Is it the doings of a primary sex hormone called testosterone, long associated with social dominance, virility and strength? Many scientists have explored the role of hormones and conduct, whether in school playgrounds, sports, war or bedrooms. Now a Universite de Montreal study of five-month old twins is among the first to tease out the contribution of genetic and environmental factors to circulating levels of this chemical. The research with infant twins suggests that the environment plays a greater role than genes when … Read more »

Reading Time: 2 minutes London, May 9 : Taking testosterone supplements may help older obese men in cutting their excess weight, researchers have suggested.

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 minutes ScienceDaily (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 minutes It's a rough life for the Tsimane, an isolated indigenous group in Bolivia. They make a living by hunting and foraging in forests, fishing in streams and clearing land by hand to grow crops. Their rugged lifestyle might imply that Tsimane men have elevated testosterone to maintain the physical activity required to survive each day. But new research shows that Tsimane ("chi-MAH-nay") men have a third less baseline testosterone compared with men living in the United States, where life is less physically demanding. And unlike men in the U.S., the Bolivian foragers-farmers do not show declines in testosterone with age. … Read more »
