Beyond cardio, resistance training is critical for sexual function. Data shows men who actively maintain muscle mass as they age are three times less likely to suffer from erectile dysfunction, low desire, and dissatisfaction with sex.

Physicians rarely ask about sexual health not due to personal discomfort, but because major Electronic Health Record (EHR) systems like Epic lack specific, billable fields for it. This systemic flaw means doctors are not incentivized to gather this critical data on cardiovascular and mental health.

Contrary to the popular focus on Kegels, an overly tight pelvic floor—often from stress or injury—can cause erectile dysfunction, painful sex, and premature ejaculation. For these individuals, relaxation exercises are more beneficial than strengthening, which can worsen symptoms.

Nocturnal erections serve as a comprehensive indicator of a man's cardiovascular, metabolic, hormonal, and sleep health. Unlike metrics like muscle mass, this biological function cannot be faked or directly trained at the gym; it's an honest signal of the body's underlying condition.

A study on sex frequency and longevity found a startling correlation: individuals having sex once a week live 49% longer than those having sex only once a year. This suggests that sexual activity is a strong indicator of overall health, cardiovascular fitness, and social connection.

Dr. Mohith Kara equates Viagra to the narcotic Vicodin because both treat a symptom while masking the underlying, potentially life-threatening cause. Using a pill for ED can delay the diagnosis of cardiovascular disease, diabetes, or metabolic problems for years, with dangerous consequences.

Neuroscientist Andrew Huberman explains that Tadalafil, originally a prostate health drug, improves blood perfusion at low doses (2.5-5mg). A Stanford urologist suggests most men over 40 could benefit from this daily regimen, framing it as a health measure rather than just for erectile dysfunction.

The vast majority of men who believe they have ED are actually experiencing a normal aging process where blood leaves the penis faster (venous leak). True ED, the inability to get an erection, is rare and signals a serious arterial problem. This over-medicalization creates unnecessary shame.

Data shows that engaging in 150 minutes of moderate-intensity cardiovascular exercise per week yields improvements in erectile function scores equivalent to those from medications like Viagra. This highlights the power of lifestyle changes over pharmaceutical intervention for sexual health.
