Osteoporosis in Men: A Review of an Underestimated Bone Condition

A 2021 review published in the International Journal of Molecular Sciences laid out the scope of a problem that clinical practice has largely ignored: osteoporosis in men. An estimated 1 to 2 million American men have osteoporosis, and another 8 to 13 million have osteopenia. Yet the diagnosis and treatment rates are staggeringly low. Studies cited in the review found that up to 95% of men hospitalized for hip fractures are discharged without any osteoporosis workup or treatment. Men are also twice as likely as women to die within one year of a hip fracture, making the underdiagnosis not just a gap in care but a direct contributor to preventable mortality.

The review also highlighted that secondary causes of osteoporosis are more prevalent in men — found in roughly two-thirds of male cases compared to about one-fifth in women. Hypogonadism, glucocorticoid use, alcohol excess, and androgen deprivation therapy for prostate cancer are among the most common drivers. This means that male osteoporosis often has an identifiable, treatable underlying cause that goes undetected because nobody looks.

Why This Matters for Midlife Health

Osteoporosis is not a women's disease. It is a bone disease. The hormonal mechanisms differ — testosterone decline is more gradual than the estrogen cliff of menopause — but the endpoint is the same: weakened bones, fragility fractures, and life-altering consequences. Men in midlife, particularly those with risk factors like long-term corticosteroid use, low testosterone, or a family history of fractures, deserve the same proactive assessment that women receive. The current screening guidelines do not mandate it, which means men have to advocate for themselves.

The Tracking Connection

Kairos™ is built for both women and men navigating midlife hormonal changes. For men, that means tracking testosterone levels, symptoms of hormonal decline, medication history, and bone health metrics. When the system does not screen you by default, your own health record becomes the trigger. Bringing documented risk factors and symptom patterns to a provider visit is how men close the gap between what guidelines recommend and what actually happens in clinical practice.
