Reading Time: 2 minutesWomen may drool over George Clooney and Brad Pitt, but their lust may be more for these macho guys' immune systems than their pretty faces and chiseled abs, new research suggests. Men with high levels of the sex hormone testosterone are seen as more hunky — and these same men have stronger immune responses, researchers report Tuesday (Feb. 21) in the journal Nature Communications. The findings suggest that women may be attracted to manly facial types because the macho look signals good health. Researchers led by Fhionna Moore of Abertay University in the United Kingdom recruited 74 Latvian men in … Read more »

Reading Time: 2 minutesWashington, October 11 (ANI): Testosterone is considered the male hormone, standing for aggression and posturing, but researchers from the University of Bonn have now revealed that this sex hormone surprisingly also fosters social behaviour. In play situations, subjects who had received testosterone clearly lied less frequently than individuals who had only received a placebo, researchers around Prof. Dr. Armin Falk, an economist from the University of Bonn, found. The hormone testosterone stands for typically male attributes - it fosters the forming of the sexual characteristics, increases libido and muscle building. Women also have this sex hormone, but to a much … Read more »

Reading Time: < 1 minuteLondon, Dec 9 (IANS) Testosterone shots can not only overcome low libido in men but also protect them against heart attacks, says a US study. A five-shot course of the hormone boosted male sex drive as well as their fitness levels, mood and their ability to concentrate. They also reported weight loss. The incidence of low libido dropped from 64 percent to 10 percent after treatment. The study was conducted on men with medically deficient levels of testosterone, known as hypogonadism. Experts believe the findings could be relevant to the far larger group of ageing men whose testosterone has simply … Read more »

Reading Time: 1 minuteFRIDAY, May 31 (HealthDay News) -- Male athletes who choose to wear the color red in competition have higher levels of the male hormone testosterone than men who pick the color blue, a British study suggests. Men who wear red could be sending an unconscious signal about their competitiveness to their opponents, the researchers suggested in the study, which is to be published in an upcoming issue of the journal Psychological Science. "The research shows that there is something special about the color red in competition, and that it is associated with our underlying biological systems," study leader Daniel Farrelly, … Read more »

The findings, published in Proceedings of the National Academy of Sciences, suggest that testosterone levels may partially explain why men often have weaker responses to vaccines than women. The study, led by researchers at Stanford University, was supported in part by the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health.

Reading Time: 2 minutesWhen most of us hear the word testosterone we think of puberty and men in their twenties sowing their oats. We also tend to think of bulky body builders pumped up and maxed out. However testosterone plays many more roles in the health of both men and women than many of us realize. And low levels of testosterone in both sexes may cause serious negative health consequences. Whats more is it seems that testosterone levels in both men and women are getting lower at earlier ages. In fact, its estimated that twenty-five percent of men over the age of forty-five … Read more »

Reading Time: 2 minutesIn the early 1900s, Kansas was home to one of the most financially successful doctors in American history John Brinkley who practiced in Milford. He became famous or infamous to some for procedures which involved the transfer of tissue from one species to another; specifically, transplanting goat testicles into humans as a treatment of sexual dysfunction. Brinkley was scrutinized and eventually exposed as a charlatan and stripped of his license to practice medicine; however, his work was partially responsible for inspiring serious investigators to discover testosterone. In the mid-1930s, researchers Adolf Butenandt and Leopold Ruzicka were awarded the Nobel Prize … Read more »

Dr. Gary Wittert, professor of medicine at the University of Adelaide in Adelaide in Australia, and colleagues analyzed testosterone levels in more than 1,500 men who had measurements taken at two clinic visits five years apart. Men who had abnormal values, were taking medications or had medical conditions known to affect hormones, were excluded. The men included in the analysis involved 1,382 men -- ages 35 to 80 … Read more »

Reading Time: 1 minuteBy Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on October 1, 2013 New research suggests testosterone can promote generosity, but only when there is no threat of competition. The study is published in Psychological Science, a journal of the Association for Psychological Science. Study findings show that testosterone is implicated in behaviors that help to foster and maintain social relationships, indicating that its effects are more nuanced than previously thought. Testosterone may mediate competitive and potentially antisocial behavior when social challenges or threats need to be confronted and handled, said lead researcher Maarten Boksem, Ph.D., … Read more »

Use of testosterone therapy has increased dramatically over the past decade, according to a new study. But experts worry that too many men may be taking the supplements without understanding the potential risks. Researchers at the University of Texas Medical Branch at Galveston pointed out that the development of new drugs, particularly topical gels, also likely played a role in this trend. The study, published in the current … Read more »

Reading Time: 3 minutesWhile there are numerous hormones we may aptly label important in-terms of proper function and health, for men the hormone testosterone is of great importance. Both men and women require testosterone for a well-functioning body but men do so in far higher amounts then their female counterparts. While a very important hormone and largely misunderstood, testosterone is easily one of the most exciting hormones we can discuss, especially as it pertains to performance enhancing; in-fact, we can confidently say it is the most important hormone in the performance enhancing game. Without adequate levels of testosterone our goals will largely not … Read more »

Well, low testosterone levels (or Low T) can be responsible for the male version (man-o-pause?) and it can affect men in many of the same ways. Testosterone, known as the male hormone, is responsible for the typically male characteristics that appear during puberty such as facial hair growth, a deeper voice and muscle growth. Women produce testosterone too, but in much lower quantities than men. Mandy Kendall During adulthood, testosterone helps maintain … Read more »

Bacteria cover our skin, get to our food before we have the chance to absorb it, and in many cases stay helpfully out of the way of the immune system. Given all that, it shouldn't be a surprise that we're finding that bacteria can have significant effects on the human body in ways that go well beyond causing an infection.

The hormone testosterone plays a role in this changing song behavior. Researchers at The Johns Hopkins University have found that introducing testosterone in select areas of a male canary's brain can affect its ability to successfully attract and mate with a female through birdsong. They also found that enhancing song activity based on testosterone in one brain area can change the size of a separate brain area that regulates song … Read more »

Reading Time: 2 minutesJuly 26, 2013 The results of a new study by neurological researchers at Rush University Medical Center show that a sudden decrease of testosterone, the male sex hormone, may cause Parkinson's like symptoms in male mice. The findings were recently published in the Journal of Biological Chemistry. One of the major roadblocks for discovering drugs against Parkinson's disease is the unavailability of a reliable animal model for this disease. "While scientists use different toxins and a number of complex genetic approaches to model Parkinson's disease in mice, we have found that the sudden drop in the levels of testosterone following … Read more »
