Testosterone May Protect Against Hardening Of The Arteries

Testosterone supplementation has received a fair share of “bad press.” Mostly due to health problems (sterility, coronary artery disease, liver damage, and brain tumors), caused in young men and women who should not be taking testosterone supplementation, but do so at super-physiological doses, to enhance athletic performance.

Many physicians also think, based on some medical studies, that the supplementation of testosterone “encourages” atherosclerosis (Hardening of the arteries)

Now, new research says the opposite maybe true, Testosterone may protect you from atherosclerosis.

Publishing in the May 17, 2005 issue of the American College of Cardiology, researchers found that men with low testosterone levels had more arterial thickening in the carotid artery in the neck than men with “normal” testosterone levels.

In my opinion I have found little evidence to support that testosterone supplementation to restore levels lost to aging can cause health problems. Numerous research supports the opposite. Study participants and researchers noted gained muscle, a slowdown in bone loss, increased sexual desire, and better cognitive skills.

Certain Exemptions – When not to take Testosterone supplementation?
Men taking testosterone supplementation should have PSA tests performed twice a year and have an annual manual examination of their prostate gland. No evidence suggests that testosterone supplementation causes prostate cancer. In fact, studies show a higher incidence of prostate cancer in men with a lower baseline level of testosterone. Studies suggest that in the presence of existing prostate cancer, testosterone supplementation may accelerate tumor growth.

Testosterone and Ischemic Heart Disease

Researchers writing in Cardiovascular & Hematological Disorders Drug Targets examined lower testosterone levels in patients with ischemic heart disease. The researchers noted recent studies showing that testosterone level is lower in patients with ischemic heart diseases, and testosterone treatment alleviates the symptoms and there is increasing evidence to suggest testosterone confers cardioprotection by direct action on the myocardium.

Testosterone and Cognitive Function

A study in the European Journal of Endocrinology says “Low endogenous levels of testosterone may be related to reduced cognitive ability, and testosterone substitution may improve some aspects of cognitive ability.”

Beauchet O. Testosterone and cognitive function: current clinical evidence of a relationship. Beauchet O. Eur J Endocrinol. 2006 Dec;155(6):773-81.

BACKGROUND: Testosterone levels decline as men age, as does cognitive function. Whether there is more than a temporal relationship between testosterone and cognitive function is unclear. Chemical castration studies in men with prostate cancer suggest that low serum testosterone may be associated with cognitive dysfunction. Low testosterone levels have also been observed in patients with Alzheimer’s disease (AD) and mild cognitive impairment (MCI). This paper reviews the current clinical evidence of the relationship between serum testosterone levels and cognitive function in older men.

METHODS: A systematic literature search was conducted using PubMed and EMBASE to identify clinical studies and relevant reviews that evaluated cognitive function and endogenous testosterone levels or the effects of testosterone substitution in older men.

RESULTS: Low levels of endogenous testosterone in healthy older men may be associated with poor performance on at least some cognitive tests. The results of randomized, placebo-controlled studies have been mixed, but generally indicate that testosterone substitution may have moderate positive effects on selective cognitive domains (e.g. spatial ability) in older men with and without hypogonadism. Similar results have been found in studies in patients with existing AD or MCI.

CONCLUSIONS: Low endogenous levels of testosterone may be related to reduced cognitive ability, and testosterone substitution may improve some aspects of cognitive ability. Measurement of serum testosterone should be considered in older men with cognitive dysfunction. For men with both cognitive impairment and low testosterone, testosterone substitution may be considered. Large, long-term studies evaluating the effects of testosterone substitution on cognitive function in older men are warranted.

Link Between Testosterone and Prostate Cancer

Testosterone Replacement Therapy and the Risk of Prostate Cancer. Is there a link?

Writing in the Canadian Journal of Urology, Researcher Abraham Morgentaler of the Division of Urology, Harvard Medical School, Beth Israel Deaconess Medical Center, Boston, Massachusetts, says that “there is an absence of scientific data supporting the concept that higher testosterone levels are associated with an increased risk of prostate cancer.”

Specifically, no increased risk of prostate cancer was noted in 1) clinical trials of testosterone supplementation, 2) longitudinal population-based studies, or 3) in a high-risk population of hypogonadal men receiving testosterone treatment. Moreover, hypogonadal men have a substantial rate of biopsy-detectable prostate cancer, suggesting that low testosterone has no protective effect against development of prostate cancer.

These results argue against an increased risk of prostate cancer with testosterone replacement therapy.

From our December 6, 2005 Newsletter
An article by Susan Brink of the Los Angeles Times recently appeared in newspapers around the country discussing the link between testosterone and prostate cancer.

