Reading Time: < 1 minute This photo provided by Eli Lilly & Co. shows the drug Axiron. (AP Photo/Eli Lilly & Co.) Two years ago drugmakers spent 14-million dollars promoting prescription testosterone. Last year they spent 100-million dollars. And sales are soaring, topping two billion dollars in 2012. But Consumer Reports says most men dont need testosterone treatments. Even if youre worried about erectile dysfunction, treatment with testosterone usually isnt the answer. Erectile dysfunction almost always stems from other problems: reduced blood flow, emotional problems, or a drug side effect. And using testosterone treatments, which can cost $400 a month or more, has serious risks. … Read more »

Reading Time: 2 minutes Washington, Oct. 1 (ANI): Increase in testosterone can promote generosity, but only when there is no threat of competition, a new study has suggested. Lead researcher Maarten Boksem of Rotterdam School of Management, Erasmus University (RSM) in the Netherlands, said that they hypothesized that testosterone could perhaps also lead to prosocial behaviour if such behaviour would be beneficial for maintaining or obtaining social status. To test this hypothesis, the researchers had 54 female volunteers ingest a liquid solution several hours before participating in an investing game - some volunteers received a placebo solution, while others received a solution with added … Read more »

Reading Time: 2 minutes Chicago, July 27 : 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 … Read more »

Reading Time: < 1 minute Testosterone is considered the male sex hormone, although women do require trace amounts. It is produced in the testicles or gonads and is responsible for masculine development, muscle building, and virility. Levels normally decline about one percent annually after age 30. Testosterone is the steroid banned in most sports because of its dramatic effect on muscle mass and performance. The potential for excessive use and abuse of testosterone supplements is significant. Nevertheless, a wave of new supplements have recently hit the market. Signs and Symptoms: Fatigue, depression, and low sex drive are common features of testosterone deficiency.

Reading Time: 2 minutes In the industrialized world, women live at least five years longer, on average, than men. Scientists have attributed that difference to everything from healthier habits to hardier cells. Now, a study that analyzes the longevity of eunuchs, or castrated men, suggests that testosterone may play a part in shortening mens lives. The idea that testosterone, the male sex hormone, affects life span isnt new. Neutered dogs and other animals that have had their sources of testosterone removed often live longer than their intact counterparts. But studies on the connection between castration and longevity in humans are harder to come by, … Read more »

Reading Time: < 1 minute Boxing News Dr. Margaret Goodman and the Voluntary AntiDoping Association (VADA) have called for professional sports leagues to immediately adopt the Carbon Isotope Ratio (CIR) test for every screen used in testing for performanceenhancing drugs. To date, only fighters who participate in VADAs rigorous voluntary program undergo such testing. The recent positive tests for synthetic, or artificial, testosterone in professional and elite sports demonstrate that it is a problem at the highest levels of sport, said Dr. Goodman, President of VADA. Clearly, some athletes are choosing to use the substance because they know it is not tested for upfront. Its … Read more »

Reading Time: 2 minutes A new study on female hormones and sexual desire finds that estrogen, not testosterone, can boost libido in a woman's natural cycle, while progesterone deadens it, they say. Not coincidentally, this increase in desire works in favor of a woman's fertility. "We found two hormonal signals that had opposite effects on sexual motivation," said lead author James Roney of the University of California Santa Barbara. "Estrogen was having a positive effect, but with a two-day lag. Progesterone was having a persistent negative effect, both for current day, day before, and two days earlier." Roney and his team recruited undergraduate students … Read more »

Reading Time: 2 minutes Using a testosterone gel in addition to Viagra doesn't make the little blue pill work any better, according to a new study. The report's lead researcher said testosterone is typically prescribed to men who have both low testosterone levels and symptoms such as little interest in sex or low bone and muscle mass. But, "there's a tremendous amount of clinical judgment" that goes into that, said Dr. Matthew Spitzer, from the Boston University School of Medicine. "People are certainly being prescribed and using these medications at increasing amounts." According to Spitzer, studies have suggested that about one-quarter to one-third of … Read more »

Studying short-term spikes in the testosterone levels of Tsimane men, UC Santa Barbara anthropologists Ben Trumble and Michael Gurven have found that the act of chopping down trees -- a physically demanding task that is critical to successful farming and food production -- results in greater increases in testosterone than does a directly competitive activity such as soccer.
