📋 Key Information Summary
- Heart disease, lung cancer, suicide, and road-traffic injuries remain the leading causes of death in Australian males across most age groups; suicide is the leading cause of death in men aged 15–44 years (AIHW 2023).
- Australian men die on average 4.1 years earlier than women, with a life expectancy of 81.3 years versus 85.4 years (ABS 2023).
- Androgen deficiency (total testosterone <8 nmol/L or 8–12 nmol/L with symptoms) requires confirmation with an early-morning fasting sample and repeat testing before initiating treatment.
- First-line testosterone replacement is testosterone undecanoate oral (Andriol®) 160–240 mg/day with food, or intramuscular testosterone undecanoate (Reandron 1000®) 1000 mg every 10–14 weeks — PBS Authority Required for confirmed pathological hypogonadism.
- Prostate-specific antigen (PSA) and digital rectal examination (DRE) must be checked before and during testosterone therapy; testosterone is contraindicated in known prostate or breast carcinoma.
- Male osteoporosis accounts for approximately 30% of all fragility fractures in Australia; vertebral fractures in men carry a one-year mortality rate of up to 20%, exceeding that in women.
- DEXA (MBS item 12320) is recommended for men ≥70 years, or ≥50 years with clinical risk factors (glucocorticoid use, hypogonadism, alcohol excess, prior fragility fracture).
- First-line pharmacotherapy for male osteoporosis is alendronate 70 mg PO weekly (PBS authority required); zoledronic acid 5 mg IV annually is an alternative for intolerance or non-response.
- X-linked conditions including haemophilia A (factor VIII deficiency), haemophilia B (factor IX deficiency), Duchenne and Becker muscular dystrophies, red-green colour vision deficiency, and G6PD deficiency predominantly affect males and require early recognition and genetic counselling.
- Carrier testing and prenatal genetic counselling should be offered to at-risk families for all X-linked conditions; referral to a clinical genetics service is available through state-based Genetic Health Services.
- Aboriginal and Torres Strait Islander males have a life expectancy 8.6 years lower than non-Indigenous males; culturally safe, longitudinal primary care engagement is essential to address the burden of chronic disease, mental health, and injury.
Introduction & Australian Epidemiology
Men's health encompasses a broad range of conditions that disproportionately or exclusively affect males across the lifespan. In Australian general practice, men present less frequently than women — on average 30% fewer consultations per year — yet experience higher rates of premature mortality, chronic disease burden, and preventable hospitalisation (AIHW 2023).
The Australian Institute of Health and Welfare (AIHW) reports that males account for 51% of the population but 62% of all deaths. Life expectancy at birth for Australian males is 81.3 years compared with 85.4 years for females (ABS 2023). This gap is driven by cardiovascular disease, cancers (particularly lung, colorectal, and prostate), suicide and self-harm, chronic respiratory disease, and road-traffic injuries.
Key modifiable risk factors include smoking (11.6% of Australian males smoke daily), harmful alcohol consumption (25% exceeding lifetime risk guidelines), physical inactivity (55% not meeting guidelines), overweight and obesity (75% of males with BMI ≥25), and poor mental health help-seeking behaviour (National Men's Health Strategy 2020–2030).
This article provides an overview of four core men's health topics relevant to Australian primary care: causes of death by age group, androgen deficiency, male osteoporosis, and sex-linked inherited disorders.
Main Causes of Death by Age Group — Australian Males
Understanding the leading causes of death at each life stage is essential for targeted preventive health in general practice. The AIHW Burden of Disease and Causes of Death reports provide the most current Australian data.
