A study of 23,802 Swedish men found that getting an MRI before scheduling a prostate biopsy was associated with reduced proportion of men who received biopsies,, reduced biopsies in low-risk prostate cancers (Gleason score of 6 or lower) who usually are not treated, and increased detection of the number of men at high risk for prostate cancer (Gleason score greater than 6) who need immediate treatment
Prostate cancer usually grows slowly over many years, so a study was designed to find out if it is safe to delay treatment for many years. More than 1,600 men diagnosed with localized prostate cancer (that had not spread beyond the prostate) were randomly assigned to receive surgery, radiation or waiting with active monitoring. Fifteen years later, there was no statistical difference in deaths from prostate cancer between the three groups: 3.1 percent in the active-waiting group, 2.2 percent in the surgery group, and 2.9 percent in the radiation group.
Many men take testosterone because they think it will help them to function better sexually, increase muscle strength, raise bone density, and improve mood, behavior, and mental function. As of May 2022, the only FDA-approved indication for men to take testosterone is having low testosterone levels. Testosterone has not been approved for age-related drops in testosterone, and there is significant concern that testosterone use is associated with increased plaques in the arteries leading to the heart.
Extensive data show that the typical western diet, obesity, and lack of exercise are associated with increased risk for prostate cancer. Recent studies now show that intense exercise and an anti-inflammatory diet help to reduce markers for prostate cancer progression in men who already have prostate cancer.
Impotence often precedes a heart attack by three to five years. A review of the scientific literature found that men who are impotent have a 59 percent increased risk for heart attacks, a 34 percent increased risk for a stroke, and a 33 percent increased risk for dying from any cause. One study showed that impotent men were twice as likely to develop heart disease.
A study of 90,494 U.S. veterans with prostate cancer found that more than half suffered from uncontrolled risk factors for heart attacks. Men who suffer from prostate cancer have a very high rate of heart attack risk factors and heart disease.
A study of 21,469 U.S. male health professionals, ages 40 to 75, found that those who followed a Mediterranean diet had a markedly reduced rate of erectile dysfunction. The more closely they followed the dietary rules, the more likely they were to be able to achieve an erection.
A study of 39,622 men who had blood clots in their veins shows that those who took testosterone (for legitimate medical reasons or not) suffered increased risk for forming potentially-fatal blood clots.
A study of more than 3,400 former National Football League players, average age 52, found that those who had had a concussion were at increased risk for low testosterone and erectile dysfunction, regardless how young or old they were.
A review of published studies shows that the world-wide incidence of inability to achieve an erection varies widely from three percent to 76.5 percent, and the geographical incidence of impotence is associated with all the same risk factors as those for heart attacks, dementia and having an enlarged prostate (BJU International, July 3, 2019)....
Almost all North American men will develop prostate cancer if they live long enough. However, fewer than five percent of men diagnosed with prostate cancer will die from that disease and the 15-year survival rate is 96 percent.
The same lifestyle factors and diseases that cause impotence also cause heart attacks. Many impotent men have no idea they are at high risk for a heart attack and cannot even name any of the six factors that put them at high risk for both impotence and heart attacks: smoking, overweight, diabetes, high cholesterol, high blood pressure and lack of exercise.
Several studies show that a high-plant diet such as a Mediterranean diet is associated with reduced risk for the type of prostate cancer than can kill you, and if you already have prostate cancer, that diet is associated with reduced chance of dying from that disease.
One in three North American adults have to get up to urinate more than twice a night, and a study presented at the European Society of Urology shows that the most common cause may be taking in too much salt.
Medical journals have reported trials that examine the benefits and harms of taking testosterone for men over 65 with low blood levels of testosterone (less than 275 ng/dL). At 12 study sites across the country, a total of 790 participants were given testosterone gel or a placebo applied daily to the skin.
It looks more and more as if prostate cancer is a metabolic disease that is influenced by your lifestyle. Extensive research has failed to show association between infections and prostate cancer risk, but following a healthful diet and lifestyle has been associated with reduced risk for the aggressive type of prostate cancer that can spread and kill.
A new study followed more than 1500 men with prostate cancer for ten years (New England Journal of Medicine, September 14, 2016). This is the first study to compare treatment with surgery or radiation to no treatment at all ("watchful waiting").
High blood sugar levels, particularly fructose, turn on a man's immunity that is supposed to attack and kill invading germs. Instead his immunity attacks his own normal cells to damage the genetic DNA material and turn normal prostate cells into cancer cells.
We have no data to show that testosterone helps to prevent heart attacks in older men. In an effort to find out if taking testosterone could help to prevent heart attacks, doctors gave injections of testosterone to 45 men and placebo to 43 men for 40 weeks. Those treated with testosterone showed a reduction in the cardiac biomarker NT-proBNP, but no reduction in another biomarker, hs-cTnT.
Heart attacks are the main cause of death in men diagnosed with prostate cancer. More than 230,000 American men are newly diagnosed with prostate cancer each year. Because prostate cancer usually progresses so slowly, the more than three million living American men who are diagnosed with prostate cancer are at much higher risk for dying of heart attacks than they are of dying of their prostate cancer.
Prostate infections are extremely difficult to diagnose and treat because many doctors do not order the right tests and even when they make the correct diagnosis, they often fail to treat the condition long enough or they fail to treat infected partners.
A study that followed 13,000 men from 1971 to 2009 shows that men who keep a high level of fitness from their forties onward have a one third lower risk overall of dying from certain cancers after age 65 (JAMA Oncology, March 27, 2015). Fitness was measured by their ability to keep on running...
The U.S. Food and Drug Administration (FDA) requires makers of prescription testosterone products to have a label stating that taking testosterone may cause heart attacks, strokes and death, and it is approved only for men who have low testosterone levels due to disorders of the testicles, pituitary gland, or brain,
Premature ejaculation means that a man doesn't last as long as he wants to, regardless of time or strokes. Ninety percent of teenage boys suffer from this condition, while 90 percent of men over the age of 55 suffer from delayed ejaculation.
It should bother you that the nutritional supplement industry is unregulated because there is no way to tell what a supplement contains. Several different studies have shown that at least one third of nutritional supplements do not supply what is on the label.
I have been asked by hundreds of men who have been diagnosed with prostate cancer whether they should be treated with surgery or radiation, or just watch and wait. One study showed that men under 60 who are in excellent health and are destined to live long lives may benefit from early treatment (1). Six years later, 4.6 percent of men who had surgery had expired, compared to 8.9 percent of those who did not have surgery.
Metabolic syndrome and type II diabetes are characterized by high blood sugar, insulin, and triglycerides, low HDL and a fatty liver and obesity. Of 490 male adults, average age 58 years old, 37 percent with lower urinary tract obstruction (LUTS) had metabolic syndrome.
Researchers reviewed the medical records of 55,593 men who were given testosterone for low testosterone levels and/or sexual dysfunction and compared them to men who received Viagra or Cialis but no testosterone. After three months, the risk for heart attacks was double in the testosterone group for all of the men older than 65,...
As men age from 50 to 70, their testosterone levels drop more than 40 percent, causing them to become fatter, and less sexual, muscular and assertive and have smaller, weaker bones (7,11). Twenty percent of men aged 60-80 years have testosterone levels below the lower limit of normal.