The article says “The belief that testosterone increases the risk of prostate cancer is so widely accepted that study after study that tries to show it and can’t keeps getting repeated over and over,” says Dr. Abraham Morgentaler, a Boston urologist and author of the 2004 review. “People don’t believe it.”

Here is a press release from the Harvard Medical School.

“Boston–January 2004, Harvard Medical School affiliate Beth Israel Deaconess Medical Center–A retrospective analysis by researchers at Beth Israel Deaconess Medical Center published in The New England Journal of Medicine found no causal relationship between testosterone replacement and prostate cancer or heart disease risk. The comprehensive review of 72 studies, addresses the current controversy about testosterone replacement therapy and its potential health risks to men.”

Testosterone For Men

TESTOSTERONE FOR MEN
The medicinal value of testicles have been documented in the Bible, the writings of the ancient Egyptians and from India. Indeed, nearly every ancient culture believed that the testicles held some form of masculine power.

The use of testosterone as a means of restoring vitality can be traced in the modern era to the work of famed medical researcher Charles Edouard Brown-Séquard (1817-1894). Brown-Séquard had been hailed as a medial pioneer for his ability to treat difficult and previously untreatable disorders of the nervous system. At the age of 72, when he noticed his declining vitality, he injected himself with the extracts of crushed testicles from dogs and guinea pigs and increased his physical strength and intellectual abilities and announced his results to his colleagues.

Brown-Séquard’s work sparked an influx of research and medical use of testicles, however, technology could not, at that time, substantiate his claims.

In 1935 Dutch researchers were able to isolate and create a synthetic form of testosterone. Doctors prescribed it in males with hypogonadism—where levels of testosterone are so low it prevents normal sexual development. Older men suffering from impotence were also treated. A few years later, testosterone supplementation for these disorders became “mainstream.”

What are the potential signs of Testosterone deficiency in men?

1. Diminished Libido
2. Erectile Dysfunction
3. Fatigue
4. Muscle Weakness
5. Bone Density Loss, with increased fracture risk
6. Decrease in Endurance, Stamina
7. Loss of Body Hair
8. Depression
9. Mood Disorders
10. Obesity or increase in fat mass
11. Hypertension
Testosterone Supplementation
Testosterone supplementation has received a fair share of “bad press.” Mostly due to health problems (sterility, coronary artery disease, liver damage, and brain tumors), caused in young men and women who should not be taking testosterone supplementation, but do so at super-physiological doses, to enhance athletic performance. Indeed, testosterone is part of the “Steroid Crisis” affecting amateur and professional sports.

There is very little evidence to support that testosterone supplementation to restore levels lost to aging can cause health problems. Numerous research supports the opposite. Study participants and researchers noted gained muscle, a slowdown in bone loss, increased sexual desire, and better cognitive skills.

Drops in testosterone levels begin in men after the age of 30 and its effects are described as “male menopause” or andropause when problematic.

The recognition that men can suffer from sex hormone deficiency just as women do, and be treated for this deficiency in the same manner as women prescribed hormonal supplementation have lead to an explosion in the demand for testosterone supplementation.

Testosterone Supplementation Risks
It is important to understand that not all men will benefit from Testosterone supplementation. The goals, realities, and risks of Testosterone supplementation should be discussed, at length, with your physician prior to onset of treatment.

Testosterone Supplementation and Prostate Cancer
Men taking testosterone supplementation should have twice yearly PSA tests and once yearly manual examination of their prostate gland. No evidence suggests that testosterone supplementation causes prostate cancer. In fact, studies show a higher incidence of prostate cancer in men with a lower baseline level of testosterone. Have you ever heard of a teen age male (with the highest testosterone levels) having prostate cancer? Studies do suggest that in the presence of existing prostate cancer, testosterone supplementation may accelerate tumor growth. It also appears that there is an association of high estrogen levels and prostate cancer.

Warnings:
Any hormone supplementation can adversely effect other hormone levels.

Testosterone supplementation must be monitored by a physician through blood testing. Very high levels of testosterone can lead to severe and dangerous health problems.

Men who take too much Testosterone may can shut down production of DHEA and other sex hormones.

The result is the frequently seen side effects of:
1. Testicular shrinkage
2. Impotence
3. The development through increased estrogen production of breasts (gynecomastia).
4. Male Pattern Baldness
5. Infertility

Other complications may include:
1. Fluid retention (swelling)
2. Heart Problems through increasing hardening of the arteries.
3. Increase in body hair
4. Acne
5. Liver problems
6. Kidney disease
7. High Blood Pressure
8. Gallstones