| Age Group | Rank 1 | Rank 2 | Rank 3 | Key GP Action |
|---|---|---|---|---|
| 0–14 years | Congenital anomalies | Perinatal conditions | Accidents / injury | Newborn screening, child health checks, injury prevention |
| 15–24 years | Suicide & self-harm | Road-traffic injury | Drug-related death | Mental health screening (PHQ-9, K10), HEdS brief intervention |
| 25–44 years | Suicide & self-harm | Drug-related death | Ischaemic heart disease | CVD risk assessment (MBS item 701, 703, 705–707), mental health care plans |
| 45–64 years | Ischaemic heart disease | Lung cancer | Suicide & self-harm | Absolute CVD risk (Framingham), lung cancer screening eligibility, bowel screening |
| 65–74 years | Ischaemic heart disease | Lung cancer | COPD | Smoking cessation, lipid management, spirometry, National Bowel Cancer Screening |
| ≥75 years | Ischaemic heart disease | Dementia / Alzheimer's | Cerebrovascular disease | Stroke risk (CHA₂DS₂-VASc), frailty screening, advance care planning |
Cardiovascular Disease
Ischaemic heart disease is the leading single cause of death in Australian males from age 45 onwards. The National Vascular Disease Prevention Alliance (NVDPA) Absolute Cardiovascular Disease Risk (CVD) Calculator should be used for all men ≥45 years (or ≥30 years for Aboriginal and Torres Strait Islander men). Assessment includes fasting lipids, blood pressure, HbA1c, eGFR, smoking status, and family history (MBS Health Assessment items 701, 703, 705–707).
Cancer
Prostate cancer is the most commonly diagnosed cancer in Australian males (estimated 25,000 new cases in 2023), while lung cancer remains the leading cause of cancer death. Colorectal cancer is the second most common cancer in men; the National Bowel Cancer Screening Program (NBCSP) provides free faecal immunochemical testing (FIT) biennially to Australians aged 50–74. Lung cancer screening with low-dose CT (LDCT) is recommended for high-risk individuals aged 50–74 with ≥20 pack-year smoking history (Cancer Council Australia 2023).
Chronic Respiratory Disease
COPD is the fifth leading cause of death in Australian men. Spirometry is essential for diagnosis in symptomatic patients or those with significant smoking history (≥10 pack-years). Management follows COPD-X guidelines with smoking cessation as the single most effective intervention.
Preventive Health Interventions in General Practice
Androgen Deficiency
Definition and Epidemiology
Androgen deficiency (hypogonadism) is defined biochemically as a sustained reduction in serum testosterone below the normal reference range, associated with characteristic symptoms and signs. The Endocrine Society of Australia and the Australasian chapter of Sexual Health Medicine define androgen deficiency as a total testosterone consistently <8 nmol/L, or 8–12 nmol/L with elevated sex hormone-binding globulin (SHBG) and symptoms consistent with hypogonadism. Prevalence in Australian men aged 40–80 years is estimated at 6–12%, increasing with age, obesity, type 2 diabetes, and chronic illness.
Aetiology
| Category | Examples | Typical FSH/LH |
|---|---|---|
| Primary (hypergonadotropic) | Klinefelter syndrome (47,XXY), bilateral orchitis, testicular torsion, chemotherapy/radiotherapy, cryptorchidism | ↑↑ FSH, ↑↑ LH |
| Secondary (hypogonadotropic) | Kallmann syndrome, pituitary adenoma, hyperprolactinaemia, chronic opioid use, haemochromatosis, obesity-related hypogonadism | ↓ or inappropriately normal FSH/LH |
| Late-onset / age-related | Combined testicular and hypothalamic-pituitary decline; multifactorial with comorbid obesity, T2DM, metabolic syndrome | Variable |
Clinical Presentation
Symptoms are often insidious and non-specific, contributing to under-diagnosis. Key features include:
- Sexual: Reduced libido, erectile dysfunction, reduced frequency of morning erections
- Physical: Fatigue, decreased muscle mass and strength, increased visceral adiposity, reduced body hair, gynaecomastia, hot flushes
- Psychological: Low mood, irritability, poor concentration, reduced motivation
- Reproductive: Infertility, small testes (volume <15 mL on Prader orchidometry)
Diagnostic Approach
Investigations
Testosterone Replacement Therapy
Treatment is indicated only in men with confirmed pathological hypogonadism — not for age-related decline in the absence of symptoms or for the treatment of erectile dysfunction when testosterone levels are normal.
