Strong words, I know – but time and again science has proven that the prostate specific antigen (PSA) screening is unreliable at best, downright dangerous at worst. Even the Journal of the American Medical Association (JAMA) spoke out in opposition to the PSA, Continue reading
Women taking fish oil are sometimes pleased – or alarmed – to discover a common side effect: becoming spontaneously orgasmic. On higher-than-normal doses, women often see increased libido and enjoy faster, stronger and more plentiful orgasms. As outlined in The Orgasmic Diet, this and several other dietary factors contribute to adding explosive heat to the bedroom, but men beware: following this regimen will likely only lead to premature ejaculation.

People who drink iced tea may be putting themselves at greater risk for developing painful kidney stones, a new study indicates.
Researchers from Loyola University Medical Center explained that the popular summertime drink contains high levels of oxalate, a chemical that leads to the formation of small crystals made of minerals and salt found in urine. Although these crystals are usually harmless, the researchers cautioned they can grow large enough to become lodged in Continue reading
- The longest ever human aspartame study, spanning 22 years, found a clear association between aspartame consumption and non-Hodgkin’s Lymphoma and leukemia in men
- Leukemia was associated with diet soda intake in both sexes
- The study was done out of Harvard but after caving to pressure from industry, a press release was issued that minimized the impact of the study
- The long-term nature of this study is crucial as one of the primary tricks companies use to hide Continue reading
If you’re a guy and don’t know what Kegel exercises are, then read on. Kegel exercises are probably the easiest and most convenient exercises you can do to help improve your urinary, prostate and sexual health, and you can do them without putting on athletic shoes or breaking a sweat. In fact, no one will even know you are doing these exercises, even if you’re in a crowd or waiting in line at the bank.
What Are Kegel Exercises?
For the uninitiated, Kegel exercises (sometimes referred to as pelvic floor exercises) involve tightening your pubococcygeus (PC) muscle, Continue reading
In 2003, a Western study proved that real acupuncture was superior to sham acupuncture in treating impotence. Chinese researchers Continue reading
Studies have consistently reported that women require reading glasses or bifocal lenses earlier than men. According to a recent Investigative Ophthalmology & Visual Science paper, the gender difference Continue reading
Most of the really old don’t get it on. But if you keep yourself fit and in good health, you can keep having sex further into your golden years.
Unfortunately, those who live to be 100 don’t have much of a sex life as they near the century mark. The average man’s sex life ends around age 70. For women, it’s usually over at age 66. But, says a study at the University of Chicago, published in the British Medical Journal, if you keep yourself in really good health and physical shape, you can squeeze out up to an extra seven years of sex.
“Interest in sex, participation in sex and even the quality of sexual activity were higher for men than women, and this gender gap widened with age,” said lead author Stacy Tessler Lindau, M.D., associate professor of obstetrics and gynecology at the University of Chicago. But the study also “affirms a positive association between later-life health, sexual partnership and sexual activity,” she said.
A consolation for older women, according to the scientists, is that many of them seem not to miss sexual activity after it ends. Continue reading
Narcissism has a higher health cost for men
The personality trait narcissism may have an especially negative effect on the health of men, according to a recent study published in PLoS ONE.
“Narcissistic men may be paying a high price in terms of their physical health, in addition to the psychological cost to their relationships,” says Sara Konrath, a University of Michigan psychologist who co-authored the study.
Earlier studies by Konrath and others have shown that the level of narcissism is rising in American culture, and that narcissism tends to be more prevalent among males. The personality trait is characterized by an inflated sense of self-importance, overestimations of uniqueness, and a sense of grandiosity.
For the new study, Konrath and colleagues David Reinhard of the University of Virginia, and William Lopez and Heather Cameron of the University of Michigan examined the role of narcissism and sex on cortisol levels in a sample of 106 undergraduate students. Continue reading
After only four years of problem drinking, a significant decrease in the function of the serotonin system in women’s brains can be seen. This is the system that regulates such functions as impulse control and mood. It takes 12 years before a corresponding decrease is seen in men. This is the conclusion of multidisciplinary research carried out at the Department of Psychology and the Sahlgrenska Academy at the University of Gothenburg, Sweden.
