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.
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.
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.
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.
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.
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.
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.
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.
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,
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").
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.
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 depressing study from Harvard School of Public Health showed that loss of hair on the top of the head markedly increases a man's chances of suffering a heart attack, and the more hair he loses, the more likely he is to suffer a heart attack (1). Men with male pattern baldness have higher than...
Many doctors recommend that every man over 40 get a blood test called Prostate Specific Antigen to check for prostate cancer. Prostate Specific Antigen is made by prostate cells and is released into the bloodstream. Large prostates have more PSA, so a rise in PSA means that the gland is enlarging rapidly, which can be a sign of cancer or that the prostate is irritated by infection.
Lifestyle appears to be a major factor in whether you develop prostate cancer. An excellent review of the world’s scientific research concludes: "Heart healthy equals prostate healthy . . . the best dietary advice for prostate cancer prevention or management seems to include: increasing fruits and vegetables, replacing refined carbohydrates with whole grains, reducing...
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.
Three of 100 men suffer from Peyronie's disease, a bending of the penis during erection. The penis contains balloons that fill with blood to cause an erection. These balloons can develop a scar that prevents them from expanding normally during an erection, causing the penis to bend toward the scar.
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.
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.
A study from the National Cancer Institutes showed that taking more than 100 mg of zinc supplements a day doubles a man's chances of developing advanced prostate cancer. There are hundreds of products on the market today that contain zinc and they are advertised to help treat the prostate, help prevent prostate cancer, help treat an enlarged prostate, treat impotence, increase sexuality, increase ejaculation volume, and make a man more potent. All of these claims are unsupported by scientific data.
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.
Research has shown that most cases of swollen testicles do not need to be corrected by surgery. Swollen, painless testicles are usually caused by varicoceles, large veins full of blood on the outside of the testicles; or hydroceles, a sac of fluid around the testicles. Less common causes include infection or a tumor.
Doctors do not need to biopsy every man with a high PSA screening blood test for prostate cancer. Most patients become infected from the procedure, 20 percent suffer severe pain, 10 percent require strong pain medicines, and 15 percent of previously potent patients report that they can't get an erection one month later.
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,...
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.
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...
