Testosterone: Cancer, Heart, ED

Extending Lives

By Ross Macdonald

Research published in 1940 (for which the author received the Nobel Prize) stating that testosterone was the cause of prostate cancer was later proven by Dr. Abraham Morgentaler to be flawed. The flawed research was based on test results from dogs, a castrated man and one normal man!

A low testosterone level indicates an increase in the possibility of prostate cancer. This is detailed in research from Harvard Medical School in Dr. Abraham Morgentaler’s book and from the National Institutes of Health (NIH) 2006. It is high levels of estrogen, not testosterone, that causes prostate cancer.

Research also found that in aging men, obesity, especially belly fat, can cause estrogen levels to rise. This visceral fat produces an enzyme called aromatase, which converts testosterone into estrogen. New research just released from the University of Texas Health Science Center states, “For the first time we have demonstrated that excess fat (adipose belly fat) is a key factor in cancer progression regardless of the diet contributing to the excess weight.”

Some men with excess belly fat can have more estrogen than post-menstrual women. Besides excess estrogen being one of the leading factors in prostate cancer, it also is a factor in women’s breast cancer. The research also explained that men with “high” levels of estrogen and “low” levels of testosterone had higher incidents of benign prostate enlargement (BPH).

Over 16 years ago several research reports indicated that excess estrogen (in its active form of estradiol) and low levels of testosterone contributed to atherosclerosis (artery blocking). Men with only slightly increased levels had twice the risk of a stroke and a higher risk for cardio vascular disease (CVD). Testosterone is necessary to enable HDL (good cholesterol) to remove build-up cholesterol from the arterial walls and return it to the liver for disposal. A combination of low HDL and low levels of testosterone is a path to serious CVD. Harvard Medical School lists the optimum hormone levels as: DHEA -350-490ng/dl; Estradiol 20-30pg/ml; total testosterone 550/700ng/dl; and free testosterone 20-25 pg/dl. Major studies also definitively show that a combination of low levels of free testosterone coupled with low levels of vitamin D3 increase the risk of CVD by over 233 percent.

Abdominal exercises like sit-ups and crunches do not reduce belly fat. This fat is deep and wrapped around your interior organs and is not affected by abdominal exercise. Exercises to reduce this visceral fat include cardio, pushups, lunges, squats, and step-ups. Now you will understand that belly fat is dangerous in more than one way.

Erectile Dysfunction (ED) is caused by a lack of blood flow, which can occur gradually as one gets older. It is closely related to CVD, which may happen two or three years after the beginning of the ED. The three known common medications (Viagra et al.) do not increase blood flow into the penis (however, there are supplements that do, so don’t worry). They activate an enzyme called FDN3 which inhibits the blood from flowing out. Researchers from Harvard and the Life Extension Foundation have written several articles and books about ED, its probable causes and remedies. There are several non-prescription supplements that have a proven beneficial record of alleviating ED.

Viagra et al (especially the daily dose of Cialis) have also been shown to reduce the urinary tract problems associated with BPH (benign prostate hyperplasia) and reduce stress in the brain after a stroke by stimulating the growth of nerve cells.