When to Refer
- Suspected secondary hypogonadism requiring pituitary evaluation
- Klinefelter syndrome or other genetic aetiology
- Young men (<40 years) with infertility — testosterone therapy suppresses spermatogenesis; referral to reproductive endocrinology for alternatives (clomiphene, gonadotrophins)
- Persistent symptoms despite adequate testosterone replacement
Osteoporosis in Men
Australian Burden
Osteoporosis is under-recognised in men. Approximately 30% of all fragility fractures in Australia occur in males, yet only 10–20% of men with a hip fracture receive investigation or treatment for osteoporosis (Osteoporosis Australia 2023). One-year mortality following hip fracture is higher in men (33%) than women (20%). An estimated 400,000 Australian men have osteoporosis, and a further 1.5 million have osteopenia (ABS National Health Survey).
Aetiology
Male osteoporosis is classified as:
- Primary: Age-related bone loss (senile osteoporosis) and idiopathic (rare, typically <50 years)
- Secondary: Accounts for 40–60% of cases. Common causes include hypogonadism, glucocorticoid excess (iatrogenic or Cushing's), alcohol excess (>4 standard drinks/day), hypogonadism, chronic liver or kidney disease, hyperparathyroidism, coeliac disease, androgen deprivation therapy for prostate cancer, and smoking
Risk Assessment
DEXA (bone densitometry) is indicated for all men ≥70 years (MBS item 12320). For men aged 50–69 years, DEXA is indicated if one or more clinical risk factors are present:
- Prior fragility fracture (minimal trauma fracture from standing height or less)
- Current or prolonged glucocorticoid use (≥3 months of prednisolone ≥5 mg/day equivalent)
- Hypogonadism (confirmed or on testosterone therapy)
- Hypogonadism secondary to androgen deprivation therapy
- Chronic alcohol excess, rheumatoid arthritis, untreated hyperthyroidism, chronic liver or kidney disease, coeliac disease, primary hyperparathyroidism
- Parental hip fracture history
- BMI <19 kg/m² or significant weight loss
The FRAX® tool (Fracture Risk Assessment Tool) can be used without DEXA for initial risk stratification in men aged 40–90 years, incorporating clinical risk factors to estimate 10-year probability of major osteoporotic fracture and hip fracture.
Pharmacological Management
Non-Pharmacological Measures
- Calcium: Dietary target 1000–1300 mg/day; supplements only if dietary intake inadequate
- Vitamin D: Maintain serum 25(OH)D ≥50 nmol/L. Cholecalciferol 1000–2000 IU daily as supplement; higher loading doses may be required for deficiency (<25 nmol/L)
- Exercise: Weight-bearing and resistance exercise for ≥30 minutes on most days; progressive resistance training improves BMD and reduces fall risk
- Smoking cessation and alcohol moderation
- Fall prevention: Home hazard assessment, balance training, review of medications contributing to falls (sedatives, antihypertensives)
Sex-Linked Inherited Disorders
Sex-linked (X-linked) disorders are caused by mutations on the X chromosome. Because males have only one X chromosome (46,XY), a single pathogenic allele is sufficient to cause disease. Females (46,XX) are usually carriers, though variable X-inactivation (lyonisation) can produce mild or occasionally significant clinical features in carriers. The following conditions are most relevant to Australian primary care.
Haemophilia A and B
| Feature | Haemophilia A | Haemophilia B |
|---|---|---|
| Deficient factor | Factor VIII (FVIII) | Factor IX (FIX) |
| Incidence | ~1 in 5,000 male births | ~1 in 30,000 male births |
| Gene location | Xq28 | Xq27 |
| Severity grading | Severe (<1% FVIII activity), Moderate (1–5%), Mild (5–40%) | Same severity grading by FIX level |
| Presentation | Severe: spontaneous joint/muscle bleeds from infancy; Mild: prolonged bleeding post-surgery/trauma | Similar but generally milder phenotype |
| Diagnosis | Prolonged aPTT, normal PT/INR; low FVIII activity | Prolonged aPTT; low FIX activity |
| Treatment | Factor VIII replacement (recombinant preferred); emicizumab for prophylaxis | Factor IX replacement (recombinant preferred) |
| Haemophilia treatment centres | All Australian states have a Haemophilia Treatment Centre (Australian Haemophilia Centre Directors' Organisation — AHCDO) | |
Duchenne and Becker Muscular Dystrophy
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X-linked recessive disorders caused by mutations in the DMD gene (Xp21.2), encoding dystrophin.
