Conclusion
If
you are a male and you live long enough, you're going to have prostate problems.
It's a natural consequence of aging.
Men need to be aware that their prostate can cause them some significant symptoms.
Some 180,000 American men this year will be diagnosed with prostate cancer.
Celebrities afflicted by this disease include U.S. Senator Bob Dole, golf legend
Arnold Palmer, comedian Jerry Lewis, and race car driver great Richard Petty.
34,000 Americans will die from the disease. Prostate cancer is the leading non-skin
cancer in men. You have a higher chance of something going wrong with your
prostate than any other organ in your body, and yet people don't think about
that.
Prostate
101
Few men ever consider the walnut-sized gland located just below the bladder,
until it starts to give them trouble. In fact, a 1995 survey in the London Times
found that 89% of the men surveyed did not even know where the prostate was
located.
The prostate is a single, doughnut-shaped gland about the size of a walnut that
lies below the bladder and surrounds the urethra. It secretes a thin, milky
fluid that increases sperm motility and lubricates the urethra to prevent infection.
The fluid is extremely important for successful fertilization of the egg.
After the age of 50, the prostate begins to hypertrophy, or increase in size.
This condition is known as benign prostatic hypertrophy (BPH). The urethra
(the tube that carries urine from the bladder) runs through the middle of the
prostate. Consequently, when the prostate enlarges, the urethra is squeezed
and therefore compressed. This can pinch off the flow of urine, cause difficulty
in urinating, and make many men get up three or four times during the night
to urinate. Most men don't know enough about the symptoms. Many think
that it's just normal aging if you're getting up four to five times a night
to go to the bathroom. But it's just not the case. In reality, they are having
a prostate problem and they do not even know about it.
Other symptoms of BPH include hesitancy, dribbling, reduced force of the urinary
stream, and occasional bleeding or infection. This condition may even proceed
to the point of complete urinary obstruction, which is a surgical emergency.
5 to 10% of men at age thirty are already affected by this disease. 50% of
men between 40-60 years of age suffer from BPH, escalating to 90% of men by
age 85. If you live long enough, you are going to get it.
Fortunately, BPH is not deadly and can be
treated. Untreated BPH can lead to more serious complications such
as urinary tract infection and kidney damage. Severe cases of BPH may even require
surgery.
BPH is a medical diagnosis requiring professional expertise of a qualified
physician. Diagnosis is by digital rectal exam, where the prostate gland
feels boggy and may be two to three times larger than normal. Definitive diagnosis
of BPH can be made with ultrasound measurement. To differentiate between prostate
cancer and BPH, as the symptoms can be similar, a blood test called PSA (prostate-specific
antigen) is used. The PSA test is regarded as a highly significant and sensitive
marker for prostate cancer. The normal value for PSA is less than 4 ng/ml. A
level above 10 ng/ml is highly indicative of prostate cancer with a sensitivity
of over 90 percent.
Causes
of Prostatic Hypertrophy or Prostate Cancer
Conventional medical thinking holds that both prostatic hypertrophy and prostate
cancer are due to or are promoted by testosterone and/or dihydrotestosterone
(DHT). This increase in levels of testosterone and DHT is largely due to
a decreased rate of removal combined with an increase in the activity of the
enzyme 5-alpha-redcutase, which converts testosterone to DHT. Consequently,
standard medical therapy for these conditions includes blocking DHT formation
by drugs, avoiding testosterone replacement, or (in the case of prostate cancer)
orchiectomy (surgical removal of the testicles) to reduce testosterone output.
This hypothesis is not without its flaws. Some researches, such as Dr. William
Campbell Douglass, a pioneer in alternative medicine, supports the opposite
hypothesis that testosterone actually is protective against prostate cancer.
Another researcher, Dr. B. de Lignieres,
conducted a nearly two-year survey of men aged 55-70 years of age who were treated
with testosterone. He found that high levels of testosterone induced a number
of clinical benefits, while reducing prostate size and prostate-related symptomatology.
Dr. G. Debled, a European urologist, also believes that testosterone deficiency,
rather than excess DHT, is a major causative factor of BPH. In fact, Dr. Debled
uses testosterone to treat BPH. Furthermore, Dr Debled reports that in over
20 years of administering testosterone for patients with BPH, he has not had
a single case of prostate cancer develop - despite the fact that approximately
50 cases should have been discovered, based on statistical averages alone.
The final jury is still out on this
controversy. It is clear that the link between
testosterone and prostate cancer is not that firmly established, even among
the most mainstream of medical communities.
Therapeutic Options for
BPH

SurgicalUntil recently, a surgical procedure called TURP (trans-urethral resection of the prostate) was about the only solution for this troublesome condition. This procedure can be complicated and is uncomfortable. Fortunately, less invasive and more physiological approaches to prevent and treat BPH are now available. Surgical intervention is therefore reserved as a modality of last resort.
