Testosterone’s Medical Uses
By Ross Macdonald
The Journal of the American Medical Association published a study measuring estradiol (the active form of estrogen) in men with chronic heart failure (CHF). The end results showed that men with the lowest level were 217 percent more likely to die, and men with the highest level were 133 percent more likely to die sooner from all sources than men with a balanced estradiol-testosterone level.
More than 16 years ago several research reports indicated that excess estrogen (in its active form of estradiol) contributed to artery blocking. Men with only slightly increased levels had twice the risk of a stroke and a higher chance of cardiovascular disease. The research also explained that men with “high” levels of estrogen and “low” levels of testosterone had higher incidences of benign prostate enlargement or hyperplasia (BPH). On the other hand, too-low estrogen levels can lead to osteoporosis and bone fractures.
A low testosterone level indicates an increased possibility of prostate cancer. This is detailed in research in Dr. Abraham Morgentaler’s book and from the National Institute of Health (NIH) in 2006. It is high levels of estrogen, not testosterone, that cause prostate cancer. Why?
First, the research done in 1940, which stated that testosterone was the culprit (for which the author received the Nobel Prize), was based on the results from dogs, a castrated man, and one normal man! Dr. Morgentaler’s research at Harvard has proved this research flawed.
Second, it was found that in aging men, obesity, especially belly fat, could cause estrogen levels to rise. This visceral fat produces an enzyme called aromatase, which converts testosterone into estrogen.
New research released from the 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.”
Harvard Medical School lists the optimum hormone levels as: DHEA 350-490ng/dl; estradiol 20-30pg/ml; total testosterone 550/700ng/dl; and free 0-25 pg/dl.
Abdominal exercises like sit-ups and crunches do NOT reduce belly fat. This fat is deep and wrapped around interior organs and is not affected by abdominal exercises. Exercises to reduce this visceral fat include cardio, push-ups, lunges, squats, and step-ups.
Now you can understand that belly fat is dangerous in more than one way.
Erectile dysfunction (ED) is closely related to vascular disease. ED is caused by a lack of blood flow to the penis that can occur gradually as one gets older. It is closely related to CVD, which may happen two or three years after the beginning of ED. The three known common medications (Viagra, et al) do not increase blood flow into the penis. Rather, they activate an enzyme called FDN3, which inhibits the blood from flowing out. Researchers from Harvard and 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 a daily dose of Cialis) have also been shown to reduce the urinary tract problems associated with BPH and reduce stress in the brain after a stroke by stimulating the growth of nerve cells. There are also remedies that inhibit aromatase from converting testosterone to estrogen.
