Elderly men with low levels of testosterone or other sex hormones have twice the likelihood of having declining physical function over two years’ time compared with their peers who have the highest hormone levels, a new study from Australia finds. The results were presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014. “We also found that increasing muscle weakness – possibly due to decreasing testosterone concentration in the blood – could explain most of this relationship,” said Benjumin Hsu, MPH, the study’s principal investigator and a PhD candidate at the University of Sydney. Although testosterone levels and the ability to perform self–care activities both decrease with age, it is unclear whether one or the other is a cause or an effect of aging, or if they are both due to a common third cause, Hsu said.