Drugs
Proscarâ is a prescription drug, which inhibits 5-alpha-reductase. Use of Proscarâ results in a 20% decrease in prostate size in 50% of the men who are treated, according to clinical studies. Proscarâ is fairly expensive and carries significant side effects of sexual dysfunction. Fortunately, there are botanicals that provide, without adverse effects, equivalent or greater benefits at reduced cost.
Botanicals
Plant-based medicines are much more popular prescriptions in Europe than synthetic drugs in treating BPH. Plant extracts account for more than 90 percent of all medications used in the medical management of BPH. In Italy, plant extracts account for roughly 50 percent of all medications prescribed for BPH, while alpha-blockers and 5-alpha-reductase-inhibitors account for only 5.1 percent and 4.8 percent, respectively.
The chances of clinical success with any of the botanical treatments of BPH appear to be directly related to the degree of obstruction as measured by the residual urine content. For levels below 50 ml, the results are usually excellent. For levels between 50 and 100 ml, the results are usually good. For residual levels between 100 and 150ml, it is difficult to produce results within the customary 6 to 8 weeks treatment period. If the level is above 150 ml, it is unlikely that botanicals can be of much help. Surgical intervention may be considered.
There are about 30 different plant-based compounds currently available, but only a few have been widely researched, clinically tested, and used extensively.
Saw Palmetto (Serenoa repens)
Extracts of the saw palmetto berry, a native of Florida, are being used extensively throughout the world for the relief of BPH. It works by inhibiting DHT binding to cellular receptors, inhibiting 5-alpha-reductase, and interfering with prostate estrogen receptors. As a result of these effects, excellent results have been produced in numerous clinical studies. Saw palmetto is commonly used worldwide for treatment of BPH. Both the French and German governments approve lipophilic extracts of saw palmetto berries for this purpose.
Recent studies show saw palmetto (Serenoa repens) berry extract can cause enlarged prostate glands to shrink and improve urinary flow. In one landmark study conducted by Braeckman and published in Current Therapeutic Research, 305 men were given a dosage of 160 mg of saw palmetto extract twice daily. After 45 days, 83% of the participants reported improvement. After 90 days, those showing improvement increased to 88%. Maximum urinary flow and the flow rate increased, while prostate volume actually decreased. Researchers also conducted "quality of life" tests in which participants were asked to evaluate their treatment and results. Most of the participants rated their lives after treatment as either "happy" or "satisfied." There were no serious adverse reactions from the treatments. A full 60% rated the treatment satisfactory to delighted, while only 10 percent felt unhappy about their results after 90 days of treatment. Maximum urinary flow (ml/s) increased from 9.8 to 12.2, mean urinary flow (ml/s) increased from 5.8 to 7.4, prostate volume decreased from 40,348 to 36,246 cubic ml, and the international prostate symptom score decreased from 19 to 12.4.
Saw palmetto's safety and efficacy is confirmed in another study conducted at the University of California Los Angeles School of Medicine. Researchers observed the effects of saw palmetto and placebos in 44 men between 45 and 80 years old who were diagnosed with BPH in a randomized, double-blind study. The study found that enlarged prostate tissue decreased from almost 18% to 11%. It was also noted that prostate glands shrunk by as much as 40% after treatment. Researchers concluded that saw palmetto appeared to be a safe and highly desirable option for men with moderate BPH. Of special note is that after the study was no longer blinded, 41 of the 44 men elected to continue saw palmetto therapy.
Positive results with saw palmetto have been confirmed in numerous open, as well as double-blind, placebo-controlled clinical trials in the past few decades. All of these studies demonstrated statistically significant and dramatic improvements in the symptoms of BPH, which included increased volume and rate of urine flow, alleviation of pain and night time urinations, and reduced number of voidings per day. Overall, these studies all showed a consistent benefit of saw palmetto extract, with virtually no side effects of any severe consequence. Most subjects experienced relief within days of beginning the therapy, with benefits continuing to improve over time to as much as one year. Most studies however, were terminated after 30, 60 or 90 days while the majority of the subjects elected to continue on the botanicals
When it comes to saw palmetto, health professionals universally appear to agree that the herb is safe and effective, and there is little disagreement within the medical establishment.
A recent study compared Proscarâ
(a drug used to treat BPH) with saw palmetto extract. Saw palmetto extract showed
reduced side effects, an equivalent or greater benefit, and reduced cost of
treatment. While Proscarâ typically takes up to a year to produce significant
benefits, saw palmetto extracts produces better results in a much shorter period
of time. The optimum dose of saw palmetto
in most clinical studies was 320 mg per day.
