in their 30s and 40s have never had a basic lipid or glucose assessment — the simplest starting points for understanding metabolic cardiovascular risk.
Hormonal Health and Testosterone
Testosterone is the primary male sex hormone, and its role extends well beyond reproductive function. It influences muscle mass, bone density, fat distribution, energy, mood, libido, and cognitive function. Testosterone levels in men begin a gradual natural decline from the mid-30s onwards — typically around 1–2% per year — though the rate and extent of decline vary considerably between individuals.
Low testosterone, sometimes referred to clinically as hypogonadism, is associated with symptoms including persistent fatigue, reduced libido, erectile difficulties, decreased muscle mass, increased body fat (particularly abdominal), low mood, and difficulty concentrating. These symptoms are nonspecific — they overlap with many other conditions — which is why laboratory measurement is an important part of any evaluation of suspected hormonal changes.
Mental Health Considerations
Men are significantly less likely than women to seek help for mental health concerns, and significantly more likely to die by suicide — at a rate approximately four times higher in the United States. Depression in men frequently presents differently than clinical descriptions suggest — more often as irritability, withdrawal, increased risk-taking, or substance use than as expressed sadness.
While mental health is not a biomarker-driven domain in the same way as cardiovascular or metabolic health, there are meaningful physiological connections. Chronic inflammation, low testosterone, thyroid dysfunction, and poorly controlled blood glucose have all been associated with depressive symptoms in men. Understanding one’s physical health markers is therefore not separate from mental wellbeing — it is part of the same picture.
Key Biomarkers Every Man Should Understand
PSA — Prostate Health Marker
Prostate-specific antigen (PSA) is a protein produced by prostate tissue and secreted into the bloodstream in small amounts. PSA levels can be elevated by a range of conditions affecting the prostate — including benign enlargement, prostatitis (inflammation of the prostate), and prostate cancer. An elevated PSA does not confirm cancer. Similarly, a normal PSA does not entirely exclude it.
PSA testing is typically considered from age 50 for men at average risk, and from age 40–45 for men with a family history of prostate cancer or those of African American descent, who face a higher risk of developing the disease at a younger age. The decision to screen with PSA should involve a conversation with a healthcare provider about the benefits and limitations of the test, including the possibility of false-positive results and the implications of further investigation.
PSA is most informative when tracked over time. A single reading provides context; a series of readings over years — revealing how PSA changes, and at what rate — gives a more nuanced picture that supports more informed clinical decision-making.
Testosterone — Hormonal Balance
A blood test measuring total testosterone reflects the overall concentration of testosterone in the bloodstream. Free testosterone — the fraction not bound to carrier proteins and therefore biologically active — is also measurable and can provide additional context when total testosterone is borderline or when symptoms suggest hormonal imbalance despite a normal total level.
Testosterone levels vary significantly between individuals and fluctuate throughout the day — typically peaking in the morning, which is why testing is generally recommended in the early morning hours for the most accurate baseline reading. Reference ranges vary between laboratories, and what constitutes clinically low testosterone requires interpretation alongside symptoms and overall clinical context.
Understanding where one’s testosterone sits relative to normal ranges — and how it changes over years — is a useful component of men’s health monitoring, particularly for men in their 40s, 50s, and beyond.
Lipid Panel — Cardiovascular Risk
The lipid panel measures several distinct components of blood fat that are independently relevant to cardiovascular risk.
Low-density lipoprotein (LDL) cholesterol is associated with the deposition of fatty plaques in arterial walls and is a primary driver of atherosclerosis. Elevated LDL is one of the most modifiable cardiovascular risk factors through both lifestyle and, when indicated, medical management.
High-density lipoprotein (HDL) cholesterol is often described as the “protective” form — it is associated with the transport of cholesterol away from arterial walls. Higher HDL levels are generally associated with lower cardiovascular risk.
Triglycerides are a type of blood fat stored in fat cells and used for energy. Elevated triglycerides are associated with metabolic syndrome, insulin resistance, and cardiovascular risk, particularly when combined with low HDL.
Together, these markers provide a starting point for understanding cardiovascular risk that is far more actionable than any symptom. Many men with significant dyslipidaemia feel entirely well — the lipid panel brings what is otherwise invisible into view.
HbA1c — Blood Sugar Trends
Haemoglobin A1c (HbA1c) reflects average blood glucose levels over the preceding two to three months. Unlike a fasting glucose test, which captures a single point-in-time reading, HbA1c provides a broader temporal picture of how blood sugar has been running.
An HbA1c in the normal range (below 5.7% in most guidelines) indicates well-regulated blood glucose. The prediabetes range (5.7–6.4%) reflects persistently elevated blood sugar that has not yet crossed the threshold for a type 2 diabetes diagnosis but represents meaningful metabolic risk. A result at or above 6.5% on two separate occasions is consistent with a diabetes diagnosis under standard clinical criteria — though diagnosis requires physician confirmation.
For men in their 40s and 50s with excess weight, family history of diabetes, or a sedentary lifestyle, HbA1c monitoring is a practical way to track metabolic health over time and identify trends before they become clinically significant.
CRP — Inflammation and Heart Health
C-reactive protein (CRP), particularly measured via the high-sensitivity assay (hs-CRP), serves as a marker of systemic inflammation. Chronic low-grade inflammation is increasingly recognised as a contributing factor to cardiovascular disease, atherosclerosis, and metabolic dysfunction — not just a downstream consequence of them.
