article submitted by ronin187. thank you! washington (afp) – men who voted for republican john mccain in last year's us presidential election saw their testosterone levels fall significantly when they learned he had lost to barack obama, a study showed thursday. saliva samples collected from 163 men on the evening of the election showed that voters for both mccain and obama had similar testosterone levels when polling stations closed on the east coast, but the levels in mccain backers fell when obama was announced as the winner. by contrast, testosterone levels among men who voted for obama remained stable. taking into account the fact that polls shut and results were announced at night -- a time when men's testosterone levels usually decline -- the study said the level was equivalent to a rise. "political elections are dominance competitions. when men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels fall," said the study, published online by the public library of science (plos one). supporters of mccain or libertarian party candidate bob barr -- who the study noted didn't have a hope of getting elected -- showed "significantly larger testosterone decreases" than obama supporters from the time when polls closed to 40 minutes after obama was declared the winner. source
testosterone comes in a small dose but has huge consequences. explore some of the indicators and effects.
men who are worried about the recession could suffer reduced levels of testosterone, a doctor has warned. chronic stress caused by financial worries, redundancy or working longer hours may cause levels of the hormone to drop, dr richard petty said. testosterone is linked to sexual function, circulation and muscle mass, as well as mood, memory and concentration. previous studies have shown a link between chronic stress and lower testosterone levels. dr petty, who works at a private clinic for men, said: "when a man becomes grumpy or irritable, it's easy to blame work or simply the effects of ageing. "in the short-term, stress can increase levels of testosterone and this is useful to help people respond quickly to pressures and new situations. "but chronic stress, which is ongoing, is a major factor in the decline of testosterone. "chronic stress occurs all too frequently due to our modern lifestyles, when everything from high-pressured jobs to unemployment keeps the body in a state of perceived threat." lower levels of the hormone can cause irritability, lethargy, low sex drive and a lack of concentration. dr petty advised men to reduce their stress levels as much as possible by getting enough rest, eating healthily and exercising. source