| Feature | Duchenne (DMD) | Becker (BMD) |
|---|---|---|
| Incidence | ~1 in 3,500 male births | ~1 in 18,000 male births |
| Mutation type | Frameshift (out-of-frame deletions/duplications); absent dystrophin | In-frame deletions; reduced or partially functional dystrophin |
| Onset | 2–5 years: delayed walking, Gowers' sign, waddling gait, calf pseudohypertrophy | Variable; may present in childhood or adulthood |
| Ambulation loss | Usually by age 10–12 years | May retain ambulation into adulthood |
| Cardiac involvement | Dilated cardiomyopathy universal by teenage years | Cardiomyopathy in 50–70%; may be presenting feature |
| Diagnosis | CK markedly elevated (10–100× normal); genetic testing (MLPA); muscle biopsy if genetic testing inconclusive | CK elevated; genetic testing confirms |
| Management | Multidisciplinary: corticosteroids (prednisolone 0.75 mg/kg/day or deflazacort), cardiac monitoring, respiratory support, physiotherapy, orthopaedic management. Referral to neuromuscular clinic. | Cardiac surveillance (echo + MRI from diagnosis), physiotherapy, genetic counselling |
Red-Green Colour Vision Deficiency
The most common X-linked condition, affecting approximately 8% of Australian males of European descent and 4–5% overall. It is a benign condition but has implications for occupational requirements (e.g., defence force, aviation, electrical trades). Diagnosis is by Ishihara plates or anomaloscopy. No treatment is available. Genetic counselling is offered for carrier females.
Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency
G6PD deficiency is an X-linked enzymopathy affecting ~400 million people worldwide. Prevalence is highest in people of African, Mediterranean, Middle Eastern, and Southeast Asian descent. In Australia, it is relevant in migrants from endemic regions and in Aboriginal and Torres Strait Islander communities. Affected males are hemizygous; females may be heterozygous carriers with variable enzyme activity.
Clinical features include neonatal jaundice and acute haemolytic anaemia triggered by oxidant drugs (dapsone, primaquine, sulfonamides, rasburicase), fava beans, and infections. Diagnosis is by quantitative G6PD enzyme assay (avoid testing during acute haemolysis as reticulocytes have higher G6PD activity, producing false-normal results). Management is primarily avoidance of triggers. Australian newborn screening does not currently include G6PD, but targeted screening is recommended for at-risk populations.
Genetic Counselling and Referral
- All families affected by X-linked conditions should be offered referral to a Clinical Genetics service (available in all Australian states and territories)
- Carrier testing using molecular genetic analysis should be offered to at-risk female relatives
- Prenatal options include CVS (11–13 weeks), amniocentesis (≥15 weeks), and preimplantation genetic testing (PGT) with IVF
- Newborn screening (heel-prick) does not currently include haemophilia or DMD nationally; clinical suspicion warrants immediate referral
- Genetic counsellors are available through public hospital genetics departments and privately (Human Genetics Society of Australasia — HGSA directory)
Special Populations
Aboriginal and Torres Strait Islander Health Considerations
Aboriginal and Torres Strait Islander males experience a disproportionate burden of disease and premature death across every domain covered in this article. Life expectancy for Indigenous Australian males is approximately 71.6 years — 8.6 years less than non-Indigenous males (AIHW 2023). The gap is greatest in the 35–64 age group, where chronic disease, injury, and mental health conditions converge.
