So many times you would leave the urologist’s office, after having the results of a PSA test explained, filled with much uncertainty as to whether the indicators could be incorrect. Knowing that PSA screening is not a precise diagnostic instrument for determining cancer of the prostate, can lead to anxiety and depression. But those days are almost over. New research study found PSA screening is more reliable in men taking the PSA level reduction drug dutasteride.
Dutasteride is a dual 5-alpha-reductase inhibitor, approved by the FDA for the treatment of symptomatic benign prostatic hyperplasia (BPH), better known as enlarged prostate.
A hormone, dihydrotestosterone (DHT), causes the prostate to slowly grow over time. Dutasteride slows down the production of DHT over time, leading to shrinkage of the enlarged prostate, and reducing the symptoms of BPH.
Dutasteride reduces the risk of prostate cancers by keeping the turmors small enough to avoid detection by a biopsy. Thus, men taking Dutasteride who still show a subsequent rise in PSA levels should be associated with having aggressive high-grade cancer.
This new study reveals how Dutasteride enhances the ability of rising PSA levels to detect high-grade cancers that require early diagnosis and treatment, while decreasing the detection of tumors that are harmless. However, it doesn’t mean men should take dutasteride to better PSA scores.

The good news you just received about the result of a second prostate biopsy test could be misleading. Pathologists estimates show 20 percent of all prostate biopsies are false negative… meaning they can miss cancer.
A negative biopsy doesn’t mean you don’t have cancer. Your chances of having cancer increases, if your biopsy only included samples from part of your prostate. In fact the cancer could be quite extensive. The greater the number of samples biopsied, the better your chances of being misdiagnosed.
Perhaps there was no need to do the test at that time. Because, according to Dr. James A. Eastham at Memorial Sloan-Kettering Center, no one should be referred for a biopsy based on one single PSA test that is slightly elevated. Did you have a second prostate-specific antigen (PSA) before the second prostate biopsy was performed?
You should be here at this threshold because your second prostate-specific antigen (PSA), and digital rectal exam (DRE) continued to be abnormal. Experts recommend repeating the test 4 to 6 weeks before doing second biopsy. False positives are common, because cancer is not the only cause for increased PSA levels. A recent episode with constipation, inflammation, or recent ejaculation can raise your PSA score. But fluctuations should never be taken lightly.
Researchers at Oregon Health & Science University Cancer Institute and Portland Veterans Medical Center have discovered a way to identify which men need second prostate biopsy, even though they were given a clean bill of health after the first biopsy. The single most definite indicator given for a repeat biopsy was a high PSA, Gleason score 7 or higher, adjusted for prostate size.
Prostate cancer is the second most deadliest cancer in men. An estimated 300,000 are diagnosed annually, and 30,000 men will die of the disease, according to the American Cancer Society. You could be one of them.

There is enough data available to support once-a-day use of tadalafil in men with erectile dysfunction, and signs and symptoms of BPH. This is the finding, reported by UroToday, of a recent study on the effects of tadalafil on benign prostatitic hyperplasia.
The study included sexually active men with ED, who also suffered BPH and lower urinary tract symptoms, such as intermittency, urgency, incomplete emptying, weak urinary stream, urinary frequency, straining and nocturia.
The result of the study showed significant improvements from baseline with once-daily tadalafil in all stratifications. Hereby suggesting that once-daily tadalafil may be effective in treating a diversified group of men suffering from BPH and other lower urinary tract symptoms.

Long term study shows Dutasteride reduced the risk of prostate cancer detected via prostate biopsy by 23% over a period of four years. The study group included men between the age of 50 to 75 who had increased cancer risk, with prostate specific antigen (PSA) levels between 2.5 and 10 ng/ml.
Dutasteride is a 5-alpha-reductase enzyme inhibitor that inhibits both type 1 and type 2 isoenzymes. These enzymes convert testosterone into dihydrotestosterone (DHT) in the prostate gland. High levels of dihydrotestosterone accumulates and cause hyperplasia. Dutasteride capsules have been approved by the FDA for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate gland.
BPH is benign enlargement of the prostate gland in men over forty, which may not present any problems until over sixty. BPH causes urinary track symptoms such as frequent urination, leaking, and urinary urgency. Dutasteride trials show significant improvement of urinary track symptoms.

Thirty percent of patients who are diagnosed with prostate cancer choose the wait-and-see option, also called ‘active surveillance’, which is unique only to prostate cancer, and cannot be applied to other type of cancers, since prostate cancer is a very slow growing neoplasm. Those men who chose this option, must still have regular PSA testing and physical testing every 6 month, plus a second biopsy after a year. In doing so men may avoid impotence, incontinence and other side effects. The no treatment option is only possible because doctors have the data to support it. It doesn’t mean no treatment ever, but rather no treatment right now.

We know that aging has a negative effect on sperm volume. So, more than ever before, you need to consume a diet rich in nutrients that will maintain an adequate and healthy volume of sperm.
A high intake of antioxidants will not only increase sperm count, but also affect its quality and mobility. Fish oils play an important roll in maintaining sperm volume. While arginine and l-carnitine decrease oxidation, thus contributing to quality semen production.
The common causes of structural damage to sperms are infrequent ejaculation, varicocele, drugs and heat. Research reveals greater DNA damage to diabetic men, than those not touch by the disease.
Semen consists of fluids that protect the sperm cells… seminal fluid 60%, prostate fluid 30%, Cowper gland fluid 5%, and testicle fluid 5%. These fluids must be in perfect balance in order to protect the sperm cells. Consuming more fish, or taking fish oil supplements can increase fluids to provide that protection.

Researchers at Duke School of Nursing discovered that flaxseed supplement actually slows prostate tumor growth. Flaxseed is rich in Omega-3 fatty acids, and fibers known as lagnans. Flaxseed is edible, but has to be grounded since the seed has an indigestible coat. Sprinkle it on food or mix with beverage for best result.
Researchers found that men in the flaxseed group had the slowest prostate tumor growth rates compared to the other groups. “The seed,” said Dr. Wendy Demark-Wahnefried, the lead investigator for the study, “may be able to interrupt the chain of events that leads cells to divide irregularly and become cancerous. Another reason could be that the Omega-3 fatty acids prevents cancer cells from sticking to body cells.”
The study was funded by the National Institute of Health, and researchers from the University of Michigan, and North Carolina University at Chapel Hill participated
