"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.

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.

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.

US and French scientists have found evidence that testosterone plays a key role in making men's immune responses more sluggish than women's.

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 »

Reading Time: 2 minutesTreatments purporting to offer "male rejuvenation" and combat the effects of aging have become popular in recent years, but such claims are not backed up by science, experts say.

However, studies examining the effects these treatments are lacking, and there's little evidence to support their use in men who don't have hormone deficiencies, experts say.
