Testosterone has a variety of well-known effects including bone accrual, building and maintaining muscle mass, and promoting erectile function and libido.1 Of the 5 mg of testosterone manufactured daily by the testes, about 6% to 8% is metabolized by 5-reductase to make 0.3 mg of dihydrotestosterone (DHT).2 Local conversion of testosterone to DHT by 5-reductase in the skin and prostate can create locally high concentrations of the potent androgen DHT. Dihydrotestosterone stimulates prostate growth … Read more »

Reading Time: < 1 minuteHigh levels of testosterone might make men more trustworthy, a study has found. The male hormone, which boosts libido and builds muscle, is often associated with aggression and anti-social behaviour. But testosterone-fuelled hunks may also be less likely to lie and cheat than some of their brothers, the research suggests. Scientists boosted the testosterone levels of 46 men by smearing their skin with a gel containing the hormone. Another 45 men were treated with a "dummy" placebo gel lacking any testosterone. Both groups were then asked to take part in a behavioural study which involved playing a simple game of … Read more »

Reading Time: 2 minutes-- TV ads tout testosterone treatments for "low T," but surprising new research shows a different hormone may play a role in less sex drive and more fat as men age. Estrogen the female hormone is needed by men, too, and the study gives the first clear evidence that too little of it can cause certain "male menopause" symptoms. "A lot of things we think are due to testosterone deficiency are actually related to the estrogen deficiency that accompanies it," said Dr. Joel Finkelstein of Massachusetts General Hospital. He led the U.S.-government funded study, which appears in Thursday's New England … 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 genetic connection … Read more »

Reading Time: < 1 minuteScientists said Monday they have new evidence about why women live longer than men, from a study of historical data showing castrated Koreans far outlived their non-eunuch contemporaries. The study, published in the scientific journal "Current Biology,'' used detailed genealogical records of the Imperial nobility during Korea's Joseon dynasty, which spanned more than 500 years from the late 1300s to the early 1900s. According to the data, most men, including kings and royal family members, died in their late-40s or early-50s. But noble-class eunuchs _ men who were castrated either by accident or because of social benefits _ lived, on … Read more »

Reading Time: < 1 minuteLondon, Mar 25 : Green tea could inadvertently help athletes who dope on testosterone as it has been found to mask the hormone's presence in urine testing. Although testosterone is naturally present in the human body, unnatural amounts of it can be spotted by detecting its unusual ratio to another hormone called epitestosterone in urine. Declan Naughton and colleagues at Kingston University London conducted lab tests and discovered that compounds called catechins - found in green and white tea but not in black - inhibit an enzyme called UGT2B17. This enzyme attaches glucuronic acid to testosterone, making it more likely … 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: 2 minutesLow testosterone can dim a man's sex drive, performance in bed, energy, and motivation. It can also have some harmful effects. When needed, testosterone replacement therapy (TRT) can boost T levels back to normal and return him to the man he used to be. "Despite all the recent advertising campaigns, awareness of low T and its importance for mens health remains very poorly recognized by both the public and by physicians," says Abraham Morgentaler, MD, director of Men's Health Boston and author of Testosterone for Life: Recharge Your Vitality, Sex Drive, Muscle Mass, and Overall Health. Still, there are also … Read more »

Reading Time: 2 minutesTestosterone is hugely important for muscle and bone strength, sex drive, and energy levels. While both men and women produce this hormone, men typically produce it in larger amounts and tend to notice more when their levels start to droop. Testosterone production naturally starts to decrease around age 30 for most men, and can result in everything from tiredness to erectile dysfunction. By that point, many men are working hard to keep their testosterone (or "T") levels high with supplements, diet, and exercise, but there are a few things you might be doing to unintentionally hinder your efforts. Here are … Read more »

Reading Time: 3 minutesHypogonadism is a medical term which describes a diminished functional activity of the gonads the testes and ovaries in males and females, respectively that may result in diminished sex hormone biosynthesis and impaired gamete production and/or regulation. In layman's terms, it is sometimes called "interrupted stage 1 puberty". Low androgen (e.g., testosterone) levels are referred to as hypoandrogenism and low estrogen (e.g., estradiol) as hypoestrogenism, and may occur as symptoms of hypogonadism in both sexes, but are generally only diagnosed in males and females respectively. Other hormones produced by the gonads which may be decreased by hypogonadism include progesterone, DHEA, … Read more »

Reading Time: 2 minutesFor men with low testosterone, taking testosterone along with Viagra may not help their erections more than if they only took Viagra, a new study shows. There were lots of reasons to think that it would work," Boston University researcher Matthew Spitzer, MD, says of the common practice of combining the two treatments. It was surprising to me that it didnt. The study, published in the Annals of Internal Medicine, was a good one and the largest of its kind, but will it change practice? In my opinion, no," says urologist Jason Hedges, MD, PhD, of Oregon Health and Science … Read more »

Reading Time: 2 minutesScienceDaily (Oct. 10, 2012) Testosterone is considered THE male hormone, standing for aggression and posturing. Researchers working with Dr. Armin Falk, an economist from the University of Bonn, have now demonstrated that this sex hormone surprisingly also fosters social behavior. In play situations, subjects who had received testosterone clearly lied less frequently than individuals who had only received a placebo. The results have just been published in the Public Library of Science's international online journal PLoS ONE. The hormone testosterone stands for typically male attributes -- it fosters the forming of the sexual characteristics, increases libido and muscle building. Women … Read more »
