Men die younger than women in virtually every studied population — by an average of 5-7 years in developed countries. This longevity gap is driven by a combination of biological factors, behavioral patterns, and healthcare engagement differences that are each addressable. Understanding the male-specific aging trajectory — testosterone decline, cardiovascular risk acceleration, and the healthcare avoidance pattern that allows preventable disease to go undetected — is the first step toward closing it.
The male longevity disadvantage — men dying an average of 5 to 7 years earlier than women in developed countries — is one of the most consistent and underappreciated public health findings in medicine. It is so consistent across populations that it has been normalized as inevitable. It is not. The biological component of the male longevity gap (X chromosome gene dosage effects on immune regulation, testosterone-driven cardiovascular risk) is real but modest. The behavioral and healthcare engagement component — men's significantly lower rates of preventive care, symptom reporting, and treatment adherence — is larger and substantially more addressable.1
Men experience myocardial infarction, stroke, and sudden cardiac death approximately 10 years earlier than women. The mechanisms are multiple: testosterone promotes LDL-C and ApoB elevation and reduces HDL-C; estrogen (the female cardiovascular protective hormone) is absent in men; men are more likely to smoke and engage in high-risk behaviors; and men are less likely to receive preventive cardiovascular care. The consequence is that many men in their 40s and 50s are carrying significant atherosclerotic burden that has never been measured and will manifest as cardiovascular events in their 60s. CAC scoring in men over 40 with any cardiovascular risk factors is a high-priority, low-cost investment in longevity management.2
Aggressive early cardiovascular risk factor optimization — ApoB below 70 mg/dL, blood pressure below 120/80, insulin sensitivity (fasting insulin below 7 uIU/mL), smoking cessation, and physical fitness — in men's 30s and 40s addresses the atherosclerotic disease that is seeding itself during precisely these decades. Most of the cardiovascular events that kill men in their 60s began accumulating plaque in their 40s when they felt entirely healthy.
Testosterone production from Leydig cells in the testes declines at approximately 1 to 2 percent per year after age 30. This gradual decline produces what is sometimes called andropause or late-onset hypogonadism — a syndrome of symptoms that includes reduced energy and vitality, increased visceral fat accumulation, loss of lean muscle mass, reduced libido, erectile dysfunction, mood changes (including depression and irritability), and cognitive changes including reduced verbal memory and processing speed. Because these changes are gradual and individually subtle, many men attribute them to "just getting older" rather than recognizing them as symptoms of a hormone deficiency state that may be clinically addressable.3
Evaluation: total testosterone, free testosterone (calculated or equilibrium dialysis), LH, and FSH. Morning fasting samples are required due to testosterone's diurnal variation (peak in early morning). Hypogonadism is defined by consistently low testosterone (below 300 ng/dL total testosterone) combined with clinical symptoms. As covered in article 7.1, the TRAVERSE trial has established cardiovascular safety of TRT in appropriate candidates, removing the primary barrier to treatment for men with confirmed hypogonadism.
Prostate cancer is the most common non-skin cancer in men and the second leading cause of cancer death. The challenge in prostate cancer management is its extraordinary heterogeneity: indolent prostate cancers (Gleason 6) virtually never cause death and are frequently over-treated; aggressive prostate cancers (Gleason 8-10) kill rapidly if not identified early. The distinction — which requires biopsy with Gleason grading — has made population-level PSA screening controversial (identifying predominantly indolent cancers that will be over-treated). The longevity medicine approach: baseline PSA at age 40-45, PSA velocity tracking (rate of rise over time), PSA density (PSA adjusted for prostate volume to reduce false positives), and MRI-targeted biopsy when indicated. This approach attempts to preserve detection sensitivity for aggressive cancers while reducing unnecessary biopsies of indolent disease.4
Addressing the behavioral component of the male longevity gap — the reluctance to seek medical care, the tendency to minimize symptoms, and the lower rates of preventive care adherence — is genuinely difficult because it requires changes in deeply held attitudes about health and self-sufficiency. Several practical strategies: establishing care with a primary care physician before health problems develop (not in response to crisis); scheduling annual comprehensive bloodwork proactively; making preventive screenings (CAC score, colonoscopy, DEXA) part of a routine health maintenance protocol; and involving partners and family members who are often more proactive about health in supporting engagement with preventive care.5