The research group in the multidisciplinary project Gothenburg Alcohol Research Project (GARP) has studied for the first time three of the major neurotransmitter substances in the brain in a single individual. They have studied a group of women and a group of men with alcohol dependence. The results will be published in January 2012 in the journal Alcoholism: Clinical & Experimental Research.
“We have used what is known as neuroendocrine techniques to show that it is principally the serotonergic system Continue reading
Two health conditions that go hand-in-hand are type 2 diabetes and obesity. On both fronts, the glycemic index (GI) comes into play. Let’s look at how you can use GI ratings for foods to your benefit in these areas.
1. GI and Diabetes
Many studies have shown that high-GI foods increase the risk of type 2 diabetes. One large one involving nearly 43,000 healthy men found that a diet of high GI and low- fiber foods did just this. Another study, of more than 65,173 healthy women, confirmed that having a high-GI diet and a low fiber intake increases diabetes risk. This one suggests that diabetes could be reduced in the U.S. if people ate more whole grains.
A large study of 14 previous studies with 356 diabetic patients clearly showed that the low-GI diet improved Continue reading
Most people know that they should get adequate levels of calcium every day in order to maintain strong bones, but researchers at Florida State University have conducted a study which suggests that prunes may also contribute to higher bone density.
In a year-long trial, the scientists instructed 55 of the participants to eat 100 grams of dried plums each day and 45 volunteers to consume the same amount of dried apples. All volunteers were female and took 500-milligram calcium supplements and 400 international units of vitamin D.
At the end of the study, researchers said that the women who ate prunes daily had significantly higher bone mineral density than their counterparts who ate apples. The scientists noted that this may be due to the fruit’s ability to prevent resorption, or bone loss.
Authors of the study Continue reading
We have all heard about the health benefits of resveratrol. It has been in the news for the past couple of years. Resveratrol comes from the skin of grapes and has been touted as an amazing cholesterol-buster and antioxidant.
It’s not surprising, then, that researchers at Colorado State University just completed a new study examining the health benefits of grape seed extract and resveratrol together.
The U.S. researchers found that grape seed extract could inhibit the growth of colon cancer cells in the laboratory. Colon cancer is the third leading cause of cancer deaths in men and women.
It seems that grape seed extract starts something called “apoptosis.” Apoptosis is a process in which cells are programmed to die. Unlike cell death due to injury, for example, apoptosis is a beneficial process. When the fetus is growing in the womb, apoptosis causes cell death in the fingers and toes, so that they can separate into individual digits. There are many, many other examples of beneficial cell death.
In this particular study, apoptosis appeared to kill off colon cancer cells before they could divide and multiply. In addition, grape seed extract and resveratrol together seemed to have an even more potent effect Continue reading
Researchers at National Jewish Health have discovered a type of cell that may contribute to autoimmune disease. The findings also suggest why diseases such as lupus, multiple sclerosis and rheumatoid arthritis strike women more frequently than men.
The cells, a subset of immune-system B cells, make auto antibodies, which bind to and attack the body’s own tissue. The researchers report in the August 4, 2011, issue of the journal Blood, that they found higher levels of these cells in elderly female mice, young and old mice prone to autoimmune disease, and humans with autoimmune diseases. National Jewish Health has applied for a patent for a method to treat autoimmune disease by depleting these cells.
“We believe these cells could be useful in the diagnosis Continue reading
Pharmacists of the University Jena analyze why men suffer more rarely from inflammatory diseases than women.
It’s all down to the testosterone: men are usually more muscular than women, they have deeper voices and more body hair. And – men are less susceptible to inflammatory diseases and allergies than women. This is also due to the male sex hormones as pharmacists at the Friedrich Schiller University Jena (Germany) have shown in a recent study.
“It is mostly women who are affected by diseases like rheumatoid arthritis, psoriasis or asthma“, Professor Dr. Oliver Werz from the Jena University explains. Although this is a fact known for some time, the reasons for these differences are largely unknown. As the Jena Professor for pharmaceutical and medical chemistry Continue reading