In the context of men’s cardiovascular health, hs-CRP is used alongside traditional lipid markers to provide a more complete picture of risk. Men with normal or near-normal LDL but elevated hs-CRP may still carry meaningful cardiovascular risk that would not be apparent from lipid data alone. CRP is also influenced by lifestyle factors — body weight, physical activity, smoking, and dietary patterns all affect baseline inflammation levels — making it a useful marker to track in response to health behaviour changes over time.
What These Biomarkers Can (and Cannot) Tell You
Screening vs. Diagnosis
A recurring theme across biomarker education — and one worth stating plainly in the context of men’s health — is that screening markers identify individuals who may benefit from further evaluation. They do not provide diagnoses.
An elevated PSA does not mean prostate cancer. A low testosterone level does not automatically indicate hypogonadism requiring treatment. A high LDL number is a risk signal, not a guaranteed predictor of a heart attack. Each of these results initiates a process of further investigation and clinical interpretation, not a conclusion.
Understanding this distinction helps men engage with biomarker results confidently rather than anxiously — as data to work with, not verdicts to fear.
Monitoring Trends Over Time
The most clinically meaningful approach to biomarker data is longitudinal. A PSA reading at age 45 and again at 48 and 51 tells a richer story than any single value. HbA1c tracked annually over a decade reveals metabolic trajectory. Testosterone measured at regular intervals provides a personal baseline that makes any meaningful change easier to detect and contextualise.
For men who have historically avoided regular testing, establishing a baseline now — whatever age that is — creates a foundation for all subsequent data. A number without context is a snapshot; a series of numbers over time is a story that supports genuinely informed healthcare conversations.
Who Should Consider Regular Biomarker Screening
Men Over 40
The risk profiles for cardiovascular disease, prostate cancer, metabolic dysfunction, and hormonal decline all shift meaningfully in the decade from 40 to 50. For men without established medical conditions who have not been recently screened, this decade is the most practical starting point for building a biomarker baseline. At minimum, a lipid panel, fasting glucose or HbA1c, and a conversation about PSA screening are widely recommended by preventive health guidelines for men in this age range.
Family History of Prostate or Heart Disease
A first-degree relative — father or brother — with prostate cancer is associated with roughly twice the average population risk, and some hereditary prostate cancer syndromes carry considerably higher risk. Premature cardiovascular disease in a male first-degree relative (before age 55) is among the strongest risk factors for cardiovascular events in men. For both conditions, family history makes earlier and more regular biomarker monitoring particularly relevant.
Men Experiencing Fatigue or Metabolic Changes
Persistent unexplained fatigue, increasing difficulty managing weight despite no obvious change in lifestyle, declining exercise performance, changes in libido, or new difficulty concentrating are all symptoms that may have measurable physiological underpinnings. Rather than attributing these changes to ageing and moving on, men experiencing them have good reason to investigate their biomarker profile — including testosterone, thyroid function, HbA1c, CRP, and a full metabolic panel — as a starting point for a productive clinical conversation.
Taking Ownership of Your Health Data
How Direct-to-Consumer Testing Works
Direct-to-consumer lab testing gives men access to a broad range of health biomarkers without requiring a referral or a clinical appointment. After selecting a panel, blood is collected at a certified local laboratory and results are typically available through a secure digital platform within a few days.
For men who have been putting off a check-up — whether due to time, cost, geography, or simple avoidance — DTC testing offers a lower-barrier starting point. It is private, convenient, and focused on data rather than diagnosis. Men can access their own numbers, understand what they mean in general terms, and use that information as both motivation and preparation for a clinical conversation.
It is important to be clear about what DTC testing is not. It does not replace a physician’s evaluation. Biomarker results exist within clinical context — the history, symptoms, physical examination, and professional judgment that a healthcare provider brings to their interpretation. A DTC result is a data point, not a clinical conclusion. For any result that raises questions, follow-up with a healthcare provider is the appropriate next step.
Tracking Your Biomarkers Year Over Year
The investment of annual biomarker testing becomes increasingly valuable over time. Year-over-year tracking of PSA, testosterone, lipid levels, HbA1c, and CRP builds a personal health record that is genuinely informative — revealing trends, flagging changes, and establishing the kind of individual baseline that makes any significant shift meaningful rather than ambiguous.
Men who engage with their health data consistently are better positioned to notice when something is changing, to have more specific conversations with their doctors, and to make lifestyle decisions informed by measurable feedback rather than assumption. That is what biomarker ownership looks like in practice.
Turning Awareness Into Action This June
Men’s Health Month carries a straightforward message: the conditions most likely to cut men’s lives short are, in many cases, measurable and preventable. Not all of them — but enough that the gap between men who engage proactively with their health and those who do not represents real, recoverable years.
The cultural shift required to close that gap will not happen overnight. But it does not require a revolution in attitudes to take a practical step this June. Know your PSA status if you are 40 or older with a family history, or 50 without one. Get a lipid panel if you have not had one in the last five years. Check your HbA1c if metabolic health is a concern. Have your testosterone measured if fatigue, low mood, or hormonal changes have been on your mind.
These are not dramatic interventions. They are the foundation of a relationship with your own biology — one that can support better decisions, earlier conversations, and a more complete picture of what long-term health actually looks like for you.
