Male Hormone Restoration
Testosterone and Prostate Cancer: The Myth
For more than six decades, the medical establishment erroneously conjectured that testosterone replacement therapy increases one’s risk of developing prostate cancer. This fear has made it standard practice for physicians to deprive hypogonadal male patients of testosterone replacement that could otherwise provide them with a world of cardiovascular, musculoskeletal, cognitive, metabolic and other health benefits, as discussed earlier in the protocol.
Remarkably, though, it appears that, in most cases, the opposite is true—lower levels of endogenous testosterone present a greater risk of prostate cancer than higher levels.95 A review of data from the National Institutes of Health revealed that, in men of advancing age, “high testosterone levels are not associated with an increased risk of prostate cancer, nor are low testosterone levels protective against prostate cancer.”59
A collaborative review of 18 prospective studies compared serum concentrations of androgen and estrogen in 3,886 men with prostate cancer with those in 6,438 healthy controls. The results showed no significant associations between the risk of prostate cancer and sex hormone levels.60
In more than 500 men diagnosed with prostate cancer (followed over a mean of 8.7 years), high androgen levels were actually associated with a decreased risk of aggressive prostate disease, compared with no change in the risk of non-aggressive disease. Overall, levels of any steroid hormones (except estradiol) were not correlated with the risk of aggressive prostate cancer.96
Abraham Morgentaler, an associate clinical professor at the Harvard Medical School, in his book Testosterone for Life, convincingly makes the case for the benefits and safety of high testosterone versus the dangers of low testosterone. He also goes back to the original 1941 Nobel Prize-winning research97 about testosterone and shows how these data have been misinterpreted and unquestioned for over 70 years.
What You Need to Know: Optimizing Testosterone Levels in Aging Men
- Testosterone, the chief male hormone, is essential for libido and erectile function, and plays a crucial role in mood, energy, bone health, and body composition.
- Testosterone levels decline with age, usually beginning in a man’s mid-30s. Diminishing testosterone levels have been linked with disorders such as depression, fatigue, obesity and cognitive decline.
- Low testosterone in men is strongly associated with metabolic syndrome, and may be a risk factor for type 2 diabetes and cardiovascular disease.
- Restoring testosterone to youthful levels offers men a wealth of health benefits, including benefits for heart health, body composition, mood, and memory.
- Bioidentical testosterone has not been found to have adverse effects on the healthy prostate gland—in fact, it may help improve prostate symptoms in men with low-normal testosterone levels. Testosterone therapy is contraindicated in men with prostate cancer.
- Regular blood testing can help you and your physician decide if testosterone therapy is right for you. Optimizing testosterone levels requires a multi-pronged approach that includes optimal diet, proper nutrition, nutritional supplements, exercise, and bioidentical testosterone.