Physicians routinely use blood prostate-specific antigen (PSA) levels to test
for prostate cancer. While saw palmetto has no effect on PSA levels, Proscarâ
actually lowers them, which may interfere with test results and cloud the PSA
test results.
Pygeum africanum
Pygeum is an evergreen tree native to Africa. Its bark has historically been
used in the treatment of urinary tract disorders. Virtually all of the research
on pygeum has featured a pygeum extract standardized to contain 14 percent triterpenes,
including beta-sitosterol and 0.5% n-docosanol.
Extracts of the African herb Pygeum africanum
have also shown impressive results in relieving symptoms of BPH. In
one clinical trial, 18 patients with BPH or chronic prostatitis were studied.
Many of these also had sexual disturbances. They all received an extract of
pygeum for 60 days. At the end of the program, all urinary parameters that were
investigated were improved, and sexual disturbances were relieved. In a placebo-controlled
French trial of 120 patients, the pygeum group experienced significant reductions
in the number of urinations and more complete bladder emptying with less residual
volume than the control group.
An international, multi-center, double-blind, controlled trial of pygeum extract
in 263 patients with BPH over a 60 day period showed improved urinary symptoms
in over 60 percent of the patients. Most of the clinical studies with pygeum
used dosages ranging from 75-150 mg per day, although much less can be used
when taken in combination with other botanicals such as saw palmetto.
In double blind-studies comparing pygeum and saw palmetto, the saw palmetto extract produced greater reduction of symptoms and was better tolerated. The two extracts have somewhat overlapping mechanisms of actions, as some of the effects on prostate secretion are not produced by saw palmetto but with pygeum. The two are often used in combination, with synergistic effect.
Stinging Nettle (Urtica dioica)
Extracts of stinging nettle are used routinely
in Europe to treat BPH. It appears to interact with binding DHT to
cytosolic and nuclear receptors. Stinging nettle shares several mechanisms with
pygeum and saw palmetto, but has several actions that are unique. Fewer studies
have been conducted using this botanical alone, and the results comparing stinging
nettle with saw palmetto showed that saw palmetto
is a more effective agent in alleviating symptoms of BPH.
However, stinging nettle has been tested
and found to be effective in BPH as a single nutrient, or in combination with
pygeum and saw palmetto. Extracts of stinging nettle when used
alone were superior to the placebo, but efficacy was enhanced when combined
with pygeum. The dosages of stinging nettle in the clinical studies were 300
mg per day. Much less can be used in combination with other botanicals.

Diet
Diet appears to play a role in the health of the prostate gland from clinical experience. It is important to avoid pesticides, increase intake of zinc, essential fatty acids and keep cholesterol level below 200 mg/dl. Zinc has been shown to inhibit the activity of 5-alpha-reductase, the enzyme that irreversibly converts testosterone to DHT. The administration of essential fatty acids (EFA) has been shown to significantly improve symptoms of many BPH patients. These effects appear to be due to the correction of an underlying EFA deficiency, since patients with BPH often have associated seminal lipid levels that are often abnormal. Cholesterol damaged by free radicals is particularly toxic and carcinogenic to the prostate. Drugs that lower cholesterol levels have been shown to have a favorable influence on BPH.
Since there have been no clinical trails on the use of diet alone in the treatment of BPH, the following diet recommendations are based mostly on clinical experience. The diet should be high in protein, low in carbohydrate, low in animal fats, and high in essential fatty acids. Focus on whole, unprocessed foods (legumes, vegetables, fruits, nuts, and seeds).
Conclusion
Benign
Prostatic Hyperplasia (BPH) is a near universal disease of aging men.
Furthermore, all men over 40 should have an annual digital rectal exam on
their prostate, and men over 50 also need to have a special blood test to
screen for prostate cancer. Prevention and enhancement of prostatic health
with botanicals is widely practiced in Europe and has been shown to be more
effective than drugs.Decades of studies and hundreds of clinical studies have shown that extracts from Saw palmetto, Pygeum africanum, and Stinging nettle have all demonstrated efficacy when used in the treatment and prevention of benign prostatic hypertrophy (BPH). Because of their multiplicity of actions, it should be no surprise that when these botanicals are combined, they are even more effective than when used individually. In summary, roughly 90 percent of men who have mild to moderate BPH experience some improvement in symptoms during the first four to six weeks of therapy.
In particular, saw palmetto has been shown to have very few, if any, side effects. Since it does not interfere with measuring of PSA levels, saw palmetto won't mask cancer during PSA tests. For those who like to alleviate symptoms of BPH, botanicals should be seriously consider as a first line natural alternative to drugs. For those who are keen to prevent the onset of BPH, these botanicals acts as a prophylactic and can be considered for all healthy men over 35 years old as part of a comprehensive anti-aging program.
