Men Get Osteoporosis, But the Journey is Different
It is a persistent myth that osteoporosis is exclusively a "woman's disease." While women do have a higher prevalence, roughly one-quarter of all fractures in people over 50 occur in men. The underlying reasons for the differences in prevalence and progression between the sexes are rooted in biology, hormones, and lifestyle factors. Men's larger skeletal size and distinct hormonal aging process provide a protective advantage, but this does not grant immunity from bone loss.
The Role of Peak Bone Mass and Skeletal Size
One of the most significant protective factors for men is their higher peak bone mass achieved during young adulthood. During puberty, males typically accumulate more bone mass than females, resulting in a larger and stronger skeletal structure. This greater bone density acts as a buffer against bone loss later in life. Additionally, men have larger skeletons, which provides a biomechanical advantage, making their bones more resistant to fragility fractures. This foundational strength means men can lose more bone mass over time before their bones become as porous and fragile as those of a woman experiencing age-related bone loss.
Hormonal Differences: Gradual vs. Dramatic Decline
In women, the rapid and significant drop in estrogen levels during menopause is a primary driver of accelerated bone loss. Estrogen is a crucial hormone for maintaining bone density. Men do not experience a comparable hormonal event. Instead, testosterone levels decline more slowly throughout a man's life. While testosterone also helps build bone, much of its bone-protecting effect is due to its conversion into estrogen. This more gradual decline means bone loss in men occurs at a slower rate than in women until around age 65–70, at which point the rate of bone loss becomes similar. However, conditions that cause unnaturally low testosterone levels, such as hypogonadism, significantly increase a man's risk for osteoporosis.
Comparison of Bone Health Factors in Men vs. Women
| Feature | Men | Women |
|---|---|---|
| Peak Bone Mass | Typically higher, resulting in a stronger skeleton. | Typically lower, with smaller bone size. |
| Hormonal Changes | Gradual decline in testosterone and estrogen levels. | Rapid drop in estrogen during menopause, causing accelerated bone loss. |
| Rate of Bone Loss | Slower until around age 65–70, then similar to women. | Accelerates significantly during menopause, which starts earlier than age-related loss in men. |
| Risk of Fracture | Lifetime risk of fracture is lower, but mortality and disability post-fracture can be higher. | Higher lifetime risk of fracture, occurring earlier in life. |
| Secondary Causes | Up to 50–65% of cases are due to secondary causes like chronic disease or medication. | Postmenopausal hormone changes are a more common primary cause. |
Secondary Causes: The Primary Driver in Men
While postmenopausal changes are the most common cause of osteoporosis in women, in men, a secondary cause is identified in a majority of cases. This means the osteoporosis is a result of another medical condition, medication, or lifestyle factor rather than a natural part of aging. Common secondary causes in men include:
- Hypogonadism: Abnormally low testosterone levels.
- Chronic Diseases: Conditions affecting the kidneys, liver, lungs, or intestines.
- Medications: Long-term use of certain drugs, such as glucocorticoids (e.g., prednisone) or some treatments for prostate cancer that suppress testosterone.
- Lifestyle Factors: Excessive alcohol consumption, smoking, and a sedentary lifestyle.
Diagnosis and Prevention in Men
Because of the widespread misconception, osteoporosis in men is often underdiagnosed and undertreated. National screening guidelines for men are not as standardized as for women, leading to fewer men receiving bone density tests (DXA scans). However, men should be proactive and discuss bone health with their doctor, especially if they are over 60 or have known risk factors. Prevention and management strategies for men include:
- Adequate Nutrition: Ensuring sufficient intake of calcium and Vitamin D, which are critical for bone health. Sources include dairy products, leafy greens, fortified foods, and sunlight exposure.
- Regular Exercise: Weight-bearing and muscle-strengthening exercises, such as walking, jogging, hiking, and weightlifting, help build and maintain bone density.
- Lifestyle Adjustments: Limiting alcohol intake and quitting smoking are crucial for preserving bone mass.
- Fall Prevention: Taking steps to reduce the risk of falls, such as securing rugs and improving lighting, becomes increasingly important with age.

The Importance of Awareness
Ultimately, understanding the true nature of osteoporosis risk in men is vital. While the risk profile and timeline differ from women, the potential consequences of untreated bone loss are severe. Men face a higher mortality risk after a hip fracture than women, making awareness and early intervention even more critical. By educating themselves and their healthcare providers, men can take charge of their bone health and reduce their risk of devastating fractures.
Conclusion
While men have certain biological advantages that make osteoporosis less common, it is a serious condition that affects millions of men. The myth that men don't get osteoporosis is dangerous, as it leads to delayed diagnosis and treatment. By understanding the unique factors at play—including higher peak bone mass, slower hormonal changes, and a higher prevalence of secondary causes—men can take proactive steps to protect their bones. Prioritizing bone health through proper nutrition, exercise, and regular communication with healthcare providers is crucial for a healthy and active life in the later years.
