American Testosterone Clinic for Men

Reading Time: 2 minutesWashington, Feb 1 (ANI): Researchers have found that low testosterone levels occur five times more often among men who take long-acting instead of short-acting opioids for chronic pain. While it has been known that opioids cause low testosterone in men, this study is the first to show a significant difference in risk between short-acting (immediate release) and long-acting opioids. The 81 men in the retrospective study were between 26 and 79 years old (median age 51) and were seen in the chronic-pain clinic at Kaiser Permanente's Santa Rosa Medical Center (Calif.) between January 2009 and June 2010. All of the … Read more »

Reading Time: 2 minutesA testosterone test checks the level of this male hormone (androgen) in the blood. Testosterone affects sexual features and development. In men, it is made in large amounts by the testicles . In both men and women, testosterone is made in small amounts by the adrenal glands , and in women, by the ovaries . The pituitary gland controls the level of testosterone in the body. When the testosterone level is low, the pituitary gland releases a hormone called luteinizing hormone (LH). This hormone tells the testicles to make more testosterone. Before puberty, the testosterone level in boys is normally … Read more »

Reading Time: 2 minutesScienceDaily (May 10, 2012) By comparing the testosterone levels of five-month old pairs of twins, both identical and non-identical, University of Montreal researchers were able to establish that testosterone levels in infancy are not inherited genetically but rather determined by environmental factors. "Testosterone is a key hormone for the development of male reproductive organs, and it is also associated with behavioural traits, such as sexual behaviour and aggression," said lead author Dr. Richard E. Tremblay of the university's Research Unit on Children's Psychosocial Maladjustment. "Our study is the largest to be undertaken with newborns, and our results contrast with the … Read more »

Reading Time: 2 minutesApr. 3, 2013 Low testosterone levels may herald the subsequent development of rheumatoid arthritis in men, suggests research published online in the Annals of the Rheumatic Diseases. Sex hormones are thought to play a part in the development of rheumatoid arthritis, and both men and women with the condition tend to have lower levels of testosterone in their blood than healthy people. But it is not clear whether this is a contributory factor or a consequence of the disease. The researchers based their findings on participants of the Swedish Malmo Preventive Medicine Program (MPMP), which began in 1974 and tracked … Read more »

The results, published online in PLoS Genetics, also reveal that some of the genetic markers for this protein are near genes related to liver function, metabolism and type 2 diabetes, demonstrating an important … Read more »

Reading Time: 2 minutesTUESDAY, May 28 (HealthDay News) -- After winning a team competition against strangers or rivals, men's testosterone levels increase. But when they're victorious against friends, their testosterone levels remain the same, according to a new study. This response during group competition is rooted in evolution and related to how humans form coalitions or alliances in warfare, the researchers said. "One interesting thing about humans is that we are the only animal that competes in teams," Mark Flinn, a professor of anthropology at the University of Missouri, said in a university news release. "Our hormonal reactions while competing are part of … Read more »

Reading Time: 2 minutesLondon, May 9 : Taking testosterone supplements may help older obese men in cutting their excess weight, researchers have suggested. In a study, hormone-deficient men were given testosterone supplements in a similar way to HRT for older women. Men lost an average of 16kg over five years when testosterone levels were increased back to normal. But experts warn that supplements may not be the answer due to possible risks of prostate cancer and heart disease, the BBC reported. "The notion that this is a quick fix for obese older men is, as always, simplistic. It is far more sensible and … Read more »

Reading Time: 2 minutesSep. 30, 2013 Boosting testosterone can promote generosity, but only when there is no threat of competition, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The 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," explains lead researcher Maarten Boksem of Rotterdam School of Management, Erasmus University (RSM) in the Netherlands. "But it can also induce … Read more »

Reading Time: < 1 minuteTestosterone thought to cause 'man flu' Men have a reputation for being sooks when it comes to winter colds and flu but researchers believe "man flu" really does exist and the culprit is testosterone. US and French scientists have found evidence that testosterone plays a key role in making men's immune responses more sluggish than women's. It has long been thought that women's immune systems are generally stronger and respond more quickly to infections and vaccinations than that of males, but the cause has been unknown. The new study blames testosterone for dampening the immune response, suggesting men with high … Read more »

Reading Time: < 1 minuteWashington, Feb 20 (IANS) Male superiority over females in spatial navigation may just be a "side-effect" of testosterone, according to an analytical study. Previous studies have shown that women who take testosterone see an improvement in their spatial navigation skills, says Justin Rhodes, professor of psychology at the University of Illinois, who led the study. Some argue, for example, that males' slight, but significant, superiority in spatial navigation over females is probably "adaptive", meaning that during evolution, the trait gave males an advantage that led them to have more offspring than their peers, the journal Quarterly Review of Biology reports. … Read more »
