Study: Testosterone Makes Young Male CEOs Do Crazy Things

(Sept. 9) -- Young male executives, whose testosterone levels typically exceed those of their older colleagues, are more likely to coordinate and execute aggressive business takeovers -- and subsequently let the deals crash and burn. That's the contentious result emerging from a decidedly uncontentious location after Canadian researchers checked out the characteristics of CEOs implicated in 350 merger-and-acquisition bids made by public American companies between 1997 and 2007. "Young male CEOs appear to be combative: They are 4 percent more likely to be acquisitive and, having initiated an ...

Why Men Cheat: Science Says 'New' Women Boost Testosterone

Andrew Sullivan links to a blog post on male sexuality by Christopher Ryan, co-author, along with Cacilda Jetha, of the new book "Sex at Dawn: The Prehistoric Origins of Modern Sexuality." Ryan looks at the eternal question: Why do men, in particular middle-aged men, have affairs? One's tempted to answer the question -- or a revision of it (why do men sleep with other women -- or men?) -- with Sir Edmund Hillary's response to someone who asked him why he wanted to climb Mount Everest. "Because it's there," he said. Sexual opportunities are out there, too. And while there are myriad reasons ...

Male Menopause: A Real (But Rare) Phenomenon

The oft disputed phenomenon of "male menopause" is a reality for some aging men -- but it's much less common than many researchers had previously thought. That's the result of a new study, published in the New England Journal of Medicine, which concludes that fewer than 2 percent of the male population experiences the condition. Researchers at the University of Manchester and the University College London evaluated the testosterone levels of 3,369 men between 40 and 79. The men were also surveyed on their sexual, physical and psychological well-being. From there, the team managed to ...

Testosterone Turns on Distrust in Women, Study Says

(May 25) -- A boost in testosterone can turn women into cynical, suspicious skeptics, according to a new study. It's a finding that could help scientists understand how the brain has adapted to spur competition for social rank and better access to resources. Testosterone, often identified as a male sex hormone, is naturally prevalent -- to a lesser extent -- in females. The hormone has already been linked to aggressive behavior and a competitive urge, but scientists are still unsure of the mechanism at work. The new study, published this week in the Proceedings of the National Academy of ...

Men's Testosterone Drops When Their Candidate Loses

The last time you watched your candidate lose an election, did it feel like you were losing the election yourself? Your body's biochemistry may have thought so. A study in science journal "PLoS One," from researchers at Duke University and the University of Michigan, showed that following the announcement of the 2008 election results, male supporters of John McCain and other candidates who lost experienced a dramatic drop in testosterone. In contrast, men who supported Barack Obama maintained relatively stable levels of testosterone after learning he had won. In addition to the lowered levels ...
