６５歲以上男性接受雄激素療法可以提高性功能，行走的能力， 和改善情緒。
報道: As men age, their testosterone levels decrease, but prior studies of the effects of administering testosterone to older men have been inconclusive. Now, a new study shows testosterone treatment for men age 65 and older improves sexual function, walking ability and mood, according to findings published in the New England Journal of Medicine by a team of researchers from 12 medical centers, including Cora E. Lewis, M.D., of the University of Alabama at Birmingham.
The Testosterone Trials, or TTrials, are a coordinated group of seven trials, and researchers have analyzed the results of the first three — sexual function, physical function and vitality. They found that testosterone treatment increased the blood testosterone level in the study subjects to the mid-normal range for younger men.
Testosterone treatment led to modest improvements in all aspects of sexual function, including sexual activity, sexual desire and the ability to get an erection. It also resulted in small improvements in indexes of mood and depression and some but not all measures of physical function. Treatment did not improve overall energy level.
With 51,085 men screened and 790 who qualified, the TTrials are now the largest trials to examine the efficacy of testosterone treatment in men 65 and older whose testosterone levels are low due seemingly to age alone.
Lewis says men considering testosterone treatment should consult their doctor.
The TTrials were supported by a grant from the National Institute on Aging of the National Institutes of Health and funding from other institutes of the NIH.
